Jerome Gambit: More Pie, Please

The following game tells an often-shared tale: it is not enough to know the move that "refutes" a line, it is necessary to know the follow up. This is especially the case in a very sharp, double-edged opening like the Jerome Gambit.

Wall, Bill - PassCapture
lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4



Elsewhere I have referred to this a "pie-in-the-face" variation, and it is one that can come as a shock to the unprepared Jerome Gambiteer - but Bill Wall is hardly unprepared. He has had success against other lines in the 6.d4 variation, and is ready if someone wants to mix it up with the text.

7.O-O Ng4 8.h3 N8f6 

With this move (a novelty according to The Database) Black continues to pursue development over material, refusing to retreat.


Bill has faced other lines as well:

8...Bd6 9.e5 Bxe5 (9...Nxe5 10.dxe5 Bxe5 11.Qd5+ Kf6 12.Re1 d6 13.Rxe5 dxe5 14.Qd8+ Ne7 15.Qxh8 Qe4 [15...Kf7 16.Nd2 Ng6 17.Nf3 Qxf2+ 18.Kxf2 Nxh8 19.Nxe5+ Kf6 20.Nf3 Bf5 21.Be3 Ng6 22.g4 Be4 23.Bd4+ Ke6 24.Re1 Rf8 25.Rxe4+ Kd5 26.Ke3 c5 27.Bxg7 Rf7 28.c4+ Kd6 29.Be5+ Nxe5 30.Nxe5 Rf1 31.Nd3 Rh1 32.Nf4 Rh2 33.Re6+ Kc7 34.Re7+ Kb6 35.Rxh7 Rxb2 36.g5 Rxa2 37.g6 Black resigned, Wall,B - NN, lichess.org, 2016] 16.Qf8+ Ke6 17.Bg5 Qb4 18.Qxg7 Bd7 19.Qf6+ Kd5 20.Nc3+ Kc4 21.b3+ Kxc3 22.Qxe5+ Qd4 23.Bd2+ Kxd2 24.Qxd4+ Kxc2 25.Rd1 Black resigned, Wall,B - Anonymous, lichess.org, 2016) 10.dxe5 Nxe5 11.Qd5+ Kf6 12.f4 Ng6 13.Nc3 d6 14.Be3 Ke7 15.Rae1 Kd8 16.Nb5 Nf6 17.Qc4 Ne8 18.Bf2 Qf6 19.Bd4 Qh4 20.Rxe8+ Kxe8 21.Nxc7+ Kf8 22.f5 Ne5 23.f6 gxf6 24.Qd5 Kg7 25.Qxd6 Rg8 26.Rxf6 Qxf6 27.Bxe5 and won Sorensen,S - X, Denmark, 1888 

8...d6 9.dxc5 N4f6 10.cxd6 cxd6 11.Nd2 Nxe4 12.Nf3 Qh5 13.Ng5+ Qxg5 14.Bxg5 Nxg5 15.Qh5+ Kf6 16.f4 Ne4 17.Qe8 d5 18.Qe5+ Kf7 19.Qxd5+ Black resigned, Wall,B - NN, lichess.org, 2016. 


9.dxc5 Nxe4


I would have expected the consistent 9...h5!? with attack still on Black's mind, although Stockfish 8 prefers 9...Ne5 10.f4 Nc6 and White's advantage is slight.

Black's counter-attack evaporates.

10.Qd5+ Kf6 11.Qxe4 

Having surrendered a piece, Black realizes to his dismay that his Knight is pinned to his Queen - and lost.

11...d5 12.cxd6 cxd6 13.f3 h5 14.fxg4+ Black resigned



Black is down a piece - and faces checkmate.

Jerome Gambit: Past is Prologue

Here is a game from the first round of the Jerome Gambit tournament at RedHotPawn.com. Both White and Black clearly have a grasp of the opening, and the battle is an entertaining one. The outcome is an indication of how the second round - and the tournament - will turn out.

10.hxg4 Nh6

Reasonable and straight-forward, especially since White's response "forces" Black to make a move he wants to make, anyhow; but 10...d6 was deeper and better. 

11.g5 Ng4  

Of course. Still, taking the g-pawn was better, as now the game has equalized - although that may not be apparent at first glance. 

12.Qf3+ Ke8 13.Qh3 Bxg5 14.Bxg5 Qxg5 15.Nc3 d5



15...h5!? was a thematic alternative. 

16.f4 Qg6

Thinking "attack" when "defense" was better attended to by 16...Qd8. 

17.Nxd5 Kd7 18.f5 Qg5 19.e6+ Kc6 



The alternative 19...Ke8 20.Rae1 is pretty bad for Black, but everything else leads to mate. 

20.Qc3+ Kxd5 21.Qc5+ Ke4 22.Rae1+ Ne3 23.Qe5 checkmate

ГАМБИТ ЖЕРОМА


I just reviewed a nice Russian language Jerome Gambit article with a balanced, not mocking, assessment of the opening (and a kind link to this blog, as well). It has several games that can be played over on the site, including ones by historical figures Alonzo Wheeler Jerome, Andres Clemente Vazquez, Henry Charlick and S.A. Sorensen; as well as modern regular visitors to this blog, Bill Wall and Philidor 1792.

Of interest, the site mentions analysis by A. Zherom, a reference I am not familiar with. (For Jerome Gambit analysis from Opening Traps by GM Ferzbery [Boris Vainstein] see this earlier blog post.)

Mr. Fletcher's Gambits


I recently stopped by the website of the Bedford Chess Club, where I noted an interesting entry concerning "Mr. Fletcher's gambits", referring to  L. Elliot Fletcher's delightful book, Gambits Accepted, A Survey of Opening Sacrifices (1954).

The Bedford CC site has examples of 84 gambits that Fletcher covered, as well as 11 gambits that he had missed.

Interestingly enough, the site does not give the Jerome Gambit game that Fletcher provided, but includes the significant Sorensen - X, Denmark, 1888 (1-0, 27).
Fletcher quotes a club game for the Jerome; and none of the surviving games by Jerome himself were won by White. But apparently the Danish player and problemist Soren Sorensen showed an interest in the gambit. 
It is relevant to point out to Readers Sorensen's early article on the Jerome Gambit that was translated into a number of languages and was very influential in popularizing the opening.

I quickly emailed the Club secretary 
Dear Mr. Gill, 
I was delighted to come across your post on "Mr. Fletcher's gambits". A pleasant book I recall fondly, and hope your Club members appreciate as well. 
My own interest in gambits focuses on the Jerome Gambit, which I have researched for 15 years and maintain a blog about (jeromegambit.blogspot.com). I was impressed that you substituted the Sorensen game for Mr. Fletcher's anonymous club game. 
As a small, niggling point, I wanted to mention that I have 7 Jerome Gambit wins by Alonzo Wheeler Jerome in my database (which also includes 9 losses, 2 draws and 6 incomplete games). They are out there, they just required some digging. 
By inference I conclude that you did not accept Eric Schiller's erronious contention in his "Unorthodox Chess Openings" (1998) that the famous Blackburne win (London, 1880) was against Jerome himself; just so. 
Best wishes, 
Rick Kennedy
I soon learned that I had contacted the wrong person. Still, it was great to hear back from Bedford 
Good evening. 
I have to own up to being the perpetrator of the games collection on the Bedford club site based on Elliott Fletcher's book. Given that since I discovered the book in my 'teens (half a century ago) I have had a predilection for dodgy gambits, I guess I should share your view of Fletcher's book as "delightful". Revisiting the book I did find his uncritical attitude to a lot of complete trash a bit annoying and at times his analysis is seriously ropey (the irritation only vents itself openly, I think, in the last note to game 21). 
I think I probably found the Sorensen game courtesy of your blog and apologise for the fact that I didn't look hard enough to find the White wins by Jerome. I am asking the webmaster to amend the noted to Sorensen-NN on the website accordingly. 
I didn't know that friend Schiller was claiming that Blackburne's victim was Jerome himself. Had it been, I think Blackburne might have mentioned the fact in his own collection of his best games; and the fact that Tim Harding finds no evidence for it is pretty strong negative evidence as far as I am concerned. I accept that Schiller is a far stronger player than I will ever be, but (like you, I think) I don't rate him as an author. 
Regards,
Neil Hickman

It was easy to finish up with
Dear Mr. Hickman, 
I had a pleasant, good-natured chuckle at your comment that you found Fletcher's "uncritical attitude to a lot of complete trash a bit annoying" and that "at times his analysis is seriously ropey". Well put - and I agree. Nobody is likely to mistake "Gambits Accepted" for, say, Tartakower and Du Mont's "500 Master Games of Chess". Gary Kasparov's comment that "chess is not skittles" holds true for his portion of the chess world... 
Still, I am delighted at an actual, published  look (before the internet!) at amateur games by an amateur player. "Gambits Accepted" reminds me a bit of Rainer Schlenker's "Randspringer" - with weaker analysis, of course. 
I want to apologize for my snarky comment relating to Alonzo Wheeler Jerome's wins with his gambit. Finding them is not so easy, unless you're a bit of a fanatic (with too much time on his hands) like myself. 
I agree, if AWJ had crossed the pond to have his head handed to him by Blackburne in London in that famous Jerome Gambit game, Dr. Harding would have uncovered some trace of it. Certainly, over here, I have found no trace that the gambiteer ever even left the US. 
Thank you for your time. 
Best wishes,Rick

Brighter Lights


Speaking of "brighter lights" in the world of the Jerome Gambit (see previous post), here is Bill Wall's latest game. The ending should be rated "PG" for either "Parental Guidance advised" or simply "Plain Gory". The King hunt is brutal

Wall, Bill - Anonymous
lichess.org, 2016
(analysis by Bill Wall)

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 




7.O-O Ng4

One of a number of moves that keeps Black's advantage.

8.h3 Bd6

Aggressive, but 8...Bb6 was probably better. It was the choice of several computers ( Deep Shredder 10, Deep Sjeng 1.5,  Hiarcs 11.1, Shredder Paderborn) in computer vs computer tournaments in 2002, 2003 and 2008, for example. It also appeared in Sir Osis of the Liver - perrypawnpusher, JG3 thematic, Chessworld.net, 2008 (0-1, 38) and Wall,B - Rajiv, Chess.com, 2010 (1-0, 33).

9.e5 Nxe5

Giving the piece back is "scientific" but it leads to an equal game, according to Stockfish 7.

With 9...Bxe5 Black returned a Bishop, instead, in Sorensen,S - X, Denmark, 1888 (1-0, 27).

Another piece return was the wild 9...Nxf2 in Darthballz - Leftang, FICS, 2011(1-0, 25).

Bill points out 9...Be7 10.hxg4 d6

10.dxe5 Bxe5 11.Qd5+ Kf6 12.Re1 d6



Bill points out the tricky 12...Bd4 13.Nc3 Bxf2+ 14.Kh1 Bxe1 15.Bg5+, when Black will lose his Queen to either White's Bishop or Knight (when it comes to e4 with check).

13.Rxe5 dxe5 14.Qd8+ Ne7 15.Qxh8 Qe4






Abandoning his King to chaos.

Instead, Black had the prudent 15...Kf7, both protecting his pawn at g7 and the square at f8. If he wanted an exciting draw, he could try 15...Bxh3!? 16.Qxa8 Bxg2 17.Kxg2 Qg4+ and  he could repeat the position with Queen checks.

16.Qf8+ Ke6

The bad news begins. The alternative: 16...Kg6 17.Qe8+ Kf6 (17...Kf5 18.Qf7#) 18.Nc3 Qxc2 19.Qf8+ Kg6 20.Qxe7.

17.Bg5 Qb4

Several other options, from Bill: 17...Ng6 18.Qg8+ Kd6 19.Qd8+ Kc6 20.Nc3 Qxc2 21.Qd5+ Kb6 22.Qb5# ; or 17...Qxc2 18.Qxe7+ Kf5 19.Qxg7; or 17...Nc6 18.Nc3 Qxc2 19.Qg8+ Kf5 20.Qxg7 Qxb2 21.Qf6# 

18.Qxg7

Instead, 18.Nc3 Qxb2 leads to checkmate. 

18...Bd7

The White b-pawn is still poisonous, and 18...Qxb2 would again lead to checkmate.

Best is probably 18...Nf5, but it still leads to misery, e.g. 19.Qg8+ Kd7 20.Nc3 Nd6 21.Rd1 Qd4 22.Rxd4 exd4 23.Qxh7+ Kc6 24.Ne2 Nf5 25.Bd8 as Bill notes. 

19.Qf6+ Kd5 20.Nc3+ Kc4 

Or 20...Kd4 21.Be3+ Kc4 22.Qf7+ Be6 23.Qxe6+ Nd5 24.Qxd5#; or 20...Kc5 21.Qxe7+ Kc4 22.b3+ Kxc3 23.Qxe5+ Qd4 24.Bd2+ Kxd2 25.Qxd4+ Kxc2 26.Rd1 Rd8 27.Qd2#. Black's King is not coming back from this journey.

21.b3+ Kxc3 

Or 21...Kd4 22.Rd1+ Kc5 23.Be3+ Qd4 24.Rxd4 exd4 25.Qxd4+ Kc6 26.Qc5#; or 21...Kc5 22.Qxe7+ Kb6 23.Qxb4+ Ka6 24.Qa3+ Kb6 25.Be3+ c5 26.Nd5+ Kc6 27.Qxc5#. 

22.Qxe5+ Qd4 

If 22...Kxc2 then 23.Rc1+ Kd3 24.Qe3# 

23.Bd2+ Kxd2 

Or 23...Kb2 24.Qxd4+ Kxc2 25.Rc1# ; or 23...Kxc2 24.Qxd4 Rd8 25.Rc1# 

24.Qxd4+ Kxc2 

If 24...Ke2 25.Qe3#

25.Rd1

Threatening 26.Qd2 mate

Black Resigned

"Reality" vs "the Book"


Working on the previous blog post, I noticed that the defender (counter-attacker) had played that variation a few years earlier. The game was interesting enough to share, especially since the defender seemed conversant in Jerome Gambit strategies.. Again, however, "reality" outplayed "the book".

iconsisonline - atizzle
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



7.O-O

This is stronger than 7.dxc5 of Sutarsa - atizzle, blitz, FICS, 2014 (1-0, 19).

7...Ng4 8.h3 Bd6 9.e5 Bxe5


Following Sorensen - NN, Denmark, 1888, pragmatically returning the extra piece for a pawn (or two). Alternatives:

9...Nxf2 10.Rxf2+ Nf6 11.Rf4 Qg3 12.Rf3 Qg6 13.exd6 cxd6 14.c3 b6 15.Qb3+ Ke7 16.Re3+ Kd8 17.Na3 Bb7 18.Re2 Nh5 19.Nb5 Ng3 20.Rf2 Ne4 21.Re2 Rf8 22.Be3 Ng3 23.Rd2 Qe4 24.Re1 Rf3 25.Bg5+ Black resigned, Darthballz - Leftang, blitz, FICS, 2011; and

9...Nxe5 10.dxe5 Bxe5 11.f4 (11.Qd5+ Kf8 12.Qxe5 d6 13.Bg5 Qxf2+ 14.Rxf2+ Black resigned, ndrwgn - balahap, standard, FICS, 2013) Bd6 12.Qd5+ Kf8 13.Nd2 Nf6 14.Qd3 b6 15.Ne4 Bb7 16.Nxd6 cxd6 17.Qxd6+ Kf7 18.Qd3 Rhe8 19.Bd2 Kg8 20.f5 Nh5 21.Bc3 Nf4 22.Qc4+ Kh8 23.Rxf4 Qh6 24.Rg4 Rg8 25.f6 g6 26.f7+ Rg7 27.Qb4 d5 28.f8Q+ Rxf8 29.Qxf8 checkmate, Darthnik - aufdermaur, blitz, FICS, 2011

Black's best defense seems to be 9... Be7 10.hxg4 d6

10.dxe5 N4h6

Sorensen's opponent tried 10...Nxe5, which is playable, if risky, after 11.Qd5+ Kf6. 

11.Nc3 Ne7 12.Re1 Rf8 



Again, Black shows his understanding of the "big issues" in the defense, as he prepares to castle-by-hand.

Unfortunately, the move allows his Queen to be trapped.

White follows up quickly.

13.Re4 Qxe4 14.Nxe4 Kg8 15.Bxh6 gxh6 16.Nf6+ Kh8 17.Qd3 Ng6 18.Qc3 c6 19.Nh5 Rf5 20.e6+ Ne5 21.e7 Black resigned

Keep Fighting


When you are new to playing the Jerome Gambit, you are bound to miss some of its "subtleties", as, most likely, will your opponent. The best advice, as with all gambits, is to "Keep fighting".

The player of the white pieces in the following game has only one Jerome in The Database. Yet his play could be a lesson to veterans of the opening.


Sutarsa - atizzle

blitz, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 


This move, as opposed to 6.Qh5+, was Alonzo Wheeler Jerome's preference when he started playing the opening.


The Database has 1,346 games with 6.d4; White scores 51%. By comparison, it has 3,520 games with 6.Qh5+; White scores 55%.


6...Qh4 


Black's move, a bold counter-gambit seen as early as 1888 in Sorensen - NN, Denmark, is what makes White's 6th move risky - although you will have to take my word for it.


The move shows up only 214 times in The Database (16% of the 6.d4 games) and White scores a misleading 68%.


On the other hand, in a blitz or club game, you might like your odds as White.


7.dxc5


This is a dangerous position for White. Best is 7.O-O


7...Qxe4+ 8.Be3 Nf6


Black's move is solid and good, but the consistent 8...Qxg2 is better. 


9.O-O Neg4 10.Nc3 Nxe3 11.fxe3 Qxe3+ 12.Kh1 Rf8 




Black has only one other game in The Database himself, from four years earlier, but he understands the necessity of safeguarding his King - here, by castling-by-hand.


White has to act fast. While behind in material, he can at least take small encouragement in his opponent's undeveloped Queenside.


13.Qd5+ Qe6 14.Qg5 Kg8 15.Rae1 Qc6




This simple "get out of the way of the Rook" move is the cause of Black's upcoming troubles. Instead, 15...h6 16.Qg6 Qf7 would help him consolidate.


16.Re7 Rf7


The alternative isn't much better: 16...Ne8 17.Rxf8+ Kxf8 18.Nd5 Qxc5 19.Rxe8+ Kxe8 20.Nf6+ gxf6 21.Qxc5.


17.Nd5 Qxd5


Black slides toward checkmate instead of surrendering his Queen. Instead, he could have tried 17...h6 18.Nxf6+ Qxf6 19.Rxf6 Rxe7 (19...hxg5 20.Re8+ Kh7 21.Rxf7) 20.Qd5+ Re6 21.Rxe6 dxe6 22.Qd8+ Kh7 23.Qxc7 or 17...Kf8 18.Rxf7+ Kxf7 19.Qh5+ Kf8 20.Nxf6 gxf6 21.Re1 Qe6 22.Rxe6 dxe6 with dreary prospects. Both lines are worth playing over to see the attack unfold.


18.Qxd5 Nxd5 19.Re8+ Black resigned.

It Happens...


Concerning the following game, I have already written...

If 
you play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ) long enough, you will eventually play the 6.d4 variation (4...Kxf7 5.Nxe5+ Nxe5 6.d4) and one day you will come face-to-face with the best in-your-face variation for Black since J.H. Blackburne offered his Rook...

Sometimes, when you play the Jerome Gambit, you encounter an opponent who knows one of the refutations and who plays very well against you. It happens.


Wall,B - Guest6296711
PlayChess.com, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 




This line doesn't have a name attached to it, but I have referred to it in earlier posts as "A Pie-in-the-Face Variation". The earliest example that I have of it in The Database is Sorensen - Anonymous, Denmark, 1888 (1-0, 27).


It is interesting to note that The Database has 1213 games reaching the position after 6.d4, with White scoring 50%. Of those games, only 17% of the time does Black continue with 6...Qh4 - but he scores 70% with it.


7.0-0 Qxe4 


The weaker alternative, 7...Ng4, was seen in Sorensen,S - X, Denmark, 1888 (1-0, 27), Sir Osis of the Liver - perrypawnpusher, JG3 thematic, ChessWorld.net, 2008 (0-1, 38) and Wall,B - Rajiv, Chess.com, 2010 (1-0, 33). 


8.dxc5 Nf6 9.Nc3 Qc4 


Instead, Black played 9...Qc6 in Wall,B - Gorodetsky,D, Chess.com, 2010 (1-0, 18) and Wall,B - felineMMXI, blitz, FICS, 2011 (1-0, 18). 


10.Be3 


This is a small improvement over 10.Re1 Qxc5 11.Be3 Qc6 in Deep Sjeng 1.5 - Junior 7, The Jeroen Experience, 2003 (0-1, 46).


Black's extra piece outweighs White's two extra pawns. 


10...Re8 11.Bd4 d6 12.b3 Qa6 13.cxd6 Qxd6 14.Nb5 Qc6 15.Nxa7 Rxa7 16.Bxa7 b6 




17.Qd4 Ba6 18.c4 Nf3+ 




Black finishes off with sacrificial flair.


19.gxf3 Qxf3 20.Qd1 Re2 21.Qd8 Qg4+ 22.Kh1 Bb7+ White Resigned
