Still, it was fun to see Philidor1792 in the following game take on the one defense that I worry about the most, played by a computer this time, at that, and wrestle it to the ground for a split point.
A computer can not make sense of the Jerome Gambit? Now, that's a surprise!

The storm clouds gather.

11.e5+
A couple of alternatives from The Database:
11.Qxc5+ Kxc5 12.gxh4 d5 13.e5 Bg4 14.d4+ Nxd4+ 15.Kd2 Nf3+ 16.Ke3 d4+ 17.Kf2 Nxh4 18.Nd2 Raf8 19.Kg3 h5 20.Kxh4 Nf5+ 21.Kg5 Rh6 22.h3 Be2 23.Ne4+ Kd5 24.Nf2 Re8 25.Re1 Ree6 26.c4+ Bxc4 White forfeited on time, fehim - vshamis, FICS, 2008;

11...Kc6
Instead, 11...Kd5 12.Qd3+ 1-0 was the imaginary "R.F."-"Nibs" telephone chess game of 1899.
12.Qe4+ d5 13.exd6+
Or 13.Qxf3 Bg4 14.gxh4 Bxf3+ 15.Ke1 Bxh1 16.c3 Bg1 17.d4 Bxh2 18.Kf2 Rhf8 19.Na3 Be4 20.b4 Ng6 21.c4 Nxf4 22.cxd5+ Nxd5+ 23.Ke2 Nxb4 24.Ke3 Bd5 25.Bd2 Nxa2 26.Nc2 Rf4 27.Kd3 Rxh4 28.Rxa2 Rh3+ 29.Ke2 Bxa2 30.Nb4+ Kb6 31.Nxa2 Bg1 32.Nc3 Bxd4 33.Nd5+ Kc6 34.Ne7+ Kd7 35.Nf5 Bxe5 White resigned, Siggus - mscp, FICS, 2007.
13...Nd5
The key. Otherwise: 13...Kxd6 14.gxh4 Bg4 15.Qa4 Ng1+ 16.Ke1 Bf3 17.d4 Bxh1 18.dxc5+ Ke6 19.Nc3 Rhd8 20.Be3 Nh3 21.Kf1 Nf5 22.Re1 Bc6 23.Qc4+ Kf6 24.Ne4+ Bxe4 25.Qxe4 Re8 26.Bd4+ Nxd4 27.Qxd4+ Kg6 28.Qd3+ Kf6 29.Qxh3 Rxe1+ 30.Kxe1 Re8+ 31.Kf2 Re4 32.Kf3 Rc4 33.c3 Rxc5 34.Qg4 Rb5 35.b4 Rf5 36.Qg1 c5 37.bxc5 a5 38.Qd4+ Kf7 39.Qd7+ Kf6 40.Qxb7 g6 41.c6 Rc5 42.c7 Rxc3+ 43.Ke2 Kf5 44.c8Q+ Rxc8 45.Qxc8+ Kxf4 46.Qe6 a4 47.a3 h5 48.h3 Kg3 49.Ke3 Kxh4 50.Qf6+ g5 51.Kf3 Kxh3 52.Qxg5 h4 53.Qg2 checkmate, ionman - mscp, FICS, 2005.
Hmmmm.... That's the second game where ionman faced this defense 7 years ago. I need to catch up with him...
14.gxh4 Bg4 15.Qa4+ b5 16.Qa6+ Nb6 17.h3
Varying from 17.c4 Nd4+ 18.Ke1 Rhe8+ 19.Kf2 Nf5+ 20.Kf1 Bh3 checkmate, abhailey - peonconorejas, net-chess.com, 2008, the first "real" game where I saw this particular defense. I was convinced four years ago that the Queen sacrifice was discovered with the help of a computer (The Database, with earlier games, was not available until January 1, 2010.)
17...Bh5 18.c3 Nd4+ 19.Ke1 Nc2+ 20.Kf1 Rhe8 21.d4 Bxd6 22.d5+ Kd7 23.Qxb5+ Kd8 24.Rg1 g6
In this chaotic position, Black is better.
