Hi,

Thanks for the game. I have not analyzed the game in depth, but the 
problem is probably that you played with a komi of 6.5. What looks like 
a blunder by Crazy Stone is in fact a desperate attempt to win in a 
position that is already completely lost. Crazy Stone plays differently 
depending on the komi. It tries to maximize the probability of winning, 
not the expected territory. The right komi for 7x7 seems to be 9.

You have to show the analyze window (menu settings/show analyze, or F9). 
In the list of analyze commands, double-click on ::MCSearch::Parameters. 
It will display a dialog box with some options. Uncheck "Use opening book".
