In chess, a player can become "trapped" when their pieces are limited in mobility or unable to escape threats, leading to a checkmate or losing a key piece. This situation often occurs when a player's strategy fails to account for their opponent's moves, leaving them vulnerable. Being "trapped" emphasizes the importance of foresight and tactical planning in chess, as players must anticipate potential threats and adapt their strategies accordingly. Recognizing patterns and understanding positioning are crucial to avoiding this predicament during gameplay.
