The chess player, graviton, at the online site FICS, is not a Jerome Gambit afficionado, but he can turn Jerome-ish when he is provoked. He will take offense at the Blackburne Shilling Gambit. He will also react sharply to an ill-advised ...Na5. The following game is anexample.
graviton - porttela
10 0 blitz, FICS, 2019
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O
Black can be excused if he believed that his opponent was planning on a quiet game. Why not go along with the first player, and simply work to gain the "minor advantage"?
4...Na5
Ill advised. Expecting 5.Bb3, to be met with 5...Nxb3, he overlooked the straight-forward 5.Nxe5, which would have been a fine reply. He also overlooked White's actual response.
5.Bxf7+ Kxf7 6.Nxe5+ Ke6
The King would have been safer at f8.
7.d4
The next time around, graviton might try the still-unplayed (according to The Database) 7.Qg4+ which would have been even more punishing: 7...Kxe5 (7...Kd6 or 7...Ke7 would lose the Queen, while 7...Kf6 would lead to mate) 8.d4+ Kd6 (other moves would lead to loss of Queen or mate) 9.dxc5+ Kc6 10.e5, when the Knight at a5 will soon fall and Black's King is still unsafe.
7...Bd6
Allows checkmate. Black had to play 7...Nf6 and try to hang on.
8.Qg4+ Ke7 9.Bg5+
White has figured out his way to a win. It would be a bit academic to point out 9.Qxg7+ Ke6 10.d5#.
9...Nf6 10.Bxf6+ gxf6 11.Qg7+ Ke6 12.Qf7 checkmate
