E38 Nimzo-Indian: Classical, 4...c5 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5)

E38 Nimzo-Indian: Classical, 4...c5 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5)

This was the third game in a row that I played against Nestor Oprysk, the two games before this one I was able to win. We played these games close to midnight and this was the only one of the three games that was played on a different day. This is also currently my latest game from the FIDE Online Arena. I had a very good start for this game, I had strong enough advantage that should have meant a third win against Nestor. However, I am able to mess up almost any good game and my technique starts to prove faulty on move 21. After my move 21...Rc8 both players play some horrible moves, but I regain my winning advantage shortly after the blunder 23.Qa3. I stumble near the finish line with 27...gxh5 and after that I am just lost, but I continued the game a couple of moves longer.

Both players played reasonable moves only up to my 4th move c5. In that position my opponent blundered with the move 5.Bg5. In the next diagram is shown the position in which Nestor Oprysk played 5.Bg5?? Allowing me to reply with 5...cxd4 and I should have been on my merry way to victory.

Both 5.dxc5 and 5.Nf3 seem like better options for White.

Like I typed above, up to move 21...Rc8 that I played in the diagram position below, I pretty much threw my win away. I completely missed the brilliant move 22.Rxh7, which would have been the material equalizing move. I could not have taken the rook because of the mate that would soon follow 23.Rh4+ Kg8 and either 24.Rh8# or 24.Qh8# finishes the game.

I should have played 21...e5, but 21...h5, 21...f5 and 21...Qe7 were also good enough to keep my winning advantage.

The game continued with the horrible 22.h3 and I got another opportunity to play e5 and close the long diagonal and prevent the move Rxh7 from working. I just kept playing on the queenside, not at all looking what my opponent could do on the kingside. Luckily for me, my opponent did not see the golden opportunity either and just played 23.Qa3, attacking the pawns on a7 and b5. Unfortunately for Nestor Oprysk, the queen move also took the opportunity to play Rxh7 away from my opponent. After that I was going towards a win once again. Until I played 27...gxh5 in the next diagram position that is.

In this last turning point of the game I should have played either 27...d4 or 27...Qe5. 27...Rb5 was also a good option.

From a winning position I went to a losing position, out of which I could not get out of. Couple of moves later I accepted my loss, because I faced a mate that I could not avoid.
