Jerome Gambit: In Pawns We Trust

In the Jerome Gambit White gives up a piece or two for a couple of pawns. Often he must rely on those pawns for active play against his opponent. In the following game the play first seems less-than-active, but that eventually changes, much to Black's misfortune.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.f3

Steinitz said that the player with the advantage must attack, or risk losing that advantage. White prepares to face that attack, relying on solid "Jerome pawns" instead of planning an attack of his own with f2-f4.

10...Kf7 11.O-O

Equally good is 11.d4 as in Wall,B - Guest3544144, PlayChess.com, 2013  (1-0, 35)

11...Rf8

Or 14.Nc3!?

14...Nh5 15.g3 b6 16.Qe3 Ba6 17.Re1 Qe8 18.f4 Ne7

Black misses his chance. He should try 18...Nhxf4 19.gxf4 Nxf4 20.Qg3 Ne2+ 21.Rxe2 Bxe2.

19.Qf3 g6 20.Nc3 Ng7 21.Nxd5 Qd8 22.Nxe7+

Jerome Gambit: Even in the Most Dire of Circumstances

After a tough loss with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) in the ongoing Giuoco Piano thematic tournament at Chess.com - outplayed by an opponent 200 or 300 rating points above me (not the usual "Jerome Gambit odds") - I like to play through games like the following one, where White seems to always come up with something, even in the most dire of circumstances, and in a three minute game, too!

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.d4 exd4 6.Ng5+ 

I never understand how people get away with Ng5+ in the Jerome. Probably I should find out.

6...Kf8 7. Qf3+ Qf6 8.Qg3 d6

9.Nd2 Nge7 10.O-O h6 11.Kh1 hxg5 12.f4 Ke8 13.Nc4 gxf4 14.Bxf4 Be6

19.Qg3 b6 20.Bxd4 Rh7 21.Rad1 Ke7

And, just like that, White has a forced checkmate. Wonderful!

Jerome Gambit: The Power of Surprise

I almost always root for the Jerome Gambit player (sometimes I defend against the Jerome) but in the following game I was pleased to see Black's 9th move - the best way to give White difficulties after an inexact defense. It's the first time that I have seen it played.

The game itself - 5 minute blitz - was a tense affair, with a late inexactitude by White costing him the game.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Nf6

Not the right idea, but understandable given the quick nature of the game.

8.Qxc5 

There are 61 games with this position in The Database.

8...d6

Interestingly, the best response, 8...Nxe4, shows up in only 14 of those games - 23%. That's the power of surprise in an opening.

9.Qe3 

There are 15 games with this move in The Database. 

9...Nxe4 

There were 0 games with this correct move - until this one. The Knight is safe, as a Queen capture will be strongly met by 10...Re8.

10.O-O Bf5 11.d3

More adventurous was 11.g4!?

11...Nf6 12.Nc3 Re8 13.Qf3 c6 14.Bd2 Qa5 15.Rfe1 Qb4 16.b3 Qh4 17.Rxe8 Rxe8 

White has a small advantage - a pawn.

18.g3 Qh3 19.Qg2 Qh5 20.h3  

Better is 20.f3, as the text loses a pawn. 

20...Qxh3 21.Qxh3 Bxh3 22.Bg5 d5 23.Bxf6 Kxf6 24.Kh2 Bc8 25.Kg2 b6 26.f3 Bb7 27.g4 c5 28.Kg3 h5 29.gxh5 gxh5 30.Nd1

Despite his Bishop vs Knight, and outside passed pawn, Black's edge was small until this move. White could have kept things going with 30.Rh1. 

30...Rg8+ 31.Kh4 Rg1 32.c4 dxc4 33.dxc4 Bxf3 34.Rc1 Rxd1 35.Rxd1 Bxd1 

Black is clearly winning.

Excitment in a Jerome Gambit Sideline

I recently encountered a 10-minute game played online at lichess.org that featured a rather unusual line of play for White in the Jerome Gambit - and to be "unusual" in such an unusual opening means that the play got complicated and messy, just the kind of thing that a Jerome Gambit player enjoys taking advantage of!

I have placed all (few) game examples from The Database in the notes, to give Readers an idea of how stressed play can become in the variation.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Nf6 8.Qf5+ 

The usual (and recommended) move is 8.Qxe5+, but White has an interesting idea in mind. In quick games "interesting" often equals "dangerous" and regularly becomes "entertaining". 

8...Kf7 9.fxe5 d6 

Here we have White's idea and Black's response: White's Queen stays on the f-file and pins Black's Knight, planning to win it with the pawn that has gone to e5; while Black opens up an attack on the Queen.

The alternate move of the Black d-pawn has also been seen. From The Database: 9...d5 10.Qf4 (10.exf6?

This routine, not-so-deeply-analyzed move brings trouble.

Return of the Negative Halo Effect in the Jerome Gambit

As I have pointed out before on this blog, when people notice a good trait in a person, they often assume other positives. However, with the Jerome Gambit often a negative halo effect occurs – if the early moves are bad, the defender reasons, many of the following ones must be bad, too. So - why waste time figuring out the Jerome Gambit?

The following game is a good example of this dilemma for Black.

Jerome Gambit: Surprise!

Add another win - and a loss - to my score in the ongoing Chess.com Giuoco Piano tournament (see "In Search of Eine Schach-Blindenhund...") and it is clear, once again, that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a fun and effective "surprise weapon", but can be a bit of a struggle with someone who does not rattle easily.

In fact, my 51-move loss to Altotemmi (he crushed me with an Evans Gambit, too, and leads the tournament at this point) will require some re-tooling of a particular opening variation... (I am already working on it.)

In the meantime, another critical line in an important game has got me thinking overtime as well.

Who knew that the Jerome Gambit could be as challenging as a "real" chess opening? 

Jerome Gambit: Crushing Attack on the King

Not too long ago I received a request for a copy of The Database from someone who plays the Jerome Gambit. I quickly emailed it off! Shortly later I received a very nice game from him, which I am very happy to share - see below.

RK - DR
Internet, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.O-O Nf6 

9.Nc3 Re8 10.Bg5 c6

Black would like to keep White's Knight off of d5, where it can join in the attack on the piece at f6. However, a move later he decides to use the same pawn to harass the enemy Queen. This kind of use of time can cause problems.

11.f4 c5 12.Qf2 Ned7 13.Rae1 Kg8 14.Qg3

Black has prudently castled-by-hand, but his development lags, so that even though he has an extra piece, the game is even.

14...b6

Stockfish 7 suggests the humorous 14...Nh5 15.Qf2 Nhf6 16.Qg3 Nh5 etc with a draw. I am sure that White was looking for more than a draw!

White now breaks in the center, and the attack is on.

15.e5 dxe5 16.fxe5 Nxe5 

This move adds to Black's pain.

17.Bxf6 Qd7 18.Bxe5 Bb7 19.Rf5 Re7 

Of course, if 19...Qxf5 then 20.Qxg7 checkmate.

20.Rg5 Rae8

Black said he was expecting his opponent to play 20...g6 and then he was going to crash through in a few moves with h4-h5-hxg6. He was sure 21.Rxg6+ also wins but he didn't want to exchange so many pieces (21...hxg6 22. Qxg6+ Rg7 23. Bxg7 Qxg7 24. Qxg7+ Kxg7 25. Re7+) just to be up a Knight and needing to march the g and h pawns up the board.

21.Rd1 Black resigned 

As White noted, if Black tries to save the Queen with 21...Qc8 then 22.Rxg7+ Kf8 (22...Rxg7 23.Qxg7#; 22...Kh8 23.Rg8#) 23.Rg8+ Kf7 24.Qg7+ Ke6 25.Qf6 checkmate
