A85 Dutch Defence: 2.c4 Nf6 3.Nc3 (1.c4 f5 2.d4 Nf6 3.Nf3 d6 4.Nc3 c6 5.g3)

Between July 15th, 2016 and August 2nd, 2016 I played 106 5 minute blitz games against a friend of mine in preparation for the Finnish Team Blitz Championships that was played at Helsinki between August 6th and August 7th, 2016. This was the 21st game and after this game the score was in my favor 13 - 8.

I only found this old game when I searched reference games where both players were rated over 2500 and reached the position after 5.g3.
