Jerome Gambit: The Nightmare Before Christmas

Image result

I borrowed part of the title of this blog post from Tim Burton's animated film, but it seemed to be about right in describing the following game.

Those who play the Jerome Gambit need to constantly remind themselves that it is, technically, a refuted opening, and that there are a number of winning defenses that Black can play.

True, there are many circumstances which lead to the defender not making use of his advantages, and White wins - sometimes quite impressively. Learning to take advantage of any slip or error is critical.

However, sometimes there are games like the following. SeinfeldFan91 won the RedHotPawn.com Jerome Gambit tournament by succeeding in all of his games - and that means wins with Black, as well as wins with White.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




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


At first Alonzo Wheeler Jerome favored this move over 6.Qh5+, and it has much going for it - including winning back one of White's two sacrificed pieces.

A quick look at The Database (which is a good measure of club player success, not necessarily "theoretical" or computer success) shows 1,499 games with 6.d4, with White scoring 52%. This can be compared with 3,793 games with 6.Qh5+, with White scoring 55%.

6...Qh4 

This is the strongest theoretical response to 6.d4, and it appears in 230 games in The Database. However, as a measure of how chaotic the game becomes in this double-edged variation - White scores 67%!

This is another indication that familiarity and understanding of the Jerome Gambit is very important: Play what you know, and know what you play.


7.dxc5

Here the Database statistics line up with the recommendations of the computers. The text move appears in 67 games with White scoring 28% - not bad when considering that the line is "lost" for the attacker, but not best. There are 154 Database games with the also "lost" (but better) move 7.0-0, and White scores 87% - it is always good to understand your practical chances in a wild line! 

7...Qxe4+ 8.Kf1 Nf6 9.Nc3 Qb4 



Some alternatives:

9...Qh4 10.Be3 b6 11.Ne2 bxc5 12.Ng3 d6 13.c3 Ba6+ 14.Kg1 Rhe8 15.Qb3+ c4 16.Qd1 g6 17.Kf1 Neg4 18.Bd4 Nxh2+ 19.Kg1 Nfg4 20.Qd2 Bb7 21.Qf4+ Kg8 22.Rxh2 Qxh2+ White resigned, HauntedKnight - blocbloc, FICS, 2016;

9...Qc4+ 10.Kg1 Qxc5 11.Be3 Qe7 12.g3 d6 13.Kg2 Bg4 14.Qd2 Bf3+ 15.Kg1 Bc6 16.f4 Nf3+ White resigned, HauntedKnight - truuf, FICS, 2014; and

9...Qc6 10.Bg5 Re8 11.Bxf6 Qxf6 12.Nd5 Qf5 13.Nxc7 Ng4 14.Qd5+ Qxd5 15.Nxd5 Re5 16.c4 b6 17.cxb6 Ba6 18.b3 axb6 19.Nxb6 d5 20.Nxa8 dxc4 21.Nc7 Rf5 22.Nxa6 Nxf2 23.Kg1 c3 24.Rc1 Ne4 25.Nb4 Rf2 26.Rxc3 Rb2 27.Rf3+ Ke6 28.h3 g5 29.Kh2 h5 30.Re1 Ke5 31.Nd3+ Black resigned, PasChat - plamb, FICS, 2014

10.g3

At this point something like 10.Be3 to focuse on development was probably better. Still, the situation is grim.

10...d5 11.Kg2 Bg4 12.Qe1 Rhe8 White resigned



Playing on a piece down, with the loss of more material imminent, was not appealing.

BSJG: Just Take The Piece


Black usually plays the Blackburne Shilling Gambit with the idea of a sharp, short, tactical game in mind. In the following game he succeeds in achieving that, but not exactly in the manner he planned.

PasChat - olegYankee
standard, FICS, 2013

1. e4 e5 2. Bc4 Nc6 3. Nf3 Nd4 

The Blackburne Shilling Gambit.

4. Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Ke7

Of the 4,272 BSJG games in The Database (White scoring 56%), only 452 (White scoring 70%) - about 11% of the total - have this move. (Clearly accepting the Bishop, rather than declining it, has worked out better for Black)

5. Nxd4

The more mundane 5.Bxg8 was played in perrypawnpusher - michon, blitz, FICS, 2013 (1-0, 41) and  perrypawnpusher - michon, blitz, FICS, 2013 (1-0, 8)

 5...exd4 6.Bc4 Nf6

Whatever You Do, Don't Take Me Seriously


Here we have a short Jerome Gambit game whose brevity can be attributed to the defender relying on his sharp 7th move to win the game - when there was still plenty of play left in the position. Black's King went wandering, instead of staying home.

PasChat - charlyeliot

standard, FICS, 2013

1.e4 e5 2.Bc4 Nf6 3.Nf3 Nc6 4.Nc3 Bc5 5.Bxf7+



Transposing from the Bishop's Opening to the Italian Four Knights Game to the Italian Four Knights Jerome Gambit.


5...Kxf7 6.Nxe5+ Nxe5 7.d4 d5





There are many ways for White to return some of the sacrificed material. This is one of the sharpest.

8.dxe5 Ne8


Or 8...Ng4 as in perrypawnpusher - NimbusReign, blitz, FICS, 2010 (0-1, 26); or 8...Bxf2+ as in perrypawnpusher - Marcym, blitz, FICS, 2010 (1-0, 20)


Possibly best is 8... Nxe4. 


9. Qf3+ Ke6 


After the safer 9...Kg8 and then 10.exd5 White would have three pawns for the piece, and the game would probably be even. 


10.O-O


This is good, but even better is 10.Qf5+ Ke7 11.Nxd5+ Qxd5 12.Bg5+!? winning a lot of material. 


10... Bd7 


Or 10...Kd7 11.e6+ Kd6 and Black will not last long. 


11.Qf5+ Ke7 12.Nxd5 checkmate
