It is fascinating how many ways Black can defend against the Jerome Gambit. Here, he doesn't bother choosing which attacked piece to save and which to give up, he simply opens a line for more development, and lets White decide. The Database has 32 games with this position; White scores 55%.

Bill has also played the more sedate 9.Nc3 g6 10.Qf3+ Ke7 11.Bf4 g5 12.Bg3 Bd4 13.exd6+ cxd6 14.Rad1 Bc5 15.e5 d5 16.Nxd5+ Bxd5 17.Rxd5 Qb6 18.e6 Nf6 19.Rd7+ Nxd7 20.Qf7+ Kd8 21.Qxd7 checkmate, Wall,B -Guest3664337, PlayChess.com, 2018

An exchange of Queens would help Black.
12.exd6+ cxd6 13.Nc3 a6
It is not immediately clear what is wrong with this move, or, rather, how the alternative, 13...Rc8, would have been better. Upon examination, the Bishop at c5 will need more support, and the Rook will be less at risk at c8.

There was also 18...Qxa8.
18...Qc8
Black protects his Rook and hopes for an exchange of Queens. Alas, the position is more complicated than that. His best was the alternative, 18...Qf8, covering the pawn at g7 as well, but then 19.f4!? would threaten to open the f-file and allow White's Rook to attack the enemy King and Queen. If, then, 19...Kg6 20.fxe5 Rb8 21.Qxa6 Qc8 (the Black Queen is working hard on defense), White refocuses his attentions on the King with 22.Qd3+. The initiative, plus 4 pawns for the sacrificed piece, give the first player the clear advantage. In fact, Stockfish 10 points out that White now has a checkmate in 32 moves!
