Jerome Gambit: Easy for You, Difficult for Me



The following game is an interesting example of how complicated a Jerome Gambit attack can become. White wins a miniature, while the computer grumps in the notes. The checkmate is very nicely executed.


Wall, Bill - Guest1352598

PlayChess.com, 2021


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5. Nxe5+ Nxe5 6. Qh5+ Ng6 

7.Qxc5 d6 8.Qd5+ 

This move poses the question to Black: Is developing the Bishop worth the b-pawn? (After all, the Bishop will have to move again after f2-f4.)

According to The Database, ZahariSokolov at FICS has played this move 80 times. 

8...Be6 9.Qxb7 N8e7 


Better was 9...Nh4 as seen in Wall, Bill - CheckMe, Chess.com, 2010 (1-0, 23).  

Bill has also seen 9...Ne5 in Wall,B - Guest249301, PlayChess.com 2013 (1-0, 30).

10.O-O Re8 

Preparing to castle-by-hand. Stockfish 12 prefers the move subtle 10...Nf4 11.d3 Ne2+ 12.Kh1 Nxc1, winning the Bishop for the Knight. 

11.f4 Bd7 

Here the computer suggests 11...Qd7 12.Qa6 Kg8 13.f5 Nxf5 14.exf5 Bxf5 with an even game. It rejects 12.f5 because of 12...Bc4 13.fxg6+ Kxg6 14.d3 Reb8 winning the White Queen, with a small advantage for Black e.g. 15.Qxa8 Rxa8 16.dxc4 Qc6.

12.Qb3+ Kf8 13.f5 Ne5 14.d4 Nf7 


Black safeguards his Knight from those aggressive "Jerome pawns". 

Instead, he could have complicated things with 14...Rb8, and White could have responded with the equally complex 15.f6. Stockfish 12 sorts it all out as being kind of equal, but that's a computer for you - in real life, somebody would have tumbled into a bad position.

15.f6 gxf6 16.Rxf6 d5 


Black wants to block the Queen's deadly attack on f7. Sadly, this doesn't work.

The computer suggests more complications: 16...Nd5 17.Bh6+ Ke7 18.Rxf7+ Kxf7 19.Qxd5+ Kg6 20.Be3 Qe7 21.Nc3 c6 22.Qc4 Rf8 when White would have 3 pawns for the exchange, and the advantage.

17.Bh6+ 

You saw this, right?

17...Kg8 18.Qg3+ Ng6 19.Rxg6+ Kh8 20.Bg7+ Kg8 21.Bf6+ Black resigned

Jerome Gambit: Secret Attacking Idea



The popularity of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) among new and improving chess players has been growing, in large part because, I suspect, it provides a lot of tactical play swirled into a chaotic setting that is not familiar to the defender, and is definitely not "book".

Strong players can look on and mutter "tut-tut" but they can't escape the fact that the players are having a lot of fun.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


Black was feeling comfortable, having reeled off three moves of "theory", but now what is this?? Nobody has mentioned this before. Is this some secret attacking idea that he has overlooked?

A thousand gained rating points later, he would grab the Bishop and smile, saying "Show me!" - but first he has to get through this game. After all, White wouldn't give up a piece for nothing, would he?

4...Kxf7 5.Nxe5+ 

This makes no sense, sacrificing a second piece, but it feels... dangerous.

5...Nxe5 6.Qh5+ 


I knew he had something up his sleeve!

But, wait, can't I just punch his Queen in the nose?

6...g6 

There!

7.Qxe5 

One piece gone, but I can protect the other!

7...Qe7 


8.Qxh8 

Rats! I was afraid he would see that...

(Black has unknowingly stumbled upon Whistler's Defense, which offers a Rook for a violent, if somewhat complicated, counter-attack, starting with 8...Qxe4+! Today, however, White is unaware of the danger and is pleased to recover some more material.)

8...Ke6 

Yipes!

The enemy Queen has invaded my back rank! Escape! Escape!

9.Qxg8+ Kd6 10.Qd5 checkmate


What do you call that opening? It's brutal!

Jerome Gambit: A Distraction



Last year I received a game with an unusual defense to the Italian Game. I thought, at the time, that it had to be a one-off, but I discovered a handful of similar games in The Database, and another dozen or so related ones online.

I thought I would share some games, not because the defense is strong - or, as it turns out, something that stops a Jerome-ish reaction - but because it could be a distraction that could eat up thinking time in a blitz game.

1.e4 e5 2.Nf3 Nc6 3.Bc4 b5 


Here we go. I have not found a name for this line. It seems dubious - if a Jerome Gambit player can call any line "dubious".

I am not sure what the idea is, after the logical 4.Bxb5. I have seen continuations such as 4...a6, leading to an odd-style main line Ruy Lopez, and 4...Nd4, leading to an unusual Bird variation of the Ruy Lopez.

In any event, Readers can guess the response by White that I am interested in.

4.Bxf7+ 

Meeting a surprise move with a surprise move. Black does not have a vulnerable Bishop sitting at c5, but White's Queen can still add pressure.

4...Kxf7 5.Nxe5+ 


The Knight sacrifice is thematic and probably strongest, but also seen has been

7.Qxe5 Qe8 8.Qxh8 Black resigned


White admitted that he did not know why his opponent resigned here, and I have to agree with him: despite the lost Rook (he is down the exchange for two pawns), Black has a won game after 8...Qxe4+.

So, does that mean that 3...b5 is viable against 4.Bxf7+ ? Well, no. For starters, White went after the wrong Rook on move 8. He should have played 8.Qd5+ and then 9.Qxa8, with advantage.

If Black were to play 7...Nf6, White would have 8.Qxb5. The computers would still like Black, but White would have 3 pawns for his sacrificed piece, instead of the usual 2 pawns.

Likewise, White probably should answer 7...d6 with 8.Qxb5, as 8.Qxh8 would be risky as the Queen could be trapped and won, e.g. 8...Nf6 9.d3 Qe7 10.Nc3 Bb7 11.Bg5 Bg7 12.Qxh7 Rh8 13.Qxh8 Bxh8.

Jerome Gambit: The Greatest Invention in the Last Century



I stopped by the chessentials website the other day, and read a lot of interesting items. In particular, I enjoyed the thoughtful essay,


In Defence Of Elitism In Chess: 7 Reasons Why Elitism Accusations In Chess Are Vastly Exaggerated


I totally cracked up, however, when I got to the following - with its footnote.

I also believe they are not nearly as prevalent in any of the given fields, as it is sometimes presented. I think a large part of the blame for this eschewed perception goes to the greatest invention in the last century.

The Internet. 12

I checked out the footnote at the bottom of the article

12.Bonus points if you thought “The Jerome Gambit” was the answer. 

Awesome.

Jerome Gambit: Bishop Opening Trap



I stopped by the Chess Only website the other day. It has a lot of interesting chess content, including instruction about the game, as well as a variety of Openings and Opening Traps. There are also games of the top chess masters.

What caught my eye was the post on the "Bishop Opening Trap (Don't Touch My Bishop!)", featuring 1.e4 e5 2.Bc4 Nc6 3.d3 Na5 Bxf7+. There are six game examples given, and the themes in the game should be familiar to Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) players.

I have looked at the line in the early blog posts "Eric Schiller Doesn't Play the Jerome Gambit" and "Not Playing the Jerome Gambit Either". They are worth checking out for some background on the opening.

Here is short, violent affair presented at Chess Only.

Jerome Gambit: Everywhere



The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ) seems to be everywhere these days. Check out the game recently presented at TikTok. It features a very nice and deadly attack on the enemy King. The notes are by the winner. I have added the diagrams.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


The Jerome Gambit is a highly dubious line that involves sacrificing a piece for center control.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Nc6 8.Qxc5 Nf6 9.Nc3 


White's strategy is very simple, push the pawns and throw pieces at the king.

9...d6 10.Qc4+ Ke7 11.d4 a6 12.O-O Bd7 13.e5 Ne8 


White can exploit the fact that Black's king is stuck in the centre of the board.

Eventually I sacrificed the exchange for a king hunt that led to mate.

Jerome Gambit: Quite Something



There is an old phrase, "to damn with faint praise", which means to evaluate something, not as "fantastic" or "terrific" or "amazing", but, say, as "that's... uh... nice".

A while back I visited the online site of Australian Grandmaster David Smerdon, and commented on both his latest book, and my current fascination.

GM Smerdon was kind enough to respond.


Rick Kennedy says:

GM Smerdon,

I am working my way through your fascinating The Complete Chess Swindler, a topic that greatly appeals to me, from both a psychological perspective and as a matter of survival: I have been researching and playing the worst chess opening ever, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), for a couple of decades, and have come to realize that any success whatsoever has been due to swindles. (I immediately apologize to the ghost of Frank Marshall and other masters, living and dead.)
Many thanks for your hard work.



Hi Rick. I recently came across the Jerome Gambit on YouTube. It’s….quite something!
