Pretty cool endgame problem

[Bill Spight]

gonuts solved the subproblem.



White gets one point more in this variation than in the main variation.

[Bill Spight]

What is White's play after in the variation?

Endgames are the worst part of my game, except for joseki, fuseki, middle game, yose, and tsumego. But here goes an attempt to answer Bill's last question anyway...

[Bill Spight]

gonuts has solved this subproblem too.

I have added some comments to his SGF file.



And that means that, along with his earlier work, gonuts has solved the original problem, as well. Correct play for Black in it is the atari at A-03, which yields this subproblem.

The end result is the same as in the main line in Gokyo Seimyo, so I did not find an improvement. And that line is cool for both players. However, I thought that the atari (A-03) was pretty cool. The cut (A-05), while it looks natural, loses a dame and, hence, 1 point by comparison.

This also gives the same result as the main line.
