I am not particularly a fan of the Accelerated Semi-Italian Jerome Gambit, but for those who play it, the following game should be a reminder that a false move like 5...Ke8 for Black can lead to another kind of Instant Victory.
Ghandy - Kwanza
blitz, FICS, 2011
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+
White does not wait for a Black Bishop to appear at c5, he sacrifices anyhow. Although the opening does not appear to have a name, it looks like an Accelerated Semi-Italian Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke8
Perhaps thinking, on reflex, that the King will be safer here. However, we will now see an ending similar to that presented in "Instant Victory" and "Instant Victory Redux".
6.Qh5+ Ke7
Black can throw in 6...g6 as in GFcrafty - Suigeneris, blitz, FICS, 2001, but after 7.Qxg6+ the result will be the same.
7.Qf7+
Also successful was 7.Ng6+ Kd6 8.Qd5 checkmate as in Dasistes - GeorgeVonGeorge, blitz, FICS, 2008.
However, 7.0-0 was not successful, as in EvashUcrushU - mrcain, FICS, 2009, which continued 7...Nxe5 (7...Qe8 was a bit better) 8.Qh4+ (White should have taken the draw by repetition with 8.Qxe5+ Kf7 8.Qd5+ etc.) g5 9.Qg3 d6 White resigned.
7...Kd6 8.Nc4+
Not quite as accurate was 8.Qd5+ but it was sufficient for the full point after 8...Ke7 9.Ng6+ Ke8 10.Nxh8 Nce7 (falling on his sword) 11.Qf7 checkmate in Esistes - SURPRISE, blitz, FICS, 2010.
8...Kc5 9.Qd5+ Kb4 10.c3+ Ka4 11.b3 checkmate
Today's game is the same as GFcrafty - tomamelheim, blitz, FICS, 2001.
