E39 Nimzo-Indian: Classical, 4...c5 5.dxc5 O-O (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5 5.dxc5 Bxc5 6.Nf3 O-O 7.Bg5 Be7)

This was played in a team match called Vikings know no limits. It was being played on 69 boards between Great Viking Warriors and Limitless Chess. I played on board 22 for Limitless Chess and lost both of my games. I tried to play as well as I can, but Raho1967 played better chess than me. Well, now that I looked the match results on August 24th, 2017, I noticed that my opponent's account has been closed due to violating the fair play policy.

The game went reasonably well for me until it came to my 13th move. The position below is the one in which I played 13...Ne5, the first step towards a loss. Had I played 13...Bd7, I might have been able to hold on for a draw with accurate play.

My final mistake was to play 21...axb5, after that there was no coming back for me. You can see the position when I played that move below this paragraph.

The rest of the game only featured my futile attempt to change the way the game was going.
