D60 Queen's Gambit Declined: Classical: Unusual White 7th moves (1.Nf3 d5 2.d4 Nf6 3.c4 e6 4.Nc3 Be7 5.Bg5 O-O 6.e3 c6 7.Bd3 h6 8.Bh4 Nbd7 9.O-O)

D60 Queen's Gambit Declined: Classical: Unusual White 7th moves (1.Nf3 d5 2.d4 Nf6 3.c4 e6 4.Nc3 Be7 5.Bg5 O-O 6.e3 c6 7.Bd3 h6 8.Bh4 Nbd7 9.O-O)

This is the 33rd blitz game in a series of 106 games that I played in 2016 at Chess.com against a friend of mine. After this game, the score was 22.5 - 10.5 in my favor. Based on the tactical precision percentages in these blitz games, I have been able to be more alert tactically than my opponent more often than not, which reflects the outcome of the games quite nicely. I have been thinking of creating databases based on the precision percentages, so I would have a databases where my precision has been less than 10%, less than 20% and so on. I am interested in statistics like that and I think it would help me to see how many really good or bad games I have played.
