Good luck.

Of the people I have shown this to on KGS, I can tell you that Tien read most of the variations in his head and only missed one when I showed him the answer. So if you can figure this out in your head, you are quite strong.

Reminds me of a quote from my blog tidbit on Cho Chikun's thoughts on the importance of calculation.

Quote:
Though we think of a game as being quite a distance from calculation and life and death problems, a game will still come to a stage requiring fierce contact fights. At such time, calculating skill will be most important.

...Beyond me :P.

I want to threaten to capture G11 to create a splitting attack between L8 and D11, but really I'm just restating the problem; black's centre looks a little thin. J9 K9 J10 ...K11? is it even necessary? H10 G11... H11? But H11 doesn't really look sente and can be cut off itself...

White has many center moves that quickly lead nowhere. Only one move seems to give White any chance, although I'm sure I'm missing Black's best defense.

Nice problem, tchan. Thanks!

It was a long while ago when I posed the problem to him so I can't quite remember which variation he missed unfortunately
