My opponent was an old guy, I played him a couple of times in the past and won. I had White and he played Sicilian, French variation. I was not inclined to play d4, so I played c3 instead.

His 5… Nc6 didn’t look right to me, I saw c4 right away and after some thinking played it. Then 9… b5 was really bad, I just had to see that I should take with the bishop, not knight, taking into account a possible queen check after knight’s exchange.

Computer thinks that 12. Bc4 was better then my 12. 0-0. Anyway he played soon 13… d6, opening lines for attack on his own king. After 14. exd6 he realized that and resigned, computer gives me about +5 in this position.
