Tsumego From Games 15 Attempts
    Keywords: Problem

[Diagram]
Attempt

If Black 2 protects at 3, White has one more liberty. -- Confused


[Diagram]
Attempt

If Black plays 2 like this, the situation becomes ko (difficult to win for Black, but still ko).

--Herman


[Diagram]
Removing ko options

Playing at 1 removes any chance of getting into ko. Black cannot play a, since White has one liberty more. If Black plays b, White plays c and vice versa.

--Herman



unkx80: Herman has given the correct answer. In this game I was Black. If White had played 1 as in the correct answer, I would have lost the game. But I won. =)
