We've all seen it before, 2 people playing chess and 1 person watching. Now with this 3 man chessboard, they can all play at the same time. The rules are the same, the pieces are the same, and the moves are the same. The only difference is the extra person playing. If you are skilled enough, you can checkmate both opponents at the same time. The creator says "Defense is crucial since a diagonal move through the center, or a horizontal move around the center can sneak up behind you." Looks like a ton of fun for chess lovers.
