Black to play.

Solution
Black’s sacrifice technique with 3 and 5 is the key. This provides the two other black stones an extra liberty that allows Black to win a local capturing race with 7–11.

This problem was created by Lee Eodeokdung 1p. He showed to me at the European Go Congress 2017, and it quickly became one of my favourite tsumego.

Black to play.

Solution
White 2 is the strongest resistance to Black’s attachment of 1. Following...
...after black 7, White dies in a double ko. This is still better for White than dying unconditionally, as the group will supply infinite ko threats.
