Jerome Gambit: Ghosts of Moves Unplayed


Playing a 3-minute game often requires both players to put aside any thoughts of what moves they could have played, or should have mande, but didn't. With more time to reflect, such musings might help in forming future plans, but in blitz, they can haunt ongoing play.

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

Now, Black can choose Blackburne's Defense, 7...d6, or Whistler's Defense, 7...Qe7 - both are complicated and dangerous - or amongst a handful of lesser lines, e.g. 7...Bd6.

8...Kg7

The text move looks a little bit better than 8...Kf8, which might place the King in the way of a Rook that wants to be developed, e.g. eronald - ayushsankar1006, 5 0 blitz, lichess.org, 2020 (0-1, 23).

Not quite as strong as 9...Bb6levigun - obviously, 5d + 2d GameKnot.com, 2004, (0-1, 11) 

10.c3 Nf6 11.Qe5 

White has to be careful, with only one piece developed vs three, even with his strong pawn center. Fortunately, Black helps him out.

11...Qxe5 

Exchanging Queens in the Jerome Gambit if often a help to the defender. In this case - a 3-minute blitz game - Black has not looked deeply enough, however.

12.dxe5 Nxe4 13.cxb4 Re8 



14.Nc3 

A bit stronger was 14.0-0 Rxe5 15.Bf4 Re6 16.Bxc7. This possibility seems to haunt both player's thoughts during the next few moves, perhaps unconsciously.

14...Rxe5 15.O-O 

Of course, White can not now play 15.Bf4 Re6 16.Bxc7 because of 16...Nxc3+.

15...d5 16.Be3 

This is a solid move, although, again, 16.Bf4 was on.

16...c6

Black suddenly realizes that the 16.Bf4 skewer could win a pawn, so he moves that pawn to safety. But he overlooks something.

17.Bd4 

Black resigned

The Rook is a goner.

Jerome Gambit: Remain Vigilant


Cartoon victorian balloonist

Sometimes the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) explodes decisively. Other times, White has to bide his time, waiting for a tactical opportunity. In the meantime, Black has so also remain vigilant, as a slip could prove fatal.

Such a slip occurred in the following game.

Well, yes, White was threatening the Knight fork at g6...

If this were not a blitz game, White would probably have found 18.Nd7+ Ke8 19.Qa4!? Nf6 20.Nxf6+ Kf8 21.Nxh7+ Kg8 22.Bxh6+!? Kxh7 23.Be3 when he would have a Rook and 3 pawns for a Bishop and a Knight, which would be about equal in the middlegame (and maybe a slight bit better in an ending).

18...Ke8 

Black avoids the messy alternative, 18...Nxg6 19.fxg6+ Nf6 20.gxh7+ Bxh7 21.g5 hxg5 22.Qh5, but stumbles into checkmate from the other wing.

19.Qa4+ b5 20.Qxb5+ Black resigned



20...Qd7 21.Qxd7 checkmate is too painful to allow on the board.

Jerome Gambit: Active and Passive Sacrifices

The Jerome Gambit is based upon active sacrifices: 4.Bxf7+ and 5.Nxe5+. The attacker practically throws his pieces at the defender.

The following game also contains a passive Queen sacrifice: White places Her Majesty where she can be attacked, and then he just leaves her there. Black might as well capture, as the alternative is to let a pawn advance and promote to another Queen.

Black is thinking about castling-by-hand, always a prudent response to the Jerome Gambit.

12.f5 Ne5 13.Qb3+ 

Pausing to chase the enemy King away from safety.

13...Ke8 14.d4 N5c6 15.Qd3 Bd7 


A curious Jerome Gambit position! White, the gambiteer, has only 2 pieces developed to Black's 4. The material balance still favors the defender, who has a piece for 2 pawns. There is the matter of Black's King stuck in the middle of the board, however.

If White believes he has the advantage (and I believe he does), it's time for him to show it.

16.Bg5 h6 17.Bh4 g5 

This move is risky. It turns White's f-pawn into a protected passer. Worse, it allows White to open up the Kingside by capturing enpassant.

18.fxg6 Qc8 19.Rxf8+ Kxf8 20.Qf3+ Ke8 


The ugly alternative was 20...Bf5 21.Bxe7+ Nxe7 22.g4 Qe6 23.gxf5, when White's extra, avanced, pawns will prove decisive.

21.Qf7+ Kd8 22.d5 Be8 23.dxc6 

Funny. White can offer up his Queen. He can get another.

23...Bxf7 24.gxf7 Black resigned

Jerome Gambit: Hunter's Lament

cartoon biker bear

In Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games, it seems that victory for the attacker turns on a few things happening, while defeat turns on a few things not happening. In a 5-minute game, sometimes that works out, and sometimes it doesn't. But - the games are always exciting.

The Knight's attack on the Queen should serve no purpose. For example, if now 13.Qd3 Qh4 14.h3 and it will have to move.

13.Qg5 Qxg5 14.Bxg5 h6 15.Be3 Nxe3 16.fxe3 Ne7 



White has 2 pawns for his sacrificed piece, but they are not mobile. The exchange of Queens has taken the life out of his attack, as well. It will take some pluck and some luck to make progress.

17.Nd5 Nxd5 18.exd5 Bg4 19.e4 Rf8 20.e5 Rxf1+ 21.Rxf1 Ke7 22.e6 Rf8 

The protected, passed pawn is something of value, but for now it is effectively blockaded. If there were an attack on the tied-down King, White might be able to make something of the position. In the meantime, too many pawns are stuck on the same colored squares as the Bishop.

23.c4 Rxf1+ 24.Kxf1 Bf5 25.c5 Be4 26.c6 bxc6 27.dxc6 Bxc6 28.Ke2 Kxe6 29.Kd3 Bxg2 30.Kc4 c6

Jerome Gambit: Positional Cues


Sometimes, while playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), we can take a cue from our opponent as to which move to make or which plan to follow. See the following game.

SuperChinese - Zakir292
5 0 blitz, lichess.org, 2020

1. e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6



7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.O-O Be6


Cue #1: With a Knight on g6, this Bishop move should prompt a standard response from White.

11.f4 Bc4 12.d3 Qe7 

Black's idea reminds me of the Calvin and Hobbes book, Scientific Progress Goes "Boink" - Black follows the "scientific" idea of returning sacrificed material in order to break White's attack. However, he overlooks cue #2: his King and Queen will soon be on an opened file.

13.dxc4 Nxe4 

He could have tried 13...Kf7, to limit the damage.

14.Re1 Nc5

This might have been the move that Black had been counting on. In a 5-minute game, sometimes analysis does not go deep enough.

15.Qf2 Ne4 16.Qf3 

16...Ne5 17.Qxe4 Rf8 18.fxe5 Qf7 19.exd6+ 



White is a couple of pieces and a couple of pawns ahead. All he has to do is make sure he doesn't get checkmated, and he has the win.

19...Kd8 20.Qe7+ 

The simplest. Now 20...Qxe7 21.dxe7+ Kd7 22.exf8/Q+ Rxf8 would be quite enough. Instead, Black allows checkmate directly.

20...Kc8 21.d7+ Kb8 22.Qxf8+ Qxf8 23.Re8+ Black resigned 



Black takes his cue. The finish would be 23...Qxe8 24.dxe8 checkmate. Ouch!

Jerome Gambit: Amusement


From the pages of the Cincinnati Commercial Gazette, June 18, 1881
A letter received from Mr. A. W. Jerome calls attention to the fact that he does not claim the Jerome Gambit to be analytically sound, but only that over the board it is sound enough to afforda vast amount of amusement.
Sometimes, White is amused. Sometimes, Black is.

There is a lesson there, somewhere.


DeathStroke97 - lunareclipse777
15 10 blitz, Chess.com, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 



Black's move is strong - if he knows some of the refutations of the Jerome.

Black's move is weak - if he is merely trying to hold onto all of the sacrificed material.

7.Qf5+ Kd6 8.f4 Qh4+ 



Often Black plays 8...Qf6. Is the text move, instead, just an annoying check before the Queen moves to f6? Or - is there something more?

9.g3 Nf3+

Wow.

This move goes back to a fictional game presented in the American Chess Magazine, June, 1899, which lampooned the recent introduction of chess-by-telephone.

Such a move is also a strong indication the Black knows something about the Jerome Gambit, and has decided to launch a strong counter-attack. The line is complicated - The Database shows White winning 29 games, losing 21, and drawing 3 - but "objectively" dangerous for the first player.

10.Ke2 

White needed to play 10.Kf1, or at least 10.Kd1. It is not enough to rely upon his first impression that the Queens will be exchanged.

10...Nd4+

White resigned


After 11.Kd1 Nxf5 12.gxh4 Nxh4 it is true that the Queens have come off of the board - but Black remains 2 pieces ahead.

Jerome Gambit: A Good Idea


The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can affect defenders differently. Some will think "Somehow I never learned about this crushing attack, I am doomed" while others will think "I now have a won game that will play itself". Both mind sets can lead to disaster over-the-board, and another thought, that there are other games to play...

9...Ba6 10.d3 Nf6 11.Qb3 d5

Often a good move for Black, it is not well-timed here, as he has overlooked something.

12.Qa4+ Black resigned



Clearly, Black was discouraged after his slip. The game could have continued 12...Qd7 13.Qxa6 dxe4 14.0-0 exd3 15.Rd1 Qe6 16.Qxd3 Kf7, when Black would have simply been down a pawn.

The Jerome Gambit has a way of making opponents think that moving on to the next game might be a good idea...
