I am pretty sure that a grandmaster, if ever confronted by the Jerome Gambit, would not bother with any of the fancier "refutations" such as Blackburne's Defense, but would simply return a piece with the so-called "annoying defense" (see, for example 1, 2, 3) and then grind down the attacker from there.
It is not easy to beat Bill Wall in the Jerome Gambit, in the following game he is annoyed to death.
Wall,B - Guest3551214
playchess.com, 01.09.2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6
8.fxe5 dxe5 9.Qh3+ Ke7 10.Qg3 Kf7 11.Qxe5
White has two pawns for his piece, but he has a hard time whipping up an attack.
11...Qh4+ 12.g3 Qe7 13.Qh5+
Another indication of the difficult time that Bill is having is that this move is the first one out of "book". Black arrived at the board well-prepared.
13...g6 14.Qe2 Kg7 15.c3 15...Bb6 16.d4 c5
17.d5 Bh3 18.e5 Re8 19.Bf4 Bc7 20.e6 Bxf4 21.gxf4 Qh4+ 22.Qf2 Qh5 23.c4
23...Bxe6 24.dxe6 Rxe6+ 25.Kd2 Nf6 26.Kc1 Re2 27.Qf1 Rxh2 28.Rxh2 Qxh2
29.Nc3 h5 30.a4 h4 31.Ra3 h3 32.Rb3 Qg2 33.Qxg2 hxg2 34.Ne2 Re8 35.Ng1 Re1+ White resigned
The watchwords of Aaron Nimzowitsch (1886-1935) "restrain, blockade, destroy" come to mind in playing over the following game, as Black seems to utilize "hypermodern" concepts in has battle against a clearly "neo-romantic" chess opening.
It is one of the stranger Jerome Gambits I have ever seen.
Wall, Bill - Guest4149739
PlayChess.com, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Kf8
More common is 7...Ke8.
8.Qxc5+ d6
There is also 8...Qe7, as in Wall,B - Quack, Chess.com, 2010 (1-0, 22)
9.Qc3
The more-often played 9.Qe3 is as old as Vazquez,A -Carrington,W, Mexico, 2nd match, 1876 (1-0, 34) and as new as Wall,B - Vijay,V, Chess.com 2010 (1-0, 22) and Wall,B - LC, Chess.com, 2010 (1-0, 20)
9...Nf6 10.d3 Qe7
A slight improvement over 10...c6 as in Wall,B - Boris, Sparkchess.com, 2012 (1-0, 32). So far, we have a normal Jerome Gambit-style position.
11.O-O c6 12.f4 Bd7 13.f5 Ne5 14.h3
Bill later suggested 14.Bf4.
14...c5 15.g4 Bc6
White has activated his "Jerome pawns" and in response Black has started to restrain them and - with his Knights - blockade them.
An indication of how further "odd" the position can get is in Houdini's recommendation, instead of Black's last move: 15...g5 16.Bxg5 h5 17.h4 hxg4 18.a4 Be8 19.Nd2 Bf7.
16.g5 Nfd7 17.b4 h6 18.g6 Qh4
Black has about had it with all of White's pawn moves (Bill has also created this impatience in his opponents with repeated Queen moves) and decides to become aggressive, here threatening 19...Qg3+.
19.Kh2 b6 20.a4
Instead, 20.Bf4 was a possibility.
20...Nf6 21.Bf4
Bill shows how things could go horribly wrong for White: 21.bxc5? Nd5 22.exd5 Ng4+ 23.Kg2 Bxd5+ 24. Kg1 Qg3 checkmate
21...Re8
22.Nd2 Nh5 23.Bxe5 Rxe5
Threatening 24.. .Qg3+.
24.Rf3
White's King is still at risk: 24.bxc5? Qg3+ 25.Kh1 Rxe4 26.dxe4 (26.Nxe4 Bxe4+ 27.dxe4 Qxc3) 26...Qxc3.
24...Ke7 25.Rg1
White completes his development (!) and sets an interesting trap for his opponent.
25...Bxa4
This can lead to a slight advantage for White (better was 25...Kd7), or a whole lot more.
26.Ra1 b5
Black protects his Bishop and blocks the a-file against the White Rook. Instead, he should have retreated his piece with 26...Bd7 and let the White Rook in, facing a small disadvantage. However, this was far from obvious.
27.d4
With this move White takes over the game.
27...cxd4 28.Qc7+ Kf6
This leads to checkmate, whereas 28...Ke8 only leads to disaster after 29.Qc6+
29.Qxd6+
A bit faster was 29.Rg1
29...Kg5 30.Rg1+ Black resigned
It is ironic that Black, ahead in development for most of the game, should have his King expire with a Bishop offside and a Rook lollygagging at home.
The rhetorical question, "If a tree falls in the forest, and no one is there to hear it, does it make a sound?" came to mind the other day, as I was looking at the May 1874 issue of the Maryland Chess Review (Vol 1, No. 5).
Jerome Gambit aficionados know that the April 1874 issue of the Dubuque Chess Journal contained the article "A New Chess Opening" wherein Alonzo Wheeler Jerome presented his first analysis of his gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.
How did the chess world react to this momentous event?
As the Maryland Chess Review noted
The Dubuque Chess Journal for April is a considerable improvement on the March number. The cover contains a cut of friend Brownson and his wife, engaged in a game of chess. Its contents are, a photograph and biography of F. H. Curtiss, a number of his games and problems; victory and defeat, an article by Chas. Jacobus; regular games, regular problems, etc. Vol. VII commences with the May number, which would be a good time to subscribe.
I suppose that the Jerome Gambit material was included in the Review's "etc." reference. Sigh.
With one game left in the Italian Game Tournament at Chess.com (see "Swan Song") I relied on my trusty Jerome Gambit, and it did not fail me. Thus, I am likely to finish 3rd (out of 19 players) with a score of 13-6-5 (5-3-0 with the Jerome Gambit).
perrypawnpusher - MarkHundleby1
Italian Game Tournament, Chess.com, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
I was comfortable entering this line, as I have played it over 100 times, scoring 81%.
7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6
I have been here, too, in 44 games, also scoring 81%
10.O-O Qe7 11.Nc3 b6 12.f4 Bb7
13.f5 Ne5 14.d4 Ned7
A bit of an improvement over 14... Neg4, from perrypawnpusher - Navarrra, blitz, FICS, 2011 (1-0, 24) - which I still have to post here, one of these days.
15. Re1 Kd8 16. e5 dxe5 17. dxe5 Nd5
Bill Wall pointed out after the game that this was an error - one both my opponent and I overlooked. He suggested, instead, 17... Ng4!?
18.Qg3
Instead, 18.Nxd5 Bxd5 19.Rd1, followed by e6, as pointed out by Bill, would give White the advantage.
18...h6 19.Be3
Again: 19.Nxd5 Bxd5 20.Rd1
19...Nxe3 20.Rxe3 Qg5 21.Qxg5+
Bill preferred keeping the Queens on the board with 21.Qf2
21... hxg5 22.Rd1 Ke8
I remember analyzing this position, and then seeing my opponent's move, thinking I didn't think he could play that move... After 22...Kc8, instead, I agree with Bill that Black is a little bit cramped but still ok.
23.Nb5
I remember thinking that after having played 19.Be3 and 21.Qxg5+, that the text would look like another "just making moves" kind of piece-shifting. I could imagine my opponent thinking: Now we just exchange c-pawns with 23...Ke7 24.Nxc7 25.Rac8 Nb5 26.Rxc2 and then Black has deadly pressure on g2...
23...Ke7
Better 23...Rc8 24.Nxa7 Rd8 25.Nb5 Nc5 26.Nxc7+ Ke7 with an even game.
24.Nxc7 Rac8
25.f6+
The "Jerome pawns," instead, mix things up. They blow up the center, and suddenly Black's King is in great danger.
25...gxf6 26.exf6+ Kf8 27.Rxd7 Black resigned
Here we finish up burying the 3...h6 and 4...Na5 defense to the Jerome Gambit by taking a look at 4.Nc3 - instead of 4.0-0 ("Too Much of A Bad Thing") or 4.c3 ("Still A Mess").
freerunner - gGgeorgGg
blitz, FICS, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.Nc3 Na5
While the Semi-Italian Opening is playable for Black, and the Semi-Italian Jerome Gambit (4...Bc5 5.Bxf7+) has its risks, the introduction of ...Na5 pushes the whole defense over the cliff.
5.Bxf7+ Kxf7 6.Nxe5+ Ke8
6...Ke6 would get the same response.
7.Qh5+ Ke7
Or 7...g6 8.Qxg6+ Ke7 9.Nd5#, GriffySr - mackadee, standard, FICS, 2002.
8.Ng6+ Kd6
Let's face it, Black's King is already toast:
8...Kf7 9.Nxh8+ Ke6 (9...Ke7 10.Qxa5 Nf6 11.Qe5# shipwrecked - LScope, blitz, FICS 2011) 10.Qf7+ Kd6 11.Qd5+ Ke7 12.Qe5#; or
8...Ke8 9.Nxh8+ g6 10.Qxg6+ Ke7 11.Nd5#; or
8...Ke6 9.Qf5+ Kd6 10.Qd5#; or
8...Kf6 9.Qf5# moskvabr - amama, blitz, FICS, 2005.
9.Nxh8
This wins, as does 9.Qd5#, JakartaGuy - Kiloz, blitz, FICS, 2007 and (to use White's Knight) 9.Nb5+ Kc6 10.Nd4+ Kb6 11.Qb5#.
9...Nf6
Or 9...Qe7 10.Ng6 Qe6 11.Nxf8 Black resigned, xerthil - Tiur, blitz, FICS, 2005.
10.Qxa5
Picking up material while deleting a defender. Houdini gives a fun line using White's Queen Knight: 10.Nb5+ Kc6 11.Nd4+ Kd6 12.Nf7+ Ke7 13.Nf5+ Ke6 14.Nxd8+ Ke5 15.d4+ Kxe4 16.Qf3 checkmate
10...Qe7
11.e5+
Again, a line that shows the advantage of White's Knight being in play is 11.Nb5+ Ke6 12.Nd4+ Kd6 13.Nf5+ winning Black's Queen.
11...Qxe5+ 12.Qxe5+ Kxe5 13.Ng6+ Ke6 14.Nxf8+ Kf7 15.Nxd7 Bxd7
White has deftly exchanged a handful of pieces, leaving him simply a Rook and two pawns up. The rest of the game does not change this.
16.0-0 Re8 17.d3 g5 18.Be3 Bc6 19.Bxa7 h5 20.Bd4 Ng4 21.f3 Ne3 22.Bxe3 Rxe3 23.Rae1 Rxe1 24.Rxe1 b5 25.Ne4 Kg6 26.g3 Bd7 27.Nc5 Bc8 28.Re5 c6 29.b3 g4 30.f4 b4 31.Re4 Bf5 32.Rxb4 h4 33.Ne4 h3 34.Rb6 Bd7 35.Nc5
Fighting to the end, Black forfeited on time
Following up on the previous post ("Too Much of A Bad Thing"), here is another "public service announcement" about the difficulty of surviving 3...h6 and 4...Na5 when facing the Jerome Gambit - this time, the 4.c3 version.
Earlier warnings include "Still Worth Knowing", "Getting Creative," and "I'm Just Sayin'...".
hendrikgosse - codh
blitz, FICS, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.c3 Na5
Asking for the "Jerome treatment." White obliges.
5.Bxf7+ Kxf7 6.Nxe5+ Ke8
The comparatively better 6...Ke6 is well met by 7.Qh5 with a clear advantage to White.
7.Qh5+ Ke7
Or 7...g6 8.Qxg6+ Ke7 9.Qf7+ Kd6 10.Ng6 and Black will be down material, with an unsafe King.
8.Ng6+ Kf6 9.Nxh8 Nc6 10.Qh4+ Ke6 11.Qxd8 Black resigned
After 11...Nxd8 12.Ng6 White will be up the exchange and a couple of pawns.
As much as I enjoy watching (and playing) smashing attacks in the Jerome mode, I have to (again) warn defenders, out of a sense of fairness, that the following defense amounts to too much of a bad thing.
funnycrimes - MaxMBJ
blitz, FICS, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.O-O Na5
Black's move is provocative, especially when combined with 3...h6 ("like walking around with a Kick Me! sign pinned to the seat of your pants..." see "A Hot Rocket to Oblivion"). The "Jerome Treatment" is clearly recommended.
5.Bxf7+ Kxf7 6.Nxe5+ Ke8
Technically better is 6... Ke6, but Black's game would still be clearly worse.
7.Qh5+ g6
Looking this line up in The Database, only 3 of the 15 defenders (including this game) found this move; alas, all of them lost, anyhow.
On the other hand, 11 of the 12 players who chose an alternate 7th move lost as well (White blundered his Queen in the one Black win).
Here are the sordid details:
