Jerome Gambit: Over Quickly

One attraction of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is that it can produce an attack that brings the game to a close, quickly. 

The following blitz game is a good example.

Littleplayerparis - r-ex

3 2 blitz, lichess.org, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Ke8 

Black declines the second sacrifice. There are 427 games with this move in The Database. White scores 50%.

6.Qh5+ 

White takes advantage of the fact that Black's King has moved back to e8 - an aggresive check pushes forward his attack.

The computers recommend 6.Nxc6, which would be met by 6...Qh4!?, a counter-attack that remains unplayed.

6...g6 7.Nxg6 hxg6 

The alternative, 7...Bxf2+ acknowledges that the Bishop will be lost, and Black gets a pawn for it, following up with 8.Kxf2 Nf6. 

Littleplayerparis has also faced 7...Nf6 directly, 8.Qxc5 hxg6 9.d3 (9.Qg5 Nxe4 10.Qxg6+ Black resigned, Littleplayerparis - Kazeeeem, 3 2 blitz, lichess.org, 2021) 9...Qe7 10.Qe3 d5 11.exd5 Qxe3+ 12.Bxe3 Nxd5 13.Nd2 Nxe3 14.fxe3 Nb4 15.Kd1 b6 16.a3 Nd5 17.Ke2 Bb7 18.e4 Nf4+ 19.Kf3 g5 20.g3 Ne6 21.b4 Nd4+ 22.Ke3 Nxc2+ White resigned, Littleplayerparis - Level172, 5 0 blitz, lichess.org, 2020 

8.Qxh8 Nce7 

Or

8...Qf6 9.Qxg8+ Qf8 10.Qxg6+ Qf7 11.Qxf7+ Kxf7 12.O-O Nd4 13.Na3 d6 14.c3 Bxa3 15.bxa3 Nc2 16.Rb1 Bg4 17.f3 Nxa3 18.Bxa3 Black resigned, Littleplayerparis - FurkanAkyuz0, 5 0 blitz, lichess.org, 2020; or 

8...Kf8 9.d3 d6 10.Bh6+ Kf7 11.Qg7+ Ke6 12.Qxg6+ Nf6 13.Bg5 Bd4 14.c3 Black resigned, Littleplayerparis - nizzy47, 5 0 blitz, lichess.org, 2020; or

8...Qh4 9.Qxh4 Nd4 10.Kd1 d6 11.c3 Nb5 12.a4 g5 13.Qh5+ Kd7 14.Qf7+ Kc6 15.axb5+ Kxb5 16.d4 Bb6 17.Qxg8 Bg4+ 18.f3 Bh5 19.Qxg5+ Kc4 20.Qxh5 Re8 21.Qd5+ Kd3 22.Re1 c6 23.Re3 checkmate, Littleplayerparis - RSeverino, 5 0 blitz, lichess.org, 2021; or 

8...Kf7 9.Qh7+ Kf8 10.c3 Nf6 11.Qxg6 Nxe4 12.Qxe4 Ne7 Black resigned, Littleplayerparis - Kharteegayanz_7, 3 2 blitz, lichess.org, 2021

However, at this point Black resigned.

This might have been because Black realized there would be a second pin on his Knights, and there was nothing but pain ahead, after 9.d4 Bb6 10.Bg5.
