Jerome Gambit: Loyal Opposition

Even after 78 games where I faced the Jerome Gambit myself (instead of playing it), scoring 86% in the process, it still feels a bit odd to find myself playing as Black.

Knowing the attack helps me prepare the defense.

Matheus - perrypawnpusher

Wal2010's 3rd Thematic, Chess.com, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d3 

A "modern" Jerome Gambit, versus 5.Nxe5+, the "classical" variation chosen by Alonzo Wheeler Jerome.

5...Nf6 6.Ng5+ 

I have faced alternatives

6.O-O as in drewbear - perrypawnpusher, Jerome Gambit 3 thematic, chessworld.net, 2008 (0-1, 22); 

6.Nxe5+ as in mika76 - perrypawnpusher, GameKnot.com, 2008 (1-0, 32); 

6.c3 as in Gary_Seven - perrypawnpusher, Jerome Gambit 3 thematic, ChessWorld.net,  2008 (0-1, 30); 

6.Bg5 as in slp011- perrypawnpusher, Chess.com, 2024 (0-1, 8); and

6.Nc3 as in LithuaniaS - perrypawnpusher,  Jerome Gambit Classic #1, Chess.com, 2024 (0-1, 6) 

6...Kg8 

Or 6...Ke8 as in madmadmal - perrypawnpusher, blitz,FICS, 2009 (0-1, 53) 

7.f3 

Again, I have faced other lines

7.c3 as in RattyMouse - perrypawnpusher, blitz,FICS, 2009 (1-0, 31); 

7.Nc3 d6 8.Nd5 h6 9.Nxf6+ Qxf6 10.h4 Qxf2 checkmate, as in eliadr - perrypawnpusher, Chess.com, 2024; and

7.Be3 as in bushytail - perrypawnpusher, blitz,FICS, 2008 (1/2-1/2, 50) and ce_1 - perrypawnpusher, Chess.com, 2024 (0-1, 25). 

7...d6 

After the game, Stockfish 17.1 assessed Black's position as being better by about 4 3/4 pawns.

Does that shake my faith in the Jerome?

Nah.

8.Nc3 h6 9.h4 

Wow. This guy is not holding anything back.

9...hxg5 10.Bxg5 Be6 

It is nice to have the two extra pieces for a pawn for a change.

11.Nd5 

An alternate idea is 11.Qd2 followed by 12.O-O-O.

11...Bxd5 12.exd5 Ne7 13.c4 c6 14.Qd2 cxd5 15.cxd5 

15...Qb6 16.Bxf6 gxf6 17.g4 

White's hopes are with a Kingside pawn storm, but he is missing something...

17...Bb4 18.Qxb4 Qxb4+ 19.Kf1 Qxb2  20.Re1 

20...Rc8 21.Re2 Rc2 22.Rhh2 Rxe2 

Missing the fun 22...Rxh4.

23.Rxe2 Qb1+ 24.Kf2 Qxd3 White resigned

7.c3 

Alternately, 7.a3 Bg4 8.b4 Bd4 9.c3 Bb6 10.Nxb6 axb6 11.Bxf7+? (not the time to go Jerome-ish, this move is based on miscalculation) 11...Kxf7 12.Nxe5+ Nxe5 13.f3 Be6 14.f4 Ng4 15.f5 Qh4 16.fxe6+ Kxe6 17.d4 Qxh2 checkmate, Alby - ZoranBogojevic, 3 0 blitz, FICS, 2024 

7...Be6 

A slip. 

An up-and-down alternative: 7...Bg4 8.b4 Bb6 9.a4 Nf6 10.a5 Nxd5 11.Bxd5 Nxb4 12.cxb4 Bd4 13.Rb1 c6 14.Bb3 0–0 15.d3 Qf6 16.Bb2 Bxb2 17.Rxb2 d5 18.exd5? (18.h3) e4 19.Rc2 Bxf3? (19...exf3) 20.Qxf3? (20.gxf3) exf3 21.g3 Qf5 22.Bc4 Qh3 White resigned, Leurette,M - Pintor,M, corr FICGS, 2020 

8.d4 exd4 9.cxd4 

9...Nxd4 

9...Na5 was better, but not much of an improvement: 10.Be2 Bb6 11.b4 Nc6 12.Nxb6 axb6 13.d5 forking two pieces.

10.Nxd4 Bxd4 11.Qxd4 

11...c5 

With a pawn for a piece, Black can try to hold on with 11...Nf6. However, the time control is 1 move in 3 days, so the clock is not going to save him

12.Qxg7 Bxd5 13.Qxh8

Sloppy. Instead, 13.exd5, since 13...Qf6 (to protect the Rook) is met by 14.Bb5+ Kd8 15.Bg5, pinning and winning the Queen.

13...Bxc4 14.Qxg8+ Kd7

15.Qxd8+ Rxd8 16.Rd1 d5 

Giving me a chance for a passer.Will it amount to anything? Do I need it to, up a Rook?

17.exd5 Kd6 18.Bf4+ Ke7 19.d6+ Kd7

The King re-establishes its blockade - temporarily.

20.Rac1 b5 21.b3 Be2 22.Re1 Re8 23.Rxc5

Eyeing c7.

23...Re4 24.Rc7+ Kd8 25.Bg5+ Ke8 26.d7+ Kf8 27.d8Q+ 

27...Kg7 28.Qf6+ Black resigned

The Mingrelia Defence Returns (Part 1)

                                                           

The Jerome Gambit is an odd enough opening that it can catch defenders unaware - the surprise value is not to be underestimated.

In the following game, however, my opponent "out-surprises" me; but if my intended Jerome Gambit is sketchy, his defense is also - although not as bad as the Jerome, at least in the computer's evaluation.

perrypawnpusher - MatheusDescia

"Wal2010's 3rd Thematic", Chess.com, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Qf6 

A rare defense - see "The Mingrelia Defence: The Jerome Gambit Contravened".

My opponent had every good reason to try this defense, as it erases much of my opening knowledge. Certainly, it avoids the Jerome Gambit!

It also adds some chess confusion. For example, here is a recent high level game with the same defense - I have used Geoff Chandler's "Blunder Table" to apply "?" where any move changed Stockfish 17.1's harsh position evaluations by more than a pawn. I think the time control was Game/60.

A side note:  the earlier post "A Bit More Chess History" introduces the related Greco Gambit, 1.e4 e5 2.Nf3 Qf6, and a couple of games from 1620. 

Also a game where the American champion, Paul Morphy, faced, and defeated, 2...Qf6. 

Finally, a modern blitz game between two players rated 2300+.

Now, back to the game at hand.

4.Nc3 

The earliest example that I have in The Database of 3...Qf6 is from a 10-game Joseph Henry Blackburne blindfold exhibition at the City of London Chess Club in 1871. 

Patrick T. Duffy, writing in The Westminster Papers, June 1871, commented

Black's opening may be associated with those appearing in the French works, under the denomination of Défenses faibles [weak defenses].

Quite possibly, the player of the Black pieces hoped to confound the blindfolded master in the game Diffy was referring to, although he was unsuccessful: 4.O-O d6 5.Nc3 Be6 6.Nd5 Bxd5 7.exd5 Na5 8.d3 h6 9.Bd2 Nxc4 10.dxc4 Qd8 11.Re1 Be7 12.Bc3 Nf6 13.h3 O-O 14.Nh2 Qd7 15.Ng4 Qf5 16.Nxf6+ Bxf6 17.Qd3 Qg6 18.Qxg6 fxg6 19.Re2 g5 20.b4 Rad8 21.a4 e4 White won, Blackburne,J - Manning,J, City of London CC, blindfold exhibition, 1871)

4...Bc5 5.O-O 

Or White can immediately choose to entice the enemy Queen to return home with 5.Nd5, e.g. 5...Qd8 (5...Qg6?! 6.Nxc7+ Kd8 7.Nxa8 Qxg2 8.Rf1 White won, Wall,B - NN, internet, 2020; 5...Qd6 6.Ng5 [6.c3 Nge7 7.d4 Bb6 8.dxe5 Qc5 9.Qe2 Nxd5 10.exd5 Na5 11.Bd3 d6 12.exd6+ Be6 13.dxe6 O-O-O 14.d7+ Kb8 15.e7 c6 16.e8=Q Qd5 17.Qxh8 Qxd7 18.Qxd8+ Bxd8 19.Bf4+ Kc8 20.b4 White won, Aguirre Inchaurbe,P - Segear,G, LSS, 2014] 6...Nh6 7.Qh5 Nd8 8.Nf3 c6 9.Nc3 Bxf2+? 10.Kxf2 Qc5+ 11.d4 Qxc4 12.Bxh6 gxh6 13.Qxe5+ Ne6 14.Qxh8+ Nf8 15.Qe5+ Ne6 16.Rhf1 d5 17.exd5 cxd5 18.Nxd5 Qxc2+ 19.Kg1 Kd8 20.Qd6+ Bd7 21.Ne5 Nf8 22.Qe7+ White won,  Abioye,Y - Gregoryanz,P, Winnipeg CAN, 2020) 6.c3 Bb6 7.a4 d6 8.b4 a6 9.Nxb6 cxb6 10.d4 Bg4 11.dxe5 dxe5 12.Bxf7+?

There is also the calm 5.d3, as in Sabirova,O - Danierova,R, Tashkent, 2011: 5...h6 6.Be3 d6 7.Nd5 Qd8 8.c3 Nf6 9.O-O Bg4 10.Bxc5 dxc5 11.Ne3 O-O 12.Nxg4 Nxg4 13.Bb5 Qd6 14.h3 Nf6 15.Bxc6 bxc6 16.Qe2 Nh5 17.g3 f5?! 18.exf5 Rxf5 19.Nh4 Rg5 20.Ng2 Rf8 21.Qe4 Nf6 22.Qc4+ Nd5 23.Rae1 Kh8 24.h4 Rgf5 25.Ne3 Rf3 26.Qe4 Nxe3 27.Rxe3 Rxe3 28.Qxe3 Rd8 29.Re1 Qxd3 30.Qxd3 Rxd3 31.Rxe5 Rd2 32.Rxc5 Rxb2 33.a4 Ra2 34.a5 Kg8 35.Kg2 Kf8 36.Rxc6 Rxa5 37.Rxc7 Ra3 38.Kf3 a5 39.Ke4 a4 40.Kf5 Ra2 41.f4 Re2 42.g4 Re8 43.Ra7 Rc8 44.Rxa4 Rxc3 45.Ra8+?

5...d6 

Instead, 5...Nh6 develops a piece, but does nothing about White's threatened Knight leap 6.Nd5 Bxf2+ 7.Rxf2 Qd6 8.d4 Ng4 9.Rf1 O-O 10.Nh4 Nxd4 11.Qxg4 Nxc2 12.Nf5 Qc5+ 13.Kh1 g6 14.Qg5 c6 15.Nh6+ Kg7 16.Qf6 checkmate, Wall,B - Guest442049, internet, 2017.

More to the point was for Black to put the Knight on e7, i.e. 5...Nge7 to be met by 6.d4 although there is also

Familiar

The following game is not a Jerome Gambit, but White's game turns on what would otherwise be called central "Jerome pawns".

The Bishop sacrifice on f7 is familiar, as well.

Jerome Gambit: Choosing the Right...

 

Never let it be said that I did not go to the corners of the Internet to find ways to help Readers gain an advantage in their chess games - or at least have enjoyment along the way.

Now, going beyond the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) let me direct you to -

"Choosing the Right Perfume for Chess and Concentration" by Raquel Ferrando

The main page - which also links to a blog, and academy - is International Master Alberto Chueca's, author of The Chueca-Vidyarthi Chess Opening. Play 1.Nc3!.

Readers may know 1.Nc3 as the Van Geet or Dunst opening, or have on their shelves Knight on the Left: 1.Nc3 by Harald Keilhack

Checking at 439 pages, IM Chueca's book is sure to add to the understanding of the opening. It also contains exercises to practice middlegames and endgames - well worth noting.

Round Two Begins

 

Round Two of "Wal2010's 3rd Thematic Tournament: Community Poll Winner Italian Game" has begun, and I am guaranteed to see at least one Jerome Gambit game - as an opponent has played the opening against me!

Best of luck, good chess, Matheus Descia!

I am also playing at least one Noa Gambit - I don't know why I keep doing that. (I'm 4 - 2 - 2 against it, but all of the games have been, well, ugly.)

Oh, and I'm also facing a Mingrelia Defence. You might have to look that one up.

Best of luck, good chess, perrypawnpusher!

Jerome Gambit Declined: Tidying Up

Looking over the recent post, "Jerome Gambit: Declined",  it seems a bit of a mess.

I am not sure how or why I got there. I know, I know, I can blame it on Stockfish, but still...

Let me say a few things - and then leave it alone.

The Database has 17 games that go 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kf8 5.b4. White scores 11 - 6 - 0.

It has 11 games from the Evans Gambit Accepted line of play: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.Bxf7+ Kf8. White scores 8 - 2 - 1

It has 7 games from the Evans Gambit Declined line of play: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bb6 5.Bxf7+ Kf8  White scores 2 - 5- 0

And that should be that.
