Currently unavailable on Amazon, the mysterious game of Three-Man Chess pitches grey pieces into the time-honoured battle of black and white.
How this unholy mutant is supposed to work is anyone’s guess. The product description isn’t that helpful:
Play chess with 3 people at the same time with this three player chess game. Without compromising any of the rules, strategy, or fun of Chess, this variant board has been developed that accommodates three players. The only changes from conventional chess are some protocol issues that must be followed to maintain order where the teams border each other, which is simple and necessary.
The complexities of the third player are infinite. Your threatened piece may be allowed to maintain occupancy as your position is beneficial to the threatening player. But how long can it last? This scenario may exist all over the board. There are multiple trust and doubt situations among all players.
