A01 Nimzowitsch-Larsen Opening (1.b3 d5 2.Bb2 Nf6 3.g3)

This is the 23rd game of the 106 blitz games that I played between July 15th, 2016 and August 2nd, 2016. They were the only blitz games I played at Chess.com that year and I have not played blitz there since. I might play blitz there again at some point, but I have not been that interested of doing it for a long time. All of those 106 games were played against the same opponent and at this point the score was 15 - 8 in my favor. First of those 106 games was my first one after an almost two year break from blitz at Chess.com. The below statistics are taken from the LiveBook.
