the Jerome variation, first played in a couple of correspondence games between Daniel Jaeger and Alonzo Wheeler Jerome in 1880.
The games in the notes to the main game, below, are worth playing over, too, to get a better understanding of White's and Black's play.
It must be pointed out that the Jerome Gambit player's ever-present ally - the chess clock - also had a hand in some of the games presented, as well. Most show White winning while having only 1 or 2 seconds of thinking time per move!

The game looks balanced. Komodo 10 thinks White should noodle around with 23.Bh4 and 24.Bg3, but this is a 5-minute game, and the first player opens things up - not necessarily to his advantage.
23.f6 gxf6 24.Rxf6 Ng6 25.e5 dxe5 26.Nxe5 Bxe5 27.dxe5 Rf8 28.Rd6 Bf5 29.Rd2 Rad8
For the moment, at least, Black's pieces look more impresive than White's extra pawns.
30.Rde2 Be6 31.Bf2 Rf5 32.Bd4 Nf4 33.Re4 Bd5 34.Bb6 Re8 35.R4e3 Nxg2 36.Rg3+ Kf7 37.Rxg2 Bxg2 38.Kxg2 Rexe5 39.Rxe5 Rxe5
Black has consolidated his advantage, up the exchange.
40.Kf3 Ke6 41.Bc7 Rh5 42.Ke4 Kd7 43.Bg3 b5 44.axb5 cxb5 45.Kd4 Kc6 46.c4 b4 47.Kd3 a4 48.Kc2 Kc5 49.b3 a3 50.Bf4 Rh3 51.Bg3 h5 52.Kb1
Things look dire for White, but, what have I been saying the last couple of weeks?
Black can sometimes "solve" the Jerome Gambit, if he is given enough time. The thing is, in bullet and blitz chess, he often does not have enough time.
And, so here, not surprisingly... Black lost on time
