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.



















Vazquez suggested that instead of 10.c3 White should have played 10.Qd8, and after 10...Bb6 11.e5 dxe5 12.Qd3
White would have had the better game. (This is the earliest incidence of this analysis that I have seen; Munoz and Munoz, in reporting the Anonymous - Blackburne game in the August 1885 Brooklyn Chess Chronicle, had simply suggested 10.Qd8)
