Alonzo Wheeler Jerome's Dream

If Alonzo Wheeler Jerome, the creator of the Jerome Gambit, ever dreamed of an exciting game, it might very well have looked like the following one.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Ng6

The kind of move - withdrawing a piece from attack - that someone unfamiliar with the Jerome Gambit might make quickly. (Best was 7...Qf6).

My guess is that at this point Bill got out his psychic micrometer, measured the apparent depth of his opponent's experience with (or understanding of) the opening, and chose a line of play that was most efficacious against an unschooled or uneasy opponent. 

8.f5+

Also seen:

8.Qf5+ as in Idealist - pvm, FICS, 2003 (1-0, 42), Petasluk - jackla, FICS, 2008 (1-0, 31), and Petasluk - popasile, FICS 2011 (0-1, 35);

8.Qxc5 as in Permanence - Pianisimo, FICS, 2008 (1-0, 17) and Permanence - jgknight, FICS, 2008 (0-1,38); and

8.Qd5+ as in Siggus - svetma, FICS, 2007 (1-0, 36).

All of these games can be found in The Database.

8...Kd6

Or 8...Ke5, which led to a quick win for White in Superpippo - HarryPaul, FICS 2001 (1-0, 15).

9.fxg6 Kc6

Instead, Black had to fight back with 9...Nf6.

10.Qd5+ Kb6 11.Qb3+ Kc6

Surprisingly enough, Black's King can escape with 11...Ka6 - if he keeps his wits about him. Sure, White can then win back a piece with 12.Qc4+ b5 13.Qxc5, but after the counter-attack 13...Qh4+!? Black can get his Queen over to protect His Majesty, e.g. 14.Kf1 Qxe4 (Black could also try 14...Ne7 with the idea of 15...Rf8+)15.d3 Qc6 when 16.Qxc6 dxc6 17.gxh7 gives White a small advantage, according to Houdini 3.

12.Nc3 hxg6 

Now White finishes things off.

13.Qd5+ Kb6 14.Na4+ Ka5 15.b4+ Kxa4 16.Qb3+ Kb5 17.a4+ Kc6 18.Qd5+ Kb6 19.Qxc5+ Ka6 20.Qa5 checkmate
