Article 5: The completion of the game
5.1 a. The game is won by the player who has checkmated his opponent’s king. This immediately ends the game, provided that the move producing the checkmate position was in accordance with Article 3 and Articles 4.2 — 4.7.
b.The game is won by the player whose opponent declares he resigns. This immediately ends the game.
Article 5.1 gives the two ways that ‘normal’ games end in victory. The tournament rules give the possibility of other ways of winning.
Article 5.1 (b) If a player believes he has been checkmated and subsequently, during the post mortem for example, discovers that he was not then that player is deemed to have resigned.
5.2 a. The game is drawn when the player to move has no legal move and his king is not in check. The game is said to end in ‘stalemate’. This immediately ends the game, provided that the move producing the stalemate position was in accordance with Article 3 and Articles 4.2 — 4.7.
b. The game is drawn when a position has arisen in which neither player can checkmate the opponent’s king with any series of legal moves. The game is said to end in a ‘dead position’. This immediately ends the game, provided that the move producing the position was in accordance with Article 3 and Articles 4.2 — 4.7.
c. The game is drawn upon agreement between the two players during the game. This immediately ends the game.
d. The game may be drawn if an identical position is about to appear or has appeared on the chessboard at least three times (see Article 9.2).
e. The game may be drawn if each player has made at least the last 50 moves without the movement of any pawn and without any capture (see Article 9.3).
Article 5.2 (c) Some tournament rules prevent draw offers either at all or before a specified number of moves (see 9.1) without the agreement of the arbiter.
Article 5.2 (d) If a player accepts a ‘draw by repetition’ claim and subsequently discovers that the claim was incorrect then the draw still stands. The player would be deemed to have agreed to the draw. The rules do not cover what happens if this incident was before the allowed prescribed number of moves for a draw offer!
Article 5.2 (e) This article is wrongly assumed by some players only to apply in the endgame. It is relevant throughout the game.}
