Jerome Gambit: Certain Lines Have Become Very Popular

cartoon detective examining footprints

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) has become popular with club players, of late, and certain lines have become very popular. The following game is an example of the kind of attack that can develop, but there are some good recent games in the notes, too, that are worth playing over, as well.

Jerome Gambit: Danger on the f-File


White's Bishop sacrifice in the Jerome Gambit brings the enemy King to the f-file. Often, Black's defense brings his Queen there. After White castles - the f-file can become a dangerous place, as the following game shows.

Wall, Bill - Guest744598
PlayChess.com, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 



7.Qxe5 Qe7 

Whistler's Defense, named for Lt. G. N. Whistler, secretary of the Lexington, Kentucky Chess Club, who played a correspondence match using the line against Alonzo Wheeler Jerome, in 1876.

8.Qf4+ Qf6 9.Qg3 Bd6 10.f4



A small improvement over 10.Qc3, seen in Wall,B - Guest3289310, PlayChess.com, 2012:  10...Qxc3 11.Nxc3 Be5 12.O-O Bxc3 13.bxc3 d6 14.d4 Ne7 15.f4 Rf8 16.d5 Kg8 17.Re1 Bd7 18.c4 Rae8 19.Rb1 b6 20.e5 dxe5 21.fxe5 Nc8 22.e6 Ba4 23.Re2 Nd6 24.Rb4 b5 25.c5 Nc4 26.g4 a5 27.Rb3 Bxb3 28.cxb3 Rf3 29.bxc4 bxc4 30.d6 cxd6 31.cxd6 Rd3 32.d7 Ra8 33.Rd2 Kf8 34.Rxd3 cxd3 35.Ba3+ Kg8 36.e7 Kf7 37.d8=Q Rxd8 38.exd8=Q Black resigned.

10...Bxf4

This  pawn grab is not as good as Bill's suggestion, 10...Bc5

11.Qb3+ Qe6 

Better, 11...d5

12.O-O 

12...Qxb3 13.Rxf4+ Kg7 14.axb3 d6 



15.d4 Ne7 16.Nc3 Bd7 17.Be3 a6  



Black safeguards his a-pawn before moving his Rook. However, this gives up a vital tempo that turns over the f-file to White.

18.Raf1 Rhe8 

Normally, Black could challenge the file, say, with 18...Rhf8, but here it would be met by 19.Rxf8 Rxf8 20.Bh6+ followed by 21.Rxf8.

19.Rf7+ Kh8 20.Bg5 Nc6 21.Bf6+ Kg8 22.Rxd7 



Black resigned

If he challenges along the f-file, he is liable to run into the notorious chess "windmill", giving up material - 22...Rf8 23.Rg7+ Kh8 24.Rxc7+ Kg8 25.Rg7+ Kh8 26.Rxb7+ Kg8 27.Rg7+ Kh8 28.Rc7+ Rxf6 29.Rxf6 Nb4 30.Rff7, when checkmate is coming.

Jerome Gambit: Initiative


Cartoon tugboat

The following game shows White grabbing the initiative and pressing for advantage. This forces Black's pieces back, and then the defender is unable to deal with what follows. 

Wall, Bill - anonymous
lichess.org, 2020

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

A reasonable response.

This might look surprising, but Bill was 7-0 against it before this game.

Black has castled-by-hand.

White starts his pawns forward to grab the initiative.

20.f4 Nc7 21.f5 Qf7 

The Queen would be safer at h5. 

22.e6 dxe6 23.fxe6 Qxf1+ 

A tactical oversight.

24.Rxf1 Rxf1+ 25.Kxf1 Bxe6 

After 25...Nxe6, Black would have a Rook and a Knight for a Queen and a pawn.

26.Bxc7 Black resigned

Jerome Gambit: The Pawns! The Pawns!



The following game illustrates the classic battle between the "Jerome pawns" and the extra piece that the defender has. Clearly, the pawns have the upper hand throughout most of the game.

Wall, Bill - Anonymous
lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Nc6 



This is a reasonable response to 6.d4, although it allows White to follow up with another thematic Jerome Gambit move.

7.Qh5+ Kf8 

Bill has also seen 7...g6, in Wall,B - Lamjung, lichess.org, 2017 (1-0, 21)

8.Qxc5+ Qe7 

Equally good is 8...d6, as in Wall,B - Guest649850, PlayChess.com 2017 (1-0, 26) 

9.Qxe7+ Ncxe7 10.c4 Nf6 11.Nc3 d6 12.f4 Be6 



A pretty dramatic contrast, White's pawns vs Black's extra piece.

13.d5 Bd7 14.e5 dxe5 

This is a tough choice.  Retreating the Knight with 14...Nfg8 might have been a little better. 

15.fxe5 Ng4 16.e6 Be8 17.O-O+ Kg8 



White's pawns are annoying - and they aren't finished.

18.Bf4 Rc8 19.c5 Nf6 20.d6 cxd6 21.cxd6 



21...h5

This does not solve Black's problems.

Bill recommends 21...Nc6 22.Bg5 when it will be difficult for the defender to avoid returning material. 

22.Bg5 Kh7 23.Rxf6 gxf6 24.Bxf6 Rg8 25.Bxe7

Jerome Gambit: Easy Does It

cartoon polar bear relaxing

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is largely known for its wild "Bashi-Bazouk" style of attack. However, in the following game, Bill Wall, with over 950 games in The Database, shows he can play the Jerome slow and easy, as well.

Black believes he has trapped White's offside Knight. He is mistaken. In his attempt to hold things together, he surrenders his advantage. 

11.Qb3+ d5 

Bill suggests 11...Kg6 12.Qxb5 Qe8 and White has grabbed the pawn, but he still has work to do.

12.Qxb5 Qd6 

This move doesn't work. Why not?

13.exd5 Qxd5 14.Qxc6 Qxc6 15.Nxe5+ Ke6 16.Nxc6 Bb6


White is now ahead 3 pawns, and Black's Bishop pair and slightly better development are not adequate compensation.

17.Bf4 Nd5 18.Rfe1+ Kf5 19.Re5+ 



This looks like a simple attempt to exchange his Bishop for the Knight, but it is more than that.

Very nice.

Jerome Gambit: A Cautionary Tale


The following 1-minute, no increment, game starts off like a "normal" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, but quickly becomes an exercise in Run For Your Life! Lessons about the opening are swiftly replaced by lessons about  intuition and rapid manual dexterity.

I know that the Jerome Gambit is often best played at high speed, but this game left me breathless...

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 



7.f4 Bf2+ 

This counter sacrifice is seen in other lines of the Jerome Gambit, followed by a forced exchange of Queens. Here, it seems to be more of a "If you sacrifice to prevent my King from castling, I will sacrifice to prevent your King from castling" kind of thing. Its psychological value in a 1-minute bullet game is clear: there is not a lot of time for White to answer the question "Just what is he doing?"

Now, if Black had time, he could force the exchange of Queens, after all, with ...Qh4+ - but White acts decisively first.

White has enough material to win. Does he have enough time?
