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.

ZahariSokolov - mmamaju
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

Sang Froid


The ongoing RedHotPawn.com Jerome Gambit tournament continues to produce interesting and educational games.

Be sure to follow the games in the notes, too, for extra excitment!


golddog2 - deriver69
Giuoco Piano Jerome Gambit Tournament
RedHotPawn.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 7.Nc3 



Sang froid. White answers Black's wild counter-attack (which leaves two pieces en prise; see "A Pie-in-the-Face Variation") with a rare, but simple developing move. Anything is worth a try in such a precarious position.

For the adventurer with White, despite what a computer player might say about the position, it is reassuring to know that in 222 games in The Database, White scored a scintillating 67%!

7...Bb4

Instead, 7...Nd3+ was the odd idea of the coputer Milobot, in a crazy game that veered all over the place: 8.cxd3 (8.Qxd3) 8...Bf8 (8...Bxd4) 9.Qf3+ (9.Qb3+ or 9.O-O) 9...Qf6 10.Qh5+ Qg6 11.Qd5+ Ke8 12.O-O a6 13.f3 Ra7 14.Bf4 b5 15.Bxc7 Nh6 (15...Rxc7 16.Qe5+ Kd8) 16.f4 Qf7 (16...Rxc7) 17.Rae1 (17. Qe5+) 17...Qg6 (17...Rxc7) 18.f5 Qg4 $18 19.Qe5+ Be7 20.Bd6 Qxg2+ 21.Kxg2 Kf8 22.Qxe7+ Kg8 23.Qf8 checkmate, LeoJustino - MiloBot, FICS, 2012. Wow.

7...Ng4, like the text in the game, also preserves Black's advantage 8.Qf3+ (8.g3 Qf6 9.Qxg4 Bxd4 10.Nd5 Qxf2+ 11.Kd1 d6 12.Qh5+ g6 13.Qh4 Qf3+ 14.Kd2 Qxh1 15.c3 Qg2+ 16.Kd3 Be5 17.Bh6 Qh3 18.Qd8 Qxh6 19.Qxc7+ Ke8 20.Rf1 Qg7 21.Qc4 Be6 22.Nc7+ Kd7 23.Qxe6+ Kxc7 24.

8.dxe5 

The wildness continued after 8.O-O with 8...Ng4 9.h3 h5 10.Qf3+ Qf6 11.hxg4 hxg4 12.Qxg4 Bxc3 13.bxc3 Qh4 14.Qf5+ Nf6 15.f3 d6 16.Qf4 Qxf4 17.Bxf4 b6 18.e5 Nd5 19.Bd2 Ba6 20.Rf2 dxe5 21.dxe5 Rae8 22.f4 g6 23.Re1 Ke6 24.g4 Rhf8 25.Kg2 Ne7 26.Kg3 Bb7 27.c4 c5 28.Bc3 Ba6 29.Re4 Rd8 30 a4 Rd1 31.Rh2 Rg1+ 32.Kf3 Bb7 33.Ke3 Rxg4 34.Rf2 Black forfeited on time in a winning position,  PLURkidIT - CEZRUN, FICS, 2007.

8...Bxc3+ 9.bxc3 Qxe4+ 10.Qe2 Qxe2+ 11.Kxe2 Ne7 



A lot of the tension has been taken out of the position, and with only a pawn for his sacrificed piece, White needs to find a way to make use of his open lines and Black's slightly unsafe King.

This time, he is not successful.

12.c4 b6 13.g4 Bb7 14.f3 Rae8 15.Bb2 Ng6 



16.Kf2 Nxe5 17.Bxe5 Rxe5 18.Rad1 d6 19.Rd3 Rhe8 20.Rf1 Re2+ 21.Kg3 Rxc2 22.Rd4 Ree2 23.h3 g5 24.f4 Re3+ 25.Rf3 Rxf3 checkmate

Another RHP Jerome Gambit Tournament - Game 2


If you are playing an opening that is "off the beaten path" and your opponent takes you off of that path, is it a good thing or a bad thing? In the following game Black's opening creativity serves him much less well than following the stodgy main line of the Jerome Gambit.

jankrb (2055) - Red House (1588)
Giuoco Piano Jerome Gambit tournament, RedHotPawn, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Ke7




Of the almost 4,600 games in The Database which reach the position after White's 5th move, only 9 show Black's 5th move response, with the simple Knight recapture being the most popular alternative. See "An Odd Line In An Odd Line" and "Jerome Gambit, Paulsen Variation".


6.Nxc6+


Best play now appears to be 6.Qh5! which appeared in 3 games: guest1200 - satmonger, Internet Chess Club, 2001 (1-0, 26); stivb_99 - spymaster, GameKnot.com, 2008 (1-0, 7);  and UNPREDICTABLE - aladu, FICS, 2009 (0-1, 70).


Each time, Black missed the best defense, pointed out by Rybka, 6...Bxf2+!? 7.Kxf2 Qf8+ 8.Nf3 Nf6, although White would still have an edge.


6...bxc6


Stronger was 6...dxc6, preventing the White d-pawn from advancing 2 squares, as in perrypawnpusher - salla, blitz, FICS, 2010 (1-0, 31).


7.d4 Bb6


There is no need to repeat the offbeat 7...Bb4+, from CoachCrupp - zzzozzzo, FICS, 20088.c3 Bd6 9.Bg5+ Nf6 10.e5 Bxe5 11.dxe5 Kf8 12.0-0 h6 13.exf6 gxf6 14.Be3 d5 15.Bc5+ Kg8 16.Nd2 h5 17.Nf3 Bg4 18.Qd3 Bxf3 19.Qg6 checkmate.


8.Bg5+ Nf6 9.e5 Ba6 


10.exf6+


An interesting try, according to Houdini, is 10.Qf3!? Kf7 (not 10...Bxd4 11.Bxf6+ gxf6 12.Qxf6+ Ke8 13.Qxh8+ Ke7 14.Qxh7+) 11.Nd2 h6 (a bit better than 11...Bxd4 12.exf6 Re8+ 13.Ne4 Rxe4+ 14.Qxe4 Bxb2 15.Rb1 Bxf6 16.Qf3 Qe7+ 17.Kd1 Re8 18.Bxf6 gxf6±) 12.Be3 Re8 13.0-0-0 and White has an advantage as he will recover his sacrificed piece.


10...gxf6 11.Be3 Qg8 12.Rg1 Re8 13.a4 c5 14.a5 cxd4 15.axb6 dxe3 16.Rxa6 axb6 17.fxe3 Qg5



Both Kings remain uneasy, but White has an extra piece which he can make use of as soon as he consolidates his position.


18.Qf3 Kf7 19.Kd2 Re7 20.Nc3 Rhe8 21.Nd5 Re4 22.Nf4 Qc5 23.Ra3 Qe5 24.Rd3 Qa5+ 25.c3 Qb5 26.Qh5+ Qxh5 27.Rxd7+ Black resigned

Jerome Gambit Doctor


Periodically in this new year we will be looking at different lines in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and be providing ideas (and study material) which may deliver "first aid" or heavier "fixes" in situations where White's play has been injured.

Here is a game by HauntedKnight, a regular player of things Jerome. He has 144 games in The Database, scoring an over-all 49%, which is the over-all average for White in those 27,400 games. With the Jerome Gambit proper he scores 42%, which is comparable to the 43% of all Jerome Gambit games in The Database.


HauntedKnight - Josue

standard game, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Be7 




Josue, the higher-rated player, chooses a very reasonable, if unpopular line. The Database has only 12 games with this move, but White has scored only 38% against it.


7.dxe5


White avoids the ostentatious 7.f4 which brings a lot of visual excitement, but more "flash" than "bang": 7...Nc6 8.d5 Nb4 9.a3 Na6 10.0-0 Nf6 11.e5 Ne8 12.Qh5+ g6 13.Qh6 Bf8 14.Qh3 d6 15.e6+ Kg7 16.b3 Be7 17.f5 Nf6 18.Bb2 c6 19.c4 cxd5 20.Nd2 dxc4 21.Ne4 Nc5 22.Nxf6 Bxf6 23.Bxf6+ Qxf6 24.bxc4 b6 25.Qg3 Bb7 26.Qxd6 Rad8 27.Qf4 Rd4 28.Qe3 Re4 29.Qd2 Rd8 30.Qf2 g5 31.Rad1 Red4 32.Qf4 Rxf4 White resigned, wirerabbit - SimpleOne, FICS, 2007

9...Nh6


Black is planning something wicked, a threat that shows up in several of the above games. Probably his best move was 9...dxe5.


10.Nc3 


It is prudent to note here that White can take the draw with 10.Bxh6 gxh6 11.Qh5+ Kf8 12.Qf3+ Kg7 13.Qg3+ Kf7 14.Qf3+ Kg8 15.Qb3+ Kg7 16.Qg3+ Kf7, etc.


If White wants to play on, it would seem that 10.Qh5+ Nf7 11.exd6 followed by 12.Nc3 would be best.


10...Bg4 


The unhappy point: White will lose his Queen.


11.Qg3 Bh4 12.Qf4 Rf8 13.Qxf8+ Kxf8 




White continued the fight, but it was too much.

(This time I saw it)

Early last year I played a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) against Banassi (see "Platypus Perils and Follies"), and succeeded when my opponent lost his way in a complicated refutation line.

Although I won the game, I was so nervous at the time that I overlooked a checkmate-in-one along the way.

This time, I saw it.

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


One of the many ways to defeat the Jerome Gambit, others being 6...g6, 6...Ng6 and 6...Kf8.

7.Qf5+ Kd6 8.f4 Qh4+


Wow!

The simpler 8...Qf6 was an effective defense, as was 8...Qd8, or 8...Qd7 or even 8...Kc6. The text holds the promise of a Queen sac, however.

9.g3 Nf3+ 10.Kd1


Now Black has 10...Ne7 11.e5+ Kc6 12.Qe4+ d5 13.exd6+ Nd5 14.gxh4 Bg4

10...Qe7 


Taking the Queen out of danger, but allowing...

11.Qd5 checkmate
