Wizard's Chess

Wizard's Chess is the magical variant of the classic board game, except the pieces are alive. When a piece is taken, the peace that it is taken by smashes it. Players move their pieces by speaking the name of the piece, and the square they are to move to. When Harry Potterbegan to learn how to play the game, he used the pieces of Seamus Finnigan, which offered him advice because they knew that he was not a good player.

A giant Wizard's Chessboard was the third-to-last layer of security for the Sorcerer's Stone, and Harry, Ronald Weasly, and Hermione Granger managed to get past it, Ron giving himself to the White Queen so that Harry could checkmate the King.
