Jerome Gambit: Valuable Time (Part 1)



Playing a lot of Jerome Gambit games (770, counting all varieties) should be helpful to my play - and it often is.

The notes to the following game hint at how much I was assisted by my experience.

I hope they boost the play of Readers as well.

perrypawnpusher - JAMARTINO

Not only the Italians play the Italian, Chess.com, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 

From "A Jerome Look At The Semi-Italian Opening (Part 1)"

On this blog I refer to 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 as the Semi-Italian Opening, a name given to it in Chess Master Vs Chess Amateur (1963), by Max Euwe and Walter Meiden. Here is what the authors say about Black's third move (I have changed the notation from English descriptive to algebraic.)

This is a favorite move of the weaker amateur. He fears some future attack by the White QB (Bg5, for instance) or by the White KN (Ng5), and, before the White QB is even able to move, he plays the precautionary 3...h6. In certain positions, such a precautionary move is occasionally necessary, but in this position, not only is it not necessary, but it consumes valuable time. This puts Black one move behind White in the type of opening where tempi are of greatest importance. Instead of meeting the enemy's rapidly mobilizing forces with armed soldiers (i.e., by bringing out his pieces), Black only loses time and force, and, without realizing it, even weakens his defensive wall...

When an ex-world champion player points out that 3...h6 "consumes valuable time," it is worth remembering.

A gambit player benefits from "valuable time".

4.O-O 

It is true that d2-d4, either now or on the next move, transposing into a Scotch Game or Gambit, is a bit better than the text; but I wanted to transpose into the Jerome Gambit.

4.O-O has been my overwhelming choice here.

I tried 4.Bxf7+ a couple of times but do not recommend it: perrypawnpusher - marapr, blitz, FICS, 2007 (1-0, 27) and perrypawnpusher - anonymous, casual over-the-board game, 2014 (1-0, 14).

Also, I tried 4.Nc3, once, although it transposed after 5.O-O: perrypawnpusher - gmann, blitz, FICS, 2011 (1-0, 36).

4...Nf6 5.Nc3 Bc5 6.Bxf7+ 

The Semi-Italian Four Knights Jerome Gambit. 

The Database shows I have played it in 60 games, scoring 79%. 

6...Kxf7 

Accepting the Bishop is natural and good, although, some time back, I had an opponent decline with 6...Kf8, and then do it again a year and a half later. See perrypawnpusher - Duquesne, blitz, FICS, 2010 (1-0, 21) and perrypawnpusher - Duquesne, blitz, FICS, 2012 (1-0, 21). 

7.Nxe5+ Nxe5 

There is no solid reason to avoid capturing on e5, except, perhaps, psychological, but I have to admit that I once stumbled against 7...Kg8 in perrypawnpusher - roccovargas, blitz, FICS, 2011 (0-1, 22) and once against 7...Kf8 in perrypawnpusher - ojot, blitz, FICS, 2012 (0-1, 15).

(Yes, sometimes I do regret committing to sharing all of my games - good, bad, and ugly.)

8.d4 


The "Jerome pawns" begin to strike back.

Jerome Gambit: Reorientate


The following game reminds me of chess advice

“If you have made a mistake or committed an inaccuracy there is no need to become annoyed and to think that everything is lost. You have to reorientate yourself quickly and find a new plan in the new situation.”
– David Bronstein

angelcamina - MarcelVogel118

1 0 bullet, lichess.org, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 


This position is at least as old as Jerome - Brownson, Iowa, 1875 (1-0, 28).

7.Qd5 +Ke8 8.Qxc5 d6 9.Qc4 


angelcamina has played 16 games that reached this position, scoring 63%.

9...Qe7 10.Nc3 Ne5 11.Qe2 Nf6 


Black is better, with a piece for two pawns, but his King remains at risk - something that could be remedied if he could now castle, but that is no longer possible.

12.d4 Ng6 

Instead, 12...Nc6 was more forcing, because White's Queen no longer defends the d-pawn.

13.O-O Kf7 14.f4 Re8 

15.e5

The "Jerome pawns" begin their advance.

15...dxe5 16.fxe5 Kg8 

Completing his castling-by-hand, but better - leading to an even game - is returning the sacrificed material with 16...Nxe5 17.dxe5 Qxe5 18.Qf2 Bd7 19.Bf4 Qh5 20.Rad1.

17.Qc4+ 

White could have played 17.exf6 with advantage, but it is a lot to calculate (17...Qxe2 18.f7+ Kh8 19.Nxe2 Rf8 20.d5 Ne5 21.b3 Rxf7 22.Bb2 Bf5 23.Ng3 Bxc2 24.Bxe5 Re7 25.Bf4) versus getting Her Majesty out of the line of fire, with check.

The text move works because of the time control.

17...Be6 18.d5 Nxd5 

Instead, the retreat 18...Qd8 would have won a piece.

19.Nxd5 Bxd5 

See the note, above.

20.Qxd5+ Kh8 


The position is settling down.

21.Bd2 Qxe5 22.Qxe5 Nxe5 23.Bc3 Ng4 


The text move allows White to grab the initiative again.

24.Rf7 Rg8 25.Rxc7 Rac8 26.Rxb7 Rcd8 27.Re1 Rde8 28.Rxe8 Rxe8 29.Bxg7+ Kg8 30.Bc3 

30...Ne3 31.Rxa7 Nxc2 32.Rg7+ Kf8 33.Rxh7 Re1+ 34.Kf2 Re7 35.Rxe7 Kxe7 36.g4 Ke6 37.h4 White won on time

Jerome Gambit: Rely On the "Jerome pawns"



In the following game, White relies on the pawns that he has to overcome whatever advantage Black might have by having an extra piece.

angel_camina - Dreamscape1

Chess.com, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.O-O Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ke6 

8.c3 

White played this one move later, in angelcamina - hamed1988h, 1 0 bullet, lichess.org, 2023 8.Qf5+ Kd6 9.c3 Qf6 10.Qh3 Nf7 11.d4 Bb6 12.e5+ Nxe5 13.dxe5+ Qxe5 14.Rd1+ Ke7 15.Bd2 Kf8 16.Qf3+ Nf6 17.Re1 Qd5 18.Qg3 d6 19.c4 Qxc4 20.Bc3 Bd7 21.Bxf6 gxf6 22.Nc3 Qc5 23.Rad1 Qxf2+ 24.Qxf2 Bxf2+ 25.Kxf2 Black resigned

8...g6 9.Qh3+ Kf7 10.d4 d6 

11.Qg3 Bxd4 

Black returns some of the sacrificed material.

White activates his "Jerome pawns".

12.cxd4 Nc6 13.d5 Ne5 14.f4 Ng4 15.h3 N4f6 16.Nc3 Nh5 17.Qf3 Kg7 

18.g4 Nhf6 19.e5 Nd7 

Too passive. Counterplay with 19...h5 - even at the cost of another piece - was the right way to go.

20.e6 Ndf6 21.g5 Nh5 22.f5 hxg5 23.fxg6 Nf4 24.Bxf4 gxf4 25.Qxf4 


White is clearly in control.

25...Nf6 26.Rf3 c6 27.Raf1 Rf8 28.Qh4 cxd5 29.Rxf6 Rxf6 30.Qh7+ Black resigned

Jerome Gambit: Knowledge Grows From Experience


The ability to play quickly (see "I Don't Know How They Do It") is one advantage in playing the Jerome Gambit.

Another is the ability to play from experience.

Concerning the following game, it is helpful to know that White has played 375 Jerome Gambits at Chess.com.

It shows.

yoooooooooooooooo1 - VicomteDeTurenne

3 0 blitz, Chess.com, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

7.Qxe5 Qe7 

Alonzo Wheeler Jerome used this defense in three of his games, all wins, against Daniel Jaeger, in their 1880 correspondence match.

8.Qf4+ Nf6 9.d3 h6 10.Qxc7 d6 11.Qa5 


White's Queen has grabbed a third pawn to compensate for his sacrificed piece, but the first player's lag in development requires care.

11...Ng4 12.O-O Qh4 

Taking advantage of the enemy's Queen's wandering.

13.h3 Bxf2+ 14.Kh1 Ke8 15.Bf4 


Coming to the King's aid.

Black exchanges the piece off, but that comes with an unexpected weakness - the kind of thing that can happen in a 3-minute game.

15...Bg3 16.Bxg3 Qxg3 17.Qh5+ 

Her Majesty switches sides of the board, claiming the advantage.

17...Kd7 

Not much better is 17...Kd8. The text allows the exchange of Queens.

18.Qxg4+ Qxg4 19.hxg4 Kc6 20.Nc3 Bxg4 


The smoke has cleared, and White has an extra pawn, the better pawn structure, and an open line for his Rooks.

21.Rf7 Rhg8 22.Raf1 Be6 23.Re7 Bd7 24.Rff7 Rad8 25.Rxg7 Rxg7 26.Rxg7 


This is the point where some annotators would say "the rest is just a matter of technique".

26...Rf8 27.Kg1 b5 28.Nxb5 Kxb5 29.Rxd7 Kc5 30.Rxa7 Kd4 31.Rd7 Ke3 32.Rxd6 Ra8 


The play has the feel of being affected by a ticking clock.

33.a3 Rb8 34.b4 Rc8 35.c4 Rh8 36.b5 h5 37.b6 h4 38.b7 h3 39.gxh3 Rg8+ 

40.Kh2 Rf8 

I suppose that Black could have tried the cheapo 40...Kf2, threatening Rook checks at g2 and g1, forcing a draw.

However, given the steadiness of White's play up to this point, I don't think that would work, as the simple 41.Rf6+ would show. 

41.Rc6 Rf2+ 42.Kg3 Rf3+ 43.Kg4 Rf8 44.Rc8 


There is not much left for the defender, save a spite check or two.

44...Rf4+ 45.Kg5 Rf3 46.b8=Q Kf2 47.Rf8 Black resigned


A business-like game, from start to finish.

I Don't Know How They Do It



I continue to be impressed by chess players who can manage both an unusual chess opening line and the bullet time control.

And win.

I mean, I could easily play a few meaningless moves and lose on time. I know how to do that.

But in the following game HenriDepraz brings home the full point - with checkmate - in under 10 moves.


HenriDepraz - ls103

1 0 bullet, lichess.org, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5 

I looked at this move in the first year of this blog, 2008

Of course, White can now simply play 4.Nxe5, but what's the fun in that? 

My most comprehensive coverage was in "Jerome Gambit: Again the Early Sources"

Looking again (see "Jerome Gambit: Early Sources") through Peter J. Monte's The Classical Era of Modern Chess (2014) I noticed that the Jerome Gambit-related line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5 4.Bxf7+ (see "Offside" for starters) has appeared as early as in Rodrigo "Ruy" López de Segura's Libro de la invencion liberal y arte del juego del Axedrez (1561) and Giulio Cesare Polerio's Ordini di giuochi degli scacchi in diversi modi, cosi di mano, come sottomano, cio e in offenza, e dife[n]za co[n] altri bellissimi partiti, sono di Guilio Cesare Polerio alias l'Apruzzese. Giocandosi del Pari (1594).

 Monte writes

1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5: Mentioned in Lopez III, xiv, the move 3...Na5 is refuted by the sequence 4.Bxf7+ Kxf7 5.Nxe5+ etc. in Polerio's D16 and 29.

The early lines of play are given

1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5

Last move in Lopez III, xiv. 4.Bxf7+ Kxf7 5.Nxe5+

* 5...Ke7 6.d4 d6 7.Bg5 Nf6 8.Nd3 h6 9.Bh4 g5 10.Bg3 Bg4 11.f3 Bh5 12.Qd2 in Doazan D16

* 5...Ke6 6.Qg4+ Kxe5 7.Qf5+ Kd6 8.Qd5+ Ke7 9.Qxa5 and

* 5...Ke8 6.Qh5+ Ke7 7.Qf7+ Kd6 8.Qd5+ Ke7 9.Qxa5 in Doazan D29

"Doazan" refers to Gabriel Eloy Doazan's 1843 article in Le Palamede, where his "Un manuscrit sur les echecs" presented one of Polario's manuscripts. 

4.Bxf7+ 

There are 2,860 games with this move in The Database. White scores 71%.

4...Kxf7 5.Nxe5+ Ke8 


Black's King steps back.

Stockfish 16.1 slightly prefers 5...Ke7, e.g. 6.d4 d6 7.Bg5+ Nf6 8.Nd3 h6, when play gets wild - 9.Qh5 hxg5 10.Qxh8 Nxe4 11.0-0 Bf5 but supposedly equal, where White has a Rook and a pawn (and a safer King) for two pieces.

6.d4 

Simple enough.

With only one minute on the clock, White does not explore 6.Qh5+ g6 7.Nxg6 hxg6 8.Qxg6+ Ke7 9.d3 Bh6 10.Bxh6 Nxh6 11.Qg5+ Kf7 12.Qxa5 with four pawns (and a safer King) for a piece. 

6...d6 

Encouraging - or overlooking - White's next move.

7.Qh5+ Ke7 

Black would have better chances to hold on with 7...g6 8.Nxg6 Nf6 9.Qh4 hxg6 10.Qxh8 Nxe4 11.Bh6 Qf6 12.Qxf8+ Qxf8 13.Bxf8 Kxf8 when White would have a Rook and two pawns for two pieces. 

8.Qf7 checkmate

There are 7 games like this in The Database

Jerome Gambit: Complications, Complications, Complications


I continue to be amazed how players like angelcamina can find their way through the complications of the Jerome Gambit to gain the full point - all with only seconds of thinking time per move.

angelcamina - Gregigras

1 0 bullet, lichess.org, 2026

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


Open Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 Qe7 


angelcamina has reached this position 22 times, scoring 14 - 6 - 2. 

9.O-O Nc6 10.Qc4+ Qe6 11.Qe2 


White has some work ahead of him to get things going.

11...Nd4 

It is always tempting to harass the enemy Queen. This move does not squander Black's advantage, but it reduces it.

12.Qd3 c5 13.f4 a5 

Planning to develop a piece to a6?

14.e5 


This is a complicated position to solve in a 1-minute game!

Black's best might be to return a piece while adding more tactical complexity - 14...b6 15.exf6 Ba6 16.f5 Qe5 17.Qh3 Bxf1 18.fxg7 Qxg7 19.Qh5+ Kg8 20.Kxf1 Nxf5 - ending up an exchange ahead.

15.Nxd5 Qxd5 16.c3 Rf8 

Stockfish 16.1 gives a line that keeps things even - 16...d6 17.cxd4 Qxd4+ 18.Qxd4 cxd4 19.Bd2 dxe5 20.fxe5+ Ke6 21.Rad1 Bd7 (21...Kxe5 22.Bf4+) 22.Rf4 Ba4 23.Rc1 Rhd8 24.Rc7 Bc6 25.Rxg7 Rg8 26.Rxg8 Rxg8 27.Rxd4 Rxg2+ 28.Kf1 Rxh2 29.Bc3.

Of course, the computer can calculate very rapidly.

17.cxd4 cxd4 

Safer was exchanging Queens after 17...Qxd4+.

18.Be3 

To win the d-pawn.

With more time, White would have found that he could grab a different pawn, with 18.Qxh7 Ke8 19.f5 Qg8. 

18...b6 19.Qxd4 Qe6 

It still was safer, instead, to exchange Queens.

20.f5 Qc6 21.Rac1 Qb7 22.Qc4+ Ke8 

23.f6 gxf6 24.exf6 Rf7 

The only way to put off checkmate was 24...d5.

25.Bf4 d5 26.Rce1+ Kf8 


27.Bh6+ Kg8 28.Re8+ Rf8 29.
Rxf8 checkmate
