Yesterday was a first round of a regular Swiss tournament.
I couldn’t decide until the last moment in which section – 2000+ or U2000 I should play (you can play 100 points up), finally went to U2000. Didn’t feel ready to play every time with masters/experts. I got the guy with whom I played a year ago and won with White in the endgame rather easily. This time I had Black and he played Scotch game, here it is. After queen exchange I thought that I am somewhat worse due to his pawn majority on the kingside (on the queenside I had doubled pawns). It looked like Ruy Lopez exchange, but without me having two bishops. But Fritz thinks that I was OK until move 14, when I moved my bishop to a5 allowing him to get bishop pair.
I didn’t play Bd6 being afraid of f4, but f4 wouldn’t work because of his bishop hanging on e3. I understand now that Black has here some dynamical counterplay.

Then I completely underestimated the strength of his queenside pawn attack thinking that without queen it’s not dangerous. It was, and 19… c5 was a game losing mistake, because after “a” vertical opened and pawn c7 dissappeared, dark-colored bishop became deadly. I lost an exchange and a pawn and could resign right there.
I played another 10 moves and then blundered in already very bad position. I spent about 50 minutes, he about 30. I have to admit that my opponent played well, much better than a year ago. I was extremely upset, today I calmed down a little bit.
A few things can be learned from this game, I’ll finish on that note.
