In chess, dirty flag refers to a scenario in which a player having a losing position on the board wins by virtue of the opponent exceeding the time control. It typically occurs in faster formats, such as blitz or bullet, where a player prioritizes making rapid (often sub-optimal) moves to exhaust the opponent's remaining seconds rather than seeking a tactical or positional advantage.
