The Mating Game is a chess variant in which the goal is to checkmate the opponent's king. It was invented by International Master John Watson in 1997 and is played on a standard 8x8 chessboard. The game is similar to regular chess, but with some additional rules that make it more challenging. Players must use their pieces to capture their opponent's king, while also protecting their own king from being captured. The game can be played with two players or teams of two.
