Jerome Gambit: Gratitude



The following Jerome Gambit game contains the kind of slip that happens in blitz or bullet.

The proper response for the first player - even if the move comes as a surprise - is one of gratitude.


feritTurkey - w4urae

2 1 bullet, lichess.org, 2024

1.e4 e5 2.Bc4 Nc6 3.Nf3 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Be7 


If you are playing the Jerome Gambit, expecting 7...Qe7 or 7...d6, and you encounter this move, do not despair.

The move may come as a surprise, but it is a pleasant one. The Database has 72 examples, with White winning 78% of the time.
 
8.Qxh8 

Black resigned

White is ahead the exchange and two pawns. If Black had planned to put his Bishop on f6 to protect his Rook (or attack the enemy Queen) it is already too late.

Jerome Gambit: Unusual

 


A dozen and a half years ago - in the first year of this blog - I learned of an unusual line in the Jerome Gambit.

Of course, back then, I mentioned the Pausen variation here, but I was not prepared to see how many regular Jerome Gambit players would eventually encounter it: angelcamina, Babypawnmonster, chessriddler, drumme, DutchLiLi, HauntedKnight, Littleplayerparis, perrypawnpusher, UNPREDICTABLE, Wall, ZahariSokolov, ZeKnightRider - and more.

The following game is Matthew_Slater's second such encounter.


Matthew_Slater - SeattleSeahaksfan

1 0 bullet, Chess.com, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5. Nxe5+ Ke7 

This is not a strong reply, but in a 60-second game, taking the game off of the beaten path is often worth it, because of the thinking time that it costs an opponent.

As we shall see, the tactic was only partially effective.

6.Qh5 Bxf2+ 

I am impressed by SeattleSeahaksfan's play. Stockfish 16.1 sees this return of material as best. No other game in The Database has this move.

7.Kxf2 Qf8+ 8.Ke1 Nd4 

9.Nc3 

Cold-blooded - and correct.

9...Nxc2+ 

It is not likely that, with an eye-blink's worth of thought, Black would have found 9...Nf6, driving the enemy Queen back to protect the square his Knight was attacking, 10.Qd1, then further ejection with 10...d6 11.Nf3 Bg4. White would be a pawn better, in that line; while in the text, the Rook on a1 is poisoned. 

10.Kd1 Nxa1 

In for a penny, in for a pound.

11.Nd5+ Kd6 12.Nc4+ Kc5 


Things are not looking good for Black's King.

13.Nxc7+ 

This move holds the promise of winning the Rook at a8, but there was also 13.b4+ Kb5 14.Nc3+ Kxc4 15.Qb5+ Kd4 16.Qd5 checkmate - not easy to catch in a bullet game. 

Now White gathers material.

13...Kc6 14.Nxa8 d6 15.Qd5+ Kd7 16.Ne5+ Ke7 17.Nc7 Bd7 18.Nxd7 Kxd7 19.Nb5 Ke7 20 Qxd6+ Kf7 

21.Qd5+ Kf6 22.Nd6 

Tightening the noose. After the game, he likely found 22.Rf1+ Kg6 23.Rxf8 Ne7 24.Qf7+ Kh6 25.d3+ g5 26.Rxh8 Ng8 27.Qxh7# 

22...Kg6 23.Nf5 Kf6 24.Qd6+ 


It is clear that Black's King will not escape.

24...Kf7 25.Qxf8+ Kxf8 26.Ke2 Kf7 27.d3 Ke6 28.Be3 Ke5 29.Rxa1 b6 


This has to be a nod toward the clock, as White's extra piece and two passers are enough to win easily.

30.d4+ Kxe4 31.b4 Kxf5 

Okay: Tick tock, tick tock...

32.a4 Ke6 33.a5 bxa5 34.Rxa5 a6 35.Rxa6+ Kd5 36. b5 Kc4 37.Ra5 Kb4 

38.b6 

The text is based on the idea that White's Rook can be jettisoned as his pawn races ahead. Just so - although the assessment overlooks the other side of the board.

With a few more minutes' thinking time, he would have found 38.Ra8 Kxb5 39.Rc8!?, when Black's Knight is pinned, his Rook is tied down to the Knight, and his King is cut off from stopping the advance of White's d-pawn.

38...Kxa5 39.b7 Ka4 

The clock ticks for Black, as well.

Seeing that he cannot catch the pawn, the King runs away from the future Queen, overlooking 39...Nf6, which would uncover the Rook and save the day.

40.b8=Q Ka3 41.Bd2 Ka2 42.Qb4 Ka1 43.Bc3+ Ka2 44.Qb2 checkmate

Jerome Gambit: Playing the Most Popular Moves?!



I have been having a lot of fun watching the many You Tube videos by Kaspa Chess.

Exploring different chess openings, move-by-move, the presenter follows the line of play most popular in the lichess.org database. 

I thought that I would give the same approach to the Jerome Gambit, so I visited lichess.org and began entering the opening's moves.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5

It turns out that each of these moves were the top choice.

4.Bxf7+

Well, this is only the 8th most popular move at lichess.org, but that's how we get the Jerome. 

By the way, the lichess database has over 800,000 Jerome Gambit games.

4...Kxf7

A full 97% of the games included this capture.

5.Nxe5+ Nxe5 6.Qh5+

Each move was the overwhelming favorite. No surprise.

6...Ng6

This is the top choice, 50% vs 19% for 6...Ke6. That was a bit of a surprise to me, but, I guess 6...Ke6 and 6...g6 (18%) are more committal.

7.Qxc5

Okay, I like the "nudge" 7.Qd5+ before capturing the Bishop, to displace the King to where it might interfere with the development of his Rook - but that is the second most popular choice at lichess.org.

7...d6

Easily #1.

8.Qd5+ Be6 9.Qxb7

White now has 3 pawns for his sacrificed piece, but I have always labelled this line of play with a "Caution" sign.

9...Nf6 10.d3 Re8

Black's move is barely more popular than the second choice, 10...Rf8 (857 games vs 844).

11.O-O Kg8

King safety is easy to understand.

12.Bg5 h6 13.Bxf6 Qxf6 14.Qxc7 Qxb2

Pawn grabs are not just for White.

15.Nd2 

15...Qxc2

What in the world??

We are down to only 12 games in this line in the lichess.org database, after 15.Nd2, and the text is the most popular response, really - 3 games.

16.Qxc2 Black resigned


And that is how the line at lichess.org ended, along with the games mulong28 - xJO3Yx, 1 0 bullet, lichess, 2021 and hassankondri - pradhanguru1982, 5 0 blitz, lichess.org, 2022

Jerome Gambit: The Bishops Bounty



Well, I am somewhat late to the party, as the post apparently went up on February 4, 2025, but it is still important to mention The Bishops Bounty website, with its massive amount of chess information, most especially, their post "The Jerome Gambit: Free Ultimate Guide to History, Tactics & Modern Mastery (With Curated Resources)" - a fantastic resource for anyone interested in 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

  • 🔥 Debates on its effectiveness in modern chess
  • 🏆 Famous Jerome Gambit games that left audiences speechless

Whether you’re a thrill-seeking player or a chess historian, this is your roadmap to mastering (or mocking) the opening that turns “quiet games” into firefights. Let’s ignite the board.

The site is very well done, and I tip my hat and bow to its creator. It is certainly the thing that I should have created - were I that skillful.

Go visit. But, be careful, there is so much content there to grab you, time will fly by while your are enjoying the visit.

Jerome Gambit: Short Story



Some Jerome Gambit games are like short stories, often with a moral. The following game is a good example.

ZeKnightRider - DenisDurand

5 0 blitz, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Ke7 5.Bxg8 Black resigned


According to The Database, Black scores 33% after declining the Bishop with 4...Ke7, vs 44% after accepting the Bishop with 4...Kxf7. YMMV.

Sometimes White playes 5.Nxe5, instead of 5.Bxg8, complicating things and hoping to enter regular Jerome Gambit lines a move up, if Black eventually plays ...Kxf7

The text solves in a simple way the "question" of White's Bishop - trade it off. Checking for the final position in The Database, there are 19 games, with White scoring 89%.

The moral is, meet 4...Ke7 with 5.Bxg8 and get on with things, e.g. 5...Qxg8 (better than 5...Rxg8) 6.Nc3 (no examples in The Database) d6 7.Nd5+ Kd8 8.d4 when Stockfish 16.1 sees White as about 2 3/4 pawn better.

Jerome Gambit: It's Good to Know



A journey to the Jerome Gambit can occasionally be diverted by the defender to the Two Knights game, although there are still dangers for the second player, as the following game shows. 

rincincinzio - LordOptimusPrimus

1 0 bullet, 2025

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


We have been here before. In "Impatient vs Inattentive"

Stockfish 16.1 evaluates this position as about a pawn worse for White than it evaluates 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ for White. 

This game brought "impatience" to mind again. I had touched on the topic as recently as 3 months ago, in Jerome Gambit: Impatience 

Four years ago, in the blog post "Unasked Questions" I looked at the Two Knights line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ and commented 

This line doesn't have a name, as far as I know, but it might as well be "the impatient Jerome Gambit". The earliest game that I have with it in The Database is from 2001, but it has to be much older than that. My research is lacking here.

Subsequently (see "Jerome Gambit: Facing Up to 4.Bxf7+ in the Two Knights [Part 2]"), thanks to Dr. Timothy Harding's UltraCorr 3A (2010) collection of correspondence chess games, I uncovered Draper, Dr - Child, AW., Belfast - Dublin team correspondence match-2 1891-2, an earlier game with that "impatient" line.

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Nc6 7.e5

Now 7...Be7 or 7...d5 will be best for Black.

7...Nd5 8.Qf3+ Kg8 9.Qxd5 checkmate

Checking The Database, it appears that rincincinzio has won 20 games with this line.

Jerome Gambit: Messy vs Clear



The following game shows the impact of both messy situations - and clear ones.

White, clearly, wins.


Wall, Bill - Smart

internet, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Nc6 

8.Qc4+ 

Or 8.Qd2, as in Wall,B - 1063314, lichess.org, 2017 (1-0, 26) and Wall,B - Guest10755845, PlayChess.com, 2018 (1-0, 23); 

Or 8.Qd3 as in Wall,B - Number555777, lichess.org 2017 (1-0, 23), Wall,B - Guest7503555, PlayChess.com, 2017 (1-0, 36) and Wall,B - Aliwael, internet, 2021 (1-0, 21); 

Or 8.Qd1 as in Wall,B - PerGranBom, lichess.org, 2017 (1-0, 24). 

8...Kf8

Or 8...Ke8 as in Wall,B - Kas55, lichess.org, 2016 (1-0, 17) 

9.O-O

Or 9.Bd2 first, as in Wall,B - Guest7127865, PlayChess.com, 2019 (1-0, 28).

9...Nf6 

Or 9...Qf6 as in Wall,B - Guest526975, PlayChess.com, 2016 (1-0, 18); or

9...Ne5 as in Wall,B - Guest616903, PlayChess.com, 2020 (1-0, 16).

10.Nc3 Ne5 11.Qb3 d6 12.f4 Neg4 

Black starts his attack.

13.h3 Nh6 

Sharper was 13...h5!? 14.hxg4 hxg4.

14.Be3 Qd7 15.g4 


This is a calculated risk - one that succeeds.

15...Qe6 

Black avoids the messiness of 15...Nxg4 16.hxg4 Qxg4+.

16.Qxe6 Bxe6 17.g5 Nh5 

He should have gone for more mess, again, with 17...Bxh3.

18.gxh6 gxh6 19.f5 Rg8+ 20.Kf2 Bc4 

21.Bxh6+ Kf7 22.Rfe1 Rg3 

23.Be3 

Also 23.Re3

23...Rxh3 24.Rh1 Rxh1 25.Rxh1 Nf6 26.b3 Ba6 

The position seems less messy - but Stockfish 16.1 now assesses it as 3 3/4 pawns better for White.

I don't know how Bill keeps doing this.

27.Bd4 Ng4+ 28.Kf3 Ne5+ 29.Bxe5 dxe5 30.Rxh7+ 

30...Kf6 31.Nd5+ Kg5 32.Rxc7 Rh8 

Black's pieces are active, but they are out-numbered.

33.Rg7+ Kh6 

White now has a forced checkmate.

34.Rg6+ Kh5 35.Nf6+ Kh4 36.Rg4+ Kh3 37.Rg1 Kh2 38.Rg2+ Kh1 39.Ng4 Rh4 40.Nf2 checkmate
