C62 Spanish Game: Steinitz Defence (1.e4 e5 2.Nf3 d6 3.d4 exd4 4.Qxd4 Nc6 5.Bb5 Bd7 6.Bxc6 Bxc6 7.Nc3 Nf6 8.Bg5 Be7 9.O-O-O O-O 10.Rhe1 Nd7)

This is the 32nd game in the 100 15 minute games match between two friends. With this win I was able to increase my lead in the match, but the match was not even close to be decided one way or the other. The score was 17 - 15 in my favor after this game. This may be one of the most tactically precise games that I have ever played, at least based on the precision percentage 87, determined by the analysis! If only I could get that in every game... Then my rating would be much higher than it is now.
