A33 Symmetrical English: 2.Nf3 Nf6 3.d4 cxd4 4.Nxd4 e6 5.Nc3 Nc6 (1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.Nc3 cxd4 5.Nxd4 Nc6 6.Ndb5)

It did take today quite a long time to get things going but I still managed to get this post done today and maintain my daily blog posting pace. Tomorrow might be similar day as today but I will try to get a post done by the end of the day. While I went through my database and tried to figure out what openings were played in the games, I noticed I had made a mistake in one of my earlier posts. I have used the same source of checking these openings since I started doing this blog and I have occasionally noticed that it does not contain all of the different variations. The mistake I made was due to the fact that the opening variation used in all of the games in that post was not covered in the source material I had been using. From now on I think I need to check the accuracy of these variations at Chess.com as I would like to think that they have all those variations correctly there. The post I renamed and modified the pgn-files there was called previously B40 Sicilian Defense: French Variation, it was quite close to being correct but it missed one move and the rest of the name of the opening variation. That post is now called B40 Sicilian Defense: French Variation. Westerinen Attack. That opening bears the name of the legendary Finnish Grandmaster Heikki Westerinen. I have been honored to be playing on the same team as him twice, he played on board one and I played on board eight in two team matches in 2011. Actually I had been known to this variation maybe some years ago when I watched one of the Attack with LarryC videos at ICC but as I could not confirm the name in my source of the opening names, I had not used the name. Well, it is sometimes hard to determine the name of some opening line especially when the moves are out of order, like in the game below. The move order that you see in theory is 1.c4 c5 2.Nf3 Nf6 3.d4 cxd4 4.Nxd4 e6 5.Nc3 Nc6.

Today I have added four mate in ones and one mate in three. Thank you all who have come to see this blog and special thank you to those who have followed me on Google+ and those who have made comments on my posts, it is much appreciated!
