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!

Jerome Gambit: Daily Chess



I enjoyed checking out the Jerome Gambit tournament played in September 2020 at the DailyChess site.

Players bramble, Greg Williams, Jim Dandy, karlconroy, and Norfolk and Good battled it out.

Greg Williams, karlconroy, and Norfolk and Good each finished the first round with 5 wins, and advanced.

In the second round, karlconroy prevailed with 2 more wins, giving him the top score.

Well played, all. 

I have added the games to The Database.

Jerome Gambit: Extremely Rare



Stumbling onto the simplifychess website, I discovered the following entry for the Jerome Gambit

The Giuoco Piano: Jerome gambit is extremely rare and occurs in less than 1 in 10,000 games. From the data, you can expect that White will only have a 39.13% chance of winning, while Black should have a very high 60.87% chance of winning. Since most players have probably never seen this opening and because White has such a low expected chance of winning, it may be well worth it to keep this variation in your back pocket. If you are Black you should have a significant edge and will probably catch your opponent off guard.

Fascinating

I do not know the reference database for the above statistics, but I checked my Big Database (2016) and there were 10 Jerome Gambits out of 6,466,290 games: 0.00000154648, far less common than the above, by an order of magnitude. On the other hand, White scored 3 - 5 -2, which is 40%, very much in tune with the above.

No wonder the Jerome Gambit often surprises the defender.

Jerome Gambit: Keep Up, or Lose on Time



angelcamina (you have seen his games on this blog before) likes to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) at bullet speed - one minute per game, no increment.

His opponents sometimes just lose to the strength of the attack. Other times, they work to "solve" the Jerome, but this takes time off their clock, so they slip and drop material and lose. Or, they simply run out of time. 

Here is a recent game, with a couple in the notes, to see how it's done.

A good idea, both helping development and attacking (thus, limiting) White's pawn center.

Black has done very well, but it does not matter, as here White won on time. Bullet chess can be cruel.
