A07 Réti Opening: New York and Capablanca Systems (1.g3 e5 2.Bg2 Nf6 3.d3 d5 4.Nc3 Be6 5.Nf3 Nc6 6.O-O Be7 7.Bg5 O-O)

At Chess.com there is a tournament in progress called "EXPECT NO MERCY - NAZARETH TOUR!!!", from which this game is taken. This is from the first round of the tournament, which is nearly complete, there is only one game left to finish, before the second round can begin. I managed to win my group, which means I will take part on round 2, the only player from my group that will do so, since only the winner advances from one round to another. My opponent in the game below, csabiu, was on second place in the final standings of group 7 with 6 points, half a point behind me. Starting with the move 13.Kh1, csabiu's position went downhill for two consecutive moves.

13.Bxh3 is the correct move according to the engine at depth 32.

I replied with 13...Bxh4 because it ruined the pawn structure on the kingside and I thought that is worth of giving up the bishop pair. I seem to have been correct the judgement since Stockfish also likes the move. Csabiu's next move 14.gxh4 was the second mistake in a row, it was better to take on h3 first. In the game continuation I should have then played 14...Bxg2+, but instead I went for the move 14...Qg4, which threatened mate, but it was easily dealt with 15.Rg1. The game continued in a roughly even manner until my opponent played 19.Rg2.

Better moves for csabiu were 19.Qf1 and 19.cxd4.

With the move played in the game my opponent went from a slightly favorable position to one where csabiu were clearly worse. For example, the game might have continued 19...dxc3 20.Bxc3 Rad8 and the weak central pawns should put csabiu on the defensive. I went for the wrong move order unfortunately, I played 19...Rad8, which would have allowed my opponent to take on d4 and the position would have been equal. Csabiu moved the knight to g1 on move 20 instead, which was perhaps the worst move of the game up to that point because I could have been able to get a winning advantage starting with 20...dxc3. I do not know why I did not play it, even though I had clearly planned on doing it after Rad8. There really was no threat along the g-file, so I can't remember my reasoning why I played 20...Kh8. It was an okay move and I should be in the favorable side of the board, but it would have made my job of winning the game much easier, had I just taken on c3. Because I allowed my opponent some breathing room, csabiu was able to play 21.Nf3 and attack my queen. I moved the queen to h3 thinking that I can use the diagonal c8-h3 for retreating the queen safely. It was not the right idea, however, I should have just moved the queen to h5.

22.cxd4 was the only move that would have kept my opponent in the game.

Csabiu's reply 22.Rg3 was first of two consecutive bad moves made by my opponent. I then had two good squares for the queen, h5 and e6, I chose the latter. It was answered by the terrible move 23.Qf1 and I was given another chance to get a winning advantage starting with 23...dxc3. Unfortunately I was too defensively minded once again and overprotected the g7 pawn with my rook. Even after that my position should be quite good when compared to that of my opponent. Everything went on more or less my way after that up to the move 32.Nh4.

Strong moves for me were 32...Rxe4 and 32...Qd7, according to Stockfish 8 64 POPCNT at depth 32.

For some reason I thought it would be a good idea to play 32...Qg5 and I completely missed the annoyance factor caused by 33.Ng6+. It would have won the pawn back and the position would have been evenly fought, had my opponent just played 34.Nxf4 after I moved my king to g8. I guess csabiu thought that he or she can actually win the game in the game continuation 34.Rxe8+ Rxe8 35.Qd5+ and it would have been true had I not been able to just take the queen on d5 with its counterpart. In fact the move 34.Rxe8+ should have meant a loss for csabiu, but I was able to mess up this game with two consecutive bad moves, first one being 36...Re2 and the second 37...Rd2.

My path to victory would have started with either 36...Re1+ or 36...Ng5.

The game ended to a perpetual check that I allowed when I played 38...Rxd3.
