I almost published a game today that did feature an opening variation that had a different name to it than any that I had previously posted. The problem was that the variation had already been covered here, but under a different name. I only noticed that just before I was publishing that game. This was due to the fact that not all the sources name the same variation with the same name, which is very annoying and very confusing. When I was typing that other post, I did mention in it that I was convinced that I had already covered that variation, but because I could not find the name of the variation among my previous posts, I did not look further. However, before I published that game, I checked from the source material I used when I started doing this blog whether or not it called the variation by a different name and when it turned out that it did, I looked my posts with that name and I found a match. Luckily I had already analysed this game that actually featured a variation that I had not covered before, so that I was able to make the post before this day ended.

The game below was played in a team match called LC VC PRCC. It is played on 38 boards between Limitless Chess and Philippine Rizalian👴Chess Club. I am playing on board 15 for Limitless Chess. The current score looks a bit dire from our point of view, the score is at the moment I type this 9 - 25 in favor of Philippine Rizalian👴Chess Club. I made one small mistake in the game below when I played 11...Na6, it was better to play 11...Nc6. Before that the game was played evenly, after my 11th move my opponent could have had a slight advantage with correct play. 12.Rb1 or 12.Rd1 were moves that give White a small advantage. While the move that six_inchess played leads to a more even position, my inaccurate reply did give another chance for my opponent to be in a slightly favorable position. At first six_inchess was able to maintain the advantage, but then for some weird reason that I can't explain, my opponent played 15.Rd5, which loses the game immediately because I can take the queen with my knight. After I had taken the queen, my opponent resigned as there is no reason to continue the game.

Yesterday I finished reposting all my chess960 games, so all of them can now be viewed with the Chess.com's game viever or replayer or whatever you want to call it. I now only need to go through my chess games and after that the blog is fully ready for https. After that is done, I will likely make it so that viewers of the blog are redirected to the https version of the blog if they use the http version to view the blog. I think it might take the rest of the year to repost all my chess games that I have previously published with Chessbase 12's publish to web functionality, but I try to do that as fast as possible while maintaining my sanity... I have added one mate in two, two mate in three, one mate in four and one mate in five puzzle today.
