Keywords: Life & Death
Solution
Ko
After 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.

Mef: After if Black ignores, can't white play at
for a favorable ko?
Bill: Black shouldn't play if the ko fight is favorable for White. (The ko is favorable for the player who can win the ko fight.)
