B73 Sicilian Dragon: Classical System without 9.Nb3 (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 g6 7.O-O Bg7 8.Be3 O-O 9.Qd2 Nc6)

B73 Sicilian Dragon: Classical System without 9.Nb3 (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 g6 7.O-O Bg7 8.Be3 O-O 9.Qd2 Nc6)

This was played on the first round of the 1800+ 7 Days tournament. I was on 6th place in the final standings of the group. My opponent, coronaguy, finished on 5th place, one point ahead of me. The tournament's third round is still going on, but to me it is not that interesting since I was already eliminated from the tournament on round one.

For the first 21 moves there were only some small mistakes from both sides and it was only my 22nd move that was a really horrible move. I played 22.Nb4 in the game, which attacked the pawn on a6, but had my opponent just replied with 22...a5, my knight would have needed to move again and maybe I would have traded knights at that point. If that would have indeed happened, my position would have been basically the same that it was after my 21st move, except my knight had disappeared from the board, but my opponent would have moved the pawn to a5 and the rook would have changed its location to c6 while the knight from c6 had also disappeared. Therefore my 22nd move seems to be just waste of time.

The game continued to be played in a clearly favorable way for my opponent with the moves 22...fxe4 23.Qxe4, but then coronaguy played 23...Nxb4, allowing me to get back into the game. The move 23...Ne7 seems to be the preferred choice of Stockfish 8 64 POPCNT at depth 37. The game deciding blunder was seen on the board when I played the incredibly silly move 28.Rfe1.

I obviously was not paying all that much attention to the board when I moved my rook from f1 to e1, because had I looked the whole board before making my move, I would have seen how awful idea moving the rook actually is. Or maybe I thought that the game continuation 28...Rfxf2 29.Qa7+ Bf7 30.Qxf2 Rxf2 31.Kxf2 would be good for me. I had two rooks and a knight against a queen, a bishop and a pawn. If you just count the points that the material should have, the material is actually even. That being said, I was completely lost because I was going to also lose my pawn on b4. I tried my best to blockade the central pawns, but my opponent was able to demonstrate the strength of the pawns and finally after the move 55...Ke3, I decided it was pointless to carry on playing the game, so I resigned.
