Jerome Gambit: Against the Titans (Part 1)

Image result for free clip art titan

Sitting at the computer the other day, I suddenly decided to challenge one of the programs to game of chess. I played the Jerome Gambit, of course. I've done this before - see "Jerome Gambit: Artificial Piffle" and "Contempt?!

Quickly we raced toward one of the more deadly refutations, a trip down memory lane for me that was lined with past escapes - and non-escapes. Suddenly, my opponent came up with a novelty that undid all of its hard work. The rest of the game was a combination of me timidly moving forward, while the computer seemed to lose much sense of things. Come, see. 

perrypawnpusher - Chess Titans
casual game, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5. Nxe5+ Nxe5 6. Qh5+ Ke6 



7.Qf5+ Kd6 8.f4 Qh4+ 



The first example that I have found of this move appeared in the American Chess Magazine of June 1899, in a satirical piece titled "A CHESS SCRAP" by "R.F.", which presented a supposed new-fangled thing - a chess game played over the telephone. The move is not a joke, however.

Interestingly enough, when I reported on last year's game against Chess Titans, I noted
I was pretty sure that my opponent was not seriously booked up on the Jerome Gambit, and that the killer move 8...Qh4+!? was not going to show up now.
Back then, it played the insufficient 8...g6. This time, it appeared to be better prepared.

9.g3 Nf3+ 

Black can quietly remove his Queen to f6, but the text is more aggressive.

10.Kf1

I have also played 10.Kd1perrypawnpusher - electrahan, blitz, FICS, 2009 (1-0, 35); perrypawnpusher - Banassi, blitz, FICS, 2009 (1-0, 28); perrypawnpusher - fortytwooz, blitz, FICS, 2010 (1-0, 11); perrypawnpusher - javistas, blitz, FICS, 2010 (1-0, 11); and perrypawnpusher - thinan, blitz, FICS, 2010 (1-0, 11).

The text is best, but, it still leaves Black better.

10...Nxh2+

As I have suggested, "Black can get away with this, but it is not best."

I actually met 10...Qh3+ (likely a mouse slip) twice, perrypawnpusher - rjbriggs, blitz, FICS, 2011(1-0, 10) and perrypawnpusher - inansoy, blitz, FICS, 2014 (1-0, 51).

I have had trouble in the past with 10...Qh6 perrypawnpusher - Temmo, Jerome Gambit thematic, ChessWorld.net, 2008 (0-1, 43) and 10...Qf6 -  perrypawnpusher - james042665, blitz, FICS, 2008, (0-1, 18); and perrypawnpusher - HarlemKnight, blitz, FICS, 2014}(0-1, 24).

I was familiar with the text move, having found it in the game Born Loser - NN, 2005 (1-0, 37) in White's unique book, Unorthodox Chess (2005).

11.Kg2

11...Qd8 

An odd move. I have faced a number of alternatives:

11...Qg4 (probably best) in perrypawnpusher - jgknight, blitz, FICS, 2011 (1-0, 68);

11...Nf6 12.gxh4 in perrypawnpusher - mikelars, blitz, FICS 2011 (1-0, 12);

11...Qe7 12.Qd5 checkmate, perrypawnpusher - intssed, blitz, FICS, 2010 (1-0, 12);

11...Qh6 in perrypawnpusher - JTIV, blitz, FICS, 2010 (1-0, 32); 

11...Qf6 in perrypawnpusher - IlToscano, Chess.com, 2016 (1-0, 18); and

11...Ne7 in perrypawnpusher - constipatedguru, blitz, FICS, 2017 (1-0, 20)

12.Qd5+ 

This move is good and easy to find. After the game, however, Stockfish 10 recommended that I ignore both the Bishop on c5 and the Knight on h2, at least at first, and play 12.Nc3!? The point is that neither Black piece can move to safety effectively - and a couple of possible Bishop moves would lead to checkmate in 2 or 3 moves.

The computer recommends 12...Nf6, which falls right away to the fork 13.e5+. The alternative, 12...Qe8, simply allows 13.Qd5+, and the Bishop will fall next move, and the Knight soon thereafter. White is better, in any event, but the computer is always looking for a "better better."

12...Ke7 13.Qxc5+ d6

Learning from the Jerome


I like to think that playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4Bxf7+) will improve my tactics, or at least point me in that general direction. I think it did in the following game.

perrypawnpusher  - Banassi
blitz FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Be7


The Hungarian Defense. No Jerome Gambit this time. (I know that some Jerome Gambit Gemeinde members – DragonTail and sTpny come to mind – fire off 4.Bxf7+ here, anyhow.)

4.0-0 Nf6 5.d3 d5 6.exd5 Nxd5 7.Nc3 Nxc3 8.bxc3 Bf5


9.Re1 Bf6 10.Ba3 Na5


Courting danger.

11.Bxf7+

There is something funny about this Jerome-style move, which I will get to later.

11...Kxf7 12.Nxe5+ Bxe5


This capture only helps White's attack. 12...Kg8 led to an even game.

13.Rxe5 g6 14.Rxa5 c6


15.Rxf5+

Of course.

15...gxf5 16.Qh5+ Ke6


Black's best move was 16...Kg7, but after the powerful 17.Bc5!? (intending to move to d4) he is in trouble whether or not he returns the exchange.

17.Re1+ Kd7 18.Qxf5+ Kc7 19.Re7+ Kb8


Moving in front of the pawns was no cure: 19...Kb6 20.Qc5+ Ka6 21.Qc4+ b5 22.Qxc6+ Qb6 23.Qe4 and White has too many threats.

20.Qe5+ Kc8 21.Qe6+ Kb8 22.Bd6+ Black resigned


A Bishop sacrifice at f7... A Knight capture at e5... A King-hunt started with Qh5+... The game ended up Jerome-ish, after all.

And the funny thing about 11.Bxf7+ – it wasn't the strongest move on the board.

White's best was to take the e5 pawn for free with 11.Nxe5 and offer to sacrifice the Bishop a different way: if Black played 11...Nxc4, White's best would be 12.Nc6+!? winning Black's Queen.

(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.

perrypawnpusher - thinan
blitz FICS, 2010

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




analysis diagram







as in abhailey - peonconorejas, net-chess.com, 2008, which finished with 15.Qa4+ b5 16.Qa6+ Nb6 17.c4 Nd4+ 18.Ke1 Rhe8+ 19.Kf2 Nf5+ 20.Kf1 Bh3 checkmate.




analysis diagram







10...Qe7 


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

11.Qd5 checkmate


This was anticipated by CoachCrupp - jirikb, blitz FICS, 2008.

perrypawnpusher - Banassi, blitz FICS, 2009 continued: 11.e5+ Kc6 12.Qe4+ Kb6 13.Qxf3 d6 14.Nc3 Be6 15.Na4+ Kb5 16.Qxb7+ Bb6 17.Nxb6 axb6 18.Qxa8 dxe5 19.a4+ Kc5 20.d3 exf4 21.b4+ Kd6 22.Bxf4+ Kd7 23.Qb7 Bg4+ 24.Kc1 Ke8 25.Qa8+ Kf7 26.Qd5+ Kf8 27.Qe4 Qxb4 28.Qxb4+ Black resigned.

Platypus Perils and Follies

Here's another example of what Gary K. Gifford, editor of the Unorthodox Openings Newsletter,  would call "the Jerome Gamble" (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). The "bet" pays off, but only after some tense – and ridiculous – moments.

perrypawnpusher - Banassi
blitz 2 12, FICS, 2009

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



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



If Black is brave – or knowledgeable – enough to play this move, his game has a good chance at a happy ending.

7.Qf5+ Kd6 8.f4 Qh4+



Ah, here is part of the "gamble": does Black know the killing Queen sacrifice, or is he just causing trouble??

9.g3 Nf3+ 

Okay, so far.

10.Kd1 Qe7



Uh, no. That would indicate "brave".


11.e5+

Incredible. Black allows a mate-in-one and White overlooks it!

Waiter! Coffee for my friend and me. None of that de-caf stuff, give me high-test!

11...Kc6



Black misses a chance for complete recovery with 11...Nxe5, since after 12.d4 Kc6 13.fxe5 d5 14.Qd3 Bg4+ he has an edge (and an extra piece).






analysis diagram





12.Qe4+ Kb6 13.Qxf3 d6



Black is not distressed with the loss of the advanced Knight (he is still a piece ahead) and, seeing the White King as vulnerable, he works to open lines in the center.

14.Nc3

After the game, Rybka gave a tortuous route to equality: 14.d4 Bxd4 15.Qb3+ Kc6 16.Qa4+ Kc5 17.Na3 Bg4+ 18.Kd2 dxe5 19.Qb5+ Kd6 20.fxe5+ Ke6 21.Qc4+ Kf5 22.c3 Be3+ 23.Kxe3 Qxe5+ 24.Kf2 Re8 25.Rf1 Qe6 26.Kg1+ Kg6 27.Bf4 Whew!





analysis diagram






14...Be6



15.Na4+

There has to be some kind of attack on the King, I thought.

That is true, but the move played should only lead to a draw. Rybka preferred 15.b4 Bxb4 16.a3 c6 17.axb4 and White is better in a tense position.

15...Kb5

This is too cooperative. After 15...Ka6 White can play to split the point with 16.f5 Qf7 17.Nxc5+ dxc5 18.Qa3+ Kb6 19.d4, with the plan for repetition of position.

16.Qxb7+


Now White does have an attack going.

16...Bb6 17.Nxb6 axb6 18.Qxa8



18...dxe5 19.a4+ Kc5 20. d3 exf4


Black continues with his plan to open up the center against the White King. He doesn't have many alternatives.

21. b4+ Kd6 22. Bxf4+ Kd7 23. Qb7 Bg4+ 24. Kc1 Ke8 25. Qa8+


White is ahead two pawns plus the exchange, and has a potential for either opening the a-file for his Rook or creating a protected passed pawn. An endgame is just fine for him.

25...Kf7 26.Qd5+ Kf8 27.Qe4 Qxb4 



A game-ending oversight, but the endgame held nothing but suffering for Black.

28. Qxb4+ Black resigned
