Early last year I played a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) against Banassi (see "Platypus Perils and Follies"), and succeeded when my opponent lost his way in a complicated refutation line.
Although I won the game, I was so nervous at the time that I overlooked a checkmate-in-one along the way.
This time, I saw it.

blitz FICS, 20101.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
One of the many ways to defeat the Jerome Gambit, others being 6...g6, 6...Ng6 and 6...Kf8.
7.Qf5+ Kd6 8.f4 Qh4+
Wow!
The simpler 8...Qf6 was an effective defense, as was 8...Qd8, or 8...Qd7 or even 8...Kc6. The text holds the promise of a Queen sac, however.
9.g3 Nf3+ 10.Kd1
Now Black has 10...Ne7 11.e5+ Kc6 12.Qe4+ d5 13.exd6+ Nd5 14.gxh4 Bg4

Taking the Queen out of danger, but allowing...
