Another Example of the Vitzthum Attack


Earlier on this blog, I have looked at the Sarratt or Vitzthum Attack as a possible fore-runner to the Jerome Gambit. (See "A Bridge To... Somewhere?", "Another Distant Relative?", "The Sarratt Attack" and "Another look at the Sarratt Attack").

Recently I discovered a game published in the "Chess" column of the April 23, 1876 issue of  the St. Louis Globe - Democrat. I have changed the notation from descriptive to algebraic and added some diagrams. The comments remain those of the newpaper's chess editor.


Chess in St. Louis
A Rapid Skirmish, Recently Played At St. Louis Chess Club

Mr. H - Mr. M 
St. Louis Chess Club, 1876

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4



This was long the accepted move at this point, but now 4.Nxd4 is now more common.

4...Bc5 5.Ng5 Nh6 6.Nxf7 Nxf7 7.Bxf7+ Kxf7 8.Qh5+ g6 9.Qxc5



All "book" so far.

9...Rf8

9...d5 is the only correct move here, giving black the better game.

10.Bh6 Re8 11.Nd2 Kg8 12.Qd5+ Kh8 13.Qf7



White now wins by force, let black play as he will.

13...Rg8 14.Nf3 Qe8 15.Ng5 and wins

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

No Doc


Bill Wall is not a professional psychologist, but when it comes to playing off-beat chess openings, he understands a lot about how his opponents think. This can be of considerable help when playing the Jerome Gambit.

In some of the notes I give a number of complete Wall games that have been referred to in previous blog posts, but have never been presented in their entirety.

Wall, Bill - Guest2928386

9... h6 as in perrypawnpusher - caterwaul, blitz, FICS, 2010 (1-0, 39).

10.O-O

Bill takes a wait-and-see stance. Similar, but for comparison: 10.Be3 Bxe3 11.Qxe3 Kf7 12.h3 Be6 13.f4 c5 14.f5 Bd7 15.g4 Re8 16.O-O Bc6 17.Qf4 Qb6 18.b3 Rad8 19.Nd2 c4+ 20.Kh2 cxd3 21.Nc4 Qd4 22.cxd3 Qxd3 23.Rad1 Qc2+ 24.Rd2 Qc3 25.Nxd6+ Rxd6 26.Qxd6 Nxe4 27.Qc7+ Kg8 28.Rd8 Qg3+ 29.Kh1 Nf2 checkmate MrJoker - Macuta, Internet Chess Club, 2011. 

10...Bh5 11.h3 Qe7 12.Nc3 c6 13.a3 



Okay, Bill's got me puzzled - and I know something about the Jerome Gambit. How can he afford to play 11.h3 and 13.a3 when he is playing a gambit, and time is supposed to be of the essence?

As we will see, he accurately accesses his opponent as being unprepared or uncertain about the proper defense (although the light-squared Bishop is free and trying to protect the Kingside), so there is time for White to keep his options open.

Sometimes letting Black keep his options open can lead to him making errors.

13...Bg6 14.Bg5 Qe5 15.Bf4 Qe6 16.Na4 



If nothing else, Bill can eliminate his opponent's "two Bishops". 

16...Nh5 17.Nxc5 dxc5

Not 17...Nxg3 18.Nxe6+ Ke7 19.Bxg3 Kxe6 20.f4. 

18.Bd6+ Ke8 19.Qh2 


19...Kd7

Too casual. It is not clear that the King is safer in his new position, and the (doubled) pawn that he give up is certainly of worth.

20.Bxc5 b6 21.Bd4 Qf7 



Black's pieces are not so much developed as they are jumbled on the Kingside. His Bishop should have gone to f7 on his last move.

22.f4 Qe7 23.g4 Nf6 24.e5 Nd5

Bill points out that Knight retreats lead to trouble too: 24...Ng8 25.f5 Be8 26.f6 gxf6 27.exf6 Qf7 28.Rae1 or 24...Ne8 25.f5 Bf7 26.e6+

25.f5 Be8 26.c4 Nc7 27.b4



Those crazy pawns! All 8 of them.

It is important to mention that Stockfish 6 rates White about 1/2 pawn better in this position. If Black can remain calm, he should be able to hang on.

27...Rf8 28.e6+ Kc8 29.a4 Kb7 



Black has castled-by-hand, but his King still needs to be careful. I've got him right where he wants me! he might have thought, somewhat confusedly.

30.a5 Na6 31.b5 cxb5 
32.cxb5 Bxb5 33.Rfb1 Nc7 



Black's light-squared Bishop continues to defend valiantly with the Knight, but - those pawns...
34.axb6 axb6 35.Qg2+ Kc8

Black's situation has deteriorated to the point that only 35...Kb8 would save him from a forced checkmate.

36. Rxa8+ Nxa8 37.Qxa8+ Kc7 38.Be5+



Black resigned

The Old "Poisoned Rook" Trick Again


It can be fun for Black to play a game of "duelling Knights" in certain lines of the Blackburne Shilling Jerome Gambit - his Knight is busy on one side of the board while White's is busy on the other - but he has to be careful not to fall victim of a poisoned piece.

aguisou - Gomenovich
blitz, FICS, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ 



The Blackburne Shilling Jerome Gambit.

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

Interestingly, drumme - Gomenovich, blitz, FICS, 2014 continued 6.c3 Nc6  before the Queen check, 7.Qh5+ g6 8.Nxg6 Qf6 9.Nxh8+ Kd8 10.Nf7+ Ke7 11.d3 Qxf7 12.Bg5+ Nf6 13.Bxf6+ Qxf6 14.Qxh7+ Qg7 15.Qh4+ Ke8 16.0-0 Ne5 17.Nd2 Nxd3 18.Nf3 d6 19.e5 Qg4 20.Qh8 dxe5 21.Nxe5 Nxe5 22.Qxe5+ Be7 23.Rae1 Bd7 24.Qxe7 checkmate.

Kicking the Knight first didn't work in gregweb - Gomenovich, blitz, FICS, 2015 as Black had an effective counter 6.c3 d6 7.cxd4 dxe5 8.dxe5 Qe7 9.d4 Bd7 10.0-0 Nh6 11.Nc3 c5 12.Nd5 Qd8 13.Bxh6 gxh6 14.Nf6+ Kf7 15.Qh5+ Ke7 16.d5 Bg7 17.d6+ Kf8 18.e6 Bxe6 19.e5 Bxf6 20.exf6 Qxf6 21.Qxc5 Kf7 22.Qc7+ Kg6 23.Qxb7 Rhb8 24.Qe4+ Bf5 25.Qe7 Qxe7 26.dxe7 Re8 27.Rfe1 Kf7 28.Rac1 Rac8 29.Rcd1 Rxe7 30.Rxe7+ Kxe7 31.Rd5 Be6 32.Ra5 Rc7 33.Rh5 Rc1 checkmate.

aguisou has had some experience with 6.c3 as well, in a couple of games played a couple of months apart: 6...Qg5 7.cxd4 Qxg2 8.Qf3 Qg5 9.Qf7+ (here Black resigned in aLmaLja - aguisou, blitz, FICS, 2014Kd8 10.Qxf8 checkmate, aLmaLja - aguisou, blitz, FICS, 2014.

6...g6 7.Nxg6 Nxc2+ 

The pawn is digestible, but the Rook is poisoned. 

8.Kd1 Nxa1

A quick look at The Database shows 65 games with this position. White scores 82%. 

9.Nxh8+ Ke7

10.Qf7+ 

Or 10.Qe5 checkmate. perrypawnpusher - mbranimir, blitz, FICS, 2009. 

10...Kd6 11.e5+ 

Or 11.Qd5+ Ke7 12.Qe5 checkmate. Yes, I missed the mate, too, in perrypawnpusher - robertpthom, blitz, FICS, 2010 (1-0, 32).

White has his own ideas on how to win the game.

11...Kc6 12.Qc4+ Bc5 



There is danger everywhere: 12...Kb6 13.Nc3 (13.d3 Qg5 14.Bxg5 Black resigned, Handlangari - PlatinumKnight, FICS, 2005) 13...c5 14.Nf7 Qe7 15.Nd5+ Black resigned, GOH - Neca, FICS, 2008.

Lots of Practice, Some Theory


Today's blog is full of games relevant to our main one. There is a little bit of "theory" tossed in, too. Enjoy the efforts of steveod and PEITONER.

PEITONER - steveod
blitz, FICS, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 



The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit. Black may be hoping for 4.Nxe5?!, and he may be expecting 4.Nxd4, 4.c3, 4.d3 or 4.0-0; but now he has something new to think about.

In this case, over the last decade plus, steveod has played quite a few BSGs at FICS, faced quite a few BSJGs, and even played a few himself. I thought it would be interesting to share his experiences as they appear in The Database, positive and negative. His games provide a pretty good overview of the Blackburne Shilling Jerome Gambit.

Let me start by presenting a Jerome Gambit / Blackburne Shilling Jerome Gambit hybrid game: 4.Nc3 Bc5 5.Bxf7+ Kxf7 6.Nxe5+ Ke6 7.Qg4+ Kxe5 8.f4+ Kd6 9.e5+ Kc6 10.b4 d5 11.Qg3 Nxc2+ 12.Kd1 Nxa1 13.b5+ Kb6 14.Qd3 c6 15.Na4+ Kc7 16.Nxc5 b6 17.Na6+ Bxa6 18.bxa6 Ne7 19.Ba3 Ng6 20.Bd6+ Kc8 21.Qf5+ Qd7 22.Qg5 Re8 23.Rf1 Ne7 24.Qxg7 Nf5 25.g4 Nxg7 White resigned, crystalleaf - steveod, FICS, 2013

I have not promoted declining the gambit, in fact I have referred to it as intending some kind of "Jedi mind trick", but I note that steveod has played several games with 4...Ke7:

Database Asterisk


The previous blog post mentioned that a large percentage of the games in The Database is from the online website the Free Internet Chess Server (FICS). This is because that is the site where I am a member, have played most of my Jerome Gambit games, and have the greatest access to their games database.

I am always open to game contributions from Readers, and I would like nothing better than to be able to add 50,000 - or 5,000 - or 500 - or 50 - or 5 - Jerome Gambit (or related) games played on the Internet Chess Club (ICC) site, or GameKnot.com, or Chess.com , or wherever - or even (especially) over-the-board games played at your favorite chess club.

By the way, I have already received requests for a copy of The Database. I can send you a compressed (.zip) PGN file via email, at no cost - just ask.
