E32 Nimzo-Indian: Classical (4.Qc2): 4...0-0 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 O-O 5.a3)

There are over 70 different opening variations featured in this blog already and there still might be more. Every day I keep finding new ones. It has been interesting to go through my old games and see that I have played a lot different stuff over the years that I have mostly forgotten. I still feel that I play mostly the same nonsense over and over again even though there is clear evidence that it is not completely true. Then again it may be my opponents who are the reason for all the different lines, I would play the same thing always if my opponents would do the same.
