Jerome Gambit: An Overlooked Defense

One of the great excitements of playing the disreputable Jerome Gambit is that, beyond the historical "refutations" that are out there - and I have presented as many as I am aware of in this blog, out of a simple sense of honesty and for historical accuracy - you will sometimes have the opportunity to face new or little-played "refutations".

Sometimes they will appear as impediments.

Sometimes they will appear more as mere defenses.

You have to get past them all, anyhow. Like in the following game. 

Wall, Bill - Guest532296
flyordie.com, 2017

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




4...Kxf7 5.Nxe5+ Nxe5 6.d4 d5 



Fascinating. And why not? Isn't the proper counter in a King's pawn game the full advance of the Queen's pawn?

So, why are there only four other games with this move in my 55,650 game Database?

Oh, and condolences to Guest532296, but two of them are by his opponent in this game, Bill Wall.

7.dxe5 

Or 7.dxc5 Nf6 (7...Be6 8.Nc3 d4 9.Ne2 Bc4 10.O-O Qf6 11.b3 Be6 12.Nxd4 Qg6 13.Nxe6 Kxe6 14.f4 Ng4 15.f5+ Black resigned, stretto - JAVAWO, FICS, 2008) 8. O-O Nxe4 9. Bf4 Ng6 10. Bxc7 Qh4 11.

Stockfish 8 prefers 7...Ne7 8.Qf3+ Kg8 9.O-O Be6 10.Nc3 Qd7 with an advantage to the second player.

8.O-O Nh6 

Development, and planning to castle-by-hand if allowed.

White has to consider the exchange of his Bishop for the Knight - whose King will the resulting open lines trouble more? 

9.Qf3+ 

White probably has a draw by repetition after 9.Qh5+ Kf8 10.Bxh6 gxh6 11.Qxh6+ Ke8, with more Queen checks to follow, but there is also the wacky 12.b4!? Bxb4 13.c3!? dxc3 14.a3!? c2!? 15.axb4 cxb1/Q 16.Qh5+ which should also lead to a draw. (Hat tip to Kenneth Mark Colby, who wrote Secrets of a Grandpatzer - that second line would be a clear "Grandpatzer draw".)

9...Kg8 10.Bxh6 gxh6 11.Nd2 Qg5 



Having chased Black's King back to g8, blocking the Rook on h8, White feels comfortable with the piece exchange. On the other hand, Black still believes that there is a possible attack on the White King - hence the Queen move.

12.Qb3+ Kg7 13.f4 Qe7 



White has hopes for his "Jerome pawns".


14.Nc4 
Be6 15.f5 Bxc4 



Black was aware that putting his Bishop on e6 would make it a target, and he relied on the text move, attacking the enemy Queen, to counter any pawn push by White.

Since White's attack on Black's King will feature a Queen check from g3, Black's best defense might be 15...d3+!?, closing off the third rank. The game would remain quite complicated, although the first player still would have the advantage. 

16.f6+ 

An awkward move to meet. White's Queen will be able to escape the attack she faces (e.g. 16...Kg6 17.Qg3+ or 16...Kg8 17.Qg3+, in both cases followed by winning Black's Queen); Black's will not.

16...Kf7 17.fxe7+ Black resigned



The discovered check allows White's Queen to escape.

Jerome Gambit: Beware the Calm After the Storm

The following game starts out with the wild Jerome Gambit, which is met by one of the wildest defenses available.

White does not deliver checkmate.

Black does not deliver checkmate.

The game becomes balanced and calm.

Then White checkmates.

Wall, Bill - Guest699499
PlayChess.com, 2017 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



This is Black's sharpest response to 6.d4. I have often called it a "pie-in-the-face variation".

7.O-O Ng4 8.h3 Bb6

Probably Black's best move. Bill has faced

9.hxg4 Nf6 

Black is not too upset at having lost his Knight, as he plans to move the other one into the attack.

Two other ideas:

9...h5 10.Qf3+ Ke8 11.g5 Bxd4 12.Qd3 Bb6 13.Nc3 Ne7 14.Na4 Ba5 15.a3 c6 16.f4 d6 17.Be3 Bc7 18.Bd4 b5 19.Nc3 Rf8 20.Ne2 Bg4 21.Nc3 Bd7 22.Ne2 Rf7 23.Rf3 c5 24.Bf2 Qg4 25.Rg3 Qe6 26.Re1 Ba5 27.b4 cxb4 28.axb4 Bxb4 29.c3 Bc5 30.Bxc5 dxc5 31.f5 Qe5 32.Qd2 b4 33.cxb4 Qxe4 34.g6 Rxf5 35.Re3 Qxb4 36.Qxb4 cxb4 37.Ng3 Rg5 38.Rxe7+ Kf8 39.Rf7+ Kg8 40.Nxh5 Rxh5 41.Rxd7 drawn, Wall,B - NN, lichess.org,  2016; and

10.g5 Ng4 11.Qf3+ Ke8 12.Qh3 Qxh3 



Leading to a situation similar to what we recently saw in Wall, Bill - Guest709079, PlayChess.com, 2017 (1-0, 30) - Queens are exchanged, and Black's Knight is trapped. Quirky.

13.gxh3 Nxf2 14.Kxf2 Bxd4+ 15.Kg2 d6 



The game has reached a balance. Should either player be pleased with this? Black started out after a few moves with a "won" position, so he may not be happy. White threw a whole lot into a wild attack, so he may wish for more than a split point.

16.c3 Be5 17.Nd2 Bd7 18.Nf3 Bc6 19.Bd2 Bxe4 20.Rae1 Bc6 21.Bf4 Rf8 22.Bxe5 dxe5 23.Rxe5+ Kf7 



24.Kg3 Kg8 25.c4

Stockfish 8 slightly prefers 25.Rf2, keeping the game level. The Rook eventually gets there.

25...Rad8 26.Re3 Rf5 27.h4 Rdf8 28.Rf2 Rf4 29.b3 Bd7 



30.Rfe2 Rg4+ 31.Kh2 Bc6 32.Ne5 



Looking to squeeze something more out of the position.

32...Rxh4+ 33.Kg3 Rff4 34.Rd2 Re4 



Looking to swap Rooks, and enjoy a guaranteed draw, while hoping to make something out of his extra Kingside pawn?

Black has overlooked something.

35.Rd8+ Black resigned

Jerome Gambit: This Just Doesn't Seem to Be Her Day

In the Jerome Gambit Black's King is often the center of attention - being attacked. However, in the following game Black is able to place his King in a secure location; it is the Queen, instead, that faces all of the danger.

Wall, Bill - Banken
lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 



6...Bb4+ 7.c3 Bxc3+ 8.bxc3 Ng6 9.O-O 



The immediate 9.e5 was seen in Wall,B - PassCapture, lichess.org, 2016 (1-0, 22).

Which will prevail, the pawns or the piece?

9...Nf6 10.e5 Ne8 11.f4 Rf8 12.f5 Nh4 



The "Knight on the rim" is beginning to look rather "dim".

13.Qh5+ Kg8 14.Bg5 Rxf5 15.Rxf5 Nf6 



To save the Queen.

16.exf6 Qf8 17.f7+ Kh8 18.Qxh4 d6 19.Be7 Black resigned



Wow. Not one of her better days.

Jerome Gambit: Different Route, Same Destination

Once again, White's Queen and the "Jerome pawns" work together to harass Black and his King. Checkmate is probably a relief.

Wall, Bill - Lawliet, Lucas
lichess.org, 2016

Jerome Gambit Rematch

The following rematch (see "Jerome Gambit: More Pie, Please ") shows Black, once again, ready for his opponent's Jerome Gambit.

Alas, he does not appear to have been completely ready for his opponent.

Wall, Bill - PassCapture
lichess.org, 2016

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



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+



We have seen this line before, most recently in Wall, Bill - NN
lichess.org, 2016 (1-0, 18). It is one of a number of ways that Black returns one of the two sacrificed pieces.

7.c3 Bxc3+ 8.bxc3 Ng6 



As I have previously written:
The Knight... could also go the other way, although Bill has some experience with that plan as well: 8...Nc6 9.d5 (9.O-O Qf6 10.e5 Qg6 11.Qf3+ Ke8 12.Nb5 Kd8 13.Qf8+ Qe8 14.Qxe8+ Kxe8 15.Nxc7+ Ke7 16.Nxa8 Nxd4 17.Bg5+ Ke6 18.Nc7+ Kxe5 19.Rae1+ Kd6 20.Bf4+ Kc6 21.Rc1+ Kb6 22.Nd5+ Kb5 23.Rxc8 Ne6 24.a4+ Kxa4 25.Ra1+ Kb3 26.Be5 Black resigned, Wall,B-Caynaboos, FICS. 20119...Ne5 10.f4 Ng6 11.h4 Nxh4 12.Qh5+ g6 13.Qxh4 Qxh4+ 14.Rxh4 Nf6 15.e5 Ne8 16.Be3 c6 17.O-O-O d6 18.e6+ Ke7 19.g4 Nf6 20.f5 gxf5 21.gxf5 cxd5 22.Bg5 a6 23.Nxd5+ Kf8 24.Bxf6 Rg8 25.Rxh7 b5 26.Be7+ Ke8 27.Nf6 checkmate, Wall,B - ChessFlower, PlayChess.com, 2012.
9.e5 Qe7 10.O-O Nh6 11.Bxh6 gxh6 



This exchange is often a good idea, weakening Black's King's position and creating targets for White's Queen.

12.f4 d6 13.f5 Nh4 14.Qh5+ Kf8 15.f6 Qe6



The pesky "Jerome pawns" (backed by the Rook) work well with the White Queen.

16.Qxh6+ Ke8 17.f7+ Kd7 18.Qxh4 Rf8 19.Rf6 Qe7 



(It is useful, once again, to point out how Black's light-squared Bishop remains on its home square, and, in turn, Black's Queenside Rook. White's development rules the day.)

20.Na3 dxe5 21.dxe5 Qxa3 22.Rd1+ Black resigned



Checkmate comes quickly after 22...Qd6 23.Rfxd6+ cxd6 24.Qf6.

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.
