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.

14.f5 dxe5 15.dxe5 Nxe5 16.Re1 Kf6 

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

17.Rxe5 Kxe5 18.Qd5+ Kf6 19.Ne4+ Ke7 20.Bg5+ Nf6 21.Nxf6 gxf6 22.Re1+ Kf8 23.Bh6 checkmate

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.

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.

7.Qd5+ Ke8 8.Qxc5 Qe7 9.Qe3 d5 

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

10.d3 dxe4 11.dxe4 Nf6 12.f3  

He has also played 12.Nc3 c6 13.O-O Kf7 14.f4 Re8 15.e5 Nd7 16.b3 Qc5 17.Qxc5 Nxc5 18.Ba3 b6 19.Bxc5 bxc5 20.Ne4 Rd8 21.Rae1 Rd2 (ouch) 22.Nxd2 Ba6 23.Rf2 Rd8 24.Ne4 Rd4 25.Nd6+ Ke6 (understandable, but it was safer to retreat) 26.f5+ Kd5 27.fxg6 hxg6 28.Nf7 g5 29.Nxg5 Re4 30.Rxe4 White won on time, angelcamina - Rakammerer80, lichess.org, 202l.

17.c4 Qa5 18.Kb2 Rd7 19.e5 Nxe5 20.Ne4 Rxd1 21.Ng5+ Kg6 22.Rxd1 

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

Jerome Gambit: Beware Free Hugs

I was recently challenged to a game by an online player new to, and excited about, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). He took White, and I decided to play my favorite defense, although, in retrospect, I could have chosen something that would have allowed him to bash me all over the board...

Anyhow, I probably should have suggested "Jerome Gambit: What About the Rook?" as pre-game precautionary reading.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 

This move often leads to either the Blackburne or Whistler Defense, and in either case there will be a dangerous offer of a Rook.

7.Qxe5 Qe7 

Whistler's Defense.

8.Qxh8 

I have touched upon the dangers of this move in the aptly titled post "There Are Some Risks We Should Not Take."

8...Qxe4+ 9.Kf1 Qh4 

I recommended this move in a blog post about 6 years ago. According to The Database it has been played only twice, since, with effect.

A couple of years ago I saw it in analysis in one of the Hindi Chess Videos - see "Jerome Gambit: Interesting Sideline".

10.g3 Qh3+ 11.Kg1 Qe6 

A blunder, after which the game should only be drawn. Instead, 11...b6 (or 11...b5) would lead to checkmate, once Black's Bishop gets on the a8-h1 diagonal.

Also seen:

11...b512.d4 Bb7 13.Qxh7+ Qxh7 14.Nd2 Qh3 15.f3 Bxd4 checkmate, ZahariSokolov - ekwador, FICS, 2017. 

12.Kg2 

I was shocked to see this move (the time control was 3 days per move, so the play was not continuous) because I had set the position up wrong, and thought that my opponent had played 11.Ke1, not 11.Kg1.

Instead of the text, White had 12.Qxh7+ Kf8 13.d4, forcing Black to consider a draw by repetition, e.g. 13...Qe1+ 14.Kg2 Qe4+ 15.Kg1 Qe1+ etc. Otherwise, Black can play on, down the exchange and a pawn.

Now Black can force checkmate.

12...Qe4+ 13.Kg1 

Or 13.Kf1 Qxh1+ 14.Ke2 Qe4+ 15.Kf1 d5 16.Qxh7+ Kf8 17.Qxc7 Qh1+ 18.Ke2 Bg4+ 19.Kd3 Qf3 checkmate

Or 13.Kh3 d5+ 14.g4 Qxg4 checkmate

13...Qe1+ 14.Kg2 Qxf2+ 15.Kh3 d5+ 16.Kh4 Be7+ 17.Qf6+ Bxf6 checkmate

Now, I get to play the Jerome. I wonder what defense he will play?

Happy Birthday to Me

Sharp-eyed Readers may have noticed that I have recently changed my photograph in the "About Me" section of this blog. The sweatshirt is a birthday gift from my son, Jon, and daughter-in-law, Himani. So, when it comes to the Jerome Gambit, I not only wear my heart on my sleeve, I gladly wear the moves on my chest.
