While the board is similar to a chess board and the various pieces are similarly designed to have various offsetting abilities, when one piece attempts to take another the removal of the targeted piece is not automatic. Instead, the two chess pieces are placed into a full-screen 'combat arena' and must battle (arcade-style, with the players running the pieces) to determine who takes the square. Generally (but not always) in combat, a stronger chess piece will succeed over a weaker chess piece in either defending or capturing a square. It is also possible for the fight to result in a double-kill, in which both pieces are eliminated. This uncertainty adds a level of complexity into the game, since it is not always possible to predict if taking a square will be successful.
