Interesting game. I didn't like .. h6 and .. g5 by Rybka in the opening (as I
suspect most human players won't), and there were a few moments in the endgame
where better resistance could have been put up - but these are relatively minor

The biggest issue was the incorrect sacrifice of the h6 pawn. The Rybka static
eval incorrectly gives the following position (and others of a similar type) as
roughly equal:

[D] 8/1b2b1k1/pp1ppp2/nPq5/P1P1P3/2QRNPP1/8/1N2KB1r b - - 0 27

I'll keep to myself my proposed solution. It's a tricky issue and won't be
handled until after the Rybka 1.2 release. If anybody wants to share here, I am
all ears :-)
