Jerome Gambit Refuted by A 1140 Player

I have enjoyed email from players around the world who have discovered the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). Some send games and analysis, which I always find helpful, even when it labeled, as a recent missive from Michael Dunagan, "Jerome Gambit refuted by a 1140 player: Me".

Let me share his note, as well as my response. (He sent position screenshots; I have replaced them with the underlying moves and my standard diagrams.)

Hi,

I first learned of the Jerome Gambit when YouTube suggested GM Amen Hambelton's episode.

I have been looking at it for four days since I first was shown it:

Essentially, I think Black just slips into a "Fried Liver" Defense with 6...Ke6, and it's good night ladies.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6

I do not have a chess engine but I thought White's best response is 7.f2-f4 attacking Black's Knight on e5.

7.f4

I guess chess.com has a little "scoreboard" to the left of the board.  The scoreboard likes 7...d7-d6 for Black. 

7...d6

White does get a Knight back with 8.f4xe5 and after 8...d6xe5  9.O-O controls the "F* file.

8.fxe5 dxe5 [Here White cannot castle, as suggested.]

If the White Queen checks instead with 7.Qh5-f5+, the King saunters to d6, 7...Ke6-d6 8.f2-f4 Qd8-e7.  Gotta take the Knight before it moves away to safety 9.f2xe5,  with the reply Qxe5 offering a.trade of Queens.

[From second diagram, above] 7.Qf5+ Kd6 8.f4 Qe7

Whether White trades Queens or not, he does not get Black's Dark Square Bishop, at least not in the opening as I have seen in other lines of play.

White would love to Castle but the c5 Bishop controls g1, the King's landing square.  White could "harrass a check" on f8, but as the Black King electric slides to c6, now she is under attack from the c5 Bishop and she must retreat with 4 escape landing spots: d8, f1, f3 f5 where the latter put the trade in play again.

I intuitively, down a Bishop for a Pawn, save the Queen with escaping to f3.  Chess.com agrees with this is the beat for White with (-5.38) as opposed to going back to e5 offering a trade (-6.25).

++++++

And now we are some 7-9 moves from the opening and white is going to have its head spin on how fast Black will develope with move like Ng8-f6 closing the "F" file and doubling up pressure on the d4 Pawn.

The best I could do for both sides

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qe7 9.fxe5+ Qxe5 10.Qf8+ Kc6 11.Qf3 Nf6 12.Nc3 d5 13.d3 Bg4


And now white has to trade Queens in order to not drop the pinned e4 Pawn.

Needless to say that chess.com believes this position is scores at (-5.81) or just short of a rook and a pawn or just short of two minor pieces.

And after this position,  I cannot find any chess.com good scoring moves for White.  I would think knocking the Black  bishop around with h2-g4 so a Queen side Castle would be good but it only increased Blacks score on chess.com...

Regards,

Michael P. Dunagan



Hi Mr. Dunagan,

Thank you for taking the time to analyze the Jerome Gambit, and then share what you have found with me.

It must have taken a good bit of time and effort to put all of that in, from your phone. I appreciate the effort.



It is not clear from GM Ambleton's hysterically funny video that I never said the Jerome Gambit was a great opening, or even a good one. Of course, my blog is approaching its 3,000th post, so there is no way that Aman would ever have read it all...😊



I do admit that I waited to the 5th blog post, back in 2008, to mention Henry Joseph Blackburne's fantastic crush of the Jerome Gambit:  Amateur - Blackburne, London, 1884 (0-1, 14). Most likely, if anybody has ever heard of the Jerome, they have seen this beauty.

It was probably blog post #17 when I first asked the question, "But - Is this stuff playable?" You might be surprised that my response was an immediate 
Of course not. The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) has many refutations. I'm glad that's settled.
However, I wasn't finished.

     Maybe a more useful question would be --
     Under what conditions might the Jerome Gambit be playable?


     In casual or blitz games among "average" players , perhaps -- when Grandmaster Nigel Davies' words from his Gambiteer I (2007) are relevant:
Having examined literally thousands of club players’ games over the years, I have noticed several things:
1) The player with the more active pieces tends to win.
2) A pawn or even several pawns is rarely a decisive advantage.
3) Nobody knows much theory.
4) When faced with aggressive play, the usual reaction is to cower.
That is the gist of my work, right there. I was led by the question "Who is this Jerome guy, and why are they blaming this terrible opening on him?" The answers were fascinating.

I have published on my blog every refutation that I have found, and would be happy to publish yours. I have published almost every Jerome Gambit that I have played (I keep finding a few I missed) - won or lost. Especially lost.

While examining the history of "Jerome's Double Opening" I discovered something curious: there are players who have won a majority of their games with the Jerome Gambit, despite its refuted status. Some (including me) have won over 75% of the time. That's downright weird.

So, the blog also became an exploration for me into what I called "errors of thinking". I was fascinated: how did anyone ever lose to the Jerome Gambit?

All the while, people all over the world have sent me their games. Mostly club players - but some stronger players, too. I now have a database of Jerome and Jerome-related games containing over 62,000. Only 15,256 come directly from the line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, but that's still more than I ever thought I would find.

I think it's fun to have a chess "secret weapon". As defenders get stronger and wiser, the Jerome Gambit becomes, more than ever, a school for tactics. Sometimes, a school for defense. Always, a school for being aware of opportunities. At some point, the Jerome brings more pain to the user than it does to the defender, and it will be set aside.

Whew. That was a bit long. I would love to share with you my specific thoughts on your analysis, but I think I've taken up enough of your time right now.

Again, thank you for the work you have done. I look for the whole story of the Jerome Gambit, not just the dashing wins.

Best wishes,

Rick

Let me also add that Mr. Dunagan has also sent me "Improving the Jerome", but I am going to hold off on that one for a while.

Jerome Gambit: Ghosts in the Defense


Recently I received the following Jerome Gambit game. At first, I did not know what to make of it.

Anonymous - Anonymous
5 3 blitz, lichess.org, 2020

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Nf6 9.Qxd8 White won



That was kind of strange... Except, a couple of days later, the same line played out in another game, a 3 0 blitz, although the defender struggled on for a dozen more moves before resigning.

How to explain Black's 8th move? A weak chess player? A hurried-by-the clock chess player? A scared-by-the-Jerome-Gambit chess player? An overconfident-and-therefore-inattentive chess player?

I finally decided that I had been onto something when I wrote "Half a defense is worse than none at all..." a decade ago.

My guess is that 7 out of 10 players who have ever heard of the Jerome Gambit had been exposed to Amateur - Blackburne, London, 18841.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Qh4 9.O-O Nf6 10.c3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4#



What if the defenders in both recent games remembered only a part of Blackburne's defense, or remembered it incompletely?
"Hmm... silly Jerome Gambit... accept the sacrificed Bishop... accept the sacrificed Knight... give back a Rook... trap the enemy Queen with my Kight - No, wait, I was supposed to play 8...Qh4 first!!"
I found an earlier game with even more pain.

KONB - elmflare
standard, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+Nxe5 6.Qh5+ g6 7.Qxe5 
d6 8.Qxh8 Qh4 9.O-O Nf6




This time the Queen is trapped, but take note of White's next move. Meanwhile, Black repeats Blackburne's killer attack on the King, including sacrificing another Rook, and his Queen. 

10.Nc3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4+ 15.Nxe4 Black resigned



White's Knight on c3 - instead of a pawn, as the Amateur played against Blackburne - ruined Black's fireworks display.

So, is 10.Nc3 White's way out of his Blackburne nightmare?

Actually, a game played at the end of May of this year said: No!

flash_ahaaa - thefinalzugzwang
2 1 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Qh4 9.O-O Nf6 10.Nc3 




10...Bh3 11.Qxa8

Best might have been 11.Qxf6+ Kxf6 12.gxh3 Qxh3, with a Rook, a Knight and a pawn for his Queen, although Black would still be better.

11...Qg4 12.g3 Qf3 White resigned



Surprisingly enough, Grandmaster Larry Evans had discussed this line in his Chess Catechism (1970). He gave 10...Bh3 a "!". In discussion on this blog, "GM Larry Evans and the Jerome Gambit", Bill Wall pointed out 10...Ng4, that elmflare played, above.

(Is 10.Qd8!? the real solution to White's trapped Queen? That's a long story, and one that will have to wait for another day.)

Jerome Gambit: And, In Time, The Win

In the following game, Black denies his opponent the wild attack that often comes with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). White soon has the better game, and, in time, the win.

M4G1CK - HubRekt
lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




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



Now, Black has 7...d6, the Blackburne Defense (named after the game Amateur - Blackburne, London, 1884, in which Blackburne sacrificed 2 Rooks and his Queen), or 7...Qe2, Whistler's Defense (named after Lt. G. N. Whistler, who played it in a correspondence match against Jerome).

Instead, he chooses what I have begun to call the Jerome counter-gambit.

7...Bxf2+ 8.Kxf2 Qf6+ 9.Qxf6+ Kxf6 



The good news for White is that he is no longer down a couple of pieces - in fact, he is up a pawn.

The bad news is that he doesn't have a dashing, smashing attack. He will have to grind out the win, starting in a Queenless middlegame.

10.Rf1 Kg7 11.Kg1 d6 12.d4 Nf6 13.Nc3 Re8 14.e5 dxe5 15.dxe5 Rxe5 16.Bf4 Rf5 17.Bxc7 Rxf1+ 18.Rxf1 Bg4 



White plays on without risk.

The only "danger" he faces is the possibility of a drawish Bishops-of-opposite-colors endgame, should the Knights and Rooks come off the board. That is not going to happen, though, as he is ready to win a piece.

19.Be5 Rf8 20.Nd5 Re8 21.Bxf6+ Kh6 



White has enough to win. It will take a few more moves.

22.Rf4 Bh5 23.g4 g5 24.Rf5 Bf7 25.Bxg5+ Kg7 26.Bf6+ Kh6 27.Bg5+ Kg7 28.h4 Bxd5 29.Rxd5 h6 30.Bd2 Re4 31.Bc3+ Kh7 32.Rd7+ Kg6 33.Rd6+ Kh7 34.Rd7+ Kg8 35.Rg7+ Kf8 36.Rg6 h5 37.gxh5 Rxh4 

You can see how the game is going to end.

38.h6 Kf7 39.Rg7+ Kf8 40.h7 Re4 41.Rxb7 Rg4+ 42.Kf2 Rh4 43.h8=Q+ Rxh8 44.Bxh8 Kg8 45.Rxa7 Kxh8 



46.Rd7 Kg8 47.c4 Kf8 48.c5 Ke8 49.Rd1 Ke7 50.c6 Ke6 51.c7 Ke5 52.c8=Q Ke4 53.Qc4+ Kf5 54.Rd5+ Ke6 55.Qc6+ Ke7 56.Rd7+ Ke8 57.Qc8 checkmate



Slow and steady wins the race. Nice.

Jerome Gambit: Largely Overlooked by History


I wanted to share another eronald (of lichess.org) game for a number of reasons. He faced one of the more challenging defenses to the Jerome Gambit, he selected a line of play that was recommended over 140 years ago - and which has been scarcely played at all. This game also allows me to tuck in a note from my research that comes from I-do-not-know-where. 

eronald - ayushsankar1006
5 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 

This can lead to either the Blackburne Defense, 7...d6, or Whistler's Defense, 7...Qe7. Both are complicated and each can be dangerous for the unwary. 

My preference to play, and not to face, is Whistler's. See "More (Update): Whistler's Defense" for a discussion.

7.Qxe5 Qe7 8.Qd5+ 

The highly dangerous (for White) 8.Qxh8 appeared in Jerome - Norton, D., correspondence, 1876 (1/2 - 1/2, 20) and Jerome - Whistler, correspondence, 1876 (0-1, 15). Jerome was fortunate to gain a half point from the two games. The December, 1876 issue of  American Chess Journal, commenting on the Whistler game, recommended 8.Qd5+ without analysis.

Then 8.Qd5+ practically disappeared from the face of the earth. Perhaps it should be referred to as Jerome Gambit Secrets #12 ?

I have in my notes something from a 2020 1 0 bullet game at
lichess.org - the players are not named
If played correctly 7.Qxe5 Qe7 8.Qd5 + Kg7 9.d4 Bb4 + 10.c3 Nf6 11.Qe5 Bd6 12.Qxe7 + Bxe7 13.f3 White plays one piece, and for the second they have more space and two pawns - you can still play very much (position on the interactive whiteboard), both on the one and the other side. Although, objectively speaking, Black has a win, but you need to make fairly accurate moves, let's recall the game of the unforgettable Mikhail Tal - how many could hold their position after the Tal victims, who turned out to be objectively won in the home analysis?
It is not every day that you see the Jerome Gambit and the Magician from Riga mentioned in the same paragraph! 

Of course, Tal has already been mentioned on the blog: see "The Evans-Jerome Gambit Returns (Part 1)" and "Correctness".

8...Kf8 


If, instead, 8...Kg7, the game continued 9.d4 Bb6 10. Bg5 Nf6 11.e5 Nxd5 White resigned, levigun - obviously, GameKnot.com, 2004. This is the only other 8.Qd5+ game in The Database.


9.O-O c6 10.Qc4 d5 11.exd5 cxd5 




12.Qf4+ 

White declines the pawn (12.Qxd5), as Black could then develop his Bishop or Knight, attacking the Queen with tempo. 


12...Nf6 13.d4 Bd6 14.Qd2 Qe4 




This looks a bit odd, although Black retains his advantage.

Given that this was a 5-minute blitz game, and taking into consideration Black's previous move, perhaps he was planning to set up the Bishop + Queen battery, but at the last second, noticed that 14...Qe5 would drop Her Majesty?

15.Re1 Qh4 16.Qh6+ Qxh6 17. Bxh6+ Kf7 18. Nc3 Ng4 



ayushsankar1006 continues to press his attack, even with Queens off of the board. Both players now ignore the pawn at h2 for a short while.

19.Bg5 Be6 20.Nb5  

Perhaps planning to allow the h-pawn capture, and then trap the Bishop with g2-g3, while limiting where the prelate could otherwise retreat to? Or, was the clock ticking? In any event, 20.h3 was probably the move to make. 


20...Bxh2+ 21.Kh1 a6 


The fly in the ointment. The Knight is invited to leave.

22.Nc7

Likely the clock.


22...Bxc7 23.f3 White resigned
