It was a second round in the new club. My opponent was a veteran rated 1980, playing from 1997. He had Black and played Modern Defense. I don’t know it well, the book says I had to play 5. Qd2. Still it was equal after move 21. Then the tension increased.

Computer doesn’t like his 22… Nh6, preferring Nf6. My 23. Qc3 did’t use it, computer says I had to play g4. I probably wouldn’t look suspiciously at it knowing what happened next. I could play it even 6 moves later, giving up f5 and g3 squares was a mistake.

My position started to deteriorate, letting him play b5 was another mistake. I was getting worse and worse, still continued to play. After 50 moves it became hopeless and I resigned.
