Bughouse is a fast-paced team chess variant played on two boards. Each team consists of two players, and when a player captures an opponent's piece, they pass it to their teammate, who can then place it on their own board. This adds a unique layer of strategy, as players must coordinate with each other while managing their own game. The game is typically played with standard chess rules, but the dynamic of sharing pieces creates exciting opportunities and challenges. Bughouse is popular in casual settings and tournaments, fostering teamwork and quick thinking among players.
