B00 Queen's Fianchetto Defence, Nimzowitsch Defense (1.e4 Nc6 2.Nf3 d6 3.d4 Nf6 4.Nc3 Bg4 5.Be2 e6)

If anything, this game that I have analysed today, shows how sometimes I just can't see tactics. For quite a long time now I have done 3 tactical exercises every day and that is the minimum amount but I may need to increase it, in order to improve my vision more. The level at which I see tactics now, is disgraceful at least to me. Only barely over 50% accuracy in solving is not all that good. Well, in truth that is only my accuracy in the tactical trainer at Chess.com. On Chess Tactics Server, I have managed a 85% solving accuracy but as it is based on solving the exercises as fast as possible, my tactical rating there is really bad, since I am old and slow... ;-)
