"crazyhouse chess"的定义和意义

What is "crazyhouse chess"?

Crazyhouse chess is a chess variant where captured pieces can be returned to the board by the player who captured them. When a player captures an opponent's piece, they gain control of it and can place it on any empty square of the board as their own piece. The goal of the game is the same as traditional chess: to checkmate the opponent's king. Crazyhouse adds an extra layer of strategy, as players must not only plan their moves but also think about how to use the captured pieces effectively. This makes the game faster and more dynamic compared to regular chess.
