Flag hanger is a pejorative term for a player who refuses to resign a clearly lost position in a timed game, continuing solely in the hope that the opponent’s clock will run out before checkmate can be delivered.

The term comes from the red flags on older mechanical chess clocks that drop when time expires. A flag hanger is not looking for a swindle or complications that might change the result; the only remaining aim is a time forfeit victory.

At club level this conduct is widely regarded as poor sportsmanship. Once the position is objectively hopeless—typically a large material deficit with no compensation and a safe enemy king—standard etiquette calls for resignation so both players can start the next game without delay. Prolonging the game simply wastes the winner’s time and can disrupt a tournament schedule.

Rulesets do not forbid continuing play. FIDE and most national federations allow a player to stay at the board until checkmate occurs or the flag falls. The only restrictions are against deliberate stalling, such as repeatedly moving the same piece back and forth without purpose, or making obviously illegal moves in an attempt to gain time.
