Jerome Gambit: Daily Grind

Cartoon frabulator gauge

The following game tests White: Can he switch his plans from a smashing, crashing attack on the King to a sedate, grind-it-out middlegame?

TCNB - Jerry_89
3 0 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 Bxf2+ 


I have seen this move a lot, lately. Black wants to get the Queens off of the board, and is willing to return the sacrificed material - plus a pawn interest - to do so. White must change his expectations from an early attack on the King to winning a slow, methodical pawn-up Queenless middlegame.

8.Kxf2 Qh4+ 9.g3 Qf6+ 10.Qxf6+ Nxf6 11.Nc3 d6 


White will get enough play if Black captures the pawn, i.e. 11...Nxe4 12.Kg1+ Kg7 13.d3 Nf6 14.Nc3 d6 15.Bg5 Rf8 16.Bxf6+ Rxf6 17.Rxf6 Kxf6 18.Nd5+

12...c6 13.d3 Bg4 14.Rf1 Kg7 15.Bf4 d5 


Often in the Jerome Gambit the move ...d5 helps Black, but in this case it is overridden by tactical issues.

Jerome Gambit: Don't Spill the Popcorn


The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is like a thrilling action movie - played at high speed (5 minute blitz). It would be rude to interrupt the flow of the game with too many comments like "better would be..." or "less troublesome would be..." Better to watch the game unfold. Don't spill the popcorn.

10.Nd5 
Qe6 11.Qf8+ Kc6 12.Qxg7  Nc4 13.d3 



The position on the board is a mess, but, perhaps Black has an edge?

13...b5 14.f5 

Take the Rook, instead. 

14...Qe5 15.Qxe5 Nxe5 16.Bf4 d6 17.O-O-O

17...Bb7 18.c3 Kd7 19.d4 Nc4 20.dxc5 Bxd5 21.Rxd5 Nf6 22.Rd4 Rhe8 23.cxd6 cxd6 



With 3 pawns for the sacrifice piece, White has about equalized, especially when considering the safety of each King.

24.e5 Ng4 25.e6+ Ke7 26.b3 Nce3 27.Bxd6+ Kf6 28.h3 Nf2



At about this point, the clock seems to become a factor.

29.Rf1 Rad8 30.g4 Rxd6  31.Rxf2 Nxg4 32.hxg4 h5 33.gxh5 Rexe6 34.Rxd6 Rxd6

The smoke has cleared. White has this one.

Jerome Gambit: More Fun Quick Finishes


Some evenings I work late into the night, researching and analyzing, trying to find the elusive path to bringing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) a step or two further away from "just another refuted opening" and a step or two closer to being a "real" opening. (See "Jerome Gambit: Pinocchio" and "Jerome Gambit: Velveteen Rabit Part 1".)

Then, in the next morning's email, I get another handful of games with notes like "This is my first Jerome Gambit, ever, and I totally crushed the guy!" and I realize that the Jerome is not about finally becoming a boring, normal opening.

The Jerome Gambit is about playing chess and having fun.

So - here are some more quick hits that recently arrived.

The checkmate in the following game never gets old. We have seen this kind of thing before, and we will, no doubt, see it again.

GraysonTheHoff - tengodosperras

The Jerome Gambit can inspire the sacrificial tendency in other openings, too. Jerome Sicilian, anyone?

1.e4 c5 2.Bc4 Nc6 3.Nf3 a6 4.Bxf7+ Kxf7 5.Ne5+ Nxe5 6.Qh5+ Kf6 7.Qf5#



Here, the Petroff Defense, by transposition, meets the Jerome Gambit. Any guess which wins?

I don't know a lot about playing the Jerome against the Hungarian Defense, but players are kind enough to teach me.

My daughter bought me Murray Chandler's How to Beat Your Dad at Chess. I am sure she meant no harm. The following game could have wound up in that book. I hope the son didn't get grounded.

Finally, a Jerome Gambit that ended when the defender realized that his defense hadn't really defended.

Jerome Gambit: Danger!



In the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Black's King is drawn into the wilderness, where he has a slim path to safety - but he misses it. White demonstrates the danger. 

NN - NN
10 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5. Nxe5+ Nxe5 6.Qh5+ Ke6



7.Qf5+ Kd6 8.Nc3 Qf6

Black's Queen joins the defense, but the King is going to be drawn into danger, anyhow.

9.d4 Bxd4 10.Nb5+ Kc5 11.Nxd4 Kxd4 12.Be3+ Kc4 13.Qh5 Kb4 


The King is all alone and at risk.

He needed to play 13...Kb5, instead, and focus on returning home. For example, if White then tried 14.f4, there was the helpful 14...d6, giving a way off the battlefield, via c6 and d7. He shouldn't worry about 15.fxe5 Qxe5, as he can afford to return the piece and remain a piece ahead. 

14.Qe2 

Cutting off retreat. White now focuses on checkmate. It is well worth playing through the following moves, to see what choices the attacker had, and what chances the defender did not.

14...Qc6 15.c3+ Ka4 16.b3+ Ka5 17.b4+ Ka4 18.Qd1+ Kb5 19.a4+ Kc4 20.Qd4+ Kb3 21.Rb1+ Kxa4 22.b5+ Qc4 23.Rb4+ Black resigned

Black will lose his Queen, and then his King.

Jerome Gambit: Catching Up


With many new chess players discovering the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7) and this blog, there is an opportunity to learn a great deal more about the opening, the person who created it, and the people who play it.

But, do you have to go back to the beginning - "Welcome!" - and read almost 3,000 blog posts?? No, of course not.


If you have an interest in a particular player, or a particular topic, or even a particular move, you can always use the "Search This Blog" function, on the right. Searching a string of moves, say "4.Bxf7+ Kf8 5.Bxg8 Kxg8" can also be effectively done with general search engines like Google or Bing, which will turn up links to this blog.

You can also visit the "Retro" page, which has easy links to pages of interest, with lots of information.

Or you can take the multi-part Jerome Gambit quiz, starting here.

There is a page, with links, that discusses the timeless, but relevant question, "Is the Jerome Gambit playable?"

Finally, for a deep dive into the Jerome Gambit, you can read the multi-part article that I wrote for Stefan Bücker's chess magazine, Kaissiber. He tried and he tried and he tried to make the article fit, but I think the Jerome was a bit too irregular for him.

Jerome Gambit: More Mysteries


Jerome Gambit games keep pouring in...

Another mystery (see "Jerome Gambit: Ghosts in the Defense") arrived the other day, followed, a few days later, by, yet, another. I want to share the games, and some perspective. I have made the name of the players of the Black pieces anonymous.

1. e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 

Black resigned

What was going on??

Three things, about the world of the Jerome Gambit.

I wanted to share something from GM Nigel Davies' fantastic book, Gambiteer I.
“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 might explain the defender's behavior.  Meanwhile, to explain the attacker's attack, some input from Geoff Chandler, chess player, coach, and raconteur. I quote from one of his posts
Here is a one-move blunder table showing how severe the blunder needs to be in a game between two players of the same grade.

All players should be able to spot their opponent leaving a mate in one on. 
A 1200 player should win if an opponent blunders a Queen or a Rook. But not necessarily if they pick up a Bishop or Knight. 
1500 players often convert piece-up games into a win, but this is not the case if a pawn or two up. 
An 1800 player usually wins if they are two pawns up. 
In a game between two 2000+ players a blundered pawn is usually enough to win.
I think that Chandler's blunder table can be applied to time limits, as well. In correspondence play, a little material means a lot. In blitz or bullet play, though - sacrifice away!

Finally, an assessment from the Jerome Gambit player, himself, concerning the first game, although it could apply to the second as well.
The game started off with a normal Jerome Gambit. After ...Nxe5 I decided to go for the Queen check variation rather than the theoretically more solid d4 move forking the bishop and knight, mainly because I consider it to be a more active way to attack the king and eventually gain compensation for the sacrificed pieces. As soon as I checked the king with my queen, black started burning some serious time which suggests that this gambit might have caught him by surprise which is in my opinion the biggest advantage of the Jerome Gambit together with its fierce attack on the king side. As you can see in the game I sent you he eventually burned approximately 1 minute and 25 seconds, only in his sixth and final move. Which shows that the spontaneous nature of the gambit is its main advantage, as if this had been a quick 3 minute blitz game where this gambit is originally intended to be played, he would have already used half of his time in his first six moves. My opponent was probably considering the best way in which he could get out of check. He eventually decided to block the queen's check with his knight going for ...Ng6 probably because he was scared of playing something like ...g6 which would run into Qxe5 delivering a fork on the bishop and rook, or protecting his knight with a move like ...Ke6 which would expose his king in a very dangerous way. After my opponent played ...Ng6 both protecting his knight and blocking the check I decided to play Qd5+! which is as you already know the theoretical novelty that GM Aman Hambleton introduced in his video about the Jerome Gambit which has the idea of inviting black to play either Kf8 or Ke7 which allows white to capture the bishop with another check to continue his attack and to stop black from developing. Surprisingly enough, shortly after I played this move my opponent resigned because despite being objectively better, as he was two pieces up, he thought that he was losing because of the speed in which I played my moves which suggested that the Jerome Gambit was either some kind of tactic which he had blundered into or a very strong attack which I had brought prepared from home. The moral of the story is that he resigned a six move game being two pieces up and with plenty of time on the clock solely because of the speed of my moves and the position of his king...

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.

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!

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.)
