Jerome Gambit: Sometimes I Don't Understand, I Just Enjoy

Sometimes I visit the GameKnot.com chess site and pick up a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game or two. (I would collect more, using their Games Database feature, but I am not a regular member.) The following one is a few years old, but it has the typical Jerome je ne sais quoi that sets it apart from other contests.

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

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Ne7 

Black's idea is familiar, even if it shows up in only a few games in The Database: If he has to give back a piece, don't waste time deciding on which on, just develop another.

7.Qh5+

A bit better is probably 7.dxc5 as seen in a couple of games: 7...Re8 (7...Rf8 8.Qh5+ N5g6 9.Qxh7 Rh8 10.Qxh8 Qxh8 11.O-O d6

FICS, 2012.

Also seen was 7.dxe5 Rf8 8.Nc3 Kg8 9.O-O Ng6 10.Qd5+ Kh8 11.Qxc5 d6 12.exd6 cxd6 13.Qe3 Qf6 14.Nd5 Qe7 15.Nxe7 Nxe7 16.f4 h6 17.e5 dxe5 18.Qxe5 Nc6 19.Qd6 Bg4 20.Qg6 Bf5 21.Qg3 Nd4 22.Qf2 Nxc2 White forfeited on time, stretto - svadali, FICS, 2008.

7...N7g6 8.dxc5 d6 9.f4 

A standard "tool" from White's "toolbox", although Stockfish 7 suggests development with 9.h3 Re8 10.O-O Kg8 11.Nc3 b6 12.Bg5 Qd7 13.cxd6 Ba6 14.Rfd1 cxd6  first, then 15.f4.

In the game, Black is able to force an exchange of Queens when White does not have enough dynamic pawn play in the middle game to balance the sacrificed piece. The attacker will develop, castle, and begin to pressure his opponent, but he will need some help to prevail - and, oddly, he receives it.

9...Bg4 10.Qg5 Qxg5 11.fxg5 dxc5 12.Nc3 c6 13.O-O+ Ke7 14.h3 Be6 15.Be3 b6 16.Ne2 Nc4 

Here Black resigned after playing his move. I don't know why. Most likely the real world intervened, and he needed to return there.

Some time back, I presented a series of Jerome Gambit Quizes on this blog, to test how well Readers understood the opening. With an explosion of attention the last few months, it seems timely to present them again, to get everyone tuned into 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

No Jerome Gambit? All Is Not Lost

From a recent letter from chessfriend Roger

Our opponents won't always play the Giuoco Piano and very often play the Two Knights defense. I also find it difficult to steer the game to the good Jerome gambit lines from the Two Knights. However, there's a good way to load up on the f7 pawn using the Perreux variation (aka The Morphy Win'Mill). Here's a good example:

RK -KP
Internet, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 

4.d4 exd4 5.Ng5 Ne5 6.Bb3 Bb4+ 

7.c3 dxc3 8.bxc3 Bc5 9.f4 Neg4 10.Bxf7+ Kf8 11.Ne6+ Black resigned 

Neat finish! Black did not make it to a dozen moves.

Many thanks for sharing, Roger!

I have struggled with the Two Knights, as indicated in a number of blog posts, including"Jerome Gambit vs Two Knights Defense" Part 1, 2, 3 & 4.

Probably the best coverage of the Perreux Variation appears in Michael Goeller's analysis pages (with a measured further personal assessment) at his The Kenilworthian site. For fast and fun games, the Perreux can be the ticket.

It is also enjoyable to read Michel's essay on "Chess Amateurism".

There is a lot to be uncovered by searching the internet, but I wanted to mention a selection of relevant games at RedHotPawn.com.

Jerome Gambit: Chaos Rules

I enjoy playhing over the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games of ZahariSokolov playing at FICS. He shows an understanding of the opening, and brings a creativity that expands its impact.

In the following very difficult, complicated game, however, his opponent presents an odd, rarely-played defense, and the game quickly leaves recommended play. Still, it takes oversights on both sides before the winner is finally decided.

standard, FICS, 2015

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

4...Kxf7 5.Nxe5+ Ke7

Here we have the "Jerome Gambit, Paulsen Variation", otherwise known as "An Odd Line in an Odd Line". It is more of a psychological ploy than a solid defense - but, in this game at least, it is successful.

6.Nc4 

Electing to retain his Knight. In similar situations (see below) it can be exchanged to double Black's pawns.

6.Qh5 is the strongest response, although there are not many examples in The Database: 6...Qf8 (6...d6 7.Qf7# stivb_99 - spymaster, GameKnot.com, 2008) 7.Nxc6+ (7.0–0 d6 8.Ng6+ hxg6 9.Qxh8 Nd4 10.Na3 Ne2+ 11.Kh1 Be6 12.d4 Bxd4 13.f4 Qf6 14.Nb5 Bb6 15.Bd2 a6 16.Nc3 Nxc3 17.Bxc3 Bd4 18.e5 dxe5 19.fxe5 Qxe5 20.Bxd4 Qxd4 21.c3 Qe5 22.Rae1 Qd5 23.Qxg7+ Kd6 24.Rd1 Qxd1 25.Rxd1+ Kc6 26.Qxg6 Black resigned, guest1200 – satmonger, Internet ChessClub, 2001) 7...dxc6 8.Qxc5+ Ke8 9.Qxf8+ Kxf8 10.c3 Nf6 11.d3 Kf7 12.0–0 Rf8 13.f4 Kg8 14.f5 Bd7 15.h3 Rae8 16.g4 h6 17.Bf4 Rc8 18.Nd2 c5 19.Nf3 c6 20.Nh4 Rf7 21.c4 Rd8 22.Ng6 Be8 23.Rf3 Rfd7 24.Ne5 Re7 25.Rd1 Nd7 26.Nxd7 Rexd7 27.Kf2 Bf7 28.Ke3 Kf8 29.h4 Ke7 30.g5 hxg5 31.hxg5 Ke8 32.g6 Bg8 33.Rh3 Kf8 34.Rh8 b5 35.b3 a5 36.Rdh1 Rxd3+ 37.Ke2 R3d7 38.Bg5 Re8 39.Ke3 bxc4 40.bxc4 Rd4 41.R8h4 Rxc4 42.Rb1 Rb4 43.Rxb4 cxb4 44.Kd3 Rc8 45.e5 Rd8+ 46.Kc2 Rc8 47.f6 c5 48.f7 Bxf7 49.gxf7 Kxf7 50.Rc4 Ke6 51.Bf4 Kd5 52.Kb3 a4+ 53.Kxa4 Kxc4 54.e6 Re8 55.Ka5 Rxe6 56.Bc7 Kc3 57.Bb6 c4 58.Bc5 Re5 59.Kb5 b3 60.axb3 cxb3 61.Kc6 Rxc5+ 62.Kxc5 b2 63.Kd5 b1Q 64.Ke6 Qb5 65.Kf7 Kd4 66.Kxg7 Qc6 67.Kf7 Ke5 68.Kf8 Qd7 69.Kg8 Kf6 70.Kh8 Qg7 checkmate, UNPREDICTABLE - aladu, FICS, 2009.

6...Ne5

Black's best response is 6...d5, which would be a TN, keeping his advantage.

7.d3

White should simply take the Knight on e5 and be better. With the text, he returns the advantage to his adversary.

One wonders if one of Alekhine's cats jumped on White's keyboard. 

7...Nxc4 8.dxc4 h6 9.Nc3 c6 10.Qg4 Qf8 11.O-O Kd8 12.Be3 Be7 13.e5 d6 14.Qh5 

14...Kc7 15.exd6+ Bxd6 16.Ne4

A slip. Better was 16.c5 Be7 17.Qd5+. 

16...Nf6 17.Qf3 Bg4 18.Qf4

Perhaps Stockfish 7's suggestion held out more hope: 18.Bf4 Bxf3 19.Bxd6+ Qxd6 20.Nxd6 Kxd6 21.gxf3. 

18...Bxf4 19.Bxf4+ Kc8 20.Nd6+ Kd7 21.Nxb7 Be2 22.Rfe1 Bxc4 23.Rad1+ Bd5 24.c4 Kc8 25.Nd6+ Kd7 26.cxd5 Nxd5 27.Bg3 

White has been fighting back fiercely since losing his Queen, and he is helped by Black's next move, which actually gives the attacker the advantage in the game. Perhaps time problems?

27...Re8 28.Ne4

A missed opportunity for White, as he had 28.Rxe8 Qxe8 29.Nxe8 Rxe8 with a small advantage.

Black is now able to move on to victory. 

28...Re6 29.f3 h5 30.Rc1 Rg6 31.Nc5+ Kc8 32.Ne6 Qb4 33.Rb1 Qb6+ 34.Bf2 Qa6 35.a3 Re8 36.Nc5 Rxe1+ 37.Rxe1 Qc4 38.Ne4 Qb3 39.Nc3 Nxc3 40.bxc3 Qxc3 41.Re8+ Kd7 42.Re1 Qxa3 43.Bh4 Qb4 44.Kh1 Qxh4 White resigned

An Unexpected Success

After being schooled in our Jerome Gambit game in a Chess.com "Italian Game thematic tournament" I expected my opponent would march through the rest of his play without a loss, and score 7.5 / 8.0 to take top honors a point ahead of me.

Much to my surprise, I recently learned that he had some complications in his non-chess life, and had to forfeit several of his uncompleted games.

This allowed me to finish in first place, with 6.5 / 8.0.

That was 2.5 / 3.0 with the Jerome Gambit, too, which was not as unexpected.

(Let's see: 4 / 5 = 80% for non- Jerome games; 2.5 / 3 = 83% for Jerome Gambit games. Not bad.)

Jerome Gambit: Crashing on Through

Chessfriend Roger sent another one of his interesting internet Jerome Gambits.

Playing over the game, I was fascinated by White's "self-inflicted" backward pawn at e4 - and, apparently, Black was, too, as he quickly jumped a Knight into the created "hole".

Ah, but we should have been watching the advancing f-pawn, which spearheaded an attack which crashed on through.

A very interesting lesson!

Black looks comfortable. He needs to find a way to develop his Bishop, and then the Queenside Rook. Too many times the Jerome Gambit defender finds himself down those two pieces, as they remain out of action and unable to help meet an attack. Fair warning!

13.Qg3 Qe8 14.f5 Ne5 

Who can argue with that wonderful Knight on e5? Fine, let him have his day of glory, but pay attention to what else is going on.

15.f6 N7g6 16.Nd5 Qd7 

Not the best defensive move. Also, see the note to move 12.

17.fxg7 Kxg7 18.Rxf8 Kxf8 19.Rf1+ Nf7 20.Bh6+ Ke8 

It looks like Black has missed the fact that this move will lose his Queen, but if the King had gone to g8 the Queen would soon be lost, anyhow - and the King checkmated, to boot.

21.Nf6+ Kd8 22.Nxd7 Bxd7 23.Rxf7 Black resigned
