Jerome's Double Gamble


Today's post's title plays on an early name for our opening, once referred to as "Jerome's Double Gambit."

As far back as the post "Jerome Gambit Tournament: Chapter IV" I mentioned that Unorthodox Openings Newsletter editor Gary K. Gifford had rightly classified our opening - "Jerome Gambit, or Jerome Gamble?" (UON #17).


Even earlier, in "But - is this stuff playable?" Part I and Part II, I had given an unqualified "no" and a qualified "yes" as answers to my question.

Maybe a more useful question would be -- "Under what conditions might the Jerome Gambit be playable?" ...[A]t the right time (and time control), with the right opponent, playing in the right mood – perhaps the Jerome Gambit is a bit playable...
In the following game, Bill Wall gives it his best shot, but seems to be facing the wrong opponent at the wrong time...

Bill has included a few suggestions.


Wall,B - Guest874250

PlayChess.com, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 d6 8.Qg3



Instead, 8.Qf4+ would be met by 8...Qf6


8...Nf6 


Possibly a bit stronger than the alternatives, 8...d5, which was seen in Wall,B - GoldCoinCollector, Chess.com, 2010 (1-0, 17); Wall,B - Thieveyen, Chess.com, 2010 (1-0, 61); Wall,B - GuestZCLK, FICS, 2011 (1-0, 15); and Wall,B - bfcace, Chess.com, 2012 (1-0, 25); and 8...Qe7 from Banks,P - Dunne,D, Worcestershire v Derbyshire, 2010 (1-0, 35).


9.Nc3


Likewise, Bill has played 9.d3, as in Wall,B - Badbeat994, Chess.com, 2010 (1-0, 48); and Wall,B - Milsrilion, Chess.com, 2010 (1-0, 50).


9...Kf7


Black tried 9...Nh5 in Wall,B - Ahmadi,S, Chess.com, 2010 (0-1, 59), but that move, alone (about equal to the text) was not responsible for the game's outcome.


10.0-0


Or 10.d3.


10...Rf8 11.d3


Another idea was 11.Qh4 Kg8


11...Be6 


Or 11...Kg8 as in perrypawnpusher - truuf, blitz, FICS, 2011 (0-1, 32).


12.Be3


Possibly 12.Kh1 Kg8 13.f4; or 12.Ne2 Nh5 13.Qf3+ Kg6 14.Nf4+ Nxf4 15.Bxf4 Qf6


12...Nh5


If 12...Bxe3 then 13.Qxe3.


13.Qf3+


Or 13.Qg5 Qxg5 14.Bxg5 Kg8.


13...Kg6 14.Qe2


Possibly 14.Qd1 Bxe3 15.fxe3 Qg5


14...Nf4 15.Bxf4 


If 15.Qd2, then 15...Qg5; but not 15.Qf3? because of 15...Nh3+


15...Rxf4


16.g3


Ideas: 16.Qd2 Qf6; or 16.e5 Bg4; or 16.Na4 Qg5.


16...Rf7 17.e5


Or 17.Nd5 Bxd5 18.exd5 Qf6; or 17.h4 Bh3 18.Rfe1? Rxf2.


17...dxe5 18.Qxe5


Attacking both bishops.


18...Qd6 


19.Qe4+


More attractive than trading Queens with either 19.Qxd6 cxd6 20.Kg2 Bd4; or 19.Rae1 Bf5.


19...Bf5


Better for White was either 19...Kh6 20.Rae1 or 19...Kf6 20.Qxb7 


20.Qxb7


Or 20.Qg2 Re8 


20...Re8 21.Qg2


White's choices are becoming limited, e.g. 21.Qb5 Re5 22.Qb7 c6; or 21.g4 Bxg4 22.Qg2 h5; or 21.Na4 Bh3 22.Nxc5 Qxc5


21...Bg4 22.Ne4 


Or 22.h3 Bf3 23.Qh2 Bc6


22...Qe5 


23.Rae1


Alternatives: 23.Rab1 Qh5 24.Nxc5 Bf323.c3 Qh523.Nxc5 Qxc5 24.c3 Bf3 25.Qh3 Be2. 


23...Bb6 


Or 23...Bf3 24.Qh3 Bb6


24.b4


If 24.c3 Qe6 25.d4 Bh3; if 24.b3 Qf5; not 24.Nc3? Qxe1! 25.Rxe1 Rxe1+ 26.Qf1 Rxf2 27.Qxe1 Rxc2+; if 24.c4 h5 25.b4 Bf3 26.Qh3 Bd4.


24...Qe7 25.a3


More solid than 25.h4 Qxb4; or 25.b5 Qd7 26.h4 Bh3; or 25.Rb1 Qd7.


25...Qd7 26.h4 


Instead, 26.Nc5 Bxc5 27.bxc5 Bf3 loses the Queen. 


26...Bh3 27.Qh1 


If 27.Qh2, then 27...Qg4.


27...Ref8


Or 27...Bxf1 28.Kxf1 h6.


28.Rc1


If 28.Re2 then 28...Qg4 29.Rd2 Be3


28...Qg4 29.Qh2 h6 30.c4 Bd4 31.Rcd1 Rf3 32.Rd2 R8f4 White resigned.

Slower...


Almost all of my games with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) played at FICS have been at blitz speed (the one notable exception being a mismatched game against MiloBot). I have decided to try the opening out at slower time controls. The following is my second non-blitz FICS game. 


perrypawnpusher - kashifnaseem
standard, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8


The Jerome Variation of the Jerome Gambit.

7.Qxe5 d6 8.Qg3 Qf6


Including this game, The Database has 47 games with this move (reinforcing Black's hold on the dark diagonals), with White scoring 50%. Of interest are the 8 games between mrjoker and PhlebasP, where the first player scored 6-1-1.

Alternatives include 8...Nf6 (64 games in The Database, White scores 52%), as in perrypawnpusher - klixar, blitz, FICS, 2007 (1-0, 33), perrypawnpusher - marianomocoroa, blitz, FICS, 2010 (1-0, 14),  perrypawnpusher - salla, blitz, FICS, 2010 (1-0, 18), perrypawnpusher - caterwaul, blitz, FICS, 2010 (1-0, 39);  perrypawnpusher - maxmi, blitz, FICS, 2010, (1-0, 42), Wall - Badbeat994, Chess.com, 2010 (1-0, 48), Wall - Milsrilion, Chess.com, 2010 (1-0, 50), and perrypawnpusher - truuf, blitz, FICS, 2011 (0-1, 32).

Also 8...Qe7 (6 games in The Database, White scores 67%) as in perrypawnpusher - frencheng, 10 5 blitz, FICS, 2010 (1-0, 17), perrypawnpusher-dkahnd, blitz, FICS, 2010 (1-0, 20) and Banks,P - Dunne,D, Worcestershire v Derbyshire, 2010, (1-0, 35); and 8...h5 (3 games in The Database, White scores 67%), as in Wall - Thieveyen, Chess.com, 2010 (1-0, 61).

9.0-0

Or 9.Nc3 as in Wall - GoldCoinCollector, Chess.com, 2010 (1-0, 17).

9...g6

Creating a refuge for his King.

10.Nc3 c6 11.d3 Be6


12.Be3 Bd4

Black sees the c3 spot as vulnerable, and figures that if White exchanges off the Bishop, the Queen will recapture and be centrally placed. This is an error that we both missed  which I realized as soon as I played my next move. This is something that I had hoped that "more time on the clock" would fix.

13.Bxd4

Too much of a reflex: after 13.Qxd6+ Black will simply lose the Bishop.

13...Qxd4 14.Kh1 Nf6 15.f4 Ng4


Eyeing the square e3, which no longer has the protection of White's dark-squared Bishop.

16.Rae1

This move is okay (protecting the square, developing a Rook) but after the game Houdini pointed out that I could have pushed 16.f5 anyhow, as I would not be losing the exchange, I would be getting two pieces for a Rook (leaving me up two pawns for the exchange): 16.f5 Ne3 17.fxe6+ Nxf1 18.Rxf1+ Kg8 19.Qg5 and White's Queen is ready to invade Black's fortress.

16...Qb4

This is the kind of move that makes my heart soar, especially after my games against irak, smarlny and chingching – it is dangerous for Black to let his Queen go wandering.

17.f5 gxf5 18.exf5 Bxa2



19.Nxa2

After the game Houdini pointed out that 19.Re4, both threatening to win the Knight at g4 and chase the Queen away from protecting the pawn at d6, was even stronger.

19...Qxb2 20.Qxd6+ Kg8 21.Qe6+ Kg7 22.Qe7+ Kh6 23.Qh4+ Kg7 24.Qxg4+ Kf6 25.Re6+ Kf7 26.Qh5+ Kf8 27.Qh6+ Qg7


I am sure that there was a checkmate after 27.f6, but, having gone up a piece, I decided to play it safe and exchange Queens.

28.Qxg7+ Kxg7 29.f6+ Kf7 30.Re7+ Kf8 31.Rxb7 Re8 32.Rxa7 Rg8 33.f7 Re6 34.Ra8+ Kg7 Black resigned

Flounder

I have slowly been increasing the rating of the players I try the Jerome Gambit on, and this has had a marked impact on my games. While once I could play my "regular" game, and pounce on my opponent's big errors, now I have to try to make something out of much lesser errors... This will continually push me to improve my game, or more results like the following will occur.

perrypawnpusher - truuf
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8


The Jerome Variation of the Jerome Gambit, played by Alonzo Wheeler Jerome against David Jaeger in correspondence, 1880.

7.Qxe5 d6 8.Qg3 Nf6

Pete Banks ("blackburne") faced 8...Qe7 over-the-board in Banks -Dunne, Worcestershire vs Derbyshire, 2010, (1-0,35);


Bill Wall has seen both 8...Qf6 (Wall,B - GoldCoinCollector, Chess.com, 2010 [1-0,17]) and 8...h5 (Wall,B -Thieveyen, Chess.com, 2010 [1-0,61]).

9.Nc3

A tiny bit better might be 9.d3, although transposition is likely.

9...Kf7 10.d3 Rf8 11.0-0 Kg8


Black has castled-by-hand and is simply better. His Bishop at c5 holds back the f-pawn, causing a change in White's strategy.

12.Bg5 Nh5

Better was 12...Be6, but who can resist attacking the Queen? 

13.Qh4 Qe8 14.Nd5 Qf7


15.c3 Be6

A reasonable move, but it has a tactical hole, so better was 15...h6.

16.Ne3

Missing a chance to grab a pawn with 16.Nxc7 Qxc7 17.Qxh5 and allowing Black to correct his last move.
16...h6 17.Bxh6 gxh6 18.g4


From here on out, my moves become more and more desperate. 

18...Qg6

An inaccuracy, although giving back a piece (he has two to spare) to exchange Queens pretty much seals my fate.

19.Qxh5 Qxh5 20.gxh5 Bh3 21.Rfe1 Kh7 22.Kh1 Rxf2 23.d4 Bb6 24.Rab1 Raf8



25.a4 R8f3 26.b4 a6 27.a5 Ba7 28.Rbc1 Rd2 29.Nd1 c5 30.dxc5 dxc5 31.e5 cxb4 32.e6 Bg2 checkmate


It is worth checking out the game references, above (all are in The Database), but this outing was not one of my better ones.

Jerome Gambit, Over-the-Board

Pete Banks ("blackburne") is known to readers of this blog. His Jerome Gambit games have appeared in Gary Lane's ChessCafe column and in the IM's The Greatest Ever Chess Tricks and Traps. Here is his latest over-the-board excursion.

Banks,P - Dunne,D
Worcestershire v Derbyshire, U-140, 2010[Notes by Pete Banks]

My opponent didn't turn up. Because his name was on the match sheet, and I made my move, I thought that I just had to wait for his flag to fall. Unfortunately the Midland Counties have a rule that allows substitutions.

1.e4 e5 2.Nf3 Nc6 3.Bc4

I might as well see if I can play it.

3...Bc5

Here we go!

4.Bxf7+

One piece sacced.

4...Kxf7 5.Nxe5+ Nxe5

Two pieces sacced after 5 moves! Now I've got a won game. (In my dreams)

6.Qh5+ Kf8 7.Qxe5

One piece back!

7...d6 8.Qg3 Qe7 9.Nc3 Nf6 10.d3 h6


I've used 4 minutes and he's used 35 (including the time waiting for his teammate).

11.Be3 Bb6 12.0-0-0

Starting to pile up my army against his exposed King.

12...c6 13.f4

I believe my friend Rick calls these (e4 and f4) the 'Jerome pawns'.

13...Bxe3+ 14.Qxe3 b5 15.h3

I've been worried about N or B g4 for some time. I'm still two pawns for a piece, but the pawns could be strong.

15...b4

I'm going to more or less ignore his attack, because I think mine is better.

16.Ne2

In an ideal world, this will go to f4 and g6 giving a family fork.

16...c5

Still no real threat that I can see.

17.f5

Whereas this stops g5, cuts off his white-squared bishop, and supports the N going to g6.

17...Bb7 18.Nf4 Qf7


That stops my multiple fork, but I still win the exchange. He hasn't got time for Qxa2 if he wants to win the N.

19.Ng6+ Kg8 20.Nxh8 Kxh8 21.b3


I've now got R + 2P versus B+N. Advantage me I think.

21...a5 22.g4 a4

I still don't think there's anything to fear if I'm careful.

23.Qg3

This hits d6, but is really so I can move h4 without allowing Nxg4.

23...axb3 24.axb3


If his Q could get across to the a-file quickly, there might be cause for concern.

24...Qd7 25.h4 d5 26.e5


I thought about taking the d-pawn, but the passed pawn seemed better.

26...Nh7 27.Qf4

This is so I can play g5 without the Q taking my f-pawn. In this game my Q spends most of its time supporting pawns.

27...c4 28.dxc4 Ra1+


I have to be a bit careful now.

29.Kb2

If 29.Kd2, dxc4+ would be dangerous.

29...Rxd1 30.Rxd1 Bc6 31.cxd5

If he takes, the B is pinned, and he will lose it.

31...Nf8


I'm not sure what that was for, but I supppose there's not much choice.

32.Qxb4 Qd8

Nice combination to finish it.

33.dxc6 Qxd1 34.Qxf8+ Kh7


The only thing to worry about now is a perpetual check. The next move stops that.

35.Qd6 Qxg4

At this stage, Black's clock fell, but my next move would be Qg6 check which definitely finishes it. 



Modern over-the-board (as opposed to via the Internet) Jerome Gambit games are hard to come by. Does anyone else play the Jerome Gambit "in real life"? - Rick
