It was a first round in the first tournament of the season , because of the problem during registering I was manually paired with my friend rated 1518.  We had 6 draws in the past, his rating dropped lately. He played English Opening, I replied with c6.  His 15. f3 was slow, I expected e4. His 18. Bh3 looked strange, 18… Ne8 (with the idea of Ne8-Nd6-Nc4) was better than my 18… Rc7.

After his 20. g4 I evaluated the position and decided that knight on f6 and bishop moved to f8 could hold it. So I continued my initiative on the queenside. Instead of his 24. Rc2 computer offers 24. fxe6 Nxb2 25. exf7+ Kf8 26. Qg6 b4 27. Rf2 bxc3 28. Rg2 Ng4 29. Qh7 Bf6 30. Bxg4, with some attack (for the knight for two pawns) with -1.5 estimate.

Then I found 24… e5, I thought it was stopping completely his attack. He had to play 25. dxe5 Nxe5 26. Qd4, still after queens exchange Black was better. After 25. Bc1 his position continued to deteriorate and he resigned after 35. Rxh3.
