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!

9.d3
White agrees to the exchange of Queens.
Again, a recent game where that did not happen immediately: 9.Qg3 Nf6 10.d3 d5 11.Nc3 dxe4 12.dxe4 Ng4 13.O-O Bxf2+ 14.Rxf2 Qxf2+ 15.Qxf2+ Nxf2 16.Kxf2 c6 17.Be3 Be6 18.Bd4 Kf7 19.Ke3 Rhd8 20.Ne2 b6 21.Bc3 Rd7 22.Nd4 c5 23.Rf1+ Ke7 24.Nc6+ Ke8 25.Ne5 Rc7 26.a3 Rd8 27.h3 Bc8 28.Rf3 Bb7 29.Nd3 Re7 30.Nf2 Rd6 31.Rg3 Rde6 32.Rg4 g6 33.h4 h5 34.Rf4 Kd7 35.g3 Kd8 36.Bf6 Kd7 37.Bxe7 Kxe7 38.Nd3 a5 39.c3 a4 40.Nf2 Ba6 41.g4 Rd6 42.gxh5 gxh5 43.Rf5 Rg6 44.Rg5 Rxg5 45.hxg5 Bf1 46.Kf4 Ke6 47.Nd1 h4 48.Ne3 Be2 49.Ng4 h3 50.Nh2 Kf7 51.Kg3 Kg6 52.Nf3 Bxf3 53.Kxf3 Kxg5 54.Kg3 h2 55.Kxh2 Kf4 56.e5 Kxe5 57.Kg2 Kd5 58.Kf2 Kc4 59.Ke2 Kb3 60.Kd3 Kxb2 61.c4 Kxa3 62.Kc3 Ka2 63.Kc2 Ka3 64.Kc3 Ka2 65.Kc2 a3 66.Kd3 Ka1 67.Kc3 a2 68.Kd2 Kb1 69.Kd3 Black resigned, KNVB - PsychoPato, 3 0 blitz, Chess.com 2020.

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
