My first win with the Jerome Gambit, in the second round of the "Italian Game Classic" tournament at Chess.com, was a bit of a journey through the opening's history.
An unfortunate slip by my opponent allowed me a tactical shot that brought the game to an early conclusion.
perrypawnpusher - PDX84
Italian Game Classic, Chess.com, 2019
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
Black courageously thinks of holding onto both sacrificed pieces. The compter chess analysis at Chess.com, after the game, identified the move as "best".
7.Qf5+
Alonzo Wheeler Jerome first suggested this move in the April 4, 1874 issue of the Dubuque Chess Journal. He also played 7.f4 and 7.O-O in correspondence games against S.A. Charles, and suggested 7.b4 "for analysis"; this was covered in the October, 1881 issue of Brentano's Chess Monthly.
A check of The Database shows 507 games with 7.Qf5+, with White scoring 48%, as opposed to 517 games with 7.f4, with White scoring 61%. There are no games with 7.b4.
7...Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3
Not 10.Qxe5+ this time. That move has given me mixed results, and a loss most recently: perrypawnpusher - djdave28, Italian Game Tournament, Chess.com, 2014, (1-0, 22); perrypawnpusher - djdave28, Italian Game Tournament, Chess.com 2015, (1-0, 32); and perrypawnpusher - Altotemmi, Giuoco Piano Tournament, Chess.com, 2016, (0-1, 51).
The Queen exchange is at least as old as Jerome, A - Jaeger, D, correspondence, 1878 (0-1, 68).
10...Nf6
This move makes a lot of sense.
Jerome faced 10...Ne7 in a correspondence game against Jaeger in 1878 (0-1, 68).
Lowe,E - Cudmore,D, correspondence, 1881, continued 10...b5 (½-½, 48).
Keeble,J - Cubitt,J, Norwich 1886, continued 10...c6 (1-0, 17).
11.d3 Ke7
Black dodges the crudest of threats - 12.Bf4, pinning his Queen to his King. The idea is at least as old as Vazquez - Giraudy, Mexico, 1876 (remove White's Queen Rook) 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.d4 Bxd4 9.c3 Bb6 10.f4 Qf6 11.fxe5+ Qxe5 12.Bf4 Qxf4 13.Qxf4+ Ke7 14.Rf1 Nh6 15.Qe5+ Kd8 16.Qxg7 Re8 17.Qg5+ Re7 18.Rf8 checkmate. Still, I've scored points from this "Optical Illusion" variation of the Jerome Gambit - see "Optical Illusion (1)", "Optical Illusion (2)" and "Disdainful Defender Defense".
Instead, 11...Kc6 was seen in Jerome, A - Colburn, correspondence 1879 (0-1, 34) and Jerome, A - Charles, S.A., correspondence, 1881 (unfinished).
12.Nc3 Bb4
Pinning the White Knight to keep it off of d5.
Instead:
12...g5 was seen in Jerome, A - Shinkman, W, Iowa, 1874 (0-1, 21);
12...d6 was seen in Jerome, A - Brownson, O, Iowa, 1875 (1-0, 43);
12...c6 was seen in Jerome, A - Amateur, off hand game, 1876 (1-0, 20); and
12...d5 was seen in Jerome, A - Pane, M, correspondence, 1878 (1-0, 41).
13.Bd2
I was amused to see that I had played 13.O-O here, years ago, in perrypawnpusher - PREMK, blitz, FICS, 2005. The idea was that 13...Bxc3 14.bxc3 Qxc3 15.Qg3!? would give White good play for the sacrificed pawn.
13...Rf8 14.O-O d6
Instead, in the post mortem, Komodo 10 recommended the brutal 14...Bd6, with the idea of forcing exchanges to eliminate White's attacking chances and highlight Black's piece-for-a-pawn advantage, e.g. 15.g3 c6 16.Bf4 Bc5+ 17.Kg2 Qh5 18.Na4 Qxf3+ 19.Rxf3 d6 20.Nxc5 dxc5 21.Raf1 Bg4 22.R3f2 Be6
15.Nd5+ Black resigned
White will recover his sacrificed piece. He will be a pawn up, with better development and King safety. Black decided not to play on.
