Task: Question Generation
Input (English): A check is a condition in chess, shogi, and xiangqi that occurs when a player's king (or general in xiangqi) is under threat of capture on their opponent's next turn. A king so threatened is said to be in check. A player must get out of check, if possible, by interposing a piece between the threatening piece and the king, capturing the threatening piece, or moving the king to a square where it is no longer in check. If the player cannot move out of check, the game ends in checkmate and the player loses. Players cannot make any move that puts their own king in check.
Output (English): can you only move the king in check?
