B92 Sicilian Najdorf: 6.Be2 (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 b5 7.Bf3)

This game was played in a tournament called AUTO-OPEN-3254. After this game my rating went to its peak rating at the time, 2181. The first step towards a loss for my opponent was played by attachui when he or she played 15...Na4. While it was a bad move, it was not like my opponent should have lost because of that move. I then replied with the move 16.b3, which was not the best move and it was only good enough for an equal position. I should have continued by playing 16.Nxf6+ and I could have been on my way to win a pawn.

In order to keep equality, the move 15...Bg5 was required.

Attachui then played 16...Nc5 ending up in some trouble once again. The correct move was 16...Bxd5. The game continued clearly in my favor until I made the sloppy move 24.Nc7. My move seems like a harmless try to trade of pieces when I am up in material, but actually it could have given my opponent some counterplay and with it some compensation for the lost material.

Better options for me were 24.Re3 and 24.Rd2.

Attachui should have answered by playing 24...Rc8, so that when I take on e6, the rook would already be creating pressure on the pawn on c2. Unfortunately for my opponent, attachui chose the more passive move 24...Re7 and the downhill started once more, but this time it did not stop, but instead became worse over time. The position was still not completely lost after attachui's 24th move, but my opponent's 26th move Nb7, the position looked already quite lost for Black. The battle was far from over, the game ended only after my 67th move h6.
