This might very well be the only game in this blog not to have a reference game included in the notation. This is because when I used my normal settings to analyse this game, the program did not commentate the first 18 moves of the game in any way. As there was already the move that lost me the game included I found it strange. There was only one reference game apparently for this game and apparently as the program uses this reference database for checking the opening, it may have mistakenly thought that it was something that can be played. I know that the way I have analysed games is not perfect but never thought that this kind of problem could exist. After trying to analyse this game twice with my normal settings, the second try was mainly intended to check if I had mistakenly put the last move to be checked by the program something other than move number one. As I got the same result as with my first try, I left the opening reference out of the analysis, so that it would not see if the moves were previously played from the reference database. After I did that I got in my opinion better analysis.

The game below was played in a tournament called 2014 September Octet I 1700-1800. This is a small eight player tournament where it is all versus all with both colors. The winner has already been decided and that was my opponent in this game, AttilaTheHorn. He won all but one game in the tournament and even that was a draw, so he was undefeated! I can get a second place finish in case I win both of my games that are still in progress. Well, I can get the second place also if I get a win and a draw from the last two games. Maybe the most important moment of the game was seen after the move 14...b5.

I did move my knight, but unfortunately to a very passive square a2. I probably thought about the move 15.Nd5 in a superficial way and thought it to be unplayable. After my 15th move it was all downhill for me, and I resigned after 19...b3.
