I really didn't know what to say about the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, so I turned it over to my computer. The analysis is by Rybka 3, inside the Fritz program; so the comments come from Fritz 8. I made the diagrams, though.
Warning: the machine is rather cold-hearted in its evaluations.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.0-0 Nf6
6.c3 Rf8 7.d4 exd4 8.Qb3+? 
Better was: 8.e5!? Nd5 9.b4 -/+
8...Ke8
8...d5 might be the shorter path: 9.Bg5 Bb6 10.Nbd2 -+
9.Re1
9.e5 Ng4 10.Bg5 Be7 11.Bxe7 Qxe7 -+ ( 11...Nxe7?! 12.Re1 -/+; 11...Kxe7?! 12.cxd4 Rf5 13.Qd5 =/+)
9...d6
9...Qe7 10.h3 -+ 10.cxd4
Better was: 10.Bg5 -+
10...Bb6??
Forfeits the advantage. Better was 10...Bxd4, the advantage is on the side of Black, 11.Bg5 h6 12.Nxd4 Nxd4 ( 12...hxg5?! 13.Nxc6 bxc6 14.e5 -+) 13.Qa4+ Nc6 -+ 11.e5 -/+ dxe5 12.dxe5??
Better was: 12.Nxe5 the rescuing straw 12...Ne7 13.Nc3 =/+ 12...Ng4 -+ 13.Bg5
13.Be3 Nxe3 14.fxe3 Bg4 -+
13...Qd7
13...Nd4 seems even better: 14.Bxd8 Nxb3 15.axb3 Bxf2+ 16.Kh1 Bxe1 17.Bxc7 Nf2+ 18.Kg1 Nh3+ 19.Kf1 -+ 14.e6

16...Bxf2+
16...Bd7!? 17.Ne4 Bxf2+ 18.Kf1 -+
17.Kh1 Rxf3??
Makes life more difficult. Better was 17...Bxe1 Black had this great chance 18.Nb5 Bg3 19.Nxd6+ Bxd6 -+ 18.Qg8+ Rf8 19.exf8Q+
19.Qxf8+ Kd7 20.e8Q#

I've also seen 8...Qe7 9.Qe3 Nf6 10.d3 d5 11.f3 dxe4 12.fxe4 Ng4 13.0-0+ Ke8 14.Qg3 Qc5+ 15.Kh1 Be6 16.Nc3 Kd7 17.h3 N4e5 18.d4 Qxd4 19.Rd1 Qxd1+ 20.Nxd1 Rad8 21.Bf4 Kc8 22.Bxe5 Nxe5 23.Qxe5 Bd7 24.Nc3 Rhe8 25.Qg3 g6 26.Nd5 Black resigned,

White, with some help (oh, those Knights!) has the better game, despite his lack of development.

One last slip.

Black's counter-attack is quite scary. White can hold on, and even drive back the enemy, according to Rybka 3, with 14.Bd2 Ng6 15.Rd1 Nf5 16.Be1 Qe2 17.hxg4, but that's a computer talking, not a human being.
