Jerome Gambit: Ooops



In the following game, the players march down the main line of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) until White allows the exchange of his Rook for a Bishop - permitting Black to deliver a draw by repetion.

Ooops.

Blitz. It happens.

Jerome Gambit, Still Faster



Okay, set up your chessboard (2D or 3D) and play through the following bullet game.

It might help if you realize that the players used, on average, less than a second per move.

Race through it, to get a sense of the play, as it happened.

It will probably take more than a minute to do that.

Abrahams Jerome Gambit: One Benefit



The player of the Whites pieces in the following match has 600 games, in The Database, scoring a solid 60%.  

In particular, he has 223 games with the Abrahams Jerome Gambit, again scoring 60%.

IDLEH2017 - perozvicente

5 0 blitz, lichess.org, 2023

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ 

The Abrahams Jerome Gambit.

3...Kxf7 4.Qh5+ Kf6 

4...Kf6 was also seen in IDLEH2017 - Arhip700, lichess.org, 2021 (1-0, 5) 

One benefit for White in this opening, versus the Jerome Gambit proper (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), is that Black really has only one good response to the Queen check - and this isn't it.

5.Nf3 

This move allows the game to transpose to a position like the Jerome Gambit mentioned above, as if the Queen had ghosted through the Knight on f3.

Sharper was 5.Qf5+ Ke7 6.Qxe5+ followed by collecting the Bishop on c5, as in and IDLEH2017 - madel4665, lichess.org, 2024: 5.Qf5+ Ke7 6.Qxe5+ Kf7 7.Qxc5 Nf6 8.e5?!

5...Nc6 6.d4 

White avoids 6.Nxe5 Bxf2+ 7.Kxf2 Nxe5 which would still be good for him after 8.Qf5+ Ke7 9.Qxe5.

6...Qe8 

To exchange Queens, but overlooking White's threat.

7.Bg5+ Ke6 Black resigned

Jerome Gambit: A Funny Draw



The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can grant White some exciting wins - despite being a "refuted" opening.

Because of its chaotic nature, however, the Jerome can lead to a loss - or some pretty funny draws

We have already seen a chuckle in ZeKnightRider - GrandLoser101, blitz, lichess.org, 2024 (1/2-1/2, 73). See 'Jerome Gambit: Good News, Bad News".

The following game probably put a smile on White's face.


feritTurkey - Qauknochen

5 0 blitz, lichess.org, 2025

1.e4 e5 2.Bc4 Nc6 3.Nf3 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe7 


Black plays Whistler's defense, and dares White to take the Rook.

8.Qxh8 

Safer was 8.Qf4+ or 8.Qd5+

8...Qxe4+ 9.Kd1 Qxg2 


There are 54 games with this position in The Database, with White scoring a surprising 43%.

Stockfish 16.1 (32 ply) evaluates Black as being 4 3/4 pawns better.

10.Qxh7+ 

White has to distract Black from his aggressive ideas.

10...Kf8 

Or 10...Kf6 11.Qh4+ g5 12.Qh7 Qxh1+ 13.Ke2 d6 14.Qh8+ Kf7 15.Qh5+ Ke6 16.Qg6+ Nf6 17.d4 Qe4+ 18.Be3 Qxg6 19.dxc5 dxc5 White resigned, feritTurkey - AgustinBarba, lichess.org, 2023.

11.Re1 

The fact that the computer suggests that White's best move was 11.d4, giving up a Rook, shows the danger of the line.

feritTurkey has tried that before: 11.d4 Qxh1+ 12.Ke2 Qe4+ 13.Be3 Bxd4 14.Nd2 Bxe3 15.fxe3 Qxc2 16.Rf1+ Qf5 17.Rxf5+ gxf5 18.Qxf5+ Ke7 19.Qg5+ Nf6 20.Qg7+ Ke6 21.Nf3 b6 22.Nd4+ Ke5 23.Qg5+ Ke4 24.Qxf6 Ba6+ 25.Kf2 Rh8 26.Qf5 checkmate, feritTurkey - Animalium, lichess.org, 2023.

11...Qg4+ 


This is a 5-minute game, so it is possible that the clock figured into this move.

Black needed one more piece in play, therefore: 11...d5 12.c4 Luft Qf3+ 13.Re2 Qh1+ 14.Kc2 Bf5+ 15.d3 dxc4 16.Bh6+ Nxh6 17.Qxh6+ Kg8. White's Knight is pinned to the Rook, and this leaves the first player undermanned.

feritTurkey has also faced: 11...Qf3+ 12.Re2 Qg4 13.d3 Qg1+ 14.Re1 Qxf2 15.Bh6+ Nxh6 16.Qxh6+ Kf7 17.Qh7+ Kf6 18.Qh8+ Kf7 19.Qe8+ Kg7 20.Qe5+ Kh6 21.Qh8+ Kg5 22.Qe5+ Qf5 23.Qg3+ Qg4+ 24.Qxg4+ Kxg4 25.Nc3 c6 26.Re4+ Kf5 27.Kd2 d5 28.Rf1+ Kg5 29.Re5+ Kh6 30.Ne2 Bh3 31.Rf3 Bg4 32.Rf7 Rf8 33.Rxf8 Bxf8 34.Nd4 Bg7 35.Re7 Bxd4 36.Rxb7 Bc8 37.Rxa7 Bxa7 White resiged, feritTurkey - DrPapiChessPapi, lichess.org, 2025

12.Re2 Qg1+ 13.Re1 Qg4+ 14.Re2 Qg1+ 15.Re1 Qg4+ Draw


Danger? Ha! I laugh at danger...

Abrahams Jerome Gambit: Exploring

 



I have joined the new BISHOP'S OPENING CUP 2025 at Chess.com - 250 players, time control 10 days per move (!).

My hope is to play a number of Abrahams Jerome Gambits, 1.e4 e5 2.Bc4 Bc5 3.Bxf7+, a line that I have not tried before, but is worth exploring.

The Database shows 18,980 games with the line. White scores 51%.

We shall see.

Jerome Gambit: Caffeine Deficiency Disorder



The other day, very early in the morning, suffering from Caffeine Deficiency Disorder, I played an odd Jerome Gambit against an online bot.

We reached the following position. Having regained my sacrificed material, I imagined that I was Alonzo Wheeler Jerome.


16.Bf4 Qd4+ 17.Kh1 Kb7 18.Nc3 c5 


This can't be good for Black.

19.e5+ d5 20.exd6+ Kb6 21.Nd5+ Kb7 

22.Nc7+ 

Fair enough, although 22.Nf6+ Kb8 23.Qc6 would have been a bit faster.

22...Kb6 23.bxc5+ Qxc5 24.Be3 Rhd8 25.Nxa8+ Ka5 26.Bxc5 g6 27.b4+ Ka4 28.Qd1 checkmate


Okay, that was fun. Still, in all fairness, it brings to mind a counter-balancing earlier post including

Pittsburgh Chronicle-Telegraph

February 27, 1884

In Cincinnati we met a number of players in the Mercantile Library, the chess room of which... We also had the pleasure of contesting several games with Mr. Jerome, of Paxton, Ill. He is well known as the author of the so-called Jerome Gambit, in which white sacrifices the Bishop by taking KBP on the fourth move of the Giuoco Piano game. Neither the gambit nor its author proved strong in the contest.

Jerome Gambit: Slow advance





Some Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games feel like White is racing to attack and win material or checkmate the enemy King. Here's what I have, the attacker says.

Other games move along at a leisurely pace, with White comfortable inquiring of his opponent, What do you have?

In the following game, Bill Wall takes the path between the two, slowly advancing, gaining ground until his pieces spring into action. Black is not prepared to defend, and, so, expires. 


Wall, Bill - Naren

There are almost 1,000 games with this position in The Database.
White scores 50%.
Bill has 136 games with this position in The Database. He scores 90%.
Stockfish 16.1 evaluates the position as about 2 1/2 pawns better for Black.
You pays your money and you takes your choice.

8.a4 

Practically a null move, asking Black What do you have?

According to The Database, the only Jerome Gambiteer to play this move is Bill.

8...Nf6 

Or 8...h6 9.O-O Nf6 10.Nc3 a6 11.f4 Nc6 12.Qd3 Rf8 13.Bd2 Kg8 14.Qc4+ Kh8 15.Rfe1 Bd7 16.Nd5 Nxd5 17.exd5 Ne7 18.Ba5 b6 19.Bd2 c5 20.dxc6 Bxc6 21.Rxe7 Qxe7 22.Qxc6 Rac8 23.Qxb6 Rxc2 24.Re1 Qf6 25.Qe3 Qxb2 26.Rd1 Rfc8 27.f5 d5 28.h3 a5 29.Kh1 d4 30.Qd3 R8c4 31.f6 gxf6 32.Qg6 d3 33.Qxh6+ Kg8 34.Qg6+ Kf8 35.Re1 Black resigned, Wall,B - Guest7904333, PlayChess.com, 2018

9.Ra3 

Allowing a possible Rook lift. 

He has also played 9.Nc3 c5 10.Qd2 Re8 11.O-O Be6 12.Rd1 d5  13.exd5 Bxd5 14.Nxd5 Nxd5 15.Qxd5+ Qxd5 16.Rxd5 Nc4 17.h3 Re1+ 18.Kh2 b6 19.b3 Ne5 20.Bb2 Re8 21.Rxe1 Black resigned, Wall,B - Guest3174027,PlayChess.com 2019

For the next 10 moves, the players arrange their pieces and skirmish, but Black remains with the advantage.

9...Rf8 10.Nc3 c5 11.Qd1 Kg8 12.O-O h6 13.Re1 Bg4 14.f3 Bh5 15.Nb5 d5 16.exd5 Nc4 17.Rc3 a6 18.Rxc4 axb5 19.Rxc5 bxa4


One positive thing in White's position is his passed d-pawn, and he uses it to spearhead a piece invasion.

20.d6 Be8 21.Rc7 b5 22.Ree7 


22...Nd7 

In club level play (and likely elsewhere) defending is often more difficult than attacking. Attack poorly, you may lose time or material; defend poorly, you may well lose the game.

Simplest was 22...Rf7, although 22...Bf7 would also do the job.

23.Bxh6 

This probably came as a shock.

23...Rf7 

If 23...gxh6, then 24.Qd5+ Bf7 25.Qf5 would threaten to win material, as well as close in on checkmate.

24.Qd5 Nf6 
25.Rxf7 

White's attack is so powerful, he can offer his Queen.

Black's best defense now still allows checkmate: 25...Qxc7 26.Rxf6+ Qf7 27.Rxf7 Bxf7 28.Qxa8+ Kh7 29.d7 Kxh6 30.d8Q Be6 31.Qh4+ Kg6 32.Qe8+ Kf5 33.Qeh5+ g5 34.Q4xg5#

23...Nxd5 26.Rxg7+ Kh8 27.Rh7+ Kg8 28.Rcg7+ Kf8 29.Rh8 checkmate



A fitting game for post #4,700 of this blog.

Jerome Gambit: He Should Have Stuck with Boring


The following short Jerome Gambit game illustrates the idea that a proper defense - and there are many - can (and, maybe, should) be boring and also correct. 

Stepping outside of "boring" can be very dangerous against Bill Wall.

Wall, Bill - Twister

SparkChess, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 7.c3 Nd3+ 


Black needs to surrender a piece, and this is how he does it. 

More "boring", but better for him, was 7...Be7 - the Bishop retreats after forcing a pawn, not a Knight, to c3.

8.Qxd3 Be7 9.Qf3+ 

Earlier, Bill had played 9.O-O Nf6 10.e5 in Wall,B - Anonymous, lichess.org 2020 (1-0, 23)

9... Ke8 10.O-O 

10...d5 

Or the less energetic 10...d6 as in Wall,B - Ripao, lichess.org 2017 (1-0, 18).

11.Nd2 dxe4 12.Nxe4 Nf6 13.Re1 


Black has the typical Jerome piece-for-two-pawns advantage, and if he could only castle now, he would be well off.

Since he can not castle, he looks to harass White's Queen - a mistaken idea that immediately gets tactically refuted.

13...Bg4 14.Nxf6+ gxf6 15.Qxg4 

15...Qd6 16.Bf4 Qc6 17.Qg7 Black resigned


White's Queen and Rook cause mayhem: there is a checkmate in 6.

Jerome Gambit: Just In Time

                                                          

Just in time, chessriddler contributes a game that fills in a gap in current Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) practice and theory.


chessriddler - mouathalsebaie

3 0 blitz, lichess.org, 2025

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

4...Kxf7 5.Nxe5+ Ke6  

This move was addressed recently in the post "You Can Pay Me Now or Pay Me Later" covering Wall, Bill - Docteur, SparkChess, 2025 (1-0, 11).

6.Qg4+ 

Sharp, but sacrificing another piece is best.

6...Kxe5 7.d4+ Nxd4


Not the correct capture. Better was 7...Bxd4, as seen in Wall, Bill - Docteur, SparkChess, 2025.

Chessriddler punishes the text move quickly.

8.Bf4+ Kf6 9.Bg5+ Kf7 10.Bxd8 Nxc2+


It is possible that Black counted on this fork to claw back some material.

11.Kd1 Nxa1 12.Qf5+ 

Simpler was 12.Qh5+ Kf8 13.Qxc5+ snagging the Bishop. But, remember, this is a 3-minute game, and a win is a win is a win.

12...Nf6 13.Bxf6 d6 14.Qg5 gxf6 15.Qh5+ Ke7 


Black has two Bishops for a Rook, but his cornered Knight could be at risk.

16.Nc3 Bxf2 

Tempting, but another factor in play is the risky position of Black's King, as White demonstrates.

17.Nd5+ Kd8 18.Qf7 


White has a forced checkmate in 15 - if Black's defense is the best.

18...Bd7 

Providing more resistance, but still leading to an eventual checkmate, is provided by 18...Bg4+.

19.Qxf6+ Ke8 20.Qe7 checkmate
