E43 Nimzo-Indian: Rubinstein: 4...b6 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 b6 5.Nf3)

In this rare occasion I am able to publish two games at once in an opening variation I have not previously covered. This first game was played in the 2014 August Grand Seven Fourteen II tournament. The tournament started August 11th 2014 and it is still ongoing. Only two players are still in the fight for the first place and I am one of them. This 21 player tournament features players from beginners to more advanced players and everything in between. Even though I am currently the highest rated player in this tournament, it may change quite quickly to something else as people play lot of simultaneous games and ratings are calculated immediately after the games end.

Even though missing one tournament in the FIDE Online Arena does slow my game requirement for the title a bit, I still think it is wise for me to not play today as I am quite tired. I hope that I am more rested tomorrow and can play well so that I could get my monitored elo up a bit again. It is still too close to 1700 and under no circumstances should I allow it to drop below it. That would mean that I would need another 50 rapid games for the title as the counter would reset at that point. The fact that I am tired is not the only reason that I should playing today as I still need to move in lot of my correspondence games today and it would be nice to go to sleep a bit earlier than yesterday. I have added one mate in one, two mate in five, one mate in seven and one mate in ten today.
