ndrwgen, with White in the following miniature, is familiar with the Jerome Gambit - in fact, he has 165 games in The Database.
ndrwgn - abogatyrev
5 0 blitz, FICS, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.O-O
A move in the Two Knights that has "more going for it than is generally realized" as I have noted elsewhere in this blog.
4...Bc5 5.Bxf7+
When Black captures the Bishop, the game will transpose into a "modern" Jerome Gambit variation, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6.
The Database contains 1072 games with this position, with White scoring 41%.
5...Kxf7 6.Nxe5+ Nxe5 7.d4
ndrwgn has a good bit of experience with this move. The Database shows he has a record of 23-22-1.
7...Nxe4
Black realizes he will lose a piece, and decides not to worry
about it - he will grab a pawn, instead. A slightly stronger move move here, 7...d5, is based on similar reasoning - let White choose what piece he wants, while Black plans to grab a pawn with a subsequent ...dxe4.

Probably best was 8...d5.
9.Qd5+ Ke7
White will collect the Knight at e4, with advantage. (That was quick.)
10.Qxe4 Re8 11.f4 d5
Very often Black's last move is part of a good counter-attack for Black in the Jerome Gambit (see the note to move 8 for example) but in this case - a blitz game - the defender has overlooked something.
12.cxd6+
The capture with check makes all the difference in the world.
12...cxd6 13.fxe5 Qxe5 14.Bg5+ Kd7 15.Rf7+ Re7
A visual (the Rook is actually attacked 3 times and only defended 2) or clock error. After 15...Ke6 16.Qxe5+ dxe5 17. Rxg7 Black would still be lost.
16.Rxe7+ Qxe7 17.Qxe7+ Kc6 18.Nc3 Black resigned
