B08 Pirc Defence: Classical System (1.Nf3 d6 2.e4 Nf6 3.Nc3 g6 4.d4)

Today we shift into a new era of analysis as this game was the first one that I have analysed with the new engine, Stockfish 6 64 BMI2. When I got this new engine I noticed there were different ones to try out, so I googled the one I am using to see what info I could find about it. And luckily there were simple enough answer to be found, so basically if you have the latest Intel's Haswell CPUs in usage, then you should use the version that I use from now on, Stockfish 6 64 BMI2. You might want to try it out but if it crashes use the SSE4.2 version. For more info, please check out Stockfish support page. The reason for using the BMI2 version is that it is apparently the fastest alternative from the versions.

Now for the game below. It was played in a tournament called tedjj's mini-tournament XLIII. As you might notice, the name of the mini-tournament and my opponent have something in common. The reason for it is of course that the creator of the tournament is my opponent in this game, tedjj. This is the only tournament in my memory that I have played correspondence chess so badly that I reside in second to last place. The other tournaments I have played so far have gone much better. I have managed to get only two points in six games in the tournament so far and I think that is clearly the worst start I have had in a correspondence chess tournament. There are 14 games still left for me to play in the tournament, so I still have chances to get closer to the first place. I may have typed some contradictory things in my post yesterday because first I typed that I had finished the list of opponents and then typed that it will updated and improved over time. It is of course not finished and I know there are some things I would like to change there even now but the basic structure I think is in its final stages. Due to the nature of this blog, nothing really stays the same forever. Until I draw my last breath, I keep adding new things and improving things that are not up to the quality that I would like them to be. I have added three mate in ones, one mate in three and one mate in four today. Until tomorrow, my fellow chess enthusiasts and thank you all who have come to spend their time visiting this blog, it is always much appreciated!
