C52 Evans Gambit Accepted: 5.c3 Ba5 (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 exd4 7.O-O dxc3 8.Qb3 Qf6)

This is the 10th game I have played at ChessRex and it is my first and so far the only loss on the site. I have played both chess and chess960 games there and this is the sixth chess game from there. It is also my latest chess game from ChessRex. In addition to these six chess games, I have so far played seven chess960 games there. In chess960 I am at this moment undefeated there, but I am sure that day will come when someone outplays me in this chess variant. It has happened many times on other sites and only time will tell when it happens at ChessRex. Both players had seven days to use for each of their moves and I probably should have used more of it during this game in order to get a better result. This game started January 7th 2016 and finished on January 30th 2016.

From time to time I ran into opening variations that I think I have already covered, but when I look at what I have posted, there is no evidence of an earlier occasion where that opening variation would have been posted. One of the times this has happened was with this particular opening. Sometimes I briefly think that I have just accidently deleted the post that contained the variation I thought that I had already posted, but maybe the more realistic reason is a false memory of such a post. Those false memories probably are due the fact that I search for other similar opening variations for each game I post and those opening variations have appeared in the analysis, but are not the actual variations played in the games.

Despite from the name of the opening, this actually is a reasonable way to play as the position is evaluated about even at least according to Stockfish. The first disturbance in the balance comes when I play 16...Nf5 which is a really bad move. This move did not lose the game even though it could have been the reason for the loss if dominick1952 would have replied correctly. He made a horrible move instead that could have brought me back into the game, but I blundered a second time in a row. This time my opponent was able to play well enough that he did not allow me to get back into the game anymore. I was only able to make dominick1952's job easier in the remaining moves and I had to accept defeat after I saw the move 23.Qh3. Until Monday, my fellow chess and chess960 enthusiasts!
