D95 Grünfeld: 4.Nf3 Bg7 5.e3 0-0 6.Qb3 (1.Nf3 Nf6 2.d4 g6 3.c4 Bg7 4.Nc3 d5 5.e3 O-O 6.Qb3 e6 7.Bd3)

Today the amount of puzzles featured in this blog went over 200, the current amount is at 203. With this post the amount of different openings featured in this blog goes to 125 and the amount of analysed games is now 194. I will do my very best to offer you more content each day and I am hoping to add from now on more puzzles every day as well as these new games to look at and new opening variations in them as long as there are different ones to go through. I am still playing too many correspondence games and there is little hope of that changing in the near future. The pressure to make moves is always present but so far I have managed not to lose on time. The game below is against the same opponent that I shared a game with you all yesterday, this time I lost in a game where I did a couple of really bad moves.
