The other day I ran into some games in The Database where a computer - GriffySr at FICS - was playing White.
What???
I suddenly had visions of Steffen Jakob's Crafty clone Brause and his own creation Hossa - both set up to play the Halloween Gambit (1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Nxe5!?).
How cool would it be to have an engine playing the Jerome Gambit!?
It turns out, GriffySr is not that engine, but it was fun to look at its games, anyway!
GriffySr - asmsk
standard, FICS, 2002
1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5
Okay, if you play the Jerome Gambit, someday you will face this move. The "objectively" best response is 4.Nxe5, but that shouldn't be your first choice - and it is not GriffySr's choice, either.
4.Bxf7+ Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 hxg6 8.Qxg6+ Ke7 9.d4 Bh6 10.Bxh6 Rxh6 11.Qg5+ Nf6 12.Qg7+ Ke8 13.Qxh6 c6 14.Nd2 d5 15.e5 Ne4 16.Nxe4 dxe4 17.Qg6+ Kf8 18.e6 Qxd4 19.Qf7 checkmate
Here's another line.
GriffySr - ccie
standard, FICS, 2008
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
Again, if you are looking for a Giuoco Piano to transform into a Jerome Gambit, the Semi-Italian defense is designed to side-step that. White can temporize with 4.0-0 or 4.Nc3 and hope Black will then play 4...Bc5 - or he can advance in the center.
4.d4
After 4.Nc3 Black added a second bad idea, and was crushed: 4...Na5 5.Bxf7+ Kxf7 6.Nxe5+ Ke8 7.Qh5+ g6 8.Qxg6+ Ke7 9.Nd5 checkmate, GriffySr -mackadee, FICS, 2002.

The alternatives are poor, but sometimes played:
