OD1P - July 28 Problem / Solution2

Sub-page of OD1PJuly28Problem
Black first, White dies  

We shall start off from B1 instead...

The solution is presented below.

Discussions welcome.



BillSpight: B3 is tesuji, but W4 makes a and b miai for a second eye. This is a diagram in the Sekiyama book to show that B1 is a mistake.

However, it looks like the vulgar play works.


That very interesting tesuji!  
Variation 1 (a)  

If B7 is played at B9 instead, then White takes the stone at B7 and it becomes a ko. (B7 at W10 produces another ko; I've added it as "Variation 1 (c)" below. Dieter)

Variation 1 (b)  

After the placement at B1, a and b are miai. White is dead.

Variation 1*: Ko (added by Dieter)  

If W6 as marked, then B7 at a. It is a ko.

Variation 2 (a)  
Variation 2 (b)  

(B3 at white+circle)

With B3, White dies with a farmer's hat eye shape.

Variation 3  

This variation reverts to Variation 1.


Finally, White's resistance at W2 is useless. B3 descends, and a and b are now miai.
