 at any time. Ethical considerations may make a draw uncustomary in situations where at least one player has a reasonable chance of winning. For example, a draw could be called after a move or two, but this would likely be thought unsporting.

Until 1867, tournament games that were drawn were replayed. The Paris tournament of 1867 had so many drawn games to be replayed that it caused organisational problems. In 1868 the British Chess Association decided to award each player a half point instead of replaying the game .

, a draw may result under additional conditions . A stalemate is an automatic draw, as is a draw because of insufficient material to 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.

A claim of a draw first counts as an offer of a draw, and the opponent may accept the draw without the arbiter examining the claim. Once a claim or draw offer has been made, it cannot be withdrawn. If the claim is verified or the draw offer accepted, the game is over. Otherwise, the offer or claim is nullified and the game continues; the draw offer is no longer in effect.

An offer of a draw should be made after a player makes a move but before he presses his game clock

 gives the ways a game may end in a draw, and they are detailed in Article 9: .
  • Stalemate
    Stalemate
    Stalemate is a situation in chess where the player whose turn it is to move is not in check but has no legal moves. A stalemate ends the game in a draw. Stalemate is covered in the rules of chess....

     - if the player on turn has no legal move but is not in check, this is stalemate and the game is automatically a draw.
  • Threefold repetition
    Threefold repetition
    In chess and some other abstract strategy games, the threefold repetition rule states that a player can claim a draw if the same position occurs three times, or will occur after their next move, with the same player to move. The repeated positions need not occur in succession...

     - if an identical position has just occurred three times with the same player to move, or will occur after the player on turn makes his move, the player on move may claim a draw (to the arbiter). In such a case the draw is not automatic - a player must claim it if he wants the draw. When the position will occur for the third time after the player's intended next move, he writes the move on his scoresheet but does not make the move on the board and claims the draw. Article 9.2 states that a position is considered identical to another if the same player is on move, the same types of pieces of the same colors occupy the same squares, and the same moves are available to each player; in particular, each player has the same castling
    Castling
    Castling is a special move in the game of chess involving the king and either of the original rooks of the same color. It is the only move in chess in which a player moves two pieces at the same time. Castling consists of moving the king two squares towards a rook on the player's first rank, then...

     and en passant

    capturing rights. (A player may lose his right to castle; and an en passant capture is available only at the first opportunity.) If the claim is not made on the move in which the repetition occurs, the player forfeits the right to make the claim. Of course, the opportunity may present itself again.
  • The fifty-move rule - if in the previous fifty moves by each side, no pawn

    The pawn is the most numerous and weakest piece in the game of chess, historically representing infantry, or more particularly armed peasants or pikemen. Each player begins the game with eight pawns, one on each square of the rank immediately in front of the other pieces...

     has moved and no capture has been made, a draw may be claimed by either player. Here again, the draw is not automatic and must be claimed if the player wants the draw. If the player whose turn it is to move has made only 49 such moves, he may write his next move on the scoresheet and claim a draw. As with the threefold repetition, the right to claim the draw is forfeited if it is not used on that move, but the opportunity may occur again.
  • Impossibility of checkmate
    Checkmate
    Checkmate is a situation in chess in which one player's king is threatened with capture and there is no way to meet that threat. Or, simply put, the king is under direct attack and cannot avoid being captured...

     - if a position arises in which neither player could possibly give checkmate by a series of legal moves, the game is a draw. This is usually because there is insufficient material left, but it is possible in other positions too. Combinations with insufficient material to checkmate are:
  • king
    King (chess)
    In chess, the king is the most important piece. The object of the game is to trap the opponent's king so that its escape is not possible . If a player's king is threatened with capture, it is said to be in check, and the player must remove the threat of capture on the next move. If this cannot be...

     versus king
  • king and bishop versus king and bishop with the bishops on the same colour. (Any number of additional bishops of either color on the same color of square due to underpromotion do not affect the situation.)
  • Mutual agreement
    Draw by agreement
    In chess, a draw by agreement is the outcome of a game due to the agreement of both players to a draw. A player may offer a draw to his opponent at any stage of a game; if the opponent accepts, the game is a draw. The relevant portion of the FIDE laws of chess is article 9.1...

     - a player may offer a draw to his opponent at any stage of a game, ostensibly with the understanding that an eventual draw by other means is the likely result. If the opponent accepts, the game is a draw.


It is popularly considered that perpetual check

Such a situation typically arises when the player who is checking cannot deliver checkmate; while failing to continue the series of checks gives the opponent at least a chance...

 – where one player gives a series of checks from which the other player cannot escape – is a draw, but in fact there is no longer a specific rule for this in the laws of chess, because any perpetual check situation will eventually be claimable as a draw under the threefold repetition rule or by the fifty-move rule, or (more likely) by agreement . By 1965 perpetual check was no longer in the official rules .

Although these are the laws as laid down by FIDE and, as such, are used at almost all top-level tournaments, at lower levels different rules may operate, particularly with regard to rapid play finish provisions.

Examples

Draws in timed games

, there are other ways a draw can occur , .
  • In a sudden death time control (players have a limited time to play all of their moves), if it is discovered that both players have exceeded their time allotment, the game is a draw. (The game continues if it is not a sudden-death time control.)

  • If only one player has exceeded the time limit, but the other player does not have (theoretically) sufficient mating material, the game is still a draw. Law 6.9 of the FIDE Laws of Chess states that: "If a player does not complete the prescribed number of moves in the allotted time, the game is lost by the player. However, the game is drawn, if the position is such that the opponent cannot checkmate the player's king by any possible series of legal moves, even with the most unskilled counterplay." For example, a player who runs out of time with a king and queen versus a sole king does not lose the game. It is still possible to lose on time in positions where mate is extremely unlikely but not theoretically impossible, as with king and bishop versus king and knight.

  • Because of this last possibility, article 10 of the FIDE laws of chess states that when a player has less than two minutes left on their clock during a rapid play finish (the end of a game when all remaining moves must be completed within a limited amount of time), they may claim a draw if their opponent is not attempting to win the game by "normal means" or cannot win the game by "normal means". "Normal means" can be taken to mean the delivery of checkmate or the winning of material. In other words, a draw is claimable if the opponent is merely attempting to win on time, or cannot possibly win except on time. It is up to the arbiter to decide whether such a claim will be granted or not.

 a position is considered to be a draw if best play leads to a draw – the difficulty of the defence is not taken into account. Soltis calls these positions "drawable". For instance, under that criteria the rook and bishop versus rook endgame is usually a theoretical draw or "book draw", but the side with the bishop usually wins in practice. In this position from an actual game, the only move to draw is 124. Rf8! White actually played 124. Rd8?? and lost .
