The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's king; checkmate occurs when a king is ...
Check (chess) Black 's king is in check by the white rook. In chess and similar games, check is a condition that occurs when a player's king is under threat of capture on the opponent's next turn. A king so threatened is said to be in check. A player must get out of check if possible by moving the king to an unattacked square, interposing a ...
White can achieve a checkmate similar to fool's mate. When the roles are reversed, however, White requires an extra third turn or half-move, known in computer chess as a ply. In both cases, the principle is the same: a player advances their f- and g-pawns such that the opponent's queen can mate along the unblocked diagonal.
Time trouble. In chess played with a time control, time trouble, time pressure, or its German translation Zeitnot, is the situation where a player has little time to complete the required moves. When forced to play quickly, the probability of making blunders is increased, so handling the clock is an important aspect of chess playing.
Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with capture) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured—the player loses as soon as the player's king is checkmated.
Perpetual check. In the game of chess, perpetual check is a situation in which one player can play an unending series of checks, from which the defending player cannot escape. This typically arises when the player who is checking feels their position in the game is inferior, they cannot deliver checkmate, and wish to force a draw.
Handicaps (or "odds") in chess are handicapping variants which enable a weaker player to have a chance of winning against a stronger one. There are a variety of such handicaps, such as material odds (the stronger player surrenders a certain piece or pieces), extra moves (the weaker player has an agreed number of moves at the beginning of the game), extra time on the chess clock, and special ...
If a player's time runs out before the game is completed, the game is automatically lost (provided the opponent has enough pieces left to deliver checkmate). [2] The duration of a game ranges from long (or "classical") games, which can take up to seven hours (even longer if adjournments are permitted), to bullet chess (under 3 minutes per ...
