Play 2vs2 with 2 unseen players and 4 enemies.

This variant is played on two boards. At each board sits one player from each team and they play a game against each other. They are not allowed to see the other board. However, all four players are actually playing on the same board which only the referee can see. After each move, the referee checks if the move is allowed and request a take-back otherwise. The reason (e.g. suicide, immediate retake of a ko) is not given. If stones are captured, they are removed by the referee and the total number of stones is announced.

* Starting time: Monday, 31st of July.
There are two alternative dates to play Phantom Rengo, starting at 1pm and at 6pm.
Please register for only one of the dates.
