Torazu sanmoku = Three points without capturing.
The traditional Japanese ruling (by Honinbo Shuwa, according to the Esperanto link below) was that this corner position was worth 3 points for Black at the end, without his having to capture the marked white stones.
However, the Japanese '89 rules make this seki if it is left on the board at the end of the game, therefore Black should capture before the game ends (See diagram; may be delayed). The name is misleading and the same is true for another similar shape, Torazu Gomoku.
' ' However, the traditional Japanese Go rules call it “three points without capturing”, which means there are 3 points for Black. This obviously does not comply with present Japanese rules. But by the idea of "each side", even if White moves first and there are "equal stones", the result is still 3 points for White. This shows that the original Japanese rules are based on the concept of "each side", and "three points without capturing" is its legacy.' ' New In Go
(By "each side" Chen means that each player plays the same number of stones.)
