Jerome Gambit: Occasionally Buried



Sometimes I get so caught up in the Jerome Gambit and this blog that I forget that the large majority of chess players is unfamiliar with Alonzo Wheeler Jerome and 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

It is tempting to exaggerate my efforts (over 3,200 blog posts) and yield to temptation, as a couple of chess friends have suggested, and re-name the opening the "Jerome-Kennedy Gambit" - but that would be over-stepping some boundaries. Jerome deserves his Gambit.

As it is, there is plenty of confusion as to what the Jerome Gambit actually is. (I am not going to pick on Joseph Henry Blackburne today.)

I have found other openings labeled the "Jerome Gambit" - for example, the Salvio Gambit, which is a variation of the King's Gambit: 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.Ne5 Qh4+ 6.Kf1

Of course, there is also the Muzio Gambit: 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.0-0 (5.Bxf7+ is the Wild Muzio or Lolli Gambit) gxf3 6.Qxf3 Qf6 7. e5 Qxe5 when 8.Bxf7+ is considered the Double Muzio Gambit.

All of which can lead to confusion (as can the passage of time). Recently I read a couple of newpaper chess columns that did their best to bury or cloud the Jerome Gambit.

From the Pittsburgh Sun-Telegraph, April 25, 1950, in a story about a "New York Doctor's Chess Library Contains Rare Old Books", T. M. Cherington, the paper's Chess Editor, wrote

Next to the Alaine C. White collection willed to the Cleveland Public Library, the largest chess library in America is Dr. A. Buschke's at 80 East Eleventh St., New York City.

His library contains thousands of chess books in most languages and he is constantly buying new works...

Dr. Buschke has Kieseritzky's Cinquante parties jouees du Cercle des Echecs et au Cafe de la Regence, published in Paris in 1846. Kiesertizky developed the Jerome Gambit sacrifice of Bishop and Knight for Rook and Pawn which goes by many names like Cunningham Gambit and Rice Gambit...

This might come across as somewhat confusing, as the openings mentioned, except the Jerome, are all variations of the King's Gambit

The Kiesertizky Gambit goes 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.h4 g4 5.Ne5.

The Cunningham Gambit refers to 1.e4 e5 2.f4 exf4 3.Nf3 Be7

The Rice Gambit is 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.h4 g4 5.Ne5 Nf6 6.Bc4 d5 7.exd5 Bd6 8.0-0

 A few years later, in the Pittsburgh Sun-Telegraph of September 18, 1954, T. M. Cherington was at it again in his "The World of Chess" column

The Jerome Gambit and its many variants, such as the Muzio, the double Muzio, the mad Muzio, the Cunningham, the Kieseritzky and the Rice, so often proved unsound are showing themselves again in serious tournaments.This darling of 100 years ago has as its essence the sacrifice by the white side of Bishop and Knight for Black's Castled Rook and protected pawn. We can find no other reason for the resurgence of the Jerome than the search for novelty.

Hardly "the darling of 100 years ago", the Jerome Gambit made its debut in the pages of the Dubuque Chess Journal in 1874.

The reference to the sacrifice of "Bishop and Knight for Black's Castled Rook and protected pawn" is an especially egregious error, as the whole idea of the Jerome Gambit is to prevent Black from castling in the first place, with 4.Bxf7+

A Nice Jerome-Type Game

The following game was sent by a Reader who wishes to remain anonymous. I am tempted to create a pseudonym, like I did with "Cliff Hardy", but for now I will pass - I would love to call him the "Nameless Detective", but Bill Pronzini has already written a great series with that character.

Anyhow, instead of risking an aggressive attack after 1.e4 e5 2.Bc4 Nf6 3.Nc3 with 3...Nxe4 4.Qh5!? or 4.Nc3!?, Black essays a sort of reversed Ruy Lopez against White's Vienna Game (which becomes a Three Knights) - only to be, of course, Jeromed...

The comments are by Mr. A, the diagrams are by me.

 

Anonymous - Anonymous


1.e4 e5 2.Bc4 Nf6 3.Nc3 Bb4


4.Nf3 Bxc3 5.Bxf7+ 


5...Kxf7 6.Ng5+ Ke8 

A very safe move, although Stockfish 11 finds even a better one: 7...Kg8 (and 7...Kf8which is only slightly better then 7...Ke8 [on depth 32], but this is a "less human" move). 

In case of a "more adventurous" 6...Kg6, I found that I don't have to rush with taking the bishop: 7.h4 is very strong and Black is forced to play h5 (almost) immediately, because trying to save the bishop loses the game: 7...Bd4 8.h5+ Nxh5 9.Qxh5+ Kf6 10.Qf7+ Kxg5 11.Qf5# or 7...Bd4 8.h5+ Kxg5 9.d3+ Be3 10.Bxe3#, and 7.h4 Bb4/Ba5 is a mate in 15 moves (of course during the game I didn't see that it's even close to mate, but 8.Qf3 is very strong for obvious reasons). 

I said "almost", because there is a nice in-between move 7...Bxd2+ 8.Bxd2 (Black gives the bishop for the pawn, instead of giving it for free with dxc3).

7.dxc3 h6 8.Nf3 Rg8 


Black could have defended the pawn with 8...d6 (Stockfish's second favourite move, first one is 8...Nc6), but my opponent had a different idea: give up e5 pawn for capturing on e4. 

9.Nxe5 d6 10.Ng6 Nxe4 11.O-O c6 


12.Re1 Bf5 13.Qh5 Qf6 14.Nh4+ g6 15.Qxh6 Rh8


Here I could go 16.Qg5 or 16.Qg4, but 16.Nxf5 leads to a nice sac: a queen for a bishop, knight and a rook. Also, for Black's remaining rook and knight being out of the game for a long time. Definitely a worthy sacrifice. And it turned out that Stockfish agrees with me, 16.Nxf5 is the best possible move in this position.

16.Nxf5 Rxh6 17.Rxe4+ Kd7 18.Nxh6 b5 


According to Stockfish, this is a very weak move, but my reply also wasn't one of the strongest moves.

However, it was more relevant that I had a simple plan: just to activate all pieces, while for my opponent doing the same was probably even not possible.

19.a4 bxa4 20.Raxa4 Qh8 21.Bg5 Kc7 22.Bf4 


Stockfish sees 5 moves better then my 22.Bf4, but even this one is evaluated about +7, White is clearly winning!

22...Qf8 23.Re6 Nd7 

My opponent finally managed to move the knight, 8 moves after the sac. But it is too late (moreover the knight is poorly placed). And the rook is still out of the game.

24.Rd4 Qc8 


Because of the threat of Bxd6+ winning the queen. 

25.Rdxd6 Kb6 26.Rxg6 Qb7 27.Rg7 Rd8 


A total despair: the rook enters the game only to get attacked...

28.Bg5 Qa6 

The last Black's hope is 29...Qa1+ with a terrible mate in 3, but one

simple move vaporizes the threat.

29.h4 Black resigned 


Stockfish at depth 42 evaluates this position as +60.15.

Jerome Gambit: Piano Piano Update

 

The end of Round 1 for Group 6 is approaching in the Chess.com "Piano Piano" tournament.

Currently, I am leading the group with 14.5 points, with one game left to complete.

Right behind me is PasayDefence, with 13 points and one game left to complete.

Also with 13 points and one game left is ZlikoM.

The third player with 13 points and one game left to complete is Bossferreira.

Three of us will advance to the next round. 

The Jerome Gambit has been good to me, scoring 5 - 1 -1. (Technically, it scored 2 more wins, as one game was won on time after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ and another was won on time after 4...Kxf7 5.Nxe5.)

Jerome Gambit: I'll Take Your Word For It


When you are playing a bullet game of chess, it helps to be able to rapidly calculate variations and choose your move quickly - over and over again.With one or two minutes to work with, however, it is sometimes helpful to "cut analytical corners" and believe in the reliability of a particular move, because it fits into your opening, or because your opponent wouldn't have played it unless it fit into his defense: I'll take your word for it.

That is a useful lens through which to view the following game.


linganno - reimannhalf

2 1 bullet, lichess.org, 2021


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 


7.Qxc5 d6 8.Qh5 

One feature of the Jerome Gambit is early activity of the Queen. In fact, that is why Joseph Henry Blackburne referred to the opening as "the Kentucky Opening" in his book Mr. Blackburne's Games at Chess (1899) - there was at the time a line of play, 1.e4 e5 2.Qh5 which was called the Kentucky Opening.

In this game, White shows that he believes in the Jerome Gambit.

8...Nf6 

Skepticism.

9.Qf3 Re8 10.O-O Kg8


Black has castled-by-hand. I don't know how much experience he had with the Jerome, but with this move he takes White's word that it is tricky to deal with - otherwise he would have grabbed a pawn with 10...Rxe4.

11.Re1 Ne5 

Ah, yes, disbelief - which often shows up in If I can't think of anything to do, I will attack the Queen. Black overlooks 11...d5

12.Qg3 Nh5 

Nothing to this silly gambit.

13.Qc3 Bd7 


Still, maybe I need more development. I will put my extra piece to good use. Black overlooks the very strong 13...Qh4.

14.d4 Nf7 15.Qf3 Nf6 16. Bg5 h6 


All of a sudden Black is willing to take White's word for it, pulling his forces back, and even overlooking the possible 16...Nxg5

17.Bh4 Qe7 18.Nc3 Qe6 19.h3 Ng5 20.Bxg5 hxg5 21.e5


 The typical Jerome Gambit pawn break. You gotta believe.

21...dxe5

This move is okay, and many defenders feel required to make the pawn exchange, although in this case there was also the consistent 21...Bc6

22.dxe5 Nd5 

Black is fully under the sway of the Jerome Gambit: White is kicking my pieces around!

23.Qxd5 Black resigned


White is up two pawns, and his opponent takes his word that he can take it from there...

Jerome Gambit: A Complicated Affair (Part 3)

 [continued from the previous post]


perrypawnpusher - PasayDefence

"Piano Piano" tournament, Chess.com, 2020



What to do? What to do?

The forward f-pawn is going to fall. After some Rook moves, I decided to exchange my beloved "Jerome pawns" for my opponent's Queenside pawns.

32.Rc1  Kf8 33.Rc8+ Re8 34.Rc4 

I did not want to exchange Rooks, as I wanted a piece to help out on both sides of the board.

After the game, Stockfish 12 preferred 34.Rc3, but I am not sure why. Perhaps it was to anticipate the need to protect my h-pawn.

34...Ke7 35.b3 Kf6 36.Kf3 Kxf5 


37.Re4 Kf6 38.Rh4 h6 39.Rg4 g5 40.Re4 Ke7 41.Ra4 a6 42.Rc4 Bb8 


43.Rb4  Kd6 44.Rxb7 Kxd5 45.Rb6 a5 46.Rb5 Kxe6 47.Rxa5 Kd7 


Well, I had my connected passed pawns, but I could not see how to advance them safely, while protecting my Kingside.

48.Rb5 Kc6 49.Rf5 Re6 50.Ra5 Kb6 51.Rd5 Bd6 

It looked like my opponent was seeing a balanced game, too.

52.Rf5 Be7 53.Rd5 Bc5 54.Rf5 Bd6 55.Rd5 


After the game I asked Stockfish 12 if I could run my pawns. It said, Not Really: 55.a4 Be7 56.Kg2 Rd6 57.Rb5+ Ka6 58.Re5 Bd8 59.Re4 Ka5 60.f4 gxf4 61.Rxf4 Rd2+ 62.Rf2 Rd3 63.Rf5+ Kb4 64.Rb5+ Kc3 65.a5 Rd6 66.Kf3 Ra6 67.b4 Ra7 68.Rb8 Bg5 69.Rb6 Kc4 70.a6 h5 71.b5 Be7 72.Rb7 Rxb7 73.axb7 Bd6 74.Ke4 Kxb5 75.Kf5 Kb6 76.Kg5 Kxb7 77.Kxh5 and Black's Bishop will cover the Queening square for my remaining pawn. Draw.

55...Bc5 56.Rf5 Bd6 57.Rd5

draw agreed

A very good game from my opponent, who I outranked by 200 rating points.

Jerome Gambit: A Complicated Affair (Part 2)

 [continued from previous post]


perrypawnpusher - PasayDefence

"Piano Piano" tournament, Chess.com, 2020

18...Ng4 19.h3 Nf6 20.Kg2 Rd7 

Black can double his Rooks on either central file. He also avoids the possible pin of his Knight, if White plays Bg3-h4.

21.d4 Bb6 22.e5 Nd5 23.f5 


The "Jerome pawns" awaken.

23...Kg8 24.Rde1 

Wrong Rook. 24.Rfe1 would leave the d-pawn protected. 

24...Bc7 

This move puts more pressure on the center, but after the game the computer preferred 24...Rf7, as after  25.c4 Ne7 26.Re4 (protecting the d-pawn) the f-pawn falls to 26...Nxf5.

25.c4 Nb4 


His Bishop's retreat had made room at b6, and that is probably where the Knight should have gone.

26.e6 Rde7 27.Bh4 Nd3 


28.Bxe7

Miscalculating, and missing my chance. Stockfish 12's post mortem  was a bit tricky, but would have led to an advantage for White: 28.Rd1 g5 29.Bxg5 Rg7 30.h4 Nf4+ 31.Kf3 Nxe6 32.fxe6 Rxe6 when White would have been up 2 pawns.

28...Nxe1+ 29.Rxe1 Rxe7 30.d5 


Probably premature. Stockfish's take is 30.h4 h5 31.Rg1 Re8 32.Kf3 Bd8 33.d5 Be7 34.Rg5 b5 35.b3 Rd8 36.Ke4 Rd6 37.Ke5 Rd8 when White's King is much more actively placed, and the game would be about even. 

30...cxd5 31.cxd5 Bd6 


The "Jerome pawns" have been placed under lock and key.

I was at a loss for a plan to free them.

Jerome Gambit: A Complicated Affair (Part 1)

 


The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is one of my recent games from the "Piano Piano" tournament at Chess.com. It is a complicated affair, and I have included links to earlier games to provide some perspective.

My opponent played well. It was unclear to me at the end if my connected passed pawns were signs of hope or merely targets, and so I pursued the draw.


perrypawnpusher - PasayDefence

"Piano Piano" tournament, Chess.com, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Kf8 

Jerome's defense to the Jerome Gambit. Much of its history was recently presented in the post "Jerome Gambit: A Trip Down Memory Lane".

6.Nxc6 

This is the best continuation. I once delayed it a move: 6.O-O d6 7.Nxc6 bxc6 etc. perrypawnpusher - hdig, blitz, FICS, 2007 (1-0, 17)

6...dxc6 

This is the principled capture, as it prevents d2-d4 by White. Otherwise: perrypawnpusher - badhorsey, blitz, FICS, 2011, (1-0, 26)

7.O-O

I have also played 7.d3, which usually was followed by castling

perrypawnpusher - fortytwooz, blitz, FICS, 2010 (1-0, 29); perrypawnpusher - Jore, blitz, FICS, 2011 (0-1, 16); perrypawnpusher - Conspicuous, blitz, FICS, 2011 (1-0, 13); perrypawnpusher -Lark, blitz, FICS, 2011 (1-0, 12); and perrypawnpusher - pitrisko, blitz, FICS, 2011, (0-1, 30) 

I tried 7.Nc3  in perrypawnpusher - Ykcir, blitz, FICS, 2009(1/2 - 1/2, 11). 

7...Be6 

Solid, already placing the Bishop in position to blockade White's e-pawn, if need be.

I have also seen 7...Ne7, in perrypawnpusher - smarlny, blitz, FICS, 2011,(1-0, 25), and the aggressive 7...Qh4 in perrypawnpusher - pitrisko, blitz, FICS, 2011 (0-1, 30) and perrypawnpusher - Al-der,"Italian Game Classic", Chess.com, 2019 (1-0, 26) 

8.d3 

After the game Stockfish 12 recommended the novelty 8.Qe2, which I hadn't even considered, i.e. 8...Nf6 9.c3 Kg8 10.d4 Bb6 11.Re1 Qe7 12.Nd2 h6 13.Nf3 to reduce Black's advantage.

I had played 8.Qf3+ in a long and difficult battle that I eventually lost, perrypawnpusher - CorH, blitz, FICS, 2009 (0-1, 74), 

8...Qh4 


Aggressively played.

I decided to move my Knight over to help protect the Kingside.

9.Nd2 Nf6 10.Nf3 Qh5 11.Bf4 Bg4 


Black's extra piece and better development counts more than a pawn that I might grab.

12.Bxc7 Rc8 13.Bg3

Given Black's upcoming plan to capture on f3, the Bishop might remain more relevant after 13.Bf4

13...Bxf3 14.Qxf3 Qxf3 15.gxf3 Kf7 

16.f4 

Reducing my Bishop to the status of a large pawn. My plan should have been to play f4-f5 as soon as possible, followed by f2-f4 - of course, that second move would have to come after I had been able to enforce d3-d4, or moved my King to unpin the f-pawn.

16...Rhe8 17.c3 Rcd8 18.Rad1 


I was not surprised, after the game, to see that Stockfish 12 rated Black - with the extra piece and powerful development - about 2 pawns better. There was still a lot of work to do.
