how many passes to end the game
In theory (explained later) a game should end after 3 passes? but different rule sets have rules about this point.
Some rule sets (AGA rules)prescribe that White needs to make the last pass because thatis to create equiovalence between area scoring and territory scoring
But here the discussion is more fundamental.
The main problem is what bappens with a ko after a pass.
Suppose black just played capturing
, White passes and Black passes as well. if the game ends with 2 passes the game is over.
If White has to make the last pass may she not retake the ko instead? (and continue the game)
If the game ends after 3 moves black could do the same if the colors were inverted.
The easy answer if off course that Black should have captured a any of the stones after the White pass teire but precribing moves is a bit against the grain of the game. (and teire is only prescribed in Japanese rules)
and why is black not allowed to makes mistakes?
