Keryo-Pente was proposed in 1983 by World Pente Champion Rollie Tesh as a way to balance tournament play. The first Keryo Pente tournament took place on June 16, 1984. Keryo-Pente is similar to Pente, changing only the capture rules. As in Pente, If you place five or more stones in a row in any direction, horizontally, vertically, or diagonally, you win the game. You may capture pairs like Pente, and in addition you may capture three stones in a row by the same custodial capture method. If you capture 15 or more stones you win the game.
