It was a third round in the Monday’s club championship, I played there first time in 2 months. My opponent was an old guy, FIDE master, it was his first tournament since 2012. I knew I could play him with Black, saw that he plays Vienna game and prepared a bit. So his first moves were not a surprise for me.

His 6. g3 is not considered a good move and 7. Qe2 was a mistake. I could play 7… Ng5 8. Bg2 Nc6 9. Qf2 Nb4 10. Nxg5 Nxc2+ 11. Kf1 Bxg5 with advantage. After he castled queenside I tried to create an attack. I think his light pieces exchange defused the situation. Then I made a blunder putting my rook on f8.

Computer considers 23. Qxc6 not the best move, preferring Qe3. It also says that 29… h5 is better than Nc5. I realized after the game that 34… exd5 was better than cxd5 in the game. He played well this part of the game and his position was becoming stronger and stronger. I saw Bxe6 sacrifice, but was not sure it was winning. He decided to play it and soon I had to resign.
