It is time for me to retire from typing a blog about chess and its variants

It is time for me to retire from typing a blog about chess and its variants

When I started doing this blog on July 15th, 2014, my goal was to go analyze all my games with an engine and name the posts according to the opening played in the games that appear in the post. This meant that I needed to update older posts whenever I discovered other games in a certain opening that I had already covered in the blog. It was also a way for me to force myself to go through my games, which I would not have normally done. Later I started to also add Chess960 games to the blog when I found a publishing tool that was able to that. While I have been able to reach my goal partly, I have in the past made quite a few mistakes in the posts that you may or may not have noticed. When I have noticed a mistake, I have corrected it the best I way can. For quite a long time now I have been doing changes to the blog, but it does seem like a never ending task and I have not been able to get back to posting consistently new games both from chess and Chess960. It would likely take several more months for me to complete the changes and I do not really think that it would the best use of my time.

Well, I should go now for the actual reason why I named the post the way I did. Lately I have started to think of ways how to best use my time and what I want to do in the future. Typing this blog has been something I have done somewhat regularly for nearly four years and especially recently it has become more of an annoyance to me than anything else. Therefore I think it is time to start using the time I spent doing this blog to other things. I have not been all that passionate about chess or Chess960 for quite some time now and I think I can't type about them in all that interesting way. Continuing to make posts for this blog is something I do not think would be beneficial to me or to other people anymore. I have also turned off the ads, as you may have noticed. It is probably a permanent change. At this point I would like to thank all of the people who have visited my blog or viewed my videos at YouTube or made comments in any of my posts or subscribed, it is much appreciated. I probably won't delete the blog, it will be here in case I ever decide to come back, but at the moment it is very unlikely thing to happen.

B22 Sicilian: 2.c3 (1.e4 g6 2.d4 c5 3.c3)

B22 Sicilian: 2.c3 (1.e4 g6 2.d4 c5 3.c3)

This game was played at Queen Alice Internet Chess Club and it was played between August 14th, 2014 and September 20th, 2014. With this win my rating at the site increased from 2118 to 2122. I am currently at my peak rating there, which is 2214. I have not played there for over a year now, my last game there ended on March 14th, 2017. While I have not played there for a quite a long time, I might at one point return there.

B27 Sicilian: 2.Nf3, unusual Black 2nd moves (1.e4 g6 2.d4 Bg7 3.Nf3 c6 4.c4 d5 5.cxd5 cxd5 6.e5)

B27 Sicilian: 2.Nf3, unusual Black 2nd moves (1.e4 g6 2.d4 Bg7 3.Nf3 c6 4.c4 d5 5.cxd5 cxd5 6.e5)

This one was played in the second round of the WORLD OPEN RAPID tournament that was held at the FIDE Online Arena on March 17th 2015. After two rounds I had won one and lost one. My opponent did not make as many mistakes as I did, so forgeforever did deserve to win this game. I mean I did not even take the free pawn that was offered to me in the opening, I can't believe I missed 12.Nxd5. Hmmm, maybe I was afraid of 12...e6 and I am actually not sure how to reply to that move even now. I checked the position after typing the previous sentence and it seems if 12...e6, then 13.Bc7 saves White's pieces and the pawn has been won without any problems.

A45 Trompowsky Attack (1.d4 Nf6 2.Bg5 e6 3.e4 Be7 4.e5 Nd5 5.Bxe7 Qxe7 6.c4)

A45 Trompowsky Attack (1.d4 Nf6 2.Bg5 e6 3.e4 Be7 4.e5 Nd5 5.Bxe7 Qxe7 6.c4)

The game below was played at GameKnot in paweljaniak's mini-tournament I. After this game my opponent, muek54, withdrew from the tournament and our other game was never played. It was the only game that muek54 did not play in this mini-tournament. I was on second place in the final standings with 8.5 points. Muek54 was able to get 4 points and finished 5th in the tournament. The winner of the mini-tournament will be paweljaniak (2149), who won all but one game. That one game he lost to muek54 interestingly enough. This win also enabled me to get to my peak rating at the time at GameKnot, which was 1794. My current rating is 1832 there. This game was also my 100th game there.

The first mistake of the game was played by my opponent on move 20, before that there were some inaccuracies, but nothing that shifted the advantage in favor of either player in a major way. 20.exf6 was a much better alternative. Muek54 played the final mistake of the game on move 30, after which the game was completely lost for him.

C01 French: Exchange Variation (1.d4 Nf6 2.Bg5 e6 3.e4 Be7 4.Nc3 d5 5.exd5 exd5)

The game below was played in a match that was played between Fighting Warriors and * The WOLF *. The match is called open Challenge # 122. This was played on 34 boards and I played on board 3 for * The WOLF *. The match ended with a score 23 - 45 in favor of * The WOLF *! There was quite a lot of timeouts in this match and we won on boards 1, 7, 9, 11, 12, 13, 17, 20, 23 and 30 both games on timeouts. And on five boards we won one of the games on timeouts, so we won 25 games on timeouts... In a match of this size, it is a huge amount of games basically forfeited only because players did not make their moves on time. We only lost one game due to a timeout, so we had more fighting spirit and wanted to win more than our opponent.
