A00 Irregular Openings (1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 4.e3 Nc6 5.Bb2 O-O)

A00 Irregular Openings (1.b4 e5 2.Bb2 Bxb4 3.Bxe5 Nf6 4.e3 Nc6 5.Bb2 O-O)

This was played on the fifth round of the third division, group 4 team match between SalSK 3 and NurmSK. I played on board 5 for SalSK 3 in this match that was played on five boards. I was unfortunately the only player in our team who was able to win his game, so we ended up losing the match with a score of 1 - 2. Draws are not counted for the final score. The first position where the game started to go towards a loss for one of the players was seen when I played 12...Qh6.

My opponent found the strongest reply 13.d5 and then I played the move that could have lost the game, 13...Nb8. I should have moved my knight to e5 instead of the passive square b8, but even then I would have been in a lot of trouble. The reason why moving the knight to b8 was so bad is that it disrupted the connection of the rooks, which my opponent could have taken advantage of with the move 14.Qa4. The queen would have attacked both the bishop and the rook and the game would have likely ended there. My opponent chose to play 14.Nd4 and missed the chance to win the game. The next horrible move was played on move 17 by my opponent. He chose to move the knight to f5.

Had I continued with 17...Ng5, my opponent would have been on his way towards a loss. I missed my chance, like I had do so many times before and have done since. I played 17...f6, apparently to protect the pawn on g7. Honestly I can't remember what went through my head as I played this game, because it was played so long time ago, but since I usually play a bit too passively, it is likely the reason why I played 17...f6. My move was met by another blunder 18.Qf4, which allowed me to seize the winning advantage with the reply 18...Ndc5. It did not last long because already after 19.Rd1 I played Nb3 and my chances to win the game were greatly diminished. I was the next player to make a huge blunder and it saw the light of day when I played 22...Qh5??

The move that would have destroyed me was 23.Nxg7 and I think I would have resigned soon. My opponent played 23.Nd4 instead and he went from having a winning advantage into being clearly worse. I then took the pawn from c4, which was not the strongest idea. The moves 23...Qe5 and the odd looking 23...Re4 were better choices for me. The game continued to be slightly favorable for me, until my opponent played 27.Qg4.

The strongest move for me would have been 27...f5, but I played the sloppy 27...Re7 instead and lost some of my advantage once again. Some terrible moves later we reached the position after 31...Qb3, at which point my opponent made the horrible choice of moving the rook to e4. The reason why it is so bad is that I could have played 32...f5 and I would have been on my way to an easy win.

I was not able to find that move unfortunately and played the disaster of a move 32...b5 instead, which could have lost the game due to the reply 33.Nc5. Luckily for me, my opponent also missed his chance and played the move 33.f5 in the game. The game deciding mistake was seen when my opponent played 34.Nd4??

The move was so obviously bad that even I was able to take advantage of it and played 34...Rxe4 and no matter how it is answered, the game is clearly lost for White because the White queen is overloaded. My opponent continued playing the game until I played 49...Qxg6 after which he resigned.
