Another RHP Jerome Gambit Tournament - Game 2


If there is a theme song for the Jerome Gambit, it would have to be "I Get By With A Little Help From My Friends Opponents". One way of looking at the following game is that White did not get enough support to win.

musirapha (1874) - jankrb (2055) 
Giuoco Piano Jerome Gambit tournament, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.d4 



White goes all in. For an extra pawn he gets more open, attacking lines. I was surprised to find only 10 games with this move in The Database.

7...Bxd4 8.f4

Instead, 8.Qf5+ was tried in Philidor 1792 - guest2187, www.bereg.ru 2013 (1-0,17); 8.c3 was seen in stampyshortlegs - GladtoMateYou, JGTourney4, ChessWorld 2009 (1-0, 12); 
8.Bg5 was played in bhargavs - ehvmc, FICS, 2009 (0-1, 30); and
8.0-0 appeared in santaklaus - Wesson, FICS, 2006 (0-1, 33). 

8...Nc6 9.c3 Bb6 

Although Black's King looks ill at ease, he has an extra two pieces to comfort himself with. White is not able to make progress.

10.Qd5+ Ke7 11.f5 Ke8 12.h4 Nf6 13.Qc4 Qe7 14.Nd2 d5 15.Qb5 Bxf5 16.c4 Nxe4 White resigned.

Another RHP Jerome Gambit Tournament - Game 1



Instead of grabbing the second sacrificed piece, Black plays a defensive system - but he plays it too defensively. Hanging on to material, instead of returning it at the right moment, can spell disaster, even (especially) against the Jerome Gambit.

jankrb (2055) - musirpha (1874)
Giuoco Piano Jerome Gambit tournament, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Kf8 


6.Nxc6 


Experimental are 6.Nd3, from Wall,B - Tim93612, Chess.com 2010 (1-0, 36) and 6.0-0 from billwall - DeDrijver, Chess.com, 2012 (1-0, 20).


Instead, 6.Qh5 is the rowdy Banks Variation, from Banks,P - Rees,M, Halesowen v Lucas BS, 2003 (1-0, 45). It is interesting to compare this line with the Paulsen Variation, where Black has placed his King on e7, instead of f8, e.g. the recently-discussed jankrb - Red House, Giuoco Piano Jerome Gambit tournament, RedHotPawn, 2013.


6...bxc6 


As noted as recently as in the game jankrb - Red House, Giuoco Piano Jerome Gambit tournament, RedHotPawn, 2013, the preferred capture is 6...dxc6, preventing 7.d4. The Database has many examples.

7.d4 Be7


A bit better was 7...Bb6 as in perrypawnpusher - hdig, blitz, FICS, 2007 (1-0, 17) and perrypawnpusher - mika76, GameKnot.com, 2008 (1-0, 17). 


8.Qf3+ 


Certainly an improvment over 8.f4 of perrypawnpusher - badhorsey, blitz, FICS, 2011 (1-0, 26). 


8...Ke8 9.0-0 d6 10.c4 Nf6 11.e5 dxe5 12.dxe5 Ng8





This retreat spells trouble.

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

Another RHP Jerome Gambit Tournament - Game 1


The following game, from a Jerome Gambit thematic tournament at RedHotPawn.com played last year, shows that complicated postions can arise that can challenge both players. In turn, the Queens, then the Kings, face grave danger.

musirapha (1874) - ZorroTheFox (1447)
Giuoco Piano Jerome Gambit tournament, RedHotPawn, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qxc5 d6 8.Qc3 

More frequently played is 8.Qe3.

8...Be6 9.d4 Bd7 10.Qb3+ Kf8 11.f4


11.0-0 was safer. If White was looking for trouble, he could always have played 11.Qxb7!? but he would have risked having his Queen offside for a while.

11...Qh4+ 12.g3 Qh3 13.Qxb7 Rc8


The Rook is probably better placed on the e-file, after which Black should continue his infiltration of the Kingside, as Houdini suggests, 13...Re8 14.Nc3 Qg2 15.Rf1 Bh3 16.Qb5 Qxh2 17.Qe2 Qxe2+ 18.Kxe2 Bxf1+ 19.Kxf1. 

14.e5 N8e7 15.Qf3 h6 

With 5 pieces developed to White's 1, Black does not need to play such a timid move, especially when he had available the useful 15...Bc6. Sometimes the Jerome Gambit can intimidate, however.

16.Nc3 d5 17.Be3 Nf5 18.Kf2

An alternative to consider was 18.0-0-0

18...c6 19.Na4 Nxe3 20.Kxe3 Bg4 21.Qf2 Ke7


22.Nc5 Rhe8

Here both players overlook that 22...Nxf4 23.Qxf4 Rhf8 would trap the White Queen. 

23.Raf1 Kf8 24.f5 Ne7

25.f6

This move is okay but, instead, 25.Ne6+ Kg8 26.Nf4 would trap the Black Queen. 

25...Nf5+ 26.Kd2 gxf6 27.Qf4 Qg2+ 



Black is thinking about the wrong King, as his own monarch requires attention (protection).

28.Kc3

This escape works in the game, but Houdini points out that the strongest idea was to sacrifice the exchange with 28.Rf2 Qxh1 29.Qxg4 when White's attack will be the one to crash through, e.g. 29...Ng7 30.Nd7+ Kf7 31.Nxf6. A Rook up, Black is helpless. 

28...Qe2 29.b3 Ne3

It is hard to believe at first (or second) glance, but the computer suggests that Black can survive with the cheeky 29...fxe5, giving the following hearty battle: 30.Qxh6+ Kg8 31.Qg6+ Ng7 32.Rf7 exd4+ 33.Kb2 Qe5 34.Re1 Bh5 35.Qh6 Bxf7 36.Rxe5 Rxe5 when it assesses that White's pawns help his Queen balance out play against Black's Rook, Bishop and Knight, e.g. 37.Nd7 Re2 38.Nf6+ Kf8 39.Qh8+ Ke7 40.Qxc8 Kxf6 41.Qxc6+ Ne6 42.Qxd5 Rxh2 43.g4 Rf2 44.b4. 

Now White can defend his King (with an exchange sacrifice) and get back to his attack.

30.Rf2 Nd1+ 31.Rxd1 Qxd1 32.Qxf6+ Kg8 33.Qg6+ Kh8 34.Rf7 Qa1+ 35.Kb4 Qxd4+ 36.c4 Qd2+ 37.Ka3 Qa5+ 38.Na4 Black resigned

Another RHP Jerome Gambit Tournament - Game 3



The following game is in some ways the opposite of the previous one. The game slides down the slippery slope from move 4, toward a Black win. White misses a chance to complicate the game, and perhaps take the advantage, at move 21. The game then continues to slide slowly toward the "inevitable" "0-1".

deriver69 (1401) - musirapha (1874)
Giuoco Piano Jerome Gambit tournament, RedHotPawn, 2014

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qe3 Nf6


Over 300 games in The Database reach this position, with White scoring 46%.

9.O-O Re8 10.d3 Kg8 11.Nc3 c6 12.f4 Qb6 13.Qxb6 axb6


The game has gone its own way, with Black wisely castling-by-hand and White delaying the advance of his "Jerome pawns" until after the Queens have been exchanged.

14.Be3 Bd7 15.f5 Ne5 16.Bxb6 Ra6 17.Bf2 c5 18.Be3 Neg4 19.Bf4 b5 20.Ne2 Bxf5


The position is a bit more complicated than either player appreciates.

White realizes that 21.exf5 Rxe2 would be clearly to Black's advantage, so he moves his Knight to a safer square; but in doing so he misses a chance to mix it up.

Challenging is 21.h3!? as now Black's Bishop is in an uncomfortable position, e.g. 21...Ne5 22.Bxe5 or 21... Nh6 22. Bxh6 in each case followed (if Black recaptures) by 23.Rxf5 with an edge for White.

It looks like after 21. h3!? White has an edge after 21...d5 (or 21...Bxe4 22. dxe4 Ne5) 22.hxg4 Bxg4
