1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Ng6
I noticed that The Database has games of Jerome Gambit regulars HauntedKnight, jfhumphrey, ndrwgn, stretto and yorgos facing this move, so it is worth being prepared for it.
7.dxc5 Nf6
Or 7...d6 8.Qd5+ Be6 9.Qxb7 N8e7 10.f4 Bc4 11.Nd2 Rb8 12.Qxa7 Bb5 13.cxd6 cxd6 14.a4 Bd7 15.O-O Qb6+ 16.Qxb6 Rxb6 17.Nc4 Rc6 18.b3 Be6 19.f5 Bxc4 20.fxg6+ Kxg6 21.bxc4 Rxc4 22.Ra3 Rxe4 23.Rg3+ Kh5 24.Rg5+ Kh4 25.g3+ Kh3 26.Rh5+ Kg4 27.Rh4 checkmate, Wall,B - TenAndOnly10, lichess.org, 2016.
8.Be3
Bill has also played 8.Nc3, e.g. 8...Re8 (8...Qe7 9.Qd4 Re8 10.O-O Kg8 11.Bg5 Qe5 12.Qc4+ d5 13.cxd6+ Be6 14.Bxf6 gxf6 15.Qb4 cxd6 16.Rad1 Red8 17.Nd5 Bxd5 18.Rxd5 Qxe4 19.Qxe4 Black resigned, Wall,B - Silveira,J, lichess.org, 2016) 9.O-O Kg8 10.Re1 d6 11.cxd6 Qxd6 12.Qf3 Bg4 13.Qe3 Nd7 14.h3 Be6 15.Rd1 Qe7 16.f4 Bf7 17.b3 Nf6 18.e5 c6 19.Qf2 Nd5 20.Nxd5 Bxd5 21.c4 Bf7 22.Bb2 Nf8 23.f5 Rad8 24.Qxa7 Rxd1+ 25.Rxd1 Rd8 26.Rxd8 Qxd8 27.Bd4 g6 28.e6 Bxe6 29.fxe6 Nxe6 30.Be5 Qc8 31.Qb8 Qxb8 32.Bxb8 Kf7 33.Kf2 Ng5 34.Bf4 Ne4+ 35.Ke3 Nc3 36.a4 Ke6 37.Bh6 Nd1+ 38.Ke2 Nc3+ 39.Kd3 Nd1 40.Bd2 h5 41.Ke2 Nb2 42.Bc1 Nxa4 43.bxa4 Kd6 44.a5 Kc5 45.Kd3 b5 46.Ba3+ b4 47.Bxb4+ Kxb4 48.a6 Black resigned, Wall,B - Guest688630, PlayChess.com, 2017.
8...Re8 9.Nc3
Black has done well. He has a piece for two pawns, and his King is almost safe. But, now he becomes careless, instead of asking himself: Is that pawn on e4 actually available? (Perhaps we are dealing with a negative "halo effect" as well.)
9...Nxe4 10.Nxe4 Rxe4
11.Qf3+
I guess not. Now Black's game falls apart.
11...Qf6 12.Qxe4 d5 13.Qxd5+ Be6 14.Qxb7 Black resigned
White is ahead an exchange and three pawns.
