Gokyo Seimyo Volume 3 Problem 10 / Attempts

[Diagram]

White can't resist this way...

The peep threatens this sequence, leading to a snapback with B5. White will obviously not do this.

[Diagram]

First force the capture...

If black continues with the sequence to 5 then it will play out to seki as per the following diagram.

[Diagram]

Continuation - seki

White is happy with seki.

However, black will not continue with a, but follow this sequence...

[Diagram]

Continuation - death

Black will not play a, but play 1, in which case the whole white groups dies since both sides are in damezumari.

[Diagram]

life in gote

Given that, the best white can do is to give up 4 stones and live with the rest of his group in the corner in gote. If they do not defend with 4 trying to tenuki after the a/b exchange black can make ko for the whole group.
