After this post, I have gone through only 183 games that were previously shared in the blog and changed the names of the openings that were played in those games. In addition to that I have added commentary that was not previously seen attached to the games, when it has been required. This means that if I continue the changes to the old posts, it will likely take me years to go through all of the games previously shared in the blog, because there was about 1500 chess games shared before I started doing these changes... I have not been doing any content for my YouTube channel in months, because I am not sure what I want to do about it. Maybe I will start doing Chess960 videos again, so that I would at least do some content for that chess variant, because it will likely take a very long time for me to share any Chess960 games in this blog.

This was played in a team match called Russia Central Federal District vs DORU-66 & HIS BEST FRIENDS. The match was played on 78 boards and I played on board 21 for DORU-66 & HIS BEST FRIENDS. I was not able to help the team with any points as I lost both of my games against igrinyuk. The match ended with a score of 82.5 - 73.5 in favor of Russia Central Federal District. I did play quite well in the game below, until I played 27.c4, which I played because I thought that I could just put my queen and both rooks on the d-file and push the pawn on c5 and win some material... I can't really believe that I missed my opponent's obvious reply to 27.c4, which was 27...Ne7 and after that I was clearly worse and I could not get back into the game in the remainder of the game.

At depth 46, Stockfish 8 64 POPCNT thinks that moves like 27.Ne1, 27.R5d5 and 27.R5d3, for instance keep the equality of the position.

While my path towards a loss started with my 27th move, I was not completely lost until I played 30.Rdc1. The severity of my mistake came clear when opponent responded with the move 30...d5. I could not avoid losing more material after that move. It did not stop me from continuing the game, I prolonged my suffering up to the move 39...Qd1.
