A stalemate is an automatic draw, as is a draw due to impossibility of checkmate. A draw by threefold repetition or the fifty-move rule may be claimed by one of the players with the arbiter (normally using his score sheet), and claiming it is optional. The draw by fivefold repetition or the seventy-five-move rule is mandatory by the arbiter.
A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), [3] or after many moves with as few as three pieces in an endgame position.
In a two knights endgame, the side with the king and two knights cannot checkmate a bare king by force. This endgame should be a draw if the bare king plays correctly. A mate only occurs if the player with the bare king blunders. In some circumstances, if the side with the bare king instead has a pawn, it is possible to set up this type of ...
Diagram 1 is a draw, because the rook can give a perpetual check from f7, g7, and h7. [15] The White king cannot cross to the e-file (because the queen would be lost to a pin), and the rook is immune to capture on h7 or g6 (e.g. 1...Rg7+ 2.Kf6 Rg6+! forces a draw) because stalemate would result. [ 15 ]
Both players agree to a draw after one of the players makes such an offer. In addition, in the FIDE rules, if a player has run out of time (see below), or has resigned, but the position is such that there is no way for the opponent to give checkmate by any series of legal moves, the game is a draw. [28]
A queen wins against a lone rook, unless there is an immediate draw by stalemate or due to perpetual check [3] (or if the rook or king can immediately capture the queen). In 1895, Edward Freeborough edited an entire 130-page book of analysis of this endgame, titled The Chess Ending, King & Queen against King & Rook.
White moves first, followed by Black; then moves alternate. The object of the game is to checkmate (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw. The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India.
The game ended in a draw on move 129, because checkmate was impossible. Before the end, two insignificant underpromotions to bishops occurred. Vidmar vs. Maróczy, 1932
