Jerome Gambit: No Mercy

In some amateur sports leagues a game will be ended under the "mercy rule" if one team is significantly ahead of its opponent (i.e. unlikely to lose under normal circumstances). Such is not the case in chess - you can have a better position on the board for 18 moves, say, and resign after the 19th. As in the following game.

Wall, Bill - Guest757810
PlayChess.com, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.Nc3 Nf6 9.Bd2


There are 4 previous games in The Database with this move. White scored 0%. To be fair, all of the Jerome Gambiteers were playing higher-rated opponents.

9...c5

10.Qe3 Rf8 11.O-O-O Nc4 12.Qd3 Nxd2 13.Rxd2 Kg8


Black has castled-by-hand and has a piece for a pawn. If he keeps on making good moves, he will collect the full point.

14.e5 Ng4 15.exd6 Nxf2 16.Qd5+ Kh8 17.Re1 Bd7


Black has to keep his eye on White's pawn at d6, but with an extra piece for a pawn, he is doing well. Still, it is a complicated position. How should he continue?

18.Re7 Rf5 

Protecting the pawn at c5 and attacking the enemy Queen.

19.Qxb7 Black resigned


Wow! Black's Bishop is threatened, and the only square that even looks "safe" allows White's pawn to advance, 19...Be8 20.d7 Bf7 21.Qxa8!? Qxa8 22.d8/Q+ Qxd8 23.Rxd8+ Bg8 24.Ree8 - not so safe for the Bishop after all.

Best for Black seems to be giving up the Bishop for some play, 19...Qf8 20.Qxd7 Ng4, but after 21.Qe6 White will have centralized pieces and a couple of extra pawns, especially the dangerous on at d6.

Jerome Gambit: Past is Prologue

Here is a game from the first round of the Jerome Gambit tournament at RedHotPawn.com. Both White and Black clearly have a grasp of the opening, and the battle is an entertaining one. The outcome is an indication of how the second round - and the tournament - will turn out. 

SeinfeldFan91 - ZorroTheFox

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

7.O-O Ng4 8.h3 Bd6 9.e5 Be7 



Recommended,but there are no other examples in The Database.

Alternatively:

9...Nxe5 Giving the piece back is "scientific" but leads to an equal game according to Stockfish 7. 10.dxe5 Bxe5 11.Qd5+ (11.f4 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.f8=Q+ Rxf8 29.Qxf8 checkmate, Darthnik - aufdermaur, FICS, 2011) 11...Kf6 (11...Kf8 12.Qxe5 d6 13.Bg5 Qxf2+ 14.Rxf2+ Black resigned, ndrwgn - balahap, FICS, 2013) 12.Re1 d6 13.Rxe5 dxe5 14.Qd8+ Ne7 15.Qxh8 Qe4 16.Qf8+ Ke6 17.Bg5 Qb4 18.Qxg7 Bd7 19.Qf6+ Kd5 20.Nc3+ Kc4 21.b3+ Kxc3 22.Qxe5+ Qd4 23.Bd2+ Kxd2 24.Qxd4+ Kxc2 25.Rd1 Black resigned, Wall,B - Anonymous, lichess.org, 2016; or

10.hxg4 Nh6

Reasonable and straight-forward, especially since White's response "forces" Black to make a move he wants to make, anyhow; but 10...d6 was deeper and better. 

11.g5 Ng4  

Of course. Still, taking the g-pawn was better, as now the game has equalized - although that may not be apparent at first glance. 

12.Qf3+ Ke8 13.Qh3 Bxg5 14.Bxg5 Qxg5 15.Nc3 d5



15...h5!? was a thematic alternative. 

16.f4 Qg6

Thinking "attack" when "defense" was better attended to by 16...Qd8. 

17.Nxd5 Kd7 18.f5 Qg5 19.e6+ Kc6 



The alternative 19...Ke8 20.Rae1 is pretty bad for Black, but everything else leads to mate. 

20.Qc3+ Kxd5 21.Qc5+ Ke4 22.Rae1+ Ne3 23.Qe5 checkmate

Jerome Gambit: Chaos Rules

I enjoy playhing over the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games of ZahariSokolov playing at FICS. He shows an understanding of the opening, and brings a creativity that expands its impact.

In the following very difficult, complicated game, however, his opponent presents an odd, rarely-played defense, and the game quickly leaves recommended play. Still, it takes oversights on both sides before the winner is finally decided.

ZahariSokolov - mmamaju
standard, FICS, 2015

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



4...Kxf7 5.Nxe5+ Ke7



Here we have the "Jerome Gambit, Paulsen Variation", otherwise known as "An Odd Line in an Odd Line". It is more of a psychological ploy than a solid defense - but, in this game at least, it is successful.

6.Nc4 

Electing to retain his Knight. In similar situations (see below) it can be exchanged to double Black's pawns.

6.Qh5 is the strongest response, although there are not many examples in The Database: 6...Qf8 (6...d6 7.Qf7# stivb_99 - spymaster, GameKnot.com, 2008) 7.Nxc6+ (7.0–0 d6 8.Ng6+ hxg6 9.Qxh8 Nd4 10.Na3 Ne2+ 11.Kh1 Be6 12.d4 Bxd4 13.f4 Qf6 14.Nb5 Bb6 15.Bd2 a6 16.Nc3 Nxc3 17.Bxc3 Bd4 18.e5 dxe5 19.fxe5 Qxe5 20.Bxd4 Qxd4 21.c3 Qe5 22.Rae1 Qd5 23.Qxg7+ Kd6 24.Rd1 Qxd1 25.Rxd1+ Kc6 26.Qxg6 Black resigned, guest1200 – satmonger, Internet ChessClub, 2001) 7...dxc6 8.Qxc5+ Ke8 9.Qxf8+ Kxf8 10.c3 Nf6 11.d3 Kf7 12.0–0 Rf8 13.f4 Kg8 14.f5 Bd7 15.h3 Rae8 16.g4 h6 17.Bf4 Rc8 18.Nd2 c5 19.Nf3 c6 20.Nh4 Rf7 21.c4 Rd8 22.Ng6 Be8 23.Rf3 Rfd7 24.Ne5 Re7 25.Rd1 Nd7 26.Nxd7 Rexd7 27.Kf2 Bf7 28.Ke3 Kf8 29.h4 Ke7 30.g5 hxg5 31.hxg5 Ke8 32.g6 Bg8 33.Rh3 Kf8 34.Rh8 b5 35.b3 a5 36.Rdh1 Rxd3+ 37.Ke2 R3d7 38.Bg5 Re8 39.Ke3 bxc4 40.bxc4 Rd4 41.R8h4 Rxc4 42.Rb1 Rb4 43.Rxb4 cxb4 44.Kd3 Rc8 45.e5 Rd8+ 46.Kc2 Rc8 47.f6 c5 48.f7 Bxf7 49.gxf7 Kxf7 50.Rc4 Ke6 51.Bf4 Kd5 52.Kb3 a4+ 53.Kxa4 Kxc4 54.e6 Re8 55.Ka5 Rxe6 56.Bc7 Kc3 57.Bb6 c4 58.Bc5 Re5 59.Kb5 b3 60.axb3 cxb3 61.Kc6 Rxc5+ 62.Kxc5 b2 63.Kd5 b1Q 64.Ke6 Qb5 65.Kf7 Kd4 66.Kxg7 Qc6 67.Kf7 Ke5 68.Kf8 Qd7 69.Kg8 Kf6 70.Kh8 Qg7 checkmate, UNPREDICTABLE - aladu, FICS, 2009.

6...Ne5

Black's best response is 6...d5, which would be a TN, keeping his advantage.

7.d3

White should simply take the Knight on e5 and be better. With the text, he returns the advantage to his adversary.

One wonders if one of Alekhine's cats jumped on White's keyboard. 

7...Nxc4 8.dxc4 h6 9.Nc3 c6 10.Qg4 Qf8 11.O-O Kd8 12.Be3 Be7 13.e5 d6 14.Qh5 

14...Kc7 15.exd6+ Bxd6 16.Ne4

A slip. Better was 16.c5 Be7 17.Qd5+. 

16...Nf6 17.Qf3 Bg4 18.Qf4



Perhaps Stockfish 7's suggestion held out more hope: 18.Bf4 Bxf3 19.Bxd6+ Qxd6 20.Nxd6 Kxd6 21.gxf3

18...Bxf4 19.Bxf4+ Kc8 20.Nd6+ Kd7 21.Nxb7 Be2 22.Rfe1 Bxc4 23.Rad1+ Bd5 24.c4 Kc8 25.Nd6+ Kd7 26.cxd5 Nxd5 27.Bg3 

White has been fighting back fiercely since losing his Queen, and he is helped by Black's next move, which actually gives the attacker the advantage in the game. Perhaps time problems?

27...Re8 28.Ne4

A missed opportunity for White, as he had 28.Rxe8 Qxe8 29.Nxe8 Rxe8 with a small advantage.

Black is now able to move on to victory. 

28...Re6 29.f3 h5 30.Rc1 Rg6 31.Nc5+ Kc8 32.Ne6 Qb4 33.Rb1 Qb6+ 34.Bf2 Qa6 35.a3 Re8 36.Nc5 Rxe1+ 37.Rxe1 Qc4 38.Ne4 Qb3 39.Nc3 Nxc3 40.bxc3 Qxc3 41.Re8+ Kd7 42.Re1 Qxa3 43.Bh4 Qb4 44.Kh1 Qxh4 White resigned

Sang Froid


The ongoing RedHotPawn.com Jerome Gambit tournament continues to produce interesting and educational games.

Be sure to follow the games in the notes, too, for extra excitment!


golddog2 - deriver69
Giuoco Piano Jerome Gambit Tournament
RedHotPawn.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 7.Nc3 



Sang froid. White answers Black's wild counter-attack (which leaves two pieces en prise; see "A Pie-in-the-Face Variation") with a rare, but simple developing move. Anything is worth a try in such a precarious position.

For the adventurer with White, despite what a computer player might say about the position, it is reassuring to know that in 222 games in The Database, White scored a scintillating 67%!

7...Bb4

Instead, 7...Nd3+ was the odd idea of the coputer Milobot, in a crazy game that veered all over the place: 8.cxd3 (8.Qxd3) 8...Bf8 (8...Bxd4) 9.Qf3+ (9.Qb3+ or 9.O-O) 9...Qf6 10.Qh5+ Qg6 11.Qd5+ Ke8 12.O-O a6 13.f3 Ra7 14.Bf4 b5 15.Bxc7 Nh6 (15...Rxc7 16.Qe5+ Kd8) 16.f4 Qf7 (16...Rxc7) 17.Rae1 (17. Qe5+) 17...Qg6 (17...Rxc7) 18.f5 Qg4 $18 19.Qe5+ Be7 20.Bd6 Qxg2+ 21.Kxg2 Kf8 22.Qxe7+ Kg8 23.Qf8 checkmate, LeoJustino - MiloBot, FICS, 2012. Wow.

7...Ng4, like the text in the game, also preserves Black's advantage 8.Qf3+ (8.g3 Qf6 9.Qxg4 Bxd4 10.Nd5 Qxf2+ 11.Kd1 d6 12.Qh5+ g6 13.Qh4 Qf3+ 14.Kd2 Qxh1 15.c3 Qg2+ 16.Kd3 Be5 17.Bh6 Qh3 18.Qd8 Qxh6 19.Qxc7+ Ke8 20.Rf1 Qg7 21.Qc4 Be6 22.Nc7+ Kd7 23.Qxe6+ Kxc7 24.

8.dxe5 

The wildness continued after 8.O-O with 8...Ng4 9.h3 h5 10.Qf3+ Qf6 11.hxg4 hxg4 12.Qxg4 Bxc3 13.bxc3 Qh4 14.Qf5+ Nf6 15.f3 d6 16.Qf4 Qxf4 17.Bxf4 b6 18.e5 Nd5 19.Bd2 Ba6 20.Rf2 dxe5 21.dxe5 Rae8 22.f4 g6 23.Re1 Ke6 24.g4 Rhf8 25.Kg2 Ne7 26.Kg3 Bb7 27.c4 c5 28.Bc3 Ba6 29.Re4 Rd8 30 a4 Rd1 31.Rh2 Rg1+ 32.Kf3 Bb7 33.Ke3 Rxg4 34.Rf2 Black forfeited on time in a winning position,  PLURkidIT - CEZRUN, FICS, 2007.

8...Bxc3+ 9.bxc3 Qxe4+ 10.Qe2 Qxe2+ 11.Kxe2 Ne7 



A lot of the tension has been taken out of the position, and with only a pawn for his sacrificed piece, White needs to find a way to make use of his open lines and Black's slightly unsafe King.

This time, he is not successful.

12.c4 b6 13.g4 Bb7 14.f3 Rae8 15.Bb2 Ng6 



16.Kf2 Nxe5 17.Bxe5 Rxe5 18.Rad1 d6 19.Rd3 Rhe8 20.Rf1 Re2+ 21.Kg3 Rxc2 22.Rd4 Ree2 23.h3 g5 24.f4 Re3+ 25.Rf3 Rxf3 checkmate

"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+

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

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.

But what is chess...?

There is a fine line in chess between "chaos" and "complications" – and the Jerome Gambit and its relations, in this case, the Blackburne Shilling Jerome Gambit – tend to trample all over that line, especially in blitz chess.

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


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Ke7 5.Nxe5

Needlessly complicating the position – but what is chess without complications?

5...d6

An earlier battle between the two players continued 5...Nf6 6.c3 d6 7.cxd4 dxe5 8.Qb3 Nxe4 9.0-0 Qxd4 10.Qf3 Nxd2 11.Bxd2 Bg4 12.Bg5+ Kd7 13.Qxb7 Rc8 14.Qb5+ c6 15.Qb7+ Rc7 16.Qb8 Rc8 17.Qb3 Bc5 18.Be3 Qd6 19.f3 Bxe3+ 20.Kh1 Be6 21.Bxe6+ Qxe6 22.Rd1+ Ke7 23.Qxe3 Black resigned, crokit - sahistonline, FICS, 2011.

6.Qh5

Letting slip the thread of the game. Earlier in the year Black faced the stronger 6.Bxg8 (good at move 5 as well):  6...Rxg8 7.c3 (7.Nd3 Ke8 8.Qh5+ g6 9.Qd5 Nxc2+ 10.Kf1 Rg7 11.Nf4 Re7 12.d3 Nxa1 13.Qc4 a6 14.b3 Bd7 15.Bb2 Nxb3 16.Qxb3 Bc6 17.Bf6 Qd7 18.Bxe7 Qxe7 19.Ne6 Kd7 20.Nf4 Bh6 21.g3 g5 22.Nd5 Qe6 23.Kg2 Rf8 24.Nd2 Qf7 25.Rf1 Bb5 26.a4 Bc6 27.Qc4 g4 28.Qc1 Bxd5 29.exd5 Qxd5+ 30.Kg1 Qxd3 31.Rd1 Qd4 White resigned, Doctoroldhead - sahistonline, FICS, 2011) 7...dxe5 8.d3 Ne6 9.Qh5 h6 10.0-0 g6 11.Qe2 Ke8 12.Be3 Qd6 13.Nd2 b6 14.Nc4 Qd8 15.Nxe5 Bd6 16.Nc4 Be7 17.d4 Bg5 18.f4 Bh4 19.b4 Bb7 20.d5 Ng7 21.Ne5 Nh5 22.Nf3 Be7 23.Ne5 Bf6 24.Nxg6 Ng3 25.hxg3 Bxc3 26.Rac1 Bxb4 27.Qh5 Qd7 28.Ne5+ Black forfeited on time, Darthnik - sahistonline, FICS, 2011.

6...Nxc2+ 7.Ke2

Probably best was 7.Kd1, as after 7...Nf6 8.Ng6+ hxg6 9.Qxh8 Nxh8 Black does not have as great an advantage as after the text.

7...Nf6 8.Ng6+ Kxf7 9.Nxh8+ Ke7


Snatching defeat out of the jaws of victory. (...Kg8 looked safe enough)

10.Qf7 checkmate

Something To Watch Out For


It is so much easier in a scary movie: you know that you are moving into danger when the background music becomes ominous, perhaps the screeching of violins...

In a chess game, especially when playing a dubious opening like the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) it is important to be aware of dangerous themes.

Darthnik - spenjch
blitz, FICS, 2011

1.e4 e5 2.Bc4 Nc6 3.Nf3 Bc5


Already we have some foreshadowing with 3...h6 4.d4 exd4 5.Bxf7+ Kxf7 6.e5 Qe8 7.Qd3 Nxe5 8.Qxd4 Nxf3+ 9.Kf1 Nxd4 White resigned, Benschatko - Lakritzl, FICS, 2006; and


3...Nf6 4.Nc3 Bc5 5.Bxf7+ Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6 9.Bg5 h6 10.Bxf6 Qxf6 11.Nd5 Nf3+ White resigned, gjtlsdnr - silvalgo, FICS 2011.

4.Bxf7+


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6

 Even here, the danger begins to appear: 7...d6 8.f4 Qh4+ 9.g3 Nf3+ White resigned, Cradle - Foom, FICS, 2008 and Bevs - LordLucika, FICS, 2009.

8.f4 Qh4+

Or simply 8...Nf3+ White resigned, as in ainafets - Papaflesas, FICS, 2007 and stemplarv - KIAUA, FICS, 2007; or further 9.gxf3 Qxd4 White resigned, yorgos - Kompete, FICS, 2009.

9.g3 Nf3+ White resigned




Danger is everywhere, and we must learn to recognize it.

Yet Another Day in the Life of the Jerome Gambit


Sometimes it is fun to go easy on the analytics, and simply play through a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game. It is usually a roller coaster ride, with lots of thrills and chills for both players.

 



Darthnik - GregOakPark
blitz, FICS, 2011


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


4...Kxf7 5.Nxe5+ Nxe5 6.f4


Wow.

This "TN" (no examples in The Database) says "Yes, I know that I just sacrificed two pieces, but I still want to play the game my way, starting with the 'Jerome pawns'."

As they say, "no guts, no glory."

6...Ng6 7.d4 Bb6 8.e5 Qh4+


Black is skeptical, an attitude all defenders should have when facing the Jerome Gambit.

9.g3 Qh3 10.Be3 N8e7 11.Qd2 Nd5 12.Bf2 Qg2


Tough times for the gambiteer! As they also say, though, "It ain't over 'till it's over!" (especially in blitz).

13.Rg1 Qxh2 14.Nc3 Rf8

Preparing to castle-by-hand. Does Black overlook the loss of a piece here, or is he unconcerned? Oddly enough, the King never quite does get "castled".

15.Nxd5 c6 16.Ne3 Re8 17.0-0-0 d5


Black's difficulties continue. This center pawn strike manages to both activate White's "Jerome pawns" and overlook the threat to his Queen.

18.Rh1 Qxh1 19.Rxh1 Nf8 20.f5 g6


21.fxg6+

Blowing up Black's King's shelter. Both 21.e6+ and 21.g4 were playable as well. Go, Jerome pawns!

21...hxg6 22.c3 Bf5 23.Nxf5 gxf5 24.Qf4 Ke6


25.Rh6+ Kd7 26.Qxf5+ Kc7 27.Be3 Rad8 28.Bf4 Kb8


29.e6+ Bc7 30.Bg5 Rd6  31.Qf7 Rdxe6 32.Rxe6 Nxe6 33.Qxe8+ Bd8 34.Bxd8 a6 35.Qxe6 Ka7 36.g4 Black resigned


Cool. Now we have some idea why Darthnik sticks with the Jerome Gambit!
