We shall start off from instead...
The solution is presented below.
Discussions welcome.

BillSpight: is tesuji, but makes a and b miai for a second eye. This is a diagram in the Sekiyama book to show that is a mistake.
However, it looks like the vulgar play works.
Solution!!!

![[Diagram]](../../diagrams/44/b050206716bb82db7c1064e907f47178.png) | Variation 1 (a) |
If is played at instead, then White takes the stone at and it becomes a ko. ( at produces another ko; I've added it as "Variation 1 (c)" below. Dieter)
![[Diagram]](../../diagrams/30/c5206eb673551ef39c7a94362a2ce01b.png) | Variation 1 (b) |
After the placement at , a and b are miai. White is dead.
![[Diagram]](../../diagrams/10/cec994c3a4fb2a69a1d6a082d5eab1a2.png) | Variation 1*: Ko (added by Dieter) |
If as marked, then at a. It is a ko.
![[Diagram]](../../diagrams/24/9f69ef9eff5b97f768057dad033b7dc9.png) | Variation 2 (a) |
![[Diagram]](../../diagrams/46/837f1476ac28e0f0b447c01dc0c4093f.png) | Variation 2 (b) |
( at )
With , White dies with a farmer's hat eye shape.
![[Diagram]](../../diagrams/29/35c39d134a704eb4c5f2009f5dd98978.png) | Variation 3 |
This variation reverts to Variation 1.
![[Diagram]](../../diagrams/27/fc7085483d4b2727f84ceba89e3c61c8.png) | Finally |
Finally, White's resistance at is useless. descends, and a and b are now miai.
