B00 Queen's Fianchetto Defence, Nimzowitsch Defence (1.e4 b6 2.d4 e6 3.Nf3 Bb7 4.Bd3 c5 5.c3 cxd4 6.cxd4 Nf6 7.Qe2 Bb4+)

The more detailed look at my previously shared games continues with this post. It really annoys me that I could not do the original post like this, so that I would have only needed to change the name of the opening used in the game and not do most of the work from scratch. The first position that I like to show can be seen in the diagram below. It is taken after my 9th move O-O. In this position my opponent played 9...d6. It is a huge blunder and could have been the losing move. I was not aware of my possibilities and played just a normal developing move 10.Nc3. The move that I should have played was 10.d5! It seems so obvious now, but apparently I was not paying attention to the situation on the board and just played a move that seemed not to lose...

My move was okay, but had I played 10.d5, I would have had a winning advantage. Alfito2012 replied with the move 10...O-O, which could have been a problem for my opponent, but because I played 11.a3 instead of the correct move 11.e5, the game continued more evenly than it should have. The next diagram shows the position after 23...Bxd5. This was the position in which I played my losing move 24.Bxd6?? It was replied with the crushing move 24...Nxe4 and the game was quickly over.

This paragraph is taken from the original post and therefore it is in some ways out of date. This game is from a team match called Mount Doom. The match is played on 30 boards between Lord Of The Rings and Team Latinoamérica. I am playing on board 3 for Lord Of The Rings, my other game against alfito2012 is still in progress. This has been quite evenly played match as the current score 23.5 - 22.5 demonstrates. The score is in favor of Lord Of The Rings. We still need seven points to secure the win and maybe I can help in that effort, I certainly would like to be able to do so. However, due to my recent game results, I am not at all sure what will happen in any of my games as it would seem to me that I can mess up almost every game at this point in time.
