If it is your move, you have less than 2 minutes remaining on your clock, and your flag is still up, in certain circumstances you may stop both clocks and ask a tournament director to declare the game a draw based upon insufficient losing chances. This is different from a “book draw,” and requires a position in which a Class C player (1500 rating) has a greater than 90% chance of avoiding a loss to a Master (2200 rating) with ample time for both. It is a judgment call by the Tournament Director whether or not to allow the claim. You can claim such a draw with King and Queen vs. King and Queen, King and Rook vs. King and Rook (no other material), in many opposite-color Bishop endings, or if you have an overwhelming material advantage, such as King, Queen, and four Pawns vs. King and a single blocked pawn, (in this case, you would be claiming the draw only because you lack sufficient time to force a checkmate). But a position such as King, Rook, and a Pawn for each side, even if “drawn” in theory, would probably allow a Master too great a chance to outplay a C player, so your claim would likely be denied. If a game is being played using a clock’s time-delay feature, no claims of insufficient losing material will be considered, since a player in such a position should be able to maintain his/her game without running out of time. This game would likely be drawn by the 50-move rule or the threefold repetition rule.
A Tournament Director has four choices when asked to rule on an insufficient losing chances claim. He/she may (1) declare the game a draw, (2) deny the claim, and if the claim is deemed frivolous or obviously incorrect, deduct one minute from the claimant’s time, (3) if the validity of the claim is uncertain, temporarily deny the claim, making no adjustment of the claimant’s remaining time, and inviting the claimant to make the claim again later, if the opponent is making no progress, (4) if the game is not already being played with a time-delay clock, replace the game clock with a clock set for a 5-second delay, with the time per side adjusted so that the claimant has one-half of his/her remaining time, and the opponent has all his/her time remaining. The game then continues to completion, using the delay mode. This last method is the preferred choice for some TDs and can be used during this tournament at their discretion. This is called liberal clock substitution. It is recommended that players find out the section chief's preference for clock substituting.
A claim of insufficient losing chances is also an offer for a draw, and if the opponent accepts this implied draw offer, the game is drawn. Note that any draw claim is a draw offer. Even if the TD turns down the draw claim, the draw offer is still in effect.
