Description

DEVICE FOR ADVANCED CHESS GAMES

AND METHOD OF ITS USE

Technical field

The present invention relates to a chess game, and more precisely, to a new kind of chess game, namely, to a method and apparatus for playing advanced chess using modern technical capabilities.

State of the art

There is a method of playing chess between two players who take turns to perform an action to move a piece on the playing field, placed on a chessboard or chess table. The playing field has sixty four equal squares, alternately colored in light and dark colors. To limit the time for thinking about moves in chess competitions, a chess clock is used, each of which has a time counter connected to two indicators and to the control unit. At the beginning of the game, players have an equal number of pieces and pawns: one player has light colored pieces (white), and the other has dark (black) pieces. Each set of pieces contains a king, a queen, two rooks, two bishops, two knights and eight pawns each. White starts the game; the right to play white is usually determined by lot. During his turn, the player must go to one of his pieces, except castling. Skipping moves is not allowed. This set of features is preserved in almost all variants of well-known advanced chess, since these variants are mainly aimed at their constructive implementation or insignificant adjustment of the rules of the game of chess. As an example, let us cite two such improved versions of chess. In the first embodiment, described in US patent JVs 5903016 BA (CL 7A 60 F 3/02, 1999), disclosed is a method of playing chess, which helps to increase interest in the game process due to a slight change in the above rules. In the second embodiment described in US patent JMa 6082596 BA (CL 7 A 60 F 3/02, 2000), such a device and method for playing chess is disclosed in which the central pawns differ from other pawns not only in size, but also in the way movement on the board.

The disadvantage of a chess game held both within the framework of official competitions and among amateurs is, on the one hand, the low level of some chess games, and on the other, their result, often not reflecting the general logic struggle, when having achieved a winning or a draw position a chess player reduces a game to a draw or loses it altogether, making mistakes that are not adequate both to the level of competition and to his own class. This reduces the spectator's interest in chess competitions and discredits modern chess as a logical game. It should be noted that in the context of the deep development of chess theory, in particular the endgame theory, the player’s intellectual creative potential is involved somewhere in the middlegame region, and to achieve success it is often sufficient to determine, firstly, the moment of the fracture, and secondly , to find only one or several moves during which the transition to the end is achieved either with extra material, for example, a pawn, or with a positional advantage. The search process for such solutions is the quintessence of modern chess, because due to the high entropy of chess positions in the middle game, the process of searching for new moves and continuations takes place with a great deal of art, which is the main attractive force of chess. However, as noted above, due to lack of time or lack of energy spent just to create a chess piece of art, a chess player often makes mistakes in technical positions, which negates his entire previous game.

The drawbacks of chess, which limit their widespread use in the world at the amateur level, and therefore reduce the number of fans and fans, who are ultimately consumers of the "chess product" that exists in various forms (television broadcasting of chess competitions, chess computers, chess literature, chess clocks and the like), their relatively high complexity as compared to other games, for example, computer games, also applies. This is due to the need to remember a large volume of opening options, as well as to perform tedious counting work during the game, associated with the tactical justification of the intended chess move.

In order to eliminate these shortcomings, in 1998 an attempt was made to create a new type of chess - advanced chess (advapsed chess). This method consists in using a computing device by at least one of the two players before the next random movement of their chess pieces on the playing field, and the above use of the computing device The equipment is made by the interaction of this player with the appropriate input device and display device included in the computing device ("64 - Chess Review", JN ° 7, 1998, S. 24 - 26). However, a practical test (for example, in the advanced chess match between G. Kasparov and V. Topalov) of advanced chess revealed their main drawback - the different influence on the level of the game of chess players of a computing device made, for example, in the form of a personal computer. The effect of various influences is expressed in the fact that a computing device “helps less” to a stronger player and vice versa. Another drawback of advanced chess is obviously that they cannot be played by those chess players whose game level is inferior to that of the computing device itself. In this case, these chess players will simply repeat the chess moves offered by a computing system that includes one or more computers. In accordance with the foregoing objective of the present invention is to provide such a method of playing advanced chess that does not have the above disadvantages.

Disclosure of invention

The objective of this invention is to create such a method of playing advanced chess, which, firstly, would eliminate the effect of various effects of computing devices on chess players with different levels of play, and secondly, would provide an opportunity for advanced players to play chess games which are inferior to the level of the game of the computing device itself.

The problem is solved in that a device for playing advanced chess, containing a playing field, divided into squares of two alternating colors, a set of chess pieces, a chess clock in which there is a time counter connected to two indicators and to the control unit, a computing a device connected to at least two input devices, to two display devices, as well as to a means for obtaining data on the location of chess pieces on the playing field, further comprises a control unit available Stu associated with the computing device, which in turn is connected to a chess clock control node.

To use this device, a method of playing advanced chess is proposed, which consists in alternately moving players their chess pieces on the playing field during the playing time set for each player on the chess clock, and in the use by each of the players of the computing device associated with the first input device, with the second input device, with the first display device, with the second display device, and also with means for obtaining data on the location of chess pieces on the playing field, while through the access control unit, players are blocked from accessing the computing device, and at any time during the game one of the games A shackle unlocks two display devices by interacting with a corresponding input device connected to an accessibility control unit, after which, using a computing device, the player calculates and displays data on the movement of a chess piece on the playing field on the corresponding display device.

Other features and advantages of this invention will be clear from the detailed description, as well as from paragraphs 1 to 13 of the claims. Brief Description of the Drawings

FIG. 10 depicts a second embodiment of a block diagram of an advanced chess game algorithm. The best embodiments of the invention

When describing the best options for implementing this invention, for the convenience of considering the description, all abbreviations in parentheses after underlined words will refer to their initial letters. In Fig. L, the number 1 denotes a device for playing advanced chess

(UIPS) between two players. We will name one player the first player (PI) 2, and the other the second player (VI) 3. A device for playing advanced chess includes a chess clock (W) 4, having two indicators - indicator (IND) 5 and IND 6, this, by pressing VI 3 on button 7, the process of counting time T ₁ on IND 5 starts, and by pressing on button 8, the process of counting time T ₂ on IND 6 is started. At the start of counting on IND 5, the time TJ on IND 6 is recorded during the game time T ₂ on the other hand, at the start of the reference time T ₂ to 6 IND accumulated during Ti time of the game is recorded on IND 5. On the upper plane UIPSH 1 shows the playing field (SP) 9 It is of a square-shaped box separated into squares of two alternating colors. Light squares are called white fields, and dark squares are called black fields. A set of chess pieces consists of two groups of chess pieces. The first group 10 includes figures of light color (white), and the second group 11 includes figures of dark color (black). In each group of chess pieces there is a king 12, a queen 13, two rooks 14, two bishops 15, two horses 16 and eight pawns 17. In addition to PI 9, two fields 18 and 19 can be applied to the surface of UIPSH 1, inside which there are symbols used to designate each field, for example, in the process of recording individual moves. According to the rules for using algebraic chess notation, letters of the Latin alphabet (from "a" to "h") are inside the field 18, and Arabic numbers (from "1" to "8") are inside the field 19. In addition, each figure has its own letter designation, in particular, in Russian: king - Kp, queen - F, rook - L, bishop - C, horse - K; pawn designation - n is used only in the entry of positions, and is omitted in the entry of games. In order to indicate white and black fields, LEDs (LEDs) 20, parallel to fields 18, 19 and performing the functions of an additional display device (UO), are displayed on the surface of UIPSH 1. In addition, this UIPSH 1 contains two input devices (HC), made in the form of buttons 21, 22, two UO 23, 24 and two displays 25, 26, designed to display the number of chess moves. Description of HC containing only two buttons, due to the desire of the authors to describe the operation of the UIPSH, which has the simplest, from the point of view of practical implementation, design. In the further description, an option will also be considered in which the HC is made in the form of buttons 7, 8. Naturally, in other UIPS, the design of the HC can include any number of buttons or other known elements included in these devices.

In Fig.2 presents a diagram of UIPSH depicted in Fig.l. It includes an electronic chessboard (ESD) 27, which includes a means for obtaining data (SPD) on the location of chess pieces. The analog part of the SPD on the location of chess pieces consists of sixty-four pairs of conductive plates 28, 29 located under each white and black field of IP 9, and the digital part consists of a generator 30 and a comparison unit (BS) 31, containing sixty-four voltage comparators. The ESD 27 also includes a computing device (WU), made in the form of a microcomputer (MK) 32, connected, firstly, to two contacts 33, 34, connected with buttons 21, 22, and secondly, to two devices 23 , 24 displays. Microcomputer 32 works with data in digital form encoded with zeros and ones taken in the outputs of BS 31. MK 32 includes an access control unit (ECU) 35, which, in turn, may include a control unit for display devices ( BUUO) 36 and the access control unit of the computing system (BUDVS) 37, and both of these blocks are associated with two input devices. It should be noted that the creation of the BUD 35, the BUUO 36 and the BUDVS 37 can be implemented both in hardware and software, and the term access control unit is known from the following source: English-Russian Dictionary of Computer Engineering / Edited by E.K. . Maslovsky. - M .: Rus. Yaz., 1990, p. 688. The plates 29 are connected to the output of the generator 30, and each of the plates 28 is connected to the corresponding input of the voltage comparator included in the BS 31. In addition, LEDs 20 and a wireless adapter (ABC ₁ ) 38 are connected to the output of MK 32 designed to wirelessly connect the MK 32 to other UIPS elements, for example, to the frequency converter 4. Naturally, in addition to the ABC ₁ 38, you can also use the direct connection of the MK 32 to the frequency converter 4. The wireless adapter 38 includes a transceiver associated with the MK output 32 through a digital modulator, but with input MK house 32 - through the timing unit. The latter is intended to restore - • Kl Kl Kl уj UI

digital data that are present at the input of the transceiver operating in the receive mode. It can be noted that as a transceiver it is possible to use a standard device operating in BIutooth 1.1 standard, for example, a device of type D - Link DBT - 900AP. The power supply of the generator 30, MK 32 and BS 31 is carried out from its own power source (ISP) 39. For the normal functioning of the ESD, the lower part 40 of the chess pieces must be conductive. The operation of ESD is as follows. In the initial state, MK 32 remembers the initial arrangement of chess pieces. After each movement of the piece, discrete signals occur at the output of the corresponding comparator, according to which MK 32 determines its new position on IP 9. Thus, in this UIPS, the computing system is connected to the means for obtaining data on the location of the chess pieces 12, 13, 14, 15, 16, 17 on IP 9, made in the form of ESD. If there are enable signals at the output of the BUUO 36, then after each change in the position of the figure on IP 9, either two light-emitting diodes (LEDs) 20 are ignited, one of which is located next to field 18, and the other with field 19, or the corresponding indication on UO 23, 24. The formation of a discrete signal at the output of the comparator is due to a change in its input of an alternating voltage after moving a chess piece. With each movement of the figure there is a change in the value of the capacitance between the plates 28, 29, and therefore a change in the value of a part of the alternating voltage removed from the output of the generator 30 present at the input of the corresponding comparator. In this case, the operating voltage of the comparators BS 31 is selected in such a way that in the case of a figure appearing at the output of the corresponding comparator, a discrete signal appears corresponding to a logical unit. The change in the value of the capacitance C _N between the plates 28, 29 in the presence of a chess piece is due to the additional connection of two series-connected CF ¹ and CF ² tanks in parallel to CN, where Cp ¹ is the tank, the plates of which are the plate 28 and the lower part 40, and CF ² - capacity, the lining of which is the plate 28 and the lower part 40 of the chess piece. To conclude the description of this UIPSH scheme, we note that it can also include one or several auxiliary computers (BK) 41, each of which is connected to a means for obtaining data about the location of chess pieces on the playing field and to the access control unit 35. 2 shown in FIG. In the UIPSH, the connection of BK 41 to the SPD on the arrangement of chess pieces was carried out using MK 32.

In Fig.3 shows a diagram of the inverter 4 included in the UIPSH. This circuit includes a time counter (BOW) 42 connected to a display 43, which has two indicators - IND 5 and IND 6, and to the control unit (CU) 44. The latter contains open (in the initial position) contacts 45, 46, associated with the buttons 7, 8. By closing the contacts 47, the operation parameters of the inverter 4 are set, for example, the control time value To is set. The BOV 42 includes two counters for accumulating game time, connected to a common pulse generator, the frequency of which is set by the quartz resonator 48. It should be noted that clock microprocessors (CMC) of the SMC 5980 type manufactured by the company can be used as BOV 42 Seiko Yersop ". The BOV 42 operation algorithm in this case is entered into the memory of the Chelyabinsk Metallurgical Plant during its manufacture. Of the other elements of the circuit, we note LED 49 and LED 50. The first of them is designed to indicate the inclusion of IND 5, and the second is to indicate the inclusion of IND 6. The power supply is produced from the battery 51 connected to the BOW 42 through switch 52. In addition, as will shown below, in some UIPSH variants, a chess clock must be associated with a VU. For this purpose, the input-output (I / O) device included in the BOW 42 can be connected via bus 53 to the wireless adapter (ABC ₂ ) 54, which is consistent in its parameters with ABC ₁ 38. Thus, the BOW 42 and MK 32 are interconnected by means of the wireless communication channel (BSC) indicated in FIG. 3 as a broken arrow 55, i.e. The BUD 35 is connected with the VU, which, in turn, is connected through KBS and BOV 42 to the VU 44 of the chess clock. Thus, the UU 44 of the chess clock is connected to the ECU 35. The last connection, as will be shown below, was made in order to use the buttons 7, 8 as a control unit. In the presence of BK 41, the chess clock counting unit 42 is connected to it via MK 32.

Figure 4 presents the UIPS, in which the above-described ESD 27 is used, and the VU is made in the form of one BK 41 and two external chess computers (HK): 11IK ₁ 56, IHK ₂ 57. Each of these HK contains UO and HC, made in type of keyboard. Chess computers 56, 57 are connected, firstly, to MK 32, which in this version UIPSh only functions BUD 35, and secondly, to BOW 42 chess hours. The auxiliary computer 41 is made in the form of a remote computer (CC) connected to the ECU 35 through the worldwide computer network Inter no (VKSI) 58. The result of the work of BK 41 may be reflected in any of the MA included in the HK. The connection of this or that U O to BK 41 is made by applying to the ECU 35 a signal from the corresponding HK (the signal itself is formed after the player interacts with the HK keyboard). At the same time, the result of the work on calculating the next chess move in this HK or in BK 41 begins to be displayed on his OO. Note that the ECU 35 can be connected to the BOW 42, 11IK ₁ 56, ShK ₂ 57 through internal wireless adapters of the type D - Link DW L - G520, operating at frequencies from 2.4 GHz to 2.483 GHz and having an external antenna. IUK ₁ 56 and IHK ₂ 57 chess computers can be connected to external wireless adapters such as Eline ELW - 9610SXg - Wireless LAN Вroаdbаd router 961 OSX - g 57 M, which have external antennas.

Figure 5 presents the appearance (top view) of the UIPS, in which the VU, BUD, BUDVS and BUUO are implemented as one BK 41 and two personal computers (PCs). The first personal computer (PC) includes the following tools: UO, made in the form of a liquid crystal display (LCD) 59; HC, made in the form of a two-button wireless manipulator 60 type "mouse"; system unit (SB) 61. The second personal computer (IZhz) includes the following tools: U O, made in the form of an LCD 62; HC, made in the form of a two-button wireless manipulator 63 type "mouse"; SB 64. Means 59, 60, 62, 63, as well as ШЧ 4, are located on the chess table 65, under which, in turn, are BK 41, which has its own MA, HC, and system units 61, 64. The latter are connected with ESD 27, in the upper part of which IP 9 is applied. Inside BK 41 and SB 61, 64 software blocks BUD 35, BUUO 36, BUDVS 37 were created, while instead of two SBs, the computing system can include only one SB connected to two U V 60, 63, as well as two U O 59, 62. Electronic chessboard 27 of the DGT type electronic chess board of the company "DGT projects" has sensors by which information about chess moves through a USB cable 66, a USB cable 67 and a USB cable 68 respectively to BK 41, SB 61, SB 64. DGT XL type 4 electronic chess clocks are connected to EShD 27 using a USB cable 69. In addition Moreover, the chess clock 4 is connected to SB 61, SB 64 and BK 41. It should be noted that BK 41 may not have its own O O and HC. In this case, when using standard pairing devices, the indication of its operation is reflected on the LCD 59 or on the LCD 62, and the manipulator 60 or the manipulator 63 is used as the HC. Block 35 the access control system contains three BUUO 36 and three BUDVS 37, moreover, in each facility BK 41, SB 61, SB 64, one BUDVS and one BUUO are formed. Each of these units is associated with wireless manipulators 60, 63 having identification numbers Z ₁ and Z ₂ . The algorithm of operation of the BUDVS and BUUO in this case will be as follows. After pressing the button of the manipulator 60 (the positions indicated in parentheses refer to the actions after pressing the button of the manipulator 63) with the number Z ₁ (Z ₂ ) at the output of the control unit, which is included in SB 61 (SB 64), an LCD command 59 is formed ( LCD 62) for the purpose of indicating on it chess moves calculated in SB 61 (SB 64); at the output of the BUUO, which is part of BK 41, a command is issued to turn on the LCD 62 (LCD 59) (if BK 41 does not have its own U О) to indicate chess moves calculated on BK 41 on it; at the output of the BUDVS included in SB 61 (SB 64), a blocking command of the manipulator 60 (63) is generated, i.e. any influence of the player on this manipulator does not affect the functioning of the program for calculating the chess move in SB 61 (SB 64); at the output of the BUDVS, which is part of BK 41, a command to unlock the manipulator 63 (60) is generated (if BK 41 does not have its own HC), i.e. by means of this manipulator, the player can adjust the operation of the chess program running on BK 41. In the absence of BK 41, the operation algorithm of this UIPS will be as follows. After pressing the button of the manipulator 60 (63) with the number Z ₁ (Z ₂ ) at the output of the BUUO included in SB 61 (SB 64), an LCD 59 (LCD 62) turn-on command is generated to indicate the chess moves calculated in SB 61 (SB 64); at the output of the BUUO, which is part of SB 64 (SB 61), a command is issued to turn on the LCD 62 (LCD 59) to indicate chess moves calculated on SB 64 on it; at the output of the BUDVS included in SB 61 (SB 64), a command to block the manipulator 60 (63) is generated; at the output of the BUDVS, which is part of SB 64 (SB 61), an unlock command for the manipulator 63 (60) is generated; time for IND 6 (IND 5) increases.

Figure 6 presents the UIPSH, in which the following service computers (OBK) are used as IP and BCH: 06K ₁ 70, 06K ₂ 71. Each of these OBKs contains a virtual game field formation unit (VIP), a virtual chess piece set formation unit (SHF), a virtual chess clock formation unit (VHF) and a virtual display device (VUO) formation unit. By means of these units on each serving display computer (DOBK) 72 is formed, firstly, a set of chess tools in the form of VIP 73 with the HFS and HFS 74 placed on it, and, secondly, a virtual display device (HLS) 75. The computing device in this UPSH consists of IHK ₁ 56 and ShK ₂ 57, and the ECU is made in the form of a control computer (UPK) 76. The input device of this UIPS are keyboards of serving computers (KOBK) 77, 78, which are also connected with 11IK ₁ 56 and 11IK ₂ 57. For the purpose of exchanging OBK data 70, OBK 71, 11IK ₁ 56, ShK ₂ 57 and UPK 76 are connected by a network channel, made, for example, in the form of an Ethernet network or in form of a wireless LAN. In the first case, ObK 70, ObK 71, 11IK ₁ 56, UJK ₂ 57, and UpK 76 can be connected using adapters, T-shaped connectors, and a hub 79. It should be noted that this local network can be a computer network concentrated in one a building owned by the International Chess Federation (FIDE). If the Global Internet Internet (GSM) 80 (Fig. 7) is used to combine ObK 70, ObK 71, 11IK ₁ 56, HIK ₂ 57, and UpK 76, then their actual position can be located almost anywhere in the world.

On Fig depicts a portable device (PU) 81 for playing advanced chess, associated with the WU, made in the form of one or more universal computers (UNK) 82, through a wireless channel 83, which includes a removable external dipole antenna 84, connected with a multi-channel adapter ABSi 36, and an antenna 85 connected to the UnK 82 through an adapter ABC ₃ 86. In addition to the removable external dipole antenna 84, the PU 81 also has an internal antenna, shown in Fig.2. The portable device 81 for playing advanced chess is intended for amateur chess players, as well as for secondary schools, as an effective means of teaching a chess game and increasing the intellectual level of students. The presented design contains ESD, ШЧ 4, having IND 5 and IND 6, as well as LED 49, 50. The main difference between PU 81 and the devices shown in Fig. 1 and Fig. 4 is that ESD, ШЧ 4, ИП 9 , MK 32 and ABC ₁ 36 are structurally combined in one case. Another difference between PU 81 is the presence of an additional row of SVD 20 located instead of field 18. As noted, the main objective of the present invention is to provide such a method and apparatus for playing advanced chess in which the outcome of the game depends primarily on the level human games and does not depend on the computing power of WU.

The operation of the device for playing advanced chess is carried out in accordance with vii with the scheme of the algorithm shown in Fig.9. The practical implementation of this algorithm is carried out using special and standard software that is stored in read-only memory devices of the following means: 1, 4, 32, 41, 42, 56, 57, 61, 64, 70, 71, 76, 81, 82. The UIPSH work begins after the execution of step 87 (ster 87), which is associated with operations such as: loading chess analytical programs and chess game programs into the control room; switching on of frequency range 4; installation of blocking access to devices UO 20, 23, 24, 59, 62; VUO 75; UO, which are part of ShK 56, 57, BK 41; HC 21, 22, 33, 34, 60, 63, 77, 78; HC, which are part of the CC 56, 57, BK 41. The above blocking of access to the MA and the HC is provided by the ECU 35, the ACU 36 and the ACU 37. Before starting a chess game, these players block access to the computing system. A Chess Analytical Program (ShAP), for example, Shredder 9 UCI, Jupior 9, or Niars 9, is used to analyze a player’s current chess position in order to find him the next move. Chess game program (SHIP), for example, such as "Hydra", "Fish", "Fritz 8", can also be used to analyze chess positions. Using SHAP and SHIP increases the player’s strength, since each chess player becomes an “Advagent Chess-Рlauer” (a chess player with an advantage) or abbreviated ACP, and among speakers in chess competitions there will always be such an ACP with a high level (the highest level ) or abbreviated as HL ACP, the power of the game of which in real time scales exceeds the level of the game of the world champion and any level of the game of a chess computer that is arbitrarily powerful at a given moment in time. To prove this statement, we can assume that with absolute probability HL ACP, which has the highest level of chess in the world, is the world chess champion, as an assistant to which, or, most of all, an intellectual amplifier, the most powerful ShAP instant of time, implemented on the fastest computer. Obviously, the above HL ACP exceeds the level of the world champion’s game, since assuming that the world champion is playing with his double equipped with an intelligent amplifier, the advantage of the latter does not raise any doubt, if only because of the ability to use a computer when implementing technical endings, where the advantage of the latter over man is universally recognized. This is due to the fact that the ShAP in each position of the technical end instantly gives an estimate (on a binary scale), which The paradise for three, four and five-figure endings is true, since for such endings digitized arrays are developed, called table bases and containing a complete set of combinations in the arrangement of several figures. Under real conditions, an ACP ₅ having a high-level may not be a world champion, but a world champion, in turn, may be an HL ACP, relying not on the best chess program. On the other hand, the world champion, relying on the same intellectual amplifier, will easily beat him even if this chess computer can win the world champion in a personal meeting. Indeed, a chess program is, in the end, a task whose solution is carried out by enumerating various options. But in exhaustive tasks, where in each situation the number of possibilities is much greater than the number of moves in a chess position, the practical value of a complete search for a fixed depth is very low. Using different methods of cutting off the number of searches, for example, the method of faces and estimates, cannot give an exact solution in the form of the best move in a given position, since the process of cutting off options requires constant calculation of evaluation functions that map each position to its estimate as either a real number or any function that takes into account some features of this position. But it is practically impossible to adequately reflect valuation functions with a position having high entropy, since it is obvious that the assessment of this position is connected, first of all, with the game plan, which often ends in positions that are outside the bounds of the graph formed by the computer program. By limiting the search tree in TPATT to those options that are most acceptable from the point of view of implementing one plan or another, the chess player significantly enhances any chess game program, of which SHAP is one of the components. However, it should be noted that in this invention only game chess programs can be used, since the latter can be enhanced by increasing its working time (increasing the depth of calculation of the chess move) or by connecting a more powerful computer. Now, using the example of a practical game algorithm shown in Fig. 9, we first consider a special case of playing advanced chess. If during the game the countdown of time T ₁ for IND 5 or the countdown of T ₂ for IND 6 (action 88) is not completed (“No” in condition 89), i.e. Ti <T ₀ ¹ (That ¹ is the control time set on IND 5 for the first player) or T ₂ <That (That is the control time set for the VI), and there was no predetermined number N (N = 0, 1, 2, ...) of moves ("No" in condition 90), then the next fifth move (n <N) without using the player PI 2 or VI 3 computing device. It is also impossible to use VU in the event that after making N moves there was already a simultaneous unlocking of the UO, VUO or simultaneous unlocking of the following means: UO, VUO, one of the hydrocarbons ("Yes" in condition 91). In both cases, attempts to use the WU will be excluded due to the presence of the corresponding signals at the output of the WUUO and BUDVS, incoming or associated with the WU. The result of UO locks can be reduced either to the absence of the whole image on them or to the absence of only information about the next chess move calculated (the calculation of the move can be carried out immediately after the start of the game, i.e. after the start of action 88) in one of the following means: IJUK ₁ 56, ШK ₂ 57, BK 41, MK 32, СБ 61, СБ 64, ПУ 81, УнК 82. At T ₀ ¹ > T _b T ₀ ² > T ₂ (“No” in condition 89), n> N ( “Yes” in condition 90) and if there is no unlocking during a chess game (“No” in condition 91), each player PI 2, VI 3 must analyze before making another chess move the current chess position and, if it is technical in the player’s opinion, this player can transfer (“Yes” in condition 92) its completion (act 93, act 94, act 95) of the VU, which includes one of the following means: MK 32, ШК 56, 57, СБ 61, 64, ПУ 81, УнК 82. Here, by technical position we mean a position that should end (“Yes” in condition 96, step 98) with a result (draw or win) that suits this player. After one of the players transfers the playing chess position to the current chess position, the other player automatically becomes ACP, i.e. another player gains the right to use one of the above tools included in the control unit as an “intelligent amplifier”. Moreover, this player, for any computing power of his opponent’s computer, for example, ShK 56, will always have, as will be shown below, a game advantage even without using special analytical chess programs for this. Then it is obvious that if the analysis, for example, by the first player of the current chess position as technical turned out to be erroneous, the second player gets the opportunity to bring the chess game to win (if the first player rated the current position as a draw) or to a tie (if the first player has the current position rated as winning) further without using HC and analytical programs. The fact is that the advantage in the completion of technical positions can be achieved, as will be shown below, either by a simple increase in the time given to the WU associated in this case with the second player, or by arranging for the second player to access the more powerful BK 41. In another embodiment, the advantage in completing the technical positions can be achieved to make it possible by increasing the computing power by simply connecting any BK 41, for example, to the corresponding HK. Post-replay is transmitted by entering PI 2 or VI 3 unlock command ("Yes" in condition 92) of all U O (if BK 41 has a separate U O) or AUO and one of the HC. The input of the unlock command is, in turn, by the interaction of PI 2 or VI 3, respectively, with one of the following means: button 21 or button 22; wireless manipulator 60 or 63 of the type of mouse; COBK 77, 78; other input devices DIK ₁ 56, ShK ₂ 57, SB 61, SB 64 and UnK 82. As other HCs in these means, any known devices intended for this purpose (light pen, voice input means, etc.) can be used. Here, it can be noted that in the initial state all HCs are blocked only for those operations that are related to the interaction of players and WUs operating in the game and analytical chess programs functioning mode, but are not blocked to enable this mode. The implementation (step 93) of the unlock command of the MA, the VUO is carried out by the BUUO, and the implementation (step 94) of the unlock command of one of the HC is carried out by the BUDVS. If there is an auxiliary computer 41 in the UIPSH, the implementation of step 93 is accompanied by the additional connection of one of UO's to it. If BK 41 has its own UO, the implementation of step 93 is simply expressed in its connection. The simultaneous unlocking of the MA, VUO and one of the hydrocarbons can be performed on a predetermined number of chess moves, which, in turn, can be displayed on indicators 23, 24, 25, 26, 59, 62, 75. Note the specifics of performing step 93 and actions 94 on the example of UIPSH 1, presented in Fig.l. In its initial state, O О 23, 24 displays one of the following words: "not turned on", "no access", "press the button to turn it on." These words are formed in MK 32. All HC made in the form of buttons 21 and 22 work only in the unlock enable mode of O O and one of the HC. After this mode is activated by button 21 (22), operating, for example, within only one stroke, the display device 23 created in MK 32 is displayed howling chess program the next move. After its implementation on IP 9 (action 95), the display device 20 or 24 (23) displays the next move formed in MK 32 by the analytical chess program, as well as an assessment of this move. The cessation of the ACP formation of the next move (and its evaluation), which, after the lapse of time, can change to a stronger one, is performed by pressing the button 22 (21) once or twice. If the button 21 (22) is pressed during the action of the unlock mode, no reaction to this action will be followed by MK 32. In some versions of the implementation of the described algorithm, after simultaneously unlocking the UO, VUO and one of the hydrocarbons, it is necessary to form (step 97) a command for adjusting the frequency of the accumulated time T ₁ or time T ₂ (for example, decreasing it, or increasing it when counting down the time for IND 5, 6) to the player who gains access to the HC of the computing system after the above unlock. After expiration DISs 5 reference time T ₀ or ¹ to 6 IND reference time T ₀ ² ( "Yes" in INSTALLS lovii 89), the game ends (step 98). The need to use a variant of the game of advanced chess, in which action 97 is carried out, may arise in the absence of BK 41 and if the level of the WU game is higher than the players 2, 3. The fact is that all the ShAP and chess game programs are arranged in such a way that in real of time, they gradually refine the assessment of the current situation at IP 9. In other words, increasing the time to select the next move is beneficial to the WU, since it reaches a new level of calculation, as a result of which the search depth increases by several moves. Thus, even if the players PI 2, VI 3 play worse than VU, none of them will be able to take advantage of this circumstance, since the “transfer” of completing (with sufficient time on the corresponding IND) of the chess game to the computing device can be carried out only in such technical positions, which in most cases cannot be played by a weaker computer. The latter include, in particular, the positions for which digitized arrays have been developed, containing a complete set of combinations in the arrangement of several figures. These are the so-called "table bases". Thus, a chess player, using the UIPPI described in this invention, can check chess “novelties” even in those games that are held under the conditions of a shortened time limit. It can be seen from the foregoing that a special case of playing advanced chess differs primarily in that it prescribes certain the number of chess moves, after which during the game it is possible to unlock the display devices and one of the input devices. In addition, the latter can be unblocked only once during a batch. In the general case, the functioning of the game algorithm depicted in Fig. 9 can occur without the presence of one or two actions in it: actions 89 and actions 90. In other words, the goal of connecting a WU with one of the players can consist not only in playing out the technical position, but also in preparation by a computing system for repeating on IP 9 by this player only one or several next moves. It can be seen from the presented algorithm that in this case the second player becomes ACP only for the time of thinking about the return move (moves). Also, this player, in accordance with step 97, which describes the adjustment of the operating time of the VU, in particular, by reducing the accumulated time T ₁ and T ₂ , can receive a more accurate estimate of the proposed VU retaliatory move without any personal intervention of one of the players in its work. Thus, in the general case of the advanced chess functioning algorithm, the game level of the PI 2 and VI 3 players can be less than the game level of the computing system. In this case, the player who is better versed in the positional game and the endgame wins, since the transfer to VU of the right to make the next move (next moves) can only be in a position that is not critical for the subsequent game. In FIG. Figure 10 shows the algorithm for the operation of the UIPS without a separate HC. As the latter, UU 44 is used, which is connected to the access control unit 35. With this solution, the UIPSH, shown, for example, in Fig. 5, can be performed without manipulators 60, 63, and in Fig. 8 without buttons 21, 22. The start of the functioning of the algorithm is connected with the start of a chess clock (action 99), which can be turned on both before the game and during the game, for example, after an unexpected stop. If in the process of counting the time T ₁ (action 100) or time T ₂ (action 101) a move was made (“Yes” in condition 102), then after one click on the button ШЧ 4 (“Yes” in condition 103) and checking it to comply with the rules of the game (condition 104), either an in-band switching is performed (action 105) or a blocking (“No” in condition 104) of such a switching. If the course is incorrect, the signal is removed from the output of the ESD 27, which, upon receipt of the inverter input, blocks the operation of the UU 44, i.e. after clicking on any of the buttons 7, 8, the readings of the frequency converter, as well as their operation mode, do not change. If after the move was made z (z = 2, 3 ...) clicks on button, then after at least a second press (“Yes” in condition 106), predefined actions 107, 108, 109, similar to those described in the previous algorithm, occur. By means of action 107, a command for correcting the readings of the HF is formed on the indicator of the player who has not performed z presses of the HF button. Through action 108, two UOs are unlocked and the HCs are unblocked for the player who did not z press the NW button. At the same time, an auxiliary computer 41 is connected to this HC (in the presence of BK 41). Through action 109, a move is displayed, indicated by the UO of the player who made z clicks on the HF button. If there was no move (“No” in condition 102), then the actions 107, 108, 109 take place immediately after the second or more clicks on the corresponding button of the BC 4. In conclusion of the description of this algorithm, we note that checking the course for the correctness of its implementation (condition 104) after the implementation of step 109, it is performed by comparing, for example, in the control unit, the progress indicated by the O O after it has been calculated in the appropriate means of the control unit and the move made by the player on the ESD 27. When they do not coincide, the control unit generates a lock command 44 of the control unit. Now we give specific examples illustrating the operation of the UIPS.

Example 1. Suppose that the game of advanced chess is played using the UIPSH shown in Fig. 5, but without BK 41. Moreover, the white pieces 10 are played by PI 2, the black pieces 11 are played by VI 3, and the control time is T = T ₀ = 10 The min set for both players on the 4-channel through contacts 44 is 10 minutes. In addition, during the entire batch, only one unlocking is possible (step 93, step 94), and the set value of N is zero (N = 0), i.e. immediately after the start of the game, it is possible to simultaneously unlock two UOs made in the form of LCD 59, LCD 62 and one of the HC made in the form of manipulators 60, 63. Before starting the game in HK ₁ (SB 61), the first player 2 was installed (installed) the game and at the same time analytical program Chess Tigger 2004 (rating 2721), and in PK ₂ (SB 64), the second player 3 delivered two programs, one of which was a game (Zarra 2.0 b program), and the second - analytical (Нірсs 6.0 Master program ), moreover, the composition of the analytical program Hiars 6.0 Masters input It is the subroutine of issuing on the LCD 62 of the top three branches of analysis with various first moves. So, after turning on ШЧ 4 (action 87), the first 14 moves or, which is the same, the first 27 actions 95 were carried out by PI 2 and VI 3 without the use of VU (in parentheses after the designation of the move made the time T ₁ or T ₂ , accumulated PI 2 or VI 3 during the game: I. e4 e5 2.f4 Кfб 3. Cc4 К: e4 4. КfЗ d5 5. КfЗ Cc5 6. Фe2 Cg4 7. dЗ Кeb 8. C: d5 Ф: d5 9. dе Фdб 10. фе C: £ 3 11. gf Ф : e5 12. сЗ 0 - 0 - 0 13. СеЗ C: eЗ (T ₂ = 7 min 16 sec, while due to the countdown of the time for 4 part 4 the time display on IND 6 is T ₀ ² - T ₂ = 2 min 44 sec) 14. Ф: еЗ (T ₁ = 5 min 35 sec, the time display on IND 5 is T ₀ ¹ -T ₁ = 4 min 25 sec) .In addition, each of these moves comes from the ES output D simultaneously in SB 61 and SB 64. After the 14th move of the first player, VI 3, assuming that the position is technical (winning), presses the corresponding button on the manipulator 63, thereby unlocking the LCD 59, LCD 62 (action 93), as well as the manipulator 60 (action 94) .After that, the LCD formed by the Zarra 2.0 b game program in SB 64 of the 14th move is displayed on LCD 62: 14. ... ФЬ5 (T ₂ = 8 min 02 sec), which, in turn, the second player 3 carries out on IP 9 (action 95). Using, through interaction with the manipulator 60, the analytical capabilities of SB 61, as well as the AChss of Chess Tigger 2004, the first player 2 chooses the move 15. Фe2 (T ₁ = 5 min 34 sec), which reproduces on PI 9. In accordance with step 97, the value of T ₁ decreased due to an automatic reduction of the time T ₁ by 30 seconds (the time the first player selected the 15th move was 29 seconds) at the moment VI 3 pressed the manipulator key 63. Moreover, this decrease (when counting down the time, the IND readings increase) was caused the corresponding signal generated in SB 61, 64 and ne input to BOV 42 ШЧ 4. After Zarra 2.0 b was selected in PK ₂ (SB 64) by the response program 15. ... Фbб, which the second player 3 repeated on IP 9, PI 2 passed the game (action 98), because he could not even use the ACP and ШQ find options to continue the game with a different result.

Example 2. Assume that the game of advanced chess is played using UIPSH, depicted in figure 4. Moreover, PI 2 plays with white pieces, VI 3 plays with black pieces, and the control time T ₀ = T ₀ = T ₀ set for both players on BH 4 equals 2 hours (T ₀ = 2 hours). As in the first example, only one unlock is possible during the entire batch, and the set value of N is zero (N = 0). Before the start of the game, the following two gaming and analytical chess programs were put in BK 41: Deer Fritz 10 and Rubka 2.3. In each of the chess computers 11IK ₁ 56, IHK ₂ 57, the game chess program "Deer Shredder 10" was installed. Immediately after the start of the clock

4 (step 88) PI 2 presses the corresponding button on the keyboard 11IK ₁ 56, thereby unlocking its UO and UO of the chess computer 57 (step 93). At the same time, U O and U B of the chess computer 57 are connected to BK 41 (actions 93, 94).

All even moves were received by VI 3 after interacting with BK 41 using the IPK ₂ 57 keyboard. Example 3. Assume that the game of advanced chess is played without BK 41 using UIPSH 1 shown in Fig. 1 and Fig. 2, with PI 2 playing with white pieces 10 and VI 3 playing with black pieces 11. In addition, repeated unlocking for a given number of moves p is possible during the game (actions 93 , 94), and the set value N = 10, i.e. immediately after the 10th move, it is possible to simultaneously unlock two U 23, 24 and one of the two hydrocarbons, made in the form of buttons 21, 22. The principle of adjusting the time for the inverter 4 is to automatically add the time t on the corresponding indicator of the inverter 4 after the action 93 and 94. The value t of the added time after each move is determined by the following formula: t = 2 x T _t , where T _t is the time of one move committed with the help of WU. Before the start of the game, the game-analytical program "Fritz 8" was recorded in MK 32 memory. The first 12 moves were made by PI 2 and VI 3 without using MK 32: 1. e4 c5 2. dЗ Кеб 3. gЗ d5 4. Kd2 gб 5. Cg2 еб 6. KgB Cg7 7. 0-0 Kge7 8. Лel b6 9 .KΩ a5 10.e5 Фc7 11.Cf4 hb 12.h4 Cb7. After this move, player PI 2 determined that the current position is technical (winning) and by five times pressing button 21, he transferred the control unit to MK 32 formation mode for the next five moves. At the same time, the number "5" was displayed on display 25, which after each move made decreased by one: 13. sz 0-0-0 14. d4 cd 15. cd Sub 16. Lsl Kb7 17. Lez Fd7. Due to lack of time, each of The player of VI 3 simply read back moves from the display 24 and duplicated them on IP 9. Once again, we note that the quality of these moves due to the longer calculation time (and hence the depth) in MK 32 exceeds the quality of the moves made by PI 2. The exception was The 14th move, which VI 3 made on IP 9 after two additional presses of the button 22. Note some features of the operation of this UIPSH 1 after performing steps 93, 94. In the initial position, the progress indication is made after calculating in MK 32 taking into account the added extra time , and after each pressed Pressing button 21 or 22 resumes the calculation of the course until the button is pressed again. So, after the 17th move, “О” was displayed on display 25, which means the WU returned to the access blocking mode for UO 23, 24 and HC 21, 22. But since the position remained technical PI 2, again pressed the button 21, having realized the second unlocking of UO 23, 24 and HC. As a result of this, the game was completed as follows: 18.

The invention can be applied in competitions of chess players - professionals in advanced chess. Especially great effect can be obtained in rapid chess competitions, since in this case the quality of games sharply increases, approaching in level to the game with the usual seven-hour control. The invention can be used in the industry, specializing in the production of computer chess. The use of the invention may consist in organizing the mass production of portable advanced chess, shown in Fig.8. The invention can be used as a learning tool, instead of the usual chess, which the organization for education, science and culture of UNESCO recommended to introduce in schools around the world. The use of advanced chess as a learning tool, due to the possibility of adapting to any level of the child’s initial intelligence, as well as to his learning abilities, due to the presence of choice and a whole range of factors, the appropriate selection of which can establish such a level of complexity of a chess game, which corresponds to the level of preparation of the child and his interest in playing chess. The invention can be used to create artificial intelligence. This is due to the presence in the chess game of two components - formalized and unformalized. Formalized May, a component of human activity is carried out according to certain rules. The non-formalizable component is associated with the application of any rules unknown to science. Thinking, intuition, common sense are not specific concepts, but nonetheless involved in the mental activity of man. Advanced chess, in comparison with computer chess (game chess programs), does not exclude the non-formalized component from the decision-making process about the next move and therefore is a more objective indicator of the level of game of computer chess (game chess programs). Indeed, a successful game of a chess computer against ACP may be to the extent that a chess computer has mastered the art of synthesizing new chess ideas, which is a sign of artificial intelligence. The game of a person against a computer is a biased indicator of the real level of play of computer programs due to the mismatch of the time constants of the formalized components in the decision-making process of a person and a chess program. Thus, the true strength of chess programs can only be determined in the game of advanced chess.
