Jerome Gambit: Help Me Out, Bro

In the chaos that is the Jerome Gambit, mistakes by the opponent, especially in faster time controls, almost feel like a helping hand to the attacker.

The Italian Four Knights Jerome Gambit

5...Kxf7 6.Ng5+

This tempting kind of check can be seen in The Face Palm Variation and The Improved Face Palm Variation.

In this case, The Database has 1,523 games, with White scoring 33%.

6...Kg6 

Safer is the retreat 6...Kg8. Black is still better after the text move, but his willingness to take chances with his King is troubling.

7.h4 h6 

Black kicks the Knight, but he would have done better to stop the enemy's h-pawn with 7...h5.

The consequence is checkmate.

8.h5+ Kxg5 

Or 8...Nxh5 9.Qxh5+ Kf6 10.Nd5 checkmate

Want to play one of the craziest attacking openings in chess? The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+!?)

Jerome Gambit: Don't Go There

 

The above position arises when White, in a variation of the Jerome Gambit, allows his Queen to yield to temptation and deliver a check from the back rank. 

The warning against such a thing, with an explanation, is given in "Jerome Gambit: Developing (Part 1)"

Why a warning?

The Database shows 48 games with the line, with White scoring 31%  (14 - 32 - 1).

Frankly, I am surprised that I don't have a game in that pile.

Some players are willing to brave the line, however - once. For example, Babypawnmonster, with 69 games in The Database, scoring 57%, gave it a try.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Qf6 8.Qe8+ 

                                   

8...Qe7 

The superficial attraction of 8.Qe8+ is that it looks like Black will need to find an alternative to the check-block 8...Ne7, because that would lose a Rook.

This is an illusion, as the Knight move is the strongest for Black -

8...Ne7 9.f5+ (9.Qxh8 Qh4+ 10.g3 [10.Kd1 Qg4+ 11.Ke1

Qxg2 12.Rf1 Nf3+ 13.Rxf3 Qxf3] 10...Qg4 11.Rf1 Nf3+ 12.Rxf3 Qxf3 13.f5+ Kf7 14.d4 [14.d3 Nxf5 checkmates] 14...Qxe4+ 15.Kd1 Qxd4+ 16.Bd2 Qg1+ 17.Be1 Bf2 18.c3 d5 19.Qxc8 [19.g4 Qxe1+ checkmates] 19...Qxe1+ 20.Kc2 Rxc8) 9...Kd6 10.Qh5 (10.Qxh8 Qh4+ 11.Kd1 Qg4+ 12.Ke1 Qxg2 13.Rf1 Qxe4+ 14.Kd1 Qg4+ 15.Ke1 Qh4+ [15...Nf3+ 16.Rxf3 Qxf3 17.d4 Qe4+ 18.Kd1 Qxd4+ 19.Nd2 Qg4+ 20.Ke1 Nxf5] 16.Kd1 Qg4+ 17.Ke1 b6) 

Still, in the game, Black's 8...Qe7 is good and continues his advantage.

9.f5+ Kf6 10.Qh5 d5 11.d4 Bxd4 

Oh, my!

It is necessary to remain alert to tactics, even in a winning position. Play should go something like 11...g6 12.Bg5+ Kg7 13.Qh4 Nf6 14.dxc5 and Black is doing well. 

12.Bg5 checkmate

Another example of "the equalizing injustice of chess" (Edward Lasker, 1913).

More of Tim Harding

 

Having mentioned Tim Harding in the earlier  post, "Family Resemblance" - looking at openings related to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) - I would like to share a bit more about his writing.

Tim Harding, Bishop's Opening, (1973)

After 1.e4 e5 2.Bc4 Nf6 3.Nf3 Nxe4 Harding wrote

The possibility of 3...NxP [3...Nxe4] was recognized by such early nineteenth cenury theoreticians as Jaenisch and Staunton, who belieed however that White simply go the advantage by 4.BxP+ [4.Bxf7+], disturbing Black's king position at no material cost. But Morphy was to show that this sort of position is ooften favourable to the second player (e.g. the famous Meek - Morphy game in the Scotch Gambit) since he is left with central control and the two bishops and can usually perform a slow castliing. This lesson was slow to be learned, however, 4.BxP+ still being seen some 30 - 40 years after Morphy's retirement.

Tim Harding, Vienna Game, (1976)

Of 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 (or 1.e4 e5 2.Bc4 Nf6 3.Nc3 Nxe4)

Harding wrote

the violence in the play was such that "a game between Dracula and the Frankenstein Monster would not seem out of place."

The name of the variation stayed, as you can see in the image, above, of Eric Schiller's Frankenstein-Dracula Variation (1999).

Written about the line related to the Jerome Gambit, note the move evaluations

T. D. Harding, G.S. Botterill, The Italian Game (1977)

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 NxP!? 5.BxP+?

From which we might conclude that the line is exciting, but not sound. Truly does sound like a Jerome Gambit relative!

Jerome Gambit: Return Is Not Enough

The following game demonstrates that returning some of the material sacrificed in the Jerome Gambit is not, in itself, enough to provide a win to the defender.

What I call the Anti-Bill Wall Gambit, seen in "Jerome Gambit: A Cautionary Tale", "Jerome Gambit: Another Reason", and, most recently, Jerome Gambit: The Anti-Bill Wall Gambit, Return to Discussion (Part 1 & 2), leads to an equal position.

(Bill has almost 1,900 games in The Database, scoring 89%)

8.Kxf2 Ng6

This is Stockfish 17.1's 5th choice. White now has the advantage.

Family Resemblance

From time-to-time I cover in blog posts some openings that might be considered "relatives" to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

More than the Semi-Italian Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.O-O Bc5 5.Bxf7+), the Italian Four Knights Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+), or the Semi-Italian Four Knights Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 h6 5.Nc3 Bc5 6.Bxf7+).

The Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+) is also one to come to mind. I first covered that line 8 years ago.

There is also the Noa or Monck Gambit, (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Nxe4 5.Bxf7+), arising from the Two Knights Game.

I am not sure that I have presented what Tim Harding has called the Frankenstein Dracula Variation (1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4), coming out of the Vienna opening, and that can heat up with 4.Bxf7+.

I might have to give that last one a closer look.

Jerome Gambit: Hungry Hungry Hippos

I was tempted to start this post with a quote from "Sleeping in the Gutter or Getting Away?"

He who captures the Queen's Knight pawn sleeps in the gutter -- a stern warning against pawn-grabbing

He who grabs the pawn, and spirits away, lives to fight another day -- a lesson from Bill Wall's Jerome Gambit 

Then, I was reminded of the children's game, "Hungry, Hungry Hippos" and thought it humorously represented the actions of Bill's Queen in gobbling up pawns.

Wall, Bill - Benjamin

internet, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ 

Bill is 17- 0 - 1 with this move - all the more interesting when you consider that Stockfish 17.1 evaluates the position as 3 1/4 pawns better for Black. 

6...Ng6 7.Qxc5 d6 8.Qd5+ 

This Queen check shows up in Bill's games, the earliest being Wall,B - Guest4395, Microsoft Internet Gaming Zone, 2001 (1/2-1/2, 17).

Black is asked about his b-pawn.

8...Be6

8 of Bill's games saw this move 

9.Qxb7 Nf6 10.Nc3 Qe7 

White has 3 pawns for his sacrificed piece.

He needs to be careful about his Queen, and he needs to respect Black's piece advantage on the Kingside.

11.O-O Ne5 

This "kick me" move challenges White in that he will have to choose: d-pawn or f-pawn?

12.d4 

Stockfish 17.1 (33 ply) agrees.

12...Neg4 

Mounting an attack.

He might consider taking advantage of the placement of the enemy Queen: 12...Rhb8 13.Qa6 Bc4 14.Qa4 Bxf1 15.dxe5 Qxe5 16.Kxf1 Qxh2 17.Qc4+ Kg6 18.Qd3 Qh1+ 19.Ke2 Kf7

13.f3 Nh6 14. Bxh6 gxh6 

15.d5 Bd7 16.Qxc7 

The Queen's pawn-grabbing makes me nervous, but Stockfish reassures that White is slightly better.

16...Rhc8 

It is time to punish Her Majesty for playing a game of Hungry Hungry Hippos, but is Black up to the task?

17.Qa5 a6 18.Rae1 Bb5 19.Rf2 Nd7 

The Knight effectively traps its own Bishop, which Bill reacts to immediately.

20. a4 Bc4 21. Nd1 Nc5 22.Ne3 Ba2 23.Ra1 

23...Kg8 

It is interesting that the computer treats Black's Bishop's excursion as a problem of tempo, i.e. 23...Bb3 24.Nf5 Qf6 25.Qb6 Rab8 26.Qxd6 Bxa4 27.Rxa4 Nxa4 28.Qd7+ Kf8 29.Qxa4 Qxb2 30.Qxa6 Qb6 31.Qxb6 Rxb6

analysis diagram

The analysis diagram shows that White would have 4 pawns (4 connected passers!) for the exchange.

24.Rxa2 Nd7 25.Nf5 Qf6 26.Qd2  Ne5 27.Qxh6

Black resigned

The second player does not have compensation for five pawns.
