Jerome Gambit: Explosive

Image result for clipart brain exploding

I recently received two Jerome Gambit games from chessfriend shugart, who plays at FICS. We have seen his games here before

His willingness to play at lightning time control continues to explode my brain.

One thing that helps in his play is familiarity with the opening, as the notes to the following game will show. (There might even be the chance that he reads this blog, and has picked up a tip or two.)

shugart - NightEagle
lightning, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4



The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7

In what appears to be a quick blitz game, shugart easily dealt with his opponent declining the gift: 4...Ke7 5.Nxd4 exd4 6.Bxg8 Rxg8 7.c3 d3 8.Qf3 h6 9.Qxd3 d6 10.O-O Be6 11.Qe2 Qe8 12.d4 Kd7 13.Qb5+ Kc8 14.Qxe8 checkmate, shugart - snob, blitz, FICS, 2013.

5.Nxe5+

The alternative 5.Nxd4 is a hybrid line that has also been played by Jerome Gambiteers such as drumme, HauntedKnight, JKELSEY and Wall:  5...exd4 6.Qh5+ g6 7.Qd5+ Ke8 8.Qe5+ Ne7 9.Qxh8 d6 10.Qxh7 Qd7 11.O-O Qg4 12.f3 Qg5 13.d3 Qf6 14.Nd2 Be6 15.Nb3 Bg8 16.Qh3 Be6 17.Qg3 Kd7 18.Bg5 Qf7 19.Bxe7 Bxe7 20.Nd2 Rh8 21.Rae1?! Bh4 22.Qf4? Qxf4 23.e5 Bxe1 (23...Qxh2+!) 24.Rxe1 Qxh2+ 25.Kf2 Qh4+ 26.Kg1 dxe5 White resigned, shugart -Yaman, lightning, FICS, 2014.

5...Ke8

(5...Ke6 6.Qh5 Nxc2+ 7.Kd1 Nxa1 8.Qf7+ Kxe5 9.f4+ Kd6 10.e5+ Kc6 11.Nc3 b5 12.Qd5+ Kb6 13.Qxb5 checkmate shugart - Manoelo, blitz, FICS, 2013)

6.Qh5+ Ke7

Necessary was 6...g6, but shugart has some experience with that, too: 7.Nxg6 hxg6 (7...Nf6 8.Qe5+ Ne6 (8...Be7 9.Nxe7 Qxe7 (9...Nxc2+ 10.Kd1 Qxe7 11.Qxe7+ Kxe7 12.Kxc2 d6 13.d3 Be6 14.Nc3 c6 15.Bg5 Rhg8 16.Bxf6+ Kxf6 17.g3 Raf8 18.f4 Ke7 19.Rae1 Kd7 20.e5 dxe5 21.Rxe5 Bg4 22.Rhe1 Kc8 23.Ne4 h5 24.Nd6+ Kd7 25.Nxb7 Rf7 26.Nc5+ Kc7 27.Re7+ Rxe7 28.Rxe7+ Kb6 29.Ne4 Bf3 30.Kd2 h4 31.Ng5 Bd5 32.gxh4 Bxa2 33.h5 Rh8 34.Rh7 Rf8 35.Ke3 Re8+ 36.Kf3 Bd5+ 37.Kg3 Re2 38.Ne4 Rxb2 39.h6 Rb3 40.Nf2 a5 41.Re7 Bg8 42.h7 Bxh7 43.Rxh7 a4 44.Rh8 Kc5 45.Ra8 a3 46.h4 Kd4 47.h5 Ke3 48.h6 Rb7 49.Rxa3 Rh7 50.Rc3 Kd4 51.Rxc6 Black resigned, shugart - Sutarsa, blitz, FICS, 2013) 10.Qxd4 Nxe4 11.0–0 Rg8 12.d3 c5 13.Qxe4 Qxe4 14.dxe4 Black resigned, shugart - smarcek, blitz, FICS, 2014) 9.Nxh8 Qe7 10.0–0 Qg7 11.f4 Qxh8 12.f5 Bd6 13.Qc3 Nc5 14.e5 Nce4 15.Qd4 c5 16.Qe3 Bxe5 17.d3 Bd4 18.Qxd4 cxd4 19.dxe4 d6 20.Bg5 Bd7 21.Nd2 Qg7 22.h4 h6 23.Bf4 Nh5 24.Bxd6 Ng3 25.Rf3 Bc6 26.Re1 Kd7 27.e5 Rf8 28.f6 Rxf6 White forfeited on time, shugart -Yaman, lightning, FICS, 2014) 8.Qxh8 Ne7 9.Qxd4 c6 10.0–0 d6 11.d3 Bd7 12.Bg5 Qc7 13.f4 c5 14.Qc3 b5 15.Bxe7 Bxe7 16.Qh8+ Bf8 17.Qf6 Be7 18.Qxg6+ Kd8 19.Nc3 Be8 20.Qg4 b4 21.Nd5 Qd7 22.Qxd7+ Bxd7 23.Nxe7 Kxe7 24.h3 Rg8 25.Kh2 Bc6 26.g4 d5 27.e5 Ke6 28.Rae1 d4 29.f5+ Kd5 30.e6 Be8 31.f6 Rf8 32.f7 Bc6 33.e7 Rxf7 34.Rxf7 Kd6 35.e8Q Bxe8 36.Rxe8 Kc6 37.Rxa7 Kd5 38.Rb8 c4 39.Rxb4 cxd3 40.cxd3 Kc5 41.Rb8 Kd5 42.Rb3 Ke6 43.Raa3 Kd5 44.Kg3 Black forfeited on time, shugart - Yaman, lightning, FICS, 2014. 

7.Qf7+ Kd6 8.Qd5+

Okay, okay, hold on a minute...

8...Ke7 9.Qf7+

Acceptable, but unnecessarily time-consuming, is 9.Qxd4, e.g. 9...Nf6 10.O-O d6 11.Nc4 Be6 12.Ne3 Kf7 13.f4 Be7 14.f5 Bd7 15.Nd5 Re8 16.Nxf6 Bxf6 17.Qd5+ Kf8 18.d3 Bc6 19.Qb3 Bd4+ 20.Kh1 Qh4 21.Nd2 Bb6 22.Nf3 Qf6 23.Bd2 Rad8 24.Bg5 Qf7 25.Bxd8 Rxd8 26.Qxf7+ Kxf7 27.a4 a5 28.c3 Bd7 29.b4 axb4 30.cxb4 Be3 31.Ra2 Bc6 32.b5 Bd7 33.Re2 Bb6 34.e5 dxe5 35.Nxe5+ Kg8 36.Nxd7 Rxd7 37.Rd2 Rf7 38.d4 Rd7 39.d5 Rd6 40.g4 Kf7 41.h4 Kf6 42.Kg2 Kf7 43.Kg3 Bc5 44.Kf4 Bb6 45.Ke4 Ba5 46.Kf4 Bxd2+ 47.Kf3 Ba5 48.Rd1 Bb6 White forfeited on time, shugart - Yaman, lightning, FICS, 2015.

That's it.

"Reality" vs "the Book"


Working on the previous blog post, I noticed that the defender (counter-attacker) had played that variation a few years earlier. The game was interesting enough to share, especially since the defender seemed conversant in Jerome Gambit strategies.. Again, however, "reality" outplayed "the book".

iconsisonline - atizzle
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



7.O-O

This is stronger than 7.dxc5 of Sutarsa - atizzle, blitz, FICS, 2014 (1-0, 19).

7...Ng4 8.h3 Bd6 9.e5 Bxe5


Following Sorensen - NN, Denmark, 1888, pragmatically returning the extra piece for a pawn (or two). Alternatives:

9...Nxf2 10.Rxf2+ Nf6 11.Rf4 Qg3 12.Rf3 Qg6 13.exd6 cxd6 14.c3 b6 15.Qb3+ Ke7 16.Re3+ Kd8 17.Na3 Bb7 18.Re2 Nh5 19.Nb5 Ng3 20.Rf2 Ne4 21.Re2 Rf8 22.Be3 Ng3 23.Rd2 Qe4 24.Re1 Rf3 25.Bg5+ Black resigned, Darthballz - Leftang, blitz, FICS, 2011; and

9...Nxe5 10.dxe5 Bxe5 11.f4 (11.Qd5+ Kf8 12.Qxe5 d6 13.Bg5 Qxf2+ 14.Rxf2+ Black resigned, ndrwgn - balahap, standard, FICS, 2013) Bd6 12.Qd5+ Kf8 13.Nd2 Nf6 14.Qd3 b6 15.Ne4 Bb7 16.Nxd6 cxd6 17.Qxd6+ Kf7 18.Qd3 Rhe8 19.Bd2 Kg8 20.f5 Nh5 21.Bc3 Nf4 22.Qc4+ Kh8 23.Rxf4 Qh6 24.Rg4 Rg8 25.f6 g6 26.f7+ Rg7 27.Qb4 d5 28.f8Q+ Rxf8 29.Qxf8 checkmate, Darthnik - aufdermaur, blitz, FICS, 2011

Black's best defense seems to be 9... Be7 10.hxg4 d6

10.dxe5 N4h6

Sorensen's opponent tried 10...Nxe5, which is playable, if risky, after 11.Qd5+ Kf6. 

11.Nc3 Ne7 12.Re1 Rf8 



Again, Black shows his understanding of the "big issues" in the defense, as he prepares to castle-by-hand.

Unfortunately, the move allows his Queen to be trapped.

White follows up quickly.

13.Re4 Qxe4 14.Nxe4 Kg8 15.Bxh6 gxh6 16.Nf6+ Kh8 17.Qd3 Ng6 18.Qc3 c6 19.Nh5 Rf5 20.e6+ Ne5 21.e7 Black resigned

Keep Fighting


When you are new to playing the Jerome Gambit, you are bound to miss some of its "subtleties", as, most likely, will your opponent. The best advice, as with all gambits, is to "Keep fighting".

The player of the white pieces in the following game has only one Jerome in The Database. Yet his play could be a lesson to veterans of the opening.


Sutarsa - atizzle

blitz, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 


This move, as opposed to 6.Qh5+, was Alonzo Wheeler Jerome's preference when he started playing the opening.


The Database has 1,346 games with 6.d4; White scores 51%. By comparison, it has 3,520 games with 6.Qh5+; White scores 55%.


6...Qh4 


Black's move, a bold counter-gambit seen as early as 1888 in Sorensen - NN, Denmark, is what makes White's 6th move risky - although you will have to take my word for it.


The move shows up only 214 times in The Database (16% of the 6.d4 games) and White scores a misleading 68%.


On the other hand, in a blitz or club game, you might like your odds as White.


7.dxc5


This is a dangerous position for White. Best is 7.O-O


7...Qxe4+ 8.Be3 Nf6


Black's move is solid and good, but the consistent 8...Qxg2 is better. 


9.O-O Neg4 10.Nc3 Nxe3 11.fxe3 Qxe3+ 12.Kh1 Rf8 




Black has only one other game in The Database himself, from four years earlier, but he understands the necessity of safeguarding his King - here, by castling-by-hand.


White has to act fast. While behind in material, he can at least take small encouragement in his opponent's undeveloped Queenside.


13.Qd5+ Qe6 14.Qg5 Kg8 15.Rae1 Qc6




This simple "get out of the way of the Rook" move is the cause of Black's upcoming troubles. Instead, 15...h6 16.Qg6 Qf7 would help him consolidate.


16.Re7 Rf7


The alternative isn't much better: 16...Ne8 17.Rxf8+ Kxf8 18.Nd5 Qxc5 19.Rxe8+ Kxe8 20.Nf6+ gxf6 21.Qxc5.


17.Nd5 Qxd5


Black slides toward checkmate instead of surrendering his Queen. Instead, he could have tried 17...h6 18.Nxf6+ Qxf6 19.Rxf6 Rxe7 (19...hxg5 20.Re8+ Kh7 21.Rxf7) 20.Qd5+ Re6 21.Rxe6 dxe6 22.Qd8+ Kh7 23.Qxc7 or 17...Kf8 18.Rxf7+ Kxf7 19.Qh5+ Kf8 20.Nxf6 gxf6 21.Re1 Qe6 22.Rxe6 dxe6 with dreary prospects. Both lines are worth playing over to see the attack unfold.


18.Qxd5 Nxd5 19.Re8+ Black resigned.
