how many passes to end the game

    Keywords: Rules

In theory (explained later) a game should end after 3 passes? but different rule sets have different rules about this point.

Some rule sets (AGA rules) prescribe that White needs to make the last pass because that is to create equivalence between area scoring and territory scoring.

But here the discussion is more fundamental.

The main problem is what happens with a ko after a pass.

[Diagram]

Suppose Black just played B1, capturing white+circle, 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 of course that Black should have captured any of the stones white+triangle after the White pass teire but prescribing 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?
