1.e4 e5 2.Bc4 Nc6 3.Nf3 h6
The Semi-Italian Opening. White has a number of moves - e.g. 4.0-0, 4.Nc3, 4.c3, 4.d3, 4.d4 - that can advance his game. Most allow Black to play 4...Bc5, opening up the opportunity to transpose to the Jerome Gambit with 5.Bxf7+.
Reminiscent of some ideas of Philidor1792. See "Essence of Evans / Jerome / Halloween", for example. It is interesting that Houdini 3, at 22 ply, gives only one response - 4...Bxb4 - that leads to an advantage for Black, and only by about 1/3 of a pawn.
Couriouser and curiouser. Black transposes to a Blackburne Shilling Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4), where his extra ...h7-h6 may or may not be more helpful than White's extra b2-b4.

The Jerome Gambit treatment.
5...Kxf7 6.Nxe5+ Ke6
7. Ng6 Bxb4
Instead, 7...Qg5 8.Nxf8+ (not 8.Nxh8, Qxg2 winning) Kf7 9.O-O Kxf8 would be about equal.
8.Qg4+ Kd6 9.e5+ Kd5 10.c4+
Even stronger is 10.c3 c5 11.cxd4, but White is thinking about Black's King.
A bit better was 10...Kc5, but Black's King would remain at risk.
11.Na3+ Bxa3 12.Bxa3 c5
This move is to protect the Knight, but it hems the King in.
