B00 Queen's Fianchetto Defence, Nimzowitsch Defence (1.e4 b6 2.d4 Bb7 3.Nc3 g6 4.Nf3 Bg7 5.Bc4)

This is a previously shared game with a more detailed commentary. The first position of interest came already after my 6th move O-O. It can be seen in the diagram below. The move that my opponent chose to play was 6...Qd7. The move does not really make much sense to me. The queen does not really have good squares to which it could go from d7 and it might make the development of the knight from b8 more difficult. The game continued with the moves 7.Re1 h6 8.Bf4 and then my opponent blundered with the move 8...a6. The move a6 is a waste of time, even though it controls b5, it does not answer to the requirements of the position. It would have been a better idea to move the e-pawn from e7 to e6 and maybe prepare castling to the kingside.

I responded correctly with 9.e5! Since I had mostly developed my pieces and Ahmedegyptair's king was still in the center, it seemed logical to try and open the center. After my 9th move I should have had a winning advantage, according to Stockfish 8 64 POPCNT. All went well for me, until we reached the next diagram position. I had two options, either to take the bishop with the queen or with the pawn and I chose poorly. One of the choices kept the winning advantage and the other lost almost all of the advantage, so that the position was only slightly better for me.

The next important moment in the game happened when we reached the position seen in the diagram below. Ahmedegyptair moved the knight from c6 to b4, which was a horrible mistake and the start of the downfall for my opponent, from which he was not able to make a comeback from.

This paragraph was typed when I originally shared this game, therefore the information in there is out of date. This game was played at Chess.com in a team match called OCD BIG XMAS MATCH. This is a 76 board match between Obsessive Chess Disorder!! and ♞KNIGHTS of the REALM♞. I am playing board 15 in this match for the Obsessive Chess Disorder!! and we are currently leading the match 69,5 - 57,5. So far the match is going well for us, I hope it continues to do so in the remaining games aswell. This match started December 6th 2014 and because of the one simultaneous game setting in this match, my second game against Ahmedegyptair started only after this ended yesterday.
