Black can be his own worst enemy when he does not take the Jerome Gambit seriously: one bad move (or idea) and White can do him in. The following game shows how to finish off one such "oops".

1.e4 Nc6 2.Nf3 e5 3.Bc4 Bc5 4.Nc3
White hesitates before committing to the Jerome Gambit...
4...Na5
...And is immediately rewarded.
5.Bxf7+
As with the line 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Nc3 Na5 in the Semi-Italian Opening, which we last saw in "Final Nail in the Coffin", Black dreams of exchanging off White's "Italian Bishop" with 5.Bb3?! Nxb3, but gets a rude, Jerome Gambit-ish shock.
Although the line is not frequently seen (only 15 games in The Database, White scores 77%), those who play the Jerome Gambit should remember how to deal with it.
Black's defense crumbles quickly.
5...Kxf7 6.Nxe5+ Ke8 7.Qh5+ g6 8.Nxg6 Nf6
A bit less painful was 8...hxg6 9.Qxh8.
9.Qe5+ Kf7 10.Nxh8+ Kg7 Black resigned
