Jerome Gambit: First There Is The Confusion Factor

I am reading IM Sam Collins' Gambit Busters* (Everyman Chess, 2010) with a know-your-enemy focus, and enjoyed the following, from the chapter "Escaping the Defensive Mindset"
It is well known that club players, typically, go to pieces when confronted by a gambit. Of course, for every player there are some gambit lines which they know, and perhaps their theoretical knowledge will suffice to get them to a safe position. But this won't be the case when they are confronted by an established gambit they don't know, an unusual or forgotten gambit, or where their opponent deviates from theory. 
To my mind, gambits are the situations where there is the single biggest gap between passively looking at a position at home, and facing something over the board. Skimming over an opening variation with a cup of tea, maybe Rybka muttering in the background, it all looks so straightforward - an "=" symbol (or something even more favourable), a bunch of crisp responses demonstrating the intellectual failure of our opponent's adventure. 
But at the board, things are rather different. First, there is the confusion factor...

Yes, indeed. At the level of play that the Jerome Gambit is exhibited, it is often "unusual" or "forgotten" enough to lead to success. Certainly it can lead to "confusion".

"Knowing" that the opening is refuted, looked askance at by "the book" and hooted at by computers, it must be infuriating (or embarassing) for the defender to be struggling against such a monstrosity.

I am remined of the story about chess great Aaron Nimzovich climbing on a table and bemoaning "Why must I lose to this idiot?" More recently, Bill Wall shared the scolding he received from his opponent after having the audacity to play - and win with - the Jerome Gambit. The opening is garbage, it would never work against a grandmaster, the world champion would never play such a thing...

Ah, yes. In my pre-Jerome Gambit days I would repeatedly defeat a friend who always protested "But I was winning!" I would reassure him that, yes, he was winning, right up to the point where I checkmated him.


(*I am enjoying Collins' work, and I appreciate the classic games that he chooses to illustrate his points. I was surprised, however, in the mentioned chapter, that after all that he wrote of the tribulations of "club players" he chose a game between super-Grandmasters Anand and Shirov to drive the point home.)

Appearance and Reality

Image result for free clip art magic

In the following game, Black leaps upon what he considers an error by White, only to find that he has attacked thin air, while, on the other side of the board, he allows a deadly attack!


Wall,B - Guest1468045 
PlayChess.com, 02.04.2015

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qc3


A similar position including the "nudge", after 7.Qd5+ Kf8 8.Qxc5+ d6 9.Qc3 was seen in Wall,B - Boris, SparkChess.com, 2012 (1-0, 32),  Wall,B -Guest4149739, PlayChess.com, 2013 (1-0, 30) and Wall,B - Guest428245, PlayChess.com, 2014 (1-0, 20). 



The alternative, 8.Qd5+, looking for mischief, was seen in Wall,B-Guest4395, Microsoft Internet Gaming Zone, 2001 (1-0, 18);  Wall,B - Seven11, Chess.com, 2008 (1-0, 51); Wall,B - Chung,J, Chess.com, 2010 (1-0, 25);  Wall, Bill - CheckMe, www.Chess.com, 2010 (1-0, 23); and Wall, Bill - Guest249301, playchess.com, 2013 (1-0, 30).

8...Nf6 9.d3 Re8 


10.0-0 h6 11.f4 Kg8 12.Nd2 c6 



Houdini rates Black about a half point better here; while Stockfish sees Black as maybe nine-tenths of a pawn better. That's plenty for White to work with.


13.b4!? 


Bill and I have exchanged emails about this move. I like it - a lot. It reminds me both of the comment attributed to Bobby Fischer - "I don't believe in psychology, I believe in strong moves" - and one by Nimzovich - that a particular move was strong, because it appeared weak...


Notice how Black jumps all over the move. Notice how Black loses.


13...Qb6+ 14.Kh1 Ng4 15.Bb2 Re7 




As Bill points out, Black pauses for some defense: not 15...Nf2+? 16.Rxf2 Qxf2?? 17.Qxg7#


16.d4


Likewise, avoiding 16.Qc4+? Be6 17.Qd4 Ne3.


16...a5 


Here we go again: attacking the White b-pawn.


17.Qg3 


Which White abandons!


17...Qxb4


Black has the pawn in the bag, and forks two of White's pieces. What's not to like?


18.Bc3


Bill was aware of 18.f5? Qxb2 19.Qxg4 Qxd4 20.Qxg6 Qxd2.


18...Qb5 19.f5 


We will come back to this position.


19...Bxf5 


This looks like the beginning of panic. Black's Knights are at risk.


20.Rxf5 N4e5 21.dxe5 Nxe5 22.Raf1 Rae8




Collapse.


23.Bxe5 dxe5 24.Qg6 Qe2 25.Rf7 Rxf7 26.Rxf7 Qe1+ 27.Nf1 Re7 28.Qxg7 checkmate


Going back to the diagram after White's 19th move let's ask: What would have happened if Black had admitted that his "advantage" had evaporated, that his "right to attack" had therefore disappeared, and he had retreated with 19...Nf6?


As I had emailed Bill

Funny how 19...Nf6, admitting Black's mistake, would have mostly set things to rights.. : 20.Qxg6 Qxb4 21.e5 Nd5 22.Nb3 a4 23.f5! Bxf5 24.Rxf5 axb3 25.c3! Nxc3 26.exd6 Re2 27.d7! Nd5 28.Raf1 Re1! 29.axb3 Ne3 30.Bc3! Qxc3 31.Rf7 Rxf1+ 32.Rxf1 Nxf1 (what else?) 33.Qe8+ Rxe8 34.dxe8/Q+ Kh7 35.Qe4+ and it was a draw, after all... But even in this line White has almost all of the fun!

Restrain, Blockade, Destroy


The watchwords of Aaron Nimzowitsch (1886-1935) "restrain, blockade, destroy" come to mind in playing over the following game, as Black seems to utilize "hypermodern" concepts in has battle against a clearly "neo-romantic" chess opening.

It is one of the stranger Jerome Gambits I have ever seen.


Wall, Bill - Guest4149739

PlayChess.com, 2013

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8


More common is 7...Ke8.


8.Qxc5+ d6


There is also 8...Qe7, as in Wall,B - Quack, Chess.com, 2010 (1-0, 22)


9.Qc3


The more-often played 9.Qe3 is as old as Vazquez,A -Carrington,W, Mexico, 2nd match, 1876 (1-0, 34) and as new as Wall,B - Vijay,V, Chess.com 2010 (1-0, 22) and Wall,B - LC, Chess.com, 2010 (1-0, 20)



9...Nf6 10.d3 Qe7


A slight improvement over 10...c6 as in Wall,B - Boris, Sparkchess.com, 2012 (1-0, 32). So far, we have a normal Jerome Gambit-style position.


11.O-O c6 12.f4 Bd7 13.f5 Ne5 14.h3 


Bill later suggested 14.Bf4.


14...c5 15.g4 Bc6 


White has activated his "Jerome pawns" and in response Black has started to restrain them and - with his Knights - blockade them.


An indication of how further "odd" the position can get is in Houdini's recommendation, instead of Black's last move: 15...g5 16.Bxg5 h5 17.h4 hxg4 18.a4 Be8 19.Nd2 Bf7


16.g5 Nfd7 17.b4 h6 18.g6 Qh4 




Black has about had it with all of White's pawn moves (Bill has also created this impatience in his opponents with repeated Queen moves) and decides to become aggressive, here threatening 19...Qg3+


19.Kh2 b6 20.a4


Instead, 20.Bf4 was a possibility. 


20...Nf6 21.Bf4 


Bill shows how things could go horribly wrong for White: 21.bxc5? Nd5 22.exd5 Ng4+ 23.Kg2 Bxd5+ 24. Kg1 Qg3 checkmate


21...Re8 


22.Nd2 Nh5 23.Bxe5 Rxe5


Threatening 24.. .Qg3+.


24.Rf3 


White's King is still at risk: 24.bxc5? Qg3+ 25.Kh1 Rxe4 26.dxe4 (26.Nxe4 Bxe4+ 27.dxe4 Qxc3) 26...Qxc3. 


24...Ke7 25.Rg1


White completes his development (!) and sets an interesting trap for his opponent.


25...Bxa4


This can lead to a slight advantage for White (better was 25...Kd7), or a whole lot more.


26.Ra1 b5 


Black protects his Bishop and blocks the a-file against the White Rook. Instead, he should have retreated his piece with 26...Bd7 and let the White Rook in, facing a small disadvantage. However, this was far from obvious.


27.d4 


With this move White takes over the game.


27...cxd4 28.Qc7+ Kf6


This leads to checkmate, whereas 28...Ke8 only leads to disaster after 29.Qc6+ 


29.Qxd6+ 


A bit faster was 29.Rg1


29...Kg5 30.Rg1+  Black resigned




It is ironic that Black, ahead in development for most of the game, should have his King expire with a Bishop offside and a Rook lollygagging at home.

It's A Small World After All (Part 1)


I would like to share another typical Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) story. "Typical" in that, of course, it has several rather odd features...

A Reader from the Netherlands requested a copy of The Database the other day.

Like my book, The Marshall Gambit in the French and Sicilian Defenses, which was more popular in Europe than in the USA, this blog has a decent international following. (There is nothing quite like watching a player from Moldova, in the current ChessWorld Jerome Gambit Thematic Tournament, successfully play a move that I have championed, and others mostly have ignored.)

I was happy to oblige.

I was even happier when the Reader offered, in return, his Jerome Gambit (and related openings) collection. Although The Database has over 25,500 games, it is focused largely on FICS games and those that I have discovered in my historical research. I know that there are many, many other games out there.

One of my new aquisitions was the 1964 "offhand game" between "Marfia, J" and "Stelter, J".

I wondered: was that Jim Marfia, author of four books on the U.S. Open in the 1980s; author of Queen's Gambit with Bf4 and Queen's Indian with 4.g3; and translator for Botvinnik's 15 Games and Their Stories and Botvinnik on the Endgame, as well as Korchnoi's Persona Non Grata, Nimzovich's Carlsbad International Chess Tournament 1929, and Bronstein's Zurich International Chess Tournament 1953 (among others)?

After some searching, I discovered that "the" Jim Marfia was involved in West Michigan Chess. Further searching oncovered a recent game and the fact that he was playing games online at queenalice.com and GameKnot.com under the handle "fluffybunnyfeet".

As my wife said, "You can't make this stuff up..."

A Working Class, Impatient Move

Bobby Fischer played successfully with and against the Sicilian Najdorf variation, referring to 5...a6 as "a high class waiting move."

In contrast, in the Jerome Gambit's (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), Jerome Defense, Black's 7...Bd6 can be considered "a working class, impatient move" – but one that both White and Black should become more familiar with.

perrypawnpusher - LeiCar
blitz FICS, 2010

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8


Alonzo Wheeler Jerome mentioned this move in his 1874 analysis of the Jerome Gambit in the Dubuque Chess Journal. He later successfully played the defense in two correspondence games against Daniel Jaeger in 1880.

7.Qxe5 Bd6


In the updated New Year's Database, White has scored 45% in 243 games with this position.

I like this move. It looks like the kind of "ugly" move that Nimzovich and Tarrasch would have argued about. It's primative, it's raw, it's... hey, what should White do in response??

8.Qf5+

Previously I tried 8.Qc3  as in 8...Nf6 9.d3 Qe7 10.Bg5 h6 11.Bh4 Bc5 12.0-0 d6 13.d4 g5 14.dxc5 gxh4 15.cxd6 Qxd6 16.Nd2 Rg8 17.f4 Bh3 18.Qxh3 Qxd2 19.Rf2 Qd4 20.Qf5 Qxb2 21.Re1 Qb6 22.e5 Rg7 23.exf6 Rf7 24.Re6 Qb1+ 25.Rf1 Qxa2 26.Rfe1 Qb2 27.Qg6 Qd4+ 28.Kh1 Qxf4 29.Re7 Rxe7 30.fxe7, checkmate, perrypawnpusher - Lark, blitz FICS, 2009;

while Bill Wall ground his opponent down with 8.Qa5 Qf6 9.Nc3 Ne7 10.d3 h6 11.0-0 b6 12.Qa4 c6 13.Be3 Bc5 14.e5 Qg6 15.Ne4 d6 16.Nxd6 Bh3 17.Qe4 Qxe4 18.dxe4 Be6 19.Bxc5 bxc5 20.f4 Nc8 21.f5 Bd7 22.Nb7 Ke7 23.Nxc5 Rf8 24.f6+ gxf6 25.exf6+ Rxf6 26.Rxf6 Kxf6 27.Nxd7+ Ke6 28.Nc5+ Ke5 29.Re1 Nd6 30.Nd3+ Kd4 31.e5 Ne4 32.e6 Re8 33.e7 Rxe7 34.Nf2 Re5 35.Nxe4 Rxe4 36.Rxe4+ Kxe4 37.Kf2 Kd4 38.g4 c5 39.Kf3 Ke5 40.h4 a5 41.a4 c4 42.c3 Kf6 43.Ke4 Ke6 44.Kd4 Kf6 45.Kxc4 Ke5 46.b4 axb4 47.cxb4 Kf4 48.b5 Kxg4 49.a5 Kxh4 50.a6 Kg4 51.a7 h5 52.a8Q h4 53.b6, Black resigned, billwall - firewine, Chess.com 2010;

and Pete Banks scored a quick win with 8.Qh5 Nf6 9.Qf3 Kg8 10.d4 Kf7 11.e5 Black resigned, blackburne - Whiterose, ChessWorld, 2004

Deep Rybka, working in IDeA mode in Aquarium, rates a handful of moves about the same, showing a slight preference for 8.Qb5.

8...Qf6 9.Qxf6+ Nxf6


I have been convinced by better players than myself not to fear the Jerome Gambit end game, although I would still like to find a way to keep my Queen on the board.

10.d3

Or 10.Nc3 Be5 11.d3 Bxc3+ 12.bxc3 d6 13.0-0 Kf7 14.f4 Rf8 15.h3 Kg8 16.g4 Bd7 17.Kh2 Rae8 18.Ba3 Ba4 19.Rf2 Nd7 20.Re1 Ne5 21.Ref1 Nf7 22.Kg3 h6 23.h4 c5 24.Re1 b6 25.c4 a6 26.Bb2 b5 27.cxb5 axb5 28.g5 hxg5 29.hxg5 b4 30.Rh1 Nd8 31.f5 Nc6 32.g6 Ne5 33.Bxe5 Rxe5 34.Rfh2 Black resigned, mrjoker - PhlebasP, ICC, 2008.

10...Bc5


Another Jerome Gambit Gemeinde member with 214 games in the New Year's Database (scoring 52% over all) faced, instead, 10...b6 11.0-0 Bb7 12.f4 Bc5+ 13.Kh1 Ke7 14.c3 d5 15.b4 Bd6 16.e5 Bxb4 17.exf6+ Kxf6 18.cxb4 Rhe8 19.Bb2+ Kf7 20.Na3 Re2 21.Be5 Re8 22.d4 c5 23.bxc5 bxc5 24.Nb5 cxd4 25.Nd6+ Kf8 26.Nxe8 Kxe8 27.Bxd4 Ba6 28.Rfe1 Rxe1+ 29.Rxe1+ Kd7 Black resigned, UNPREDICTABLE - dameyune, FICS, 2009.

11.Nc3 Ng4 12.0-0 d6 13.h3 Ne5


Black is working on finding a plan.

14.Bf4 Kf7 15.Nd5 Bb6 16.Nxb6 axb6


17.Be3 Rf8 18.f4 Nc6 19.c3 Kg8 20.d4 Ne7

White is mobilizing his "Jerome Pawns." Black still has the advantage, though.

21.f5 c6 22.Bg5 Rf7 23.Bxe7


A thoughtless move. Instead, 23.g4 was thematic and led to an almost-equal game.

23...Rxe7 24.Rf4 Bd7 25.g4 Rf8 26.Re1


26...g5

Taking a shorter step – 26...g6 – seemed more prudent to me, but Rybka let the text move go by without comment.

27.Rff1 c5 28.e5 dxe5 29.dxe5 Rfe8


The game seems in balance.

30.e6 Bc6

Of course, Black could have returned his piece for the two pawns (30...Bxe6 etc), but LeiCar was looking for more than an equal game.

Unfortunately for him, that was my best offer.

31.f6


As the villains say in many Scooby Doo episodes ...and I would have gotten away with it too, if it weren't for you meddling pawns, er, kids...

31...Rxe6 32.f7+ Kf8


This allows White's pawn to capture, promote and check. The alternative, 32...Kg7, would have allowd Black to capture the passer and would have cost only the exchange, but Black's position would have been poor after 33.Rxe6 Rf8 34.Rf5 Rxf7 35.Rxg5+ Kh8, for example, with 36.Rd6 Re7 37.Rd8+ Be8
