Jerome Gambit: Not "Business As Usual"

When a defender looks for moves, treating the Jerome Gambit as just another opening can be a mistake. Plain, "business as usual", development is not enough.

The following game is a good example.

ryuugu-rena - Alexlll

3 0 blitz, lichess.org, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

ryuugu-rena has 1,205 games in The Database. He scores 59%.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 

This move often leads to either the Blackburne defense or Whistler's defense.

7.Qxe5 d6 

Blackburne, it is.

8.Qxh8 Be6 

This move is a bit "business as usual" in that it is not a response to the position on the board, it is simply developing another piece.

The Database has 54 games with this line, including games by Jerome Gambit regulars angelcamina, Arman-Avdalyan, DutchLiLi, fehim, intercrosse, Jagulep, jdpz, perrypawnpusher, petasluk, Wall, and ZeKnightRider. White scores  87%. 

9.Qxh7+ 

I was fascinated to see that early on in its analysis, Stockfish 17.1's top choice was 9.h4, although by 25 ply in depth it settled upon 9.d4.

The computer explored the dynamic 9.d4 Bb4+ 10.c3 Qh4, which looks, at first glance, to be threatening; but Stockfish 17.1 evaluates White as being about a Rook better, with the exchange and two pawns.

The game might continue 11.Nd2 Rf8 12.O-O Nf6 13.Nf3 Rxh8 14.Nxh4 Ba5 15.Re1 and White is better.

The move played in the game is fine.

Black tries to whip up some kind of attack, but in vain.

9...Kf8 10.Qxg6 Qh4 11.O-O Re8 12.d3 Nf6 13.Bg5 Black resigned

In a 3-minute game, these unfortunate things can happen.

Jerome Gambit: Stumbling My Way, But, Luckily, Not Falling

 

Giving "Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) odds" to a Chess.com bot, I stumbled my way to the following endgame position.

Black can not win, but should not lose. (After the game, Stockfish 17.1, at 83 ply, evaluated the position as 0.00.)

In fact, the game was a bit of a bother.

Although I was better from move 14 onward, I missed a Rook sacrifice at move 17 that would have led to checkmate; at move 21, I missed another possible Rook sacrice leading to checkmate in 4 moves; and, later, still, a Queen sacrifice at move 23, which would also have led to a checkmate in 4.

In the end, I had to trust my faithful "Jerome pawns" to, once again, see me through.

53.Kb4

Black's last pawn will fall, and then the question will be: Which is stronger, 3 pawns or a Bishop?

The defender's well-placed King holds the position for him.

53...Bf1 54.Kxa3 Be2

Simpler is 54...Bg2 55.Kb2 Bxc6 56.Kc3 Bxd7 and White's pawn will soon fall.

55.Kb4 Bg4 

This works, too.

56.a4 

The sad reality is that White's remaining pawn, after Black sacrifices its Bishop for the other two, will be a Rook pawn, which has its limitations. For example 56.Kb5 Bxd7 57.cxd7 Kxd7 58.Kb6 Kc8 59.a4 Kb8 60.a5 Ka8 - Black's King arrives in time to draw the game.

56...Bd1 

Or 56...Bxd7 57.cxd7 Kxd7 58.Kb5 Kc7 etc.

57.a5 

57...Bg4 

Black has allowed that pesky a-pawn to advance too far.

I can't explain how that happened. Bots still can have trouble in endgames?

It still had 57...Bf3 58.Kc5 Bxc6 59.d8=Q+ Kxd8 60.Kxc6 Kc8 61.Kb6 Kb8 or just 57...Be2 58.Kc5 Bf1. In both cases, the game is a draw.

58.a6 Be2 59.a7

One of the White pawns will Queen.

59...Kxc6 60.a8=Q+ Kxd7 61.Qd5+ Ke7 62.Qe5+ Kd8 63.Qxe2 Kc7 64.Qe6 Kd8 65.Qf7 Kc8 66.Kb5 Kd8 67.Kb6 Kc8 68.Qc7 checkmate

Jerome Gambit: And, Still, Not Yet...

 

Today, I was back, again, to the very informal chess club that meets at a local library every-other-week.

Alas: three games, three losses.

Even more disappointing: no Jerome Gambit.

I played the Black side of a Giuoco Piano, hoping my opponent would play the Jerome, but: no.

In two of the games (including a Sicilian Wing Gambit, Declined, in my one game as White) I was simply out-played.

In one game, I reached a Rook-and-pawns endgame, three pawns up - but inattentively allowed a back rank mate.😒

I did learn that there was such a thing as "duck chess". I had to look that one up, at chess.fandom -

Duck Chess is a chess variant invented by Dr. Tim Paulden in 2016. The game follows most regular chess rules but adds a dynamic component to the mix: a rubber duck that both players can move. The Duck blocks the square it's on, making it impossible for pieces to move to that square or through it (Knights may Jump over ducks). The duck creates a lot of new tactical possibilities (often called "quacktics") by unpinning pieces, blocking defenders, trapping pieces, and more. Duck Chess went viral in 2022 after popular content creator IM Eric Rosen played the variant on his stream. Other famous streamers like GM Hikaru Nakamura, WFM Anna Cramling, IM Levy Rozman, and more followed suit, further increasing the game's popularity. The duck has to move every turn.

Amazing... 

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.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 

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

9.d4 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.

Babypawnmonster - henbra

10 0 rapid, lichess.org, 2024

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!
