Boris - NN

2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.f4 g6

A mistake. Not well thought through. When in doubt, attack the Queen.

9.Qxe5+ Kc6 10.d4 

Yes, yes, Boris knows that the Rook at h8 is en prise. Black's 8th move suggested that it was time to focus on checkmate. 

10...Bb4+ 

Black stumbles upon his best chance, when he makes his next move. He had some crazy chances right now with 10...Qh4+ 11.g3 Qh5. What follows (according to Stockfish 11) is funny: 12.f5 (threatening mate; 15.Qxh5 gxh5 16.dxc5 works, too) Bd6 13.d5+ Kb6 when 14.Qxh8?! would allow Black to hunt the White King after 14...Bxg3+ 15.Kd2 Bf4+ 16.Kd3 Qf3+ 17.Kc4 Ka6 18.Bxf4 b5+ 19.Kd4 Qxf4 20.Rd1 c5+. White would still objectively be better, but why seek out that pain? Instead, 14.Qc3 Ka6 15.Qd3+ followed by developing the Queenside and pressing the attack against the enemy King.

11.c3 Qh4+ 12.g3 Bxc3+ 13.Nxc3 Qh5 14.f5 b5 15.Qd5+ Kb6 16.Qxb5 checkmate
