A53 Old Indian Defence without Nf3 (1.e4 d6 2.d4 c6 3.c4 Qc7 4.Nc3 e5 5.Nf3 Bg4 6.Be2 Be7 7.O-O Nf6 8.Be3 Nbd7)

The game below was played in the fifth and final round of the WORLD OPEN RAPID tournament that was held at the FIDE Online Arena on April 13th 2015. This is also the last tournament game that I have played at FOA. Maybe I will start playing tournament games there again at some point, but for now I do not have the time to do that. I would like to activate myself there again but at the moment it would seem that I have too many other things to do, but maybe I can get a game or two played next week. I finished this tournament with three wins and two losses, so this was yet again only a mediocre performance from me. This game featured many mistakes and both players had couple of opportunities to win. The move I like the most is 37.Bxg7! because I was able to play that nice move in a difficult position.
