Jerome Gambit: A Day in the Life

I have shared many games where White plays the notorious Jerome Gambit, patiently musters his forces, waits for the defender to make a mistake - and then pounces. After all, I like the Jerome Gambit, and it is fun to watch players use it and succeed.

Yet, I have not been shy about sharing the many refutations of the opening, as well. A line of play can be both exciting and dangerous for the user.

So, as a bit of balance, here is a three minute game that shows Black has chances, too. ☺ (He should: he is rated +200 above White.)

Readers should follow the links to see more alternative ideas for White.

Chess-For-All - Sveti14
3 0 blitz, lichess.org 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5. Nxe5+ Nxe5 6.Qh5+ Kf8 

The Jerome Variation of the Jerome Gambit, played by Alonzo Wheeler Jerome against David Jaeger in correspondence, 1880.


7.Qxe5 d6 8.Qg3 Nf6 9.Nc3


I was surprised to find only 13 games in The Database with this move, with White scoring only 46%. (Still, that is a bit of a step up from the 42% score for White after his 7th move.)

9...Kf7

Also seen: 9...Nh5 in Wall,B - Ahmadi,S, Chess.com, 2010 (0-1, 59) and 9...Ng4 in perrypawnpusher - klixar, blitz, FICS, 2007  (1-0, 33). 

10.O-O Re8


Black has also done well with 10...Rf8 as in perrypawnpusher - truuf, blitz, FICS, 2011 (0-1, 32) and Wall,B - Guest874250, PlayChess.com, 2014 (0-1, 32). 

11.d3 Kg8


Taking care of business by castling-by-hand.

Also seen: 11...Qe7 as in mrjoker - creeredes, Internet Chess Club,
2008 (0-1, 26) 

12.h3 

Adopting the come-and-get-me strategy that puts the onus on Black to make something out of his material advantage. Sometimes this can be a part of a psychological push by White that unsettles his opponent - but, not today. Perhaps he should have ignored the move and gone ahead with winning the "minor exhange" with 12.Na4.

12...Qe7 13.Kh1 

This reminds me of the quote by the Joker in "The Dark Knight" movie: "Come on. I want you to do it. I want you to do it. Hit meHit me! I want you to hit me!"

13...Qf7 14.Be3 Nh5 15.Qh4 Bb6 




16.Nd5 Nf6 17.Nxb6 axb6 18.a3 d5 19.f3 Be6



20.g4 

Time to try to stir things up a bit.

20...Nd7 21.Bd4 

A move that is easy to understand, but repositioning the Bishop might have been better done by playing 21.Rae1 first, and if  21...c5, then  22.Bd2, eventually coming to c3. This subtle idea is brought to you by Stockfish 8.

21...Rf8 


22.f4 

Impatient - but, remember this is a 3 0 game.

The recommended line by Stockfish 8 would have been hard to work out, even in a slower game, with White finally developing pressure on the Kingside to offset Black's gains on the Queenside: 22.Qg3 c5 23.Bc3 d4 24.Be1 c4 25.f4 Nc5 26.f5 Bd7 27.Rd1 Bb5 28.Rf3 Rac8 29.Bb4 cxd3 30.cxd3 Rfe8 31.Rd2 Qb3 32.Kg2 Nd7 33.Rff2 Rc1 34.Kh2 Ne5 35.f6 Qf7 36.Rf5 gxf6 37.g5 Qg7 and Black would still be better. 

22...dxe4 23.dxe4 Bc4 24.Rf2 Rae8 25.Re1 Rxe4 26.Rxe4 Bd5



The a8-h1 diagonal is deadly.

27.Rfe2 Re8 28.Be5 Bxe4+ 29.Rxe4 Qd5 



Again.

30.Qe1 Nc5 White resigned



Ouch.

Jerome Gambit: The Nightmare Before Christmas

Image result

I borrowed part of the title of this blog post from Tim Burton's animated film, but it seemed to be about right in describing the following game.

Those who play the Jerome Gambit need to constantly remind themselves that it is, technically, a refuted opening, and that there are a number of winning defenses that Black can play.

True, there are many circumstances which lead to the defender not making use of his advantages, and White wins - sometimes quite impressively. Learning to take advantage of any slip or error is critical.

However, sometimes there are games like the following. SeinfeldFan91 won the RedHotPawn.com Jerome Gambit tournament by succeeding in all of his games - and that means wins with Black, as well as wins with White.

kristjan - SeinfeldFan91
Jerome Gambit Tournament, RedHotPawn.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4


At first Alonzo Wheeler Jerome favored this move over 6.Qh5+, and it has much going for it - including winning back one of White's two sacrificed pieces.

A quick look at The Database (which is a good measure of club player success, not necessarily "theoretical" or computer success) shows 1,499 games with 6.d4, with White scoring 52%. This can be compared with 3,793 games with 6.Qh5+, with White scoring 55%.

6...Qh4 

This is the strongest theoretical response to 6.d4, and it appears in 230 games in The Database. However, as a measure of how chaotic the game becomes in this double-edged variation - White scores 67%!

This is another indication that familiarity and understanding of the Jerome Gambit is very important: Play what you know, and know what you play.


7.dxc5

Here the Database statistics line up with the recommendations of the computers. The text move appears in 67 games with White scoring 28% - not bad when considering that the line is "lost" for the attacker, but not best. There are 154 Database games with the also "lost" (but better) move 7.0-0, and White scores 87% - it is always good to understand your practical chances in a wild line! 

7...Qxe4+ 8.Kf1 Nf6 9.Nc3 Qb4 



Some alternatives:

9...Qh4 10.Be3 b6 11.Ne2 bxc5 12.Ng3 d6 13.c3 Ba6+ 14.Kg1 Rhe8 15.Qb3+ c4 16.Qd1 g6 17.Kf1 Neg4 18.Bd4 Nxh2+ 19.Kg1 Nfg4 20.Qd2 Bb7 21.Qf4+ Kg8 22.Rxh2 Qxh2+ White resigned, HauntedKnight - blocbloc, FICS, 2016;

9...Qc4+ 10.Kg1 Qxc5 11.Be3 Qe7 12.g3 d6 13.Kg2 Bg4 14.Qd2 Bf3+ 15.Kg1 Bc6 16.f4 Nf3+ White resigned, HauntedKnight - truuf, FICS, 2014; and

9...Qc6 10.Bg5 Re8 11.Bxf6 Qxf6 12.Nd5 Qf5 13.Nxc7 Ng4 14.Qd5+ Qxd5 15.Nxd5 Re5 16.c4 b6 17.cxb6 Ba6 18.b3 axb6 19.Nxb6 d5 20.Nxa8 dxc4 21.Nc7 Rf5 22.Nxa6 Nxf2 23.Kg1 c3 24.Rc1 Ne4 25.Nb4 Rf2 26.Rxc3 Rb2 27.Rf3+ Ke6 28.h3 g5 29.Kh2 h5 30.Re1 Ke5 31.Nd3+ Black resigned, PasChat - plamb, FICS, 2014

10.g3

At this point something like 10.Be3 to focuse on development was probably better. Still, the situation is grim.

10...d5 11.Kg2 Bg4 12.Qe1 Rhe8 White resigned



Playing on a piece down, with the loss of more material imminent, was not appealing.

Hard Work

Image result for free clip art mail

The third of the recently-supplied games by shugart, at FICS, shows White confronting a difficult defense - and prevailing. You need only look in the notes and see others who lost in those lines - fehim, MrJoker, perrypawnpusher, wall - to appreciate the challenge. It is as if his attack sneaks up on his opponent.

Black wants an open line for his Bishop, but this move actually allows White to keep things closed. White needs the time to work on his development.

16.e5 Nd7 17.d4 Qe7 18.f4 Kg8

Overlooking the potential of the "Jerome pawns".

19.f5 Bf7

Usually the out-of-play Rook for Black is the one on a8. This time it is the one on h8.

20.f6

Even stronger is Bh6!?, now or the next move.

20...Qf8

Black underestimates the attack. Stockfish 7 suggests, instead, returning the extra piece: 20...Nxf6 21.exf6 Bxg3 22.fxe7 Bd6 23.a4 Bxe7 24.Nd3 when White would have a small advantage (Knight goes to e5, pawn weakness at c6) despite Black having the two Bishops.

21.fxg7 Qxg7 22.Qh3 h5 23.Qxd7 Kh7 



24.Qxc7

Good enough. (Crushing was 24.Rxf7!?)

24...Rhg8 25.Rxf7 Black resigned

Caution!

It feels somewhat strange to urge caution in a chess opening that is known to be refuted - if the "best" lines still lose, what can be said of the "lesser lines"? Much seems to turn on "psychology", where the "best" move might be the most obscure or unclear or unsettling move - regardless of its "objective" worth - one that gives the opponent the greatest chance to go wrong.

So many times, the opponent takes that chance.

It is worth examining the play of HauntedKnight's games (as we have done before; see "Familiar Territory"), below, for ideas on how to pursue the attack.

HauntedKnight - blocbloc
FICS, 2016

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 



This move was, at first, Alonzo Wheeler Jerome's favorite response, although he later turned to 6.Qh5+.

6...Qh4

This is Black's sharpest response.

7.dxc5 

HauntedKnight has over 400 games in The Database, and he has scored 50%+ in them, so it feels a bit presumptious to suggest that he play the "better" move, 7.0-0, like he did previously:

7.O-O Ng4 8.h3 Bb6 9.hxg4 Nf6 10.g5 Ng4 11.Qf3+ Kg8 12.Qh3 Qxh3 13.gxh3 Bxd4 14.hxg4 d6 15.c3 Bb6 16.Kg2 Bxg4 17.f3 Bh5 18.Nd2 h6 19.Nc4 Bf7 20.Nxb6 axb6 21.gxh6 gxh6 22.Kf2 Kh7 23.Rh1 h5 24.Be3 Rhg8 25.b3 Rg7 26.Ke2 Rg2+ 27.Kd3 Raxa2 28.Rab1 Rh2 29.Rhg1 h4 30.Rg4 h3 31.Rh4+ Kg8 32.Bd4 Kf8 33.Rh8+ Ke7 34.Rh7 c5 35.Bh8 Ke8 36.Bf6 Rhd2+ 37.Ke3 h2 38.Rh1 Rg2 39.b4 cxb4 40.cxb4 Rae2+ 41.Kf4 d5 42.Rh8+ Kd7 43.exd5 Bxd5 44.Rh7+ Kc6 45.Bd4 Rd2 46.Rh6+ Kb5 47.Rxb6+ Kc4 48.Bc5 Rg1 49.Rxh2 Rxh2 50.Rxb7 Rh4+ 51.Ke5 Rh5+ 52.Kd6 Rg6+ 53.Kc7 Rh7+ 54.Kb8 Rxb7+ 55.Kc8 Rg8+ 56.Bf8 Rxf8 checkmate, HauntedKnight - scarlattibach, FICS, 2012.

This is an improvement over two other lines for White:

This is an odd idea, instead of continuing the attack with 18...Bb7. Perhaps Black miscalculated something. This is the kind of opportunity many Jerome Gambit players expect and enjoy.

19.Kg1 Nfg4 20.Qd2 

White should have continued to recover the piece with 20.Nf1 Qg5 21.Nxh2 Nxh2 22.Rxh2

Still available was 21.Nf1

21...Kg8 22.Rxh2

A final oversight.

No Doc


Bill Wall is not a professional psychologist, but when it comes to playing off-beat chess openings, he understands a lot about how his opponents think. This can be of considerable help when playing the Jerome Gambit.

In some of the notes I give a number of complete Wall games that have been referred to in previous blog posts, but have never been presented in their entirety.

Wall, Bill - Guest2928386
PlayChess.com,  2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

Bill has also tried 9.Nc3 Nh5 (or 9...Kf7 as in perrypawnpusher - truuf, blitz, FICS, 2011 [0-1, 32] or 9...Ng4 as in perrypawnpusher - klixar, blitz, FICS, 2007 [1-0, 33]) 10.Qf3+ Qf6 11.d3 Qxf3 12.gxf3 Bd7 13.Ke2 Bd4 14.Be3 Bf6 15.Nd5 Bd8 16.Rhg1 Kf7 17.f4 c6 18.Nc3 g6 19.f3 Be6 20.Rad1 Rf8 21.d4 d5 22.Kd3 Bc7 23.Ne2 Ke7 24.e5 Ba5 25.c3 Bb6 26.a4 Rae8 27.Ra1 Ba5 28.b3 Kd7 29.Rg2 Kc8 30.Kc2 Ng7 31.Kb2 Kb8 32.b4 Bd8 33.a5 Bh3 34.Rg3 Bf5 35.Nc1 Ne6 36.Kb3 Be7 37.Rg1 Bh3 38.Nd3 g5 39.fxg5 Rxf3 40.Rg3 Rxg3 41.hxg3 Rg8 42.a6 Bxg5 43.Rh1 Bf5 44.Bxg5 Bxd3 45.Bh4 Bxa6 46.Kc2 Kc8 47.Rh2 Kd7 48.Rf2 Ke8 49.Rf6 Rg6 50.Rf5 b6 51.Rh5 h6 52.Bf6 Kd7 53.Rh3 Bc4 54.g4 a5 55.bxa5 bxa5 56.Rh2 a4 57.Kb2 Nf4 58.Ka3 Bb3 59.Rh4 Nd3 White resigned, Wall,B - Ahmadi,S, Chess.com, 2010.

10.O-O

Bill takes a wait-and-see stance. Similar, but for comparison: 10.Be3 Bxe3 11.Qxe3 Kf7 12.h3 Be6 13.f4 c5 14.f5 Bd7 15.g4 Re8 16.O-O Bc6 17.Qf4 Qb6 18.b3 Rad8 19.Nd2 c4+ 20.Kh2 cxd3 21.Nc4 Qd4 22.cxd3 Qxd3 23.Rad1 Qc2+ 24.Rd2 Qc3 25.Nxd6+ Rxd6 26.Qxd6 Nxe4 27.Qc7+ Kg8 28.Rd8 Qg3+ 29.Kh1 Nf2 checkmate MrJoker - Macuta, Internet Chess Club, 2011. 

10...Bh5 11.h3 Qe7 12.Nc3 c6 13.a3 



Okay, Bill's got me puzzled - and I know something about the Jerome Gambit. How can he afford to play 11.h3 and 13.a3 when he is playing a gambit, and time is supposed to be of the essence?

As we will see, he accurately accesses his opponent as being unprepared or uncertain about the proper defense (although the light-squared Bishop is free and trying to protect the Kingside), so there is time for White to keep his options open.

Sometimes letting Black keep his options open can lead to him making errors.

13...Bg6 14.Bg5 Qe5 15.Bf4 Qe6 16.Na4 



If nothing else, Bill can eliminate his opponent's "two Bishops". 

16...Nh5 17.Nxc5 dxc5

Not 17...Nxg3 18.Nxe6+ Ke7 19.Bxg3 Kxe6 20.f4. 

18.Bd6+ Ke8 19.Qh2 


19...Kd7

Too casual. It is not clear that the King is safer in his new position, and the (doubled) pawn that he give up is certainly of worth.

20.Bxc5 b6 21.Bd4 Qf7 



Black's pieces are not so much developed as they are jumbled on the Kingside. His Bishop should have gone to f7 on his last move.

22.f4 Qe7 23.g4 Nf6 24.e5 Nd5

Bill points out that Knight retreats lead to trouble too: 24...Ng8 25.f5 Be8 26.f6 gxf6 27.exf6 Qf7 28.Rae1 or 24...Ne8 25.f5 Bf7 26.e6+

25.f5 Be8 26.c4 Nc7 27.b4



Those crazy pawns! All 8 of them.

It is important to mention that Stockfish 6 rates White about 1/2 pawn better in this position. If Black can remain calm, he should be able to hang on.

27...Rf8 28.e6+ Kc8 29.a4 Kb7 



Black has castled-by-hand, but his King still needs to be careful. I've got him right where he wants me! he might have thought, somewhat confusedly.

30.a5 Na6 31.b5 cxb5 
32.cxb5 Bxb5 33.Rfb1 Nc7 



Black's light-squared Bishop continues to defend valiantly with the Knight, but - those pawns...
34.axb6 axb6 35.Qg2+ Kc8

Black's situation has deteriorated to the point that only 35...Kb8 would save him from a forced checkmate.

36. Rxa8+ Nxa8 37.Qxa8+ Kc7 38.Be5+



Black resigned
