B95 Sicilian Najdorf: 6.Bg5 e6, unusual White 7th moves (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 e6 7.O-O Qc7 8.Bg5 Be7)

The game below was played in a team match called OCD vs THE POWER OF CHESS: The Fair Match. The match was played on 53 boards between Obsessive Chess Disorder and THE POWER OF CHESS. I played on board 8 for OCD and managed to win both of my games, though it was by no means easy, I was actually losing the game below, but then my opponent stepped into a forced mate. If there is luck in chess, I experienced it during this game. The match ended with a score 45.5 - 60.5 is in favor of THE POWER OF CHESS. For the first 16 moves were played rather evenly, but then I made a poor choice with the move 17.exd5. Taking on d5 only improves my opponent's pieces and it would have been a better idea to play e5 and keep the light-squared bishop on b7 hitting the same colored pawn on d5. In the game continuation my opponent's pieces are much more active than mine.

In order to maintain equality, I had to play 17.e5.

The game continued with the moves 17...Nfxd5 18.Nxd5 and then my opponent blocked the scope of the light-squared bishop once again with the knight with the move 18...Nxd5. It removed some of the possibilities that my opponent would have had, had Judoman played the much better move 18...Bxd5. Taking with the bishop would have generated some pressure towards g2, but more importantly it would have also made the pawn on c2 overloaded and I would have needed to react to it, giving my opponent the initiative. The game was played relatively well by both players after that until I made the very foolish move 31.h3??

I should have played 31.Nf3, which would have given my bishop more room to move if f4 is played at some point.

Playing 31.h3 was bad because the square g3 was weakened, so that my opponent was able to play 31...Bg3. At that moment I was quite lost, but I continued to fight on and it could have been rewarded on move 44 when my opponent blundered with the move Rf5. My path towards a draw could have started with the move 45.Rxf5, but I played the much more risky 45.Rd7, which seemed to me a more promising option.

The move that seems to end my counterplay possibilities quite effectively is 44...Qg3+.

Judoman replied with 45...R5f7 and I could have traded rooks again and the game might have been going towards a drawn again. I declined the trade of rooks once again and placed my rook to d6, which attacked the pawn on h6. My plan worked out, because it enabled the possibility for my opponent to blunder and blunder Judoman did.

The queen check on g3 was still the best idea on move 46.

Judoman protected the pawn by placing the king to h7, which threw the game away. With perfect play it would have been a forced mate in maybe eleven moves, but due to some inaccurate moves, the end became quicker and my opponent resigned after my 49th move Rg7+, which was the first move in a forced mate in three.
