It was a second round in Mondays club, my opponent was a young man rated 1543.  I had White and played again Closed Sicilian. Some complications arose after 12.  Nd5, computer doesn’t like his 14… Be5, preferring Qb8. Move 20. g4 was apparently not the best, better was h4 with following Bh3 and exchanging the bishops.  It allowed White to attack h6 and f7 squares.

Around move 25 I had a feeling that I have a good pressure and spent quite some time looking for the best continuation. His 27… Qc5 was a crucial mistake, he tried to avoid pin, but his queen stopped defending the king. The intention of 29. Qf3 was to sacrifice an exchange on e6.

Suddenly he sacrificed exchange himself. I considered quickly taking the rook, didn’t like it and decided to continue with my plan. So I took on e6. When he played fxe6, it became clear that he is in trouble. He resigned after my 32. Qxe6. Computer found here mate in 10: 32…. Kg7 33. Qg6 Kh8 34. Qxh6 Kg8 35. Qe6+ Kh8 36. Qe8+ Kh7 37. exd5 Qd6 38. Be4+ Kg7 39. Kg3 Nd4 40. h6+ Kxh6 41. Qh5+ Kg7 42. Qh7#. Interesting that all the pieces and two pawns that were attacking the king take part in this mate.

By the way taking his rook was winning too. After 30. exd5 Qxd5 31. Rg6+ mates in 5 and after 30… Bxd5 31. Qf5 White wins.
