Solution

Seki


Ko

[Diagram]

Black makes ko

After W3 this position is a throw-in ko. Either player can make a ko, but the other player takes first.

This is slightly preferable for Black if he is komaster.

-- Bill Spight

Mef: After W3 if Black ignores, can't white play at [circled point] for a favorable ko?

Bill: Black shouldn't play B2 if the ko fight is favorable for White. (The ko is favorable for the player who can win the ko fight.)
