For a start, here is a 15-min game with ICC computer ... I play White ...
After the game I checked the computer's setting and found-out that the rating is only 1400 and that explains the move 10... Bxg4
hope reader will learn something from my batil's analysis 
for here on I set the computer's rating to 2300+ ... ha ha ha
As promised, I will start to post games, puzzles, etc in this forum ... coming up ... ;-)
