![]() It is not the same for the pieces of the opponent. The piece blocks that square for its own pieces as long as it stays there. There can be only one piece in each square. There is an obligation for the players to make a move when their turn comes. ![]() Move of two players with one of the chess pieces consequently is called move. White starts to the game and players make one move with one piece every time. Queen, stays in the square of the color given to the each player. The order of the figures are from left to right for white (it is the opposite for the black) and are ordered as follows: Rook, Knight, bishop, queen, king, bishop, Knight and rook. Pawns are placed to the line before the last line. Light Pieces: Two horses and two knights and two BishopsĬhess board is put between the players with its white corner square is placed to the right of the player according to the perspective of the players. 16 of them are white (or light color), 16 of them are black (or dark color). In the beggining of the game there are 32 pieces. The captured piece cannot return to the game, but the pawn which has reached to the last square of its line, whether being outside the game or not, can be changed with another piece that is more valuable than pawn and less valuable than king. Every piece has the power to disqualify every piece it has dislocated by getting located in the square where the piece of the opponent stays. It is essential in the game to limit the opponents ability to move and weaken the opponent by taking its pieces by moving one’s pieces to adventageous squares. Also the game can end in any moment with one of the players’ acceptance of defeat or with offer of a duece by a player and by acceptance of the other player. If the king of a player is in a square that is not under the threat and only the king of this player is left and no other square is left without being under threat that the player can make a move than the game finishes with pat, meaning deuce. This enables more chess pieces to move to the center. Most important step taken to show fast progress is gambit, meaning sacrifice of a pawn. ![]() This abides with the principle of weakining the opponent by taking its man.įast progress is important for chess. This means that the square of which the opponents’ king is in is under threat and that there is no move left which enables the escape to another square that is not under threat or to avoid the threat. The yellow blocks are special cases.The goal of the chess is to mat the king of the opponent. The bottom-left top-right diagonals are much more complex.) (Make sure you see both sets of diagonals as top-left to bottom-right. The "secondary" green diagonals (same orientation as red).The "primary" red diagonals (they run top-left to bottom-right, like a backslash).The incrementing blue vertical groups of 4.The bottom-left block is the starting position and the numbers in the blocks represent the minimum number of moves to reach those blocks. ![]() In the diagram below, the number in the square is the minimum number of moves needed to reach that square (you can use breadth-first search to find this):īecause the solution is symmetrical across the axes and the diagonals, I've only drawn the x >= 0 and y >= x case. The key to finding this is to notice the patterns that emerge when you draw the board. ![]() Here's a correct O(1) solution, but for the case where the knight moves like a chess knight only, and on an infinite chess board: ![]()
