C99 Closed Spanish Game: Chigorin Defence, 11.d4 Qc7 12.Nbd2 cxd4 (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 d6 8.c3 O-O 9.h3 Na5 10.Bc2 c5 11.d4 cxd4 12.cxd4 Qc7 13.Nbd2 Nc6)

So, this post has some out of date information because it was typed when I originally shared this game. This is the final fourth round game from the first WORLD OPEN RAPID tournament that I have played. In this tournament everything worked like a charm and I won the tournament undefeated with a score of 3,5 out of 4. I think I have played seven tournaments now at FIDE Online Arena and this still remains the only victory I have. It may still be one more than I would have originally thought that I could get. The opening in this one does differ from the theoretical move order and I am not sure if I should have played 13.Nc3 instead of the game continuation. I think I have tried out that Nc3 at some point in these 15 minute tournament games but I can't even remember what the result was. I played the move 13.Nbd2 because I knew that I end up in an opening variation that I had not previously covered in this blog. Since I started doing this blog, I have started to remember the ECO codes for some openings and even the names of them, which I guess can be seen at least as a progress in my chess skills. I am currently very close of reseting the game requirement for the Arena International Master as I have since my decent start managed to destroy my rating and it has dropped over 100 points in a few tournaments. Currently my monitored elo in rapid is 1711, which means that I may be one loss away of reseting that game counter which does annoy me. I have faced some bad luck in facing underrated people and losing against them. I have decided that if I am going to get one title from these games, it will be at least the Arena International Master title. If I mess up my first go at it and would only be allowed to get Arena FIDE Master title after those 50 games have passed, I won't claim that title but wait until I can get the AIM title. It may mean a very long wait if I keep playing as badly as I have before... Until tomorrow, my fellow chess enthusiasts.

The first sign of trouble for andrei2015 was seen when my opponent played 14...Nb4 in the position below. When I played 14.Nf1, I probably did not see the idea behind the moves 14...Nxd4 and 14...exd4. I could not have taken back twice on d4 because I would have lost the bishop on c2. After the move andrei2015 played in the game, I should be close to a clear advantage.

The game continued with the moves 15.Bb3 a5 16.a3. Then andrei2015 played 16...Na6, after which my opponent was starting to be in clear trouble. Or rather would have been in clear trouble, had I played a good move in reply, but I did not. I played 17.Qd3, which allowed andrei2015 back into the game. My best option would have been the move 17.Bg5. I got another chance for the clear advantage when, in the position below, andrei2015 played 18...Rfb8.

I replied with the move 19.Nd5 and it was good enough to take an advantage that the Stockfish 8 64 POPCNT roughly estimates to be 1.4 pawns. The game continued with the moves 19...Nxd5 20.Bxd5. After my 20th move andrei2015 made the biggest blunder of the game so far by playing 20...Ra7. The only move that could have kept my opponent from ending up being in a completely lost position was 20...Bc6. I answered to the move played in the game by moving my bishop to g5, which was not the best possible idea. It was better to play the bishop to e3 on move 21. Then andrei2015 played another bad move, 21...Be8. With that move andrei2015 ended up in a lost position once again. I was not playing accurately and a few moves later, when I played 27.Qg5 in the next position, I had lost all of my advantage.

The move that I should have played according to Stockfish is 27.Rxc7. With that move I could have remained on the clearly better side of the board. In the remainder of the game I got maybe one more chance to a clear advantage when andrei2015 played 40...Rxe4 in the next position. That being said, there might have been one other chance after my opponent played 31...Nd3, but that is not as clear as the one after 40...Rxe4.

I did not find the strongest reply 41.Nd3 and instead played 41.Nxg6. Even after that move I should be clearly better, at least according to Stockfish, but to my eyes it does not seem so easy. Actually the position seems to be quite close to a draw, but what do I know. The rest of the game went clearly in my favor, apart from the position after 42.Rb5, which was about even. Even if I may have an advantage in the last position of the game, I doubt that I could have won the game.
