Great win terry. and done without an anti-computer style!!!!

This Bxh6 seems like it was not a strong move, allowing the queen to get to the
important h6 square. (Maybe this move was forced with the coming of the opened h
file and q getting to h6 with check anyway!)

 I have noticed in other games that rybka seems too willing to give up its
fianchettod bishop in these kind of positions

I think computers are sometimes too cold blooded. I have faced this kind of
position alot, and I can tell you how a human responds: "Sweet god, why the hell
do i play the dragon!!! After this game I am taking up the karo kann." Then,
after i've lost five minutes on my clock panicking, i think " I've got to do
something, anything. " Then maybe I make the typical exchange sacrifice, rxnc3
or something very desperate looking.
