A Long Day In The Life of the Jerome Gambit

Sometimes Jerome Gambit games are easy, sometimes not. Sometimes they are pretty, sometimes pretty ordinary. Always they are complicated. Always they are exciting. Enjoy the following game, high notes and low.


Laaber - Ausxh,
blitz, FICS, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Ke8 6.Qh5+



The text is thematic, but 6.Nxc6 is probably better: 6.Nxc6 dxc6 7.Qh5+ g6 (7...Kf8 8.Qxc5+ Qd6 9.Qe3 Nf6 10.e5 Ng4 11.Qf4+ 1-0 Wall,B - Gebba, Chess.com, 2010) 8.Qxc5 Qe7 9.Qc3 Qxe4+ 10.Kf1 Black resigned, Wall,B - Guest1609773, PlayChess.com, 2013;

Not 6.Nxc6 bxc6? 7.Qh5+ as seen in perrypawnpusher - rodrigojalpa, blitz, FICS, 2008 (1-0, 25); perrypawnpusher - zsilber, blitz, FICS, 2010 (½-½, 42);  Wall,B - Qwerty, Chess.com, 2010 (1-0, 9); and Wall,B - LFTN, FICS, 2012 (1-0, 20), for example.

Interestingly, Stockfish 6 prefers 6.Nxc6 Qh4!?

6...g6 7.Nxg6 Bxf2+

Best!?

8.Kd1 

8.Kxf2 is playable: Blackstone,J - Dommeyer,C, Campbell, CA 1960 (1-0, 13); Philidor 1792 - Guest834593, PlayChess.com, 2014 (1-0, 16); ZahariSokolov - naijachampion, FICS, 2014 (1-0, 34).

The alternative, 8.Kf1, doesn't work if Black follows up with 8...Nf6!?, but that hasn't shown up in The Database yet, only 8...hxg6?! in jecree - lhoffman, FICS, 2008. 

8...Nf6 9.Nxh8+

White is overlooking something.

9.Qf3 was seen in Petasluk  - Klonkku, FICS, 2011 (1-0, 57). 

9...Kf8 

Black, too: 9...Nxh5.

And some thing else.

10.Qf5

Missing: 10.Qf7 checkmate. 

10...d6 11.Qxf2 

White will be up the exchange and a couple of pawns once he gives back the Knight at h8.

11...Bg4+ 12.Ke1 Qe8

Trying to mix it up again.

13.d3 

There was nothing wrong with 13.Qxf6+.

13...Kg7 14.Bg5 Nxe4 15.dxe4 Qxe4+ 16.Be3 Nd4 



White is winning, but it may not feel that way to him.

17.Nc3 Nxc2+ 18.Kf1 Nxe3+ 



19.Kg1 Qe5 20.Re1 Rxh8 21.Rxe3 Qd4


The extra Rook will help White, once it gets free. But first White will take advantage of Black's last move and win the Queen.

22.Re7+ Kg6 23.Qxd4 Rf8 24.Qxg4+ Kf6 25.Qe6+ Kg5 26.h4+ Kf4 27.Nd5+ Kg3 28.Qh3 checkmate

Do As I Say...


Readers are encouraged to enjoy the following quickie game, while recalling the charge: Do as I say, not as I do...

perrypawnpusher - schachix

blitz, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Ke8 


When declining the Knight, usually Black's King retires to f8.


6.Qh5+


The Queen check was irresistible, but not best. I had been trying to get a Jerome Gambit all week, and this was my first opportunity.


The proper way to play this, as I should have remembered, is 6.Nxc6 when after 6...Qh4 (no examples in The Database) 7.d4 Qxe4+ 8.Qe2 Qxe2+ 9.Kxe2 Bb6 10.Nb4 Bxd4 11.Nd5 Kd8 the game would be equal.


For the record, 6.Nxc6 bxc6 was seen in Wall,B - Qwerty, Chess.com, 2010 (1-0, 9) and Wall,B - LFTN, FICS 2012 (1-0, 20) while 6...dxc6 was dispatched in Wall,B - Gebba, Chess.com, 2010 (1-0, 11).


6...g6


I had already pulled off 6...Ke7 7.Qf7+ Kd6 8.Qd5+ Ke7 9.Nxc6+ Kf6 10.Qf5 checkmate, Kennedy - WeakDelphi, blitz 2 12, 2008 and 6...Kf8 7.Qf7 checkmate, perrypawnpusher - platel, blitz, FICS, 2011 (which probably influenced my choice of 6.Qh5+). 


7.Nxg6 


7...Qf6 


Here is where my opponent lost his chance. Houdini recommends 7...Bxf2+ 8.Kxf2 Nf6 9.Qh4 Rg8 10.Rf1 Rxg6 11.Kg1 Qe7 with advantage to Black.


Only 5 games in The Database have Black's counter-sacrifice of the Bishop, and 4 of them are wins for White, for example 7...Bxf2+ 8.Kxf2 Qf6+ (8...Nf6 was correct) 9.Nf4+ Kd8 10.d3 d6 11.Rf1 Qd4+ 12.Be3 Qf6 13.c3 Black resigned, Hultgren,R - Harrow, Campbell, CA 1960.


8.Nxh8+ Kd8 9.Qxc5 Qxh8 10.Qf8 checkmate
