The correct procedure for an offer of a draw is to first make a move, verbally offer the draw, then press the clock. Otherwise, the offer or claim is nullified and the game continues the draw offer is no longer in effect. If the claim is verified or the draw offer accepted, the game is over. Once a claim or draw offer has been made, it cannot be withdrawn. The draw by fivefold repetition or the seventy-five-move rule is mandatory by the arbiter.Ī 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. 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 stalemate is an automatic draw, as is a draw due to impossibility of checkmate. In games played under time control, a draw may result under additional conditions. The rules allow for several types of draws: stalemate, threefold or fivefold repetition of a position, if there has been no capture or a pawn being moved in the last fifty or seventy-five moves, if checkmate is impossible, or if the players agree to a draw. It is now standard practice to score a decisive game as one point to the winner, and a draw as a half point to each player. In the 19th century, some tournaments, notably London 1883, required that drawn games be replayed however, this was found to cause organizational problems due to the backlog. For example, a draw could be called after a move or two, but this would likely be thought unsporting. Ethical considerations may make a draw uncustomary in situations where at least one player has a reasonable chance of winning. Unless specific tournament rules forbid it, players may agree to a draw at any time. Under the standard FIDE rules, a draw also occurs in a dead position (when no sequence of legal moves can lead to checkmate), most commonly when neither player has sufficient material to checkmate the opponent. Draws are codified by various rules of chess including stalemate (when the player to move is not in check but has no legal move), threefold repetition (when the same position occurs three times with the same player to move), and the fifty-move rule (when the last fifty successive moves made by both players contain no capture or pawn move). In chess, there are a number of ways that a game can end in a draw, neither player winning. A king and one bishop versus a king cannot create a checkmate on either player. (These are the only entries in the table with the opposing king as the sole defender.) Any other pieces or pawns added would reduce the necessary number of moves.Draw by insufficient material. See Wikipedia again for a table: a queen takes at most 10 moves to mate with best play, a rook takes at most 16, two bishops 19, and bishop and knight (as mentioned) 33. In other cases, mate could be forced sooner. However, this scenario is extremely improbable, as a quicker mate would certainly be preferred.Īs to the first question, if you only have a king, and your opponent has sufficient material to force mate, the minimum necessary number of moves in all positions would be 33 - in the case of King, Bishop, and Knight against King. The game could go on for over 3000 moves before it must end ( * 50 moves = 3100 moves). Theoretically, if you have lost all your pieces and he has lost none of his, he could jockey pieces around (making sure not to allow the same position three times) while every 50 moves moving a pawn or forcing you to capture a piece. As long as the same position is not reached more than twice and there is no 50 move stretch without a pawn move or capture, the game can go on until there are no pieces left. Tony has already answered the second question - it could legally be thousands of moves depending on the position. Do you mean "what is the minimum necessary number of moves?", or "what is the maximum allowable?"
