1.b3 e5 2.Bb2 Nc6 3.e3 a6 4.c4 Nf6 5.Nf3 d6 6.d4 e4 7.d5 exf3 8.dxc6 fxg2

Better is 8...bxc6 as the move played hastens White's development

9.Bxg2 b6 10.Nc3 Bf5 11.Nd5 Nxd5 12.Bxd5 Qg5 13.Qd4 Qh5

To prevent White castling long

14.e4 Bg4 15.e5

Now Black starts to get the upper hand. Either 15.Kd2 or 15.Rg1 would maintain White's advantage

15...0–0–0 16.Bxf7 Qh3

16...Qxe5+ is simple and good for Black. My eyes were on a more dynamic line.

17.Bd5 dxe5 18.Qc3 Qh5 19.Rg1 Bc5 20.Qg3 Bf5

I missed 20...Be2 21.a3 Rhf8 22.Rg2 Bf3 23.Rg1 (23.b4 Bxg2 24.bxc5 Bxd5 25.cxd5 Rxd5) 23...Bxd5 winning for Black
