Tile Go is a finite Go variant without superko rules. It differs from Go in the following aspects:
Suicide is not allowed. The ko rule is used, but not the superko rule. Cycles, both forced and cooperative, are impossible. Cushion Go is the same as Tile Go, except you only place a tile when the last placement and your current placement are both in enemy territory. This more lenient rule makes all known Go forced cycles impossible, but does not eliminate cooperative cycles. In return, it keeps the game extremely close to Go. You can expect to place a couple of tiles per game, but this is usually not enough to render any Go moves illegal. Depicted below is the final position of the longest known high-level Go game as recreated (legally) under Cushion Go rules. The game lasted 417 moves. Only four tiles (marked with red circles) were needed, and the first tile was placed on move 298. For comparison, you can replay the game under Tile Go rules here. |
