Rules of Pair Go®
Apart from the special rules of Pair Go, in principle the Japanese Rules of Go (adopted April 10, 1989) are applied.
- 1. Pair Go®
- In principle, the game is played between male-female pairs. the two players in each pair are called partners.
- 2. Seating
- the two partners sit beside each other, facing the opposing pair across the Go board. the male player sits facing the male player and the female player facing the female player.
- 3. Order of moves
・the pairs play in the following order:…→●Black female player→○White female player→●Black male player→○White male player→…
this cycle is called the normal rotation. the players must always play in the normal rotation.
・the player who makes the first move of the game is as follows:In non-handicap games, the Black female player makes the first move. (the next move is made by the White female player.)
In games with a handicap of two stones or more, the White female player makes the first move. (the next move is made by the Black male player.)
- 4. Prohibition on exchanging information
- During the game, partners must not communicate, give advice, or exchange other information by speech, gestures, mannerisms, or any other means except playing moves. Speaking is permitted, however, to confirm whose turn it is to play or to confer about resigning. Conferring about resigning is limited to the following case: the player to move may ask for his or her partner's consent to resign; the partner may agree or not agree to resign.
- 5. Resignation
- Resignation is announced by the player whose turn it is to move. the player's partner cannot retract the resignation.
- 6. Violations
If the wrong partner plays, causing a departure from normal rotation, this is called a rotation error. Rotation errors are handled as follows:
Example of rotation error and return to normal rotation
- (1) A rotation error can be claimed only when the move just played was out of rotation.
- (2) If the claimed rotation error was intentional, the game is forfeited immediately.
- (3) If the claimed rotation error was unintentional, the next step is to verify which partner played the preceding move.
- (4) If the preceding move was played in normal rotation, the game continues with a three-point penalty for the claimed rotation error.
- (5) If the preceding move was not played in normal rotation, the game continues without any penalty for the claimed rotation error.
- (6) In either case, no moves are taken back and replayed. the last move played is regarded as having been played by the correct player. the next move must be played in normal rotation with the last move played.
- (7) Whenever a rotation error is detected, the next player must return to normal rotation. Failure to do so is regarded as a new rotation error.
- ●Black male player Normal : rotation
- ○White male player Normal : rotation
- ●Black female player Normal : rotation
- ○White female player Normal : rotation
- ●Black female player : Rotation error. the error is claimed and a three-point penalty is applied.
- ○White female player : Return to normal rotation (the White female player normally plays after the Black female player).
If the White male player played at this point , that would be a new rotation error.
- ●Black male player : Normal rotation
- ○White male player : Normal rotation
- ●Black female player : Normal rotation
- ○White female player : Normal rotation
Illegal exchange of information
If an illegal exchange of information between partners is observed to take place, the offending pair forfeits the game.
- 7. Other matters
- (1) the game stops when there are two consecutive passes.
- (2) the word "agreement" in the Japanese Rules of Go means agreement among all four players.
Pair Go® Handicap Rules
- 1. Handicap setting
Players who have held amateur titles receive 9 handicap points. Players who have represented their prefectures in amateur title tournaments receive 8 handicap points. Other players receive handicap points as follows:7D→7、 6D→6、 5D→5、 4D→4、 3D→3、 2D→2、 shodan→1、 1kyu→0、 2kyu→-1、 3kyu→-2、 4kyu→-3、 5kyu→-4、 6kyu→-5
the handicap points of a pair are the total of the two partners' handicap points divided by two.
・Examples of handicap-point calculations for pairs A's points 6 4 5 2 -3 B's points 2 1 -1 -4 -4 Pair's points 4 2.5 2 -1 -3.5 ※A and B are the partners in a pair.
- 2. Handicaps
・The handicap in a game is determined by the difference in handicap points between the pairs as follows:
