If it is the player's piece that was touched, it must be moved if the piece has a legal move.
In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times during the game. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position. [ 1] Two positions are by definition "the same" if the same types of pieces occupy the same squares, the ...

Solving chess consists of finding an optimal strategy for the game of chess; that is, one by which one of the players ( White or Black) can always force a victory, or either can force a draw (see solved game ). It is also related to more generally solving chess-like games (i.e. combinatorial games of perfect information) such as Capablanca ...
The problem may be solved using simple addition. With 64 squares on a chessboard, if the number of grains doubles on successive squares, then the sum of grains on all 64 squares is: 1 + 2 + 4 + 8 + ... and so forth for the 64 squares. The total number of grains can be shown to be 2 64 −1 or 18,446,744,073,709,551,615 (eighteen quintillion ...
Zwischenzug. The zwischenzug ( German: pronounced [ˈtsvɪʃənˌtsuːk], "intermediate move"; also called an in-between move) is a chess tactic in which a player, instead of playing the expected move (commonly a recapture ), first interposes another move posing an immediate threat that the opponent must answer, and only then plays the expected ...
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last rank. The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same color. [ 1] The new piece does not have to be a previously captured piece. [ 2] Promotion is mandatory when moving to the last rank; the pawn cannot ...
Pawn (chess) The pawn (♙, ♟) is the most numerous and weakest piece in the game of chess. It may move one square directly forward, it may move two squares directly forward on its first move, and it may capture one square diagonally forward. Each player begins a game with eight pawns, one on each square of their second rank.
