Blackburne Shilling Jerome Gambit: Creativity

I recently ran across an unusual line in the Blackburne Shilling Jerome Gambit that led to some interesting play - no doubt "enhanced" by the blitz time limit. White's creativity is to be applauded.

sahistonline - sriwijaya
5 5 blitz, FICS 2016

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




Blackburne Shilling Gambit.

4.Bxf7+

Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 



7.f4+

A rare, but interesting idea. Most recommended is 7.cxd4+ leading to an equal game.

7...Kxe4

Not 7...Kxf4 which gave White an immediate payoff after 8.Rf1+ (8.Qh5!?) Ke5 9.cxd4+ Kxd4?! 10.Qa4+ (10.Rf5!?) Ke5 11.d4+ Ke6 12.Qb3+ (12.d5!?) Kd6?! 13.Qd5+ Ke7 Black resigned, drakorg - borodin, FICS, 2002.

Best, as always in this line of the Blackburne Shilling Jerome Gambit, was to retreat the King, e.g. 7...Ke6.

8.d3+

White should not seek to immediately recover his sacrificed material, i.e. 8.cxd4 Kxd4 (8...Kxf4 leads to mate 9.Rf1+ Kg5 10.d3+ Kg6 11.Qg4+ Black resigned, jorgemlfranco - FoldZero, FICS, 2012; 8...d5!?) 9.O-O Bc5 10.Kh1 Qh4 11.Qa4+ Kd5 12.Nc3+ Kd6 13.d4 Bb6 14.Bd2 Nf6 15.Qb4+ Ke6 16.Rae1+ Kf7 17.Qc4+ Kg6 18.f5+ Kh5 19.Ne2 d5 20.Qd3 Ne4 21.Nf4+ Kg4 22.Qf3+ Kxf5 23.Ng6+ Kxg6 24.Qf7 checkmate, richiehill - steadylooking, FICS, 2011.

Best is to lock the enemy King in the center with 8.Qh5.

8...Kd5 9.Qh5+

The King is free. White might as well play 9.cxd4 and accept that he is worse.

But, remember, this is a blitz game!

9...Kc6 10.cxd4 Qe7+ 11.Kf2 Nf6 12.Qf3+ Nd5



In the BSJG, as well as in the Jerome Gambit, Black should always be concerned about blocking in his light-squared Bishop, which in turn blocks his Rook. Best, therefore, was 12...d5!?.

13.Nc3 Qd6 14.Be3 b6 15.Rac1 Kb7 16.Nxd5 c6 17.Nc3 



Black has castled-by-hand on the Queenside.

White's advantage isn't his extra, doubled pawn, it is his great lead in development.

17...g5 18.Rhf1 Be7

Black would have done better to stick with his original idea 18...gxf4 19.Qxf4 Qxf4+ 20.Bxf4 d5 and White has only an edge.

19.Nb5

More direct was opening the position with 19.d5!?

19...Qd5

How ironic: Black erred earlier by putting his Knight on this square, now he is mistaken putting his Queen there. Then as now, ...d5!? was the move with near equality. The locked up pieces will never become part of the game.

20.Qxd5 cxd5 21.fxg5 Rf8+ 22.Kg1 Rxf1+ 23.Kxf1 Bd8



24.Nd6+ Ka6 25.Nxc8 Rxc8 26.Rxc8 Black resigned

A High Level of Danger


The Blackburne Shilling Jerome Gambit frequently leads to positions with a high level of danger. 

For example, the Black Knight that has thematically leaped to d4 often goes on to c2, where sometimes it captures the White Rook at a1 with advantage; sometimes it captures the White Rook at a1 causing a disadvantage; and sometimes the White King walks over and captures it before it can get to a1.

Too, there are the lines where Black's King grabs material in the center of the board, then creeps away. Or not. 

jorgemlfranco - FoldZero
blitz, FICS, 2012

1.e4 e5 2.Bc4 Nc6 3.Nf3 Nd4 4.Bxf7+ 


The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 


7.f4+

Varying from the recommended 7.cxd4+, when Black then does best to head his King homeward with 7...Ke6 with a balanced game.

7...Kxe4

Grabbing material is not as wise as heading the King homeward with 7...Ke6.

An earlier game, featuring 7...Kxf4, illustrated similar dangers, although the play could have been improved in different places 8.Rf1+ (8.0-0+) 8...Ke5 9.cxd4+ Kxd4 (9...Ke6) 10.Qa4+ (10.Rf5) 10...Ke5 11.d4+ Ke6 12.Qb3+ Kd6 (12...d5) 13.Qd5+ Ke7 Black resigned, drakorg - borodin, FICS, 2002.

8.cxd4

Likewise, grabbing material. 

White could keep an edge by focusing on the enemy King, as Rybka suggests: 8.Qh5 Nc2+ 9.Kd1 g5 10.Qf3+ Kf5 11.fxg5+ Kg6 12.Rf1 Qe8 13.Kxc2 d6 when White's pawns and attack are adequate compensation for the sacrificed piece.

8...Kxf4 

More material = more risk. This is a complicated line!

Another uneven instructive tale: 8...Kxd4 9.0–0 Bc5 (9...Nf6) 10.Kh1 (10.Nc3) 10...Qh4 (10...Be7) 11.Qa4+ Kd5 12.Nc3+ Kd6 13.d4 (13.Qe4) 13...Bb6 14.Bd2 (14.Qb4+) 14...Nf6 (14...Ke6) 15.Qb4+ Ke6 (15...c5) 16.Rae1+ Kf7 17.Qc4+ (17.Qe7+) 17...Kg6 (17...Kf8) 18.f5+ Kh5 19.Ne2 d5 20.Qd3 Ne4 21.Nf4+ Kg4 22.Qf3+ Kxf5 23.Ng6+ Kxg6 24.Qf7 checkmate, richiehill - steadylooking, FICS, 2011

Rybka prefers 8...Nf6 9.0-0 Kf5.

9.Rf1+ Kg5 10.d3+ Kg6 11.Qg4+ Black resigned

More Devastation


Here is another recent game by aymmd, featuring a variation in an opening line that looks good, but turns out to be significantly different than the original, much to Black's dismay. More devastation.

aymmd - LochChessMonster
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nf6 3.Nc3 Nc6 4.Bc4 Bc5 5.Bxf7+


The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4


7...Nxe4

Black is up two pieces, and he finds a creative way to return one of them; but, as addressed in "Delayed Devastation", the strongest move here is 7...Bd6 (not 7...Bxd4). 

8.Nxe4 Bb4+

Other ideas: 8...d5 in HauntedKnight - astalaveesta, FICS, 2011 (1-0, 29); 8...Be7 in perrypawnpusher - sdockray, blitz, FICS, 2010 (1-0, 28); 8...Qh4 in perrypawnpusher - kfollstad, blitz, FICS, 2010 (1-0, 24); 8...Bb6 in perrypawnpusher - BallsOfFire, blitz, FICS, 2010 (1-0, 9); while 8...Bxd4 seems best as in yorgos - josephjorkens, FICS, 2009 (1-0, 45).

9.c3 Qh4

Black plays va banque... This position is oddly like the one in "Beyond Gloom and Doom" only White has a Knight, not a pawn. at e4. The difference favors White.

Previously seen was 9...d5 in perrypawnpusher - richiehill, blitz, FICS, 2010 (1-0, 19); but 9...Re8 or 9...Nc6 are probably better choices.

10.Ng5+ Kg6

I suppose this move was inspired by Black's wish to keep the 8th rank open so that he could place his Rook aggressively. However, he would have done better to try 10...Ke8, e.g. 11.cxb4 h6 12.g3 Qg4 13.dxe5 Qxd1+ 14.Kxd1 hxg5 15.Bxg5 and White has a lesser advantage. 

11.dxe5 Be7

Black saves his Bishop and attacks White's Knight a third time – but the house falls in on him.

12.Qc2+ Kh6 13.Nf3+ Kh5 14.Nxh4 Bxh4 15.Qf5+ g5 16.g4+ Kh6 17.Qf6 checkmate

More Updating



Following "Checking Back", it is time to use a recent Blackburne Shilling Jerome Gambit game to look at one of its more exciting variations.

 


pigsfeet - jantonacci
blitz, FICS, 2011

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


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+ Kxd4


Black's King has gone far afield to grab extra material. Why did he do that? Some chess players see the board as an all-you-can-eat buffet, and chow down on everything. Others might compare development, White vs Black, and as the first player has no pieces developed compared to the second player's one (the King) what appears to be the problem?

Safer was heading for home with 7...Ke6 as in richiehill - RVLY, FICS, 2009 (1-0,24).

8.d3

This is the recommended move, although White has also played 8.b3 (8.b4 is a variant) in jonyfin - jantonacci, FICS, 2009 (0-1, 16).

For 8.Nc3, see perrypawnpusher - PunisherABD, blitz, FICS, 2009 (1-0,14) and billwall - apollyon2010, Chess.com, 2010 (1-0,12).

DragonTail scored quickly with 8.Qc2 Qg5 9.Qc3+ Kxe4 10.0-0 Bd6 11.d3+ Kf5 12.Bxg5 Kxg5 13.Qxg7+ Black resigned, DragonTail - tcharge, FICS, 2009.

8.Qa4+ is an interesting idea which will be covered in a later post. 

8...Bb4+

Retreats such as 8...Ke5 in perrypawnpusher - PunisherABD, blitz, FICS, 2009 (1-0, 27) and 8...Nf6 9.Be3+ Ke5 from perrypawnpusher - RVLY, blitz, FICS, 2010 (1-0, 26) have been seen.

Best for Black seems to be 8...Kc5 with only a slight disadvantage.

9.Nc3

Playable also is 9.Kf1!? or 9.Ke2!? although the text is natural and even allows Black further gluttony, if he wishes.

9...d5

"Luft!" says the Queen.

Also played has been 9...Bxc3+ 10.bxc3+ when taking the c-pawn is fatal after 10...Kxc3 11.Qb3+ (The Database does not have any examples, but Edisce - nkm, FICS, 2005 came close with 11.0-0 Qf6 12.Be3 Kb4 13.Rb1+ Ka5 14.Qb3 c5 15.Qa3 checkmate).

perrypawnpusher-AdamRou, blitz, FICS, 2010 (1-0, 28) saw 9...Bxc3+ 10.bxc3+ Ke5 11.Qh5+ Ke6. 

10.Be3+

Again, a very reasonable move, although White may try to weave a mating net by putting his Queen on b3 and his Bishop on f4. Black might give up his Bishop to buy White off.

10...Ke5 11.Qh5+

The Queen must commit herself, as the enemy monarch is making his escape.

11...Kf6

Rybka 3 recommends 11...Kd6, when, if Black can survive the scary, pawnful middlegame, he can then take a few swipes at White and enter an endgame, down a pawn and the exchange: 12.Qxd5+ Ke7 13.Qg5+ Nf6 14.Qxg7+ Ke6 15.f4 Rg8 16.f5+ Kd6 17.Qf7 Bxc3+ 18.bxc3 b6 19.Bd4 Kc6 20.Qc4+ Kb7 21.Bxf6 Qxf6 22.Qxg8 Qxc3+ 23.Ke2 Qc2+ 24.Ke3 Qc5+ 25.Kf3 Bxf5 26.Qc4 Qxc4 27.dxc4 Be6.

In the game, Black gives up his Queen, and then his King.

Those who cannot remember the past...

According to George Santayana, "Those who cannot remember the past are condemned to repeat it."

Not everyone who plays the Blackburne Shilling Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4) has read the blog post here, "Clearly Unclear", so I should probably add "Those who do not know the past are likewise condemned to repeat it."

Pity. More points for the Jerome Gambit Gemeinde.

richiehill - XGrandMaster
blitz, FICS, 2010

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


4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Nc6


This is a very reasonable alternative to the line that goes 6...Kxe5 7.cxd4+. I used games played by GOH and SotoG to look into this line last year.

7.Qg4+

White can withdraw his Knight, 7.Nf3, with an even game; but the recommended move is 7.d4 with a poisoned pawn in the follow-up: 7...Nxe5 8.dxe5 Kxe5? 9.Qd5+ Kf6 10.Bg5+ Black resigned APe-Sali, blitz, FICS, 2009

7...Kxe5

Taking the piece is the right move (7...Ke7 is only even), but it must have unsettled Black to do so. After all, White is not throwing all of this material around just to bluff, is he?

8.d4+

8...Kf6 9.Bg5+ Black resigned

Ouch.

After 8...Kd6 9.e5+ Ke7 10.Bg5+ Nf6 11.0-0 Kf7 12.exf6 gxf6 Black's King would have still been uncomfortable, but he would have had an extra piece to console himself. I wonder where someone could have learned about that ?

Complications, Anyone?


You might not be a fan of the Blackburne Shilling Gambit, and you might not be a fan of the Jerome Gambit, but you would have to be a pretty jaded chess player not to appreciate the complications stirred up in the following game.

richiehill - fidotopdog
standard game, FICS, 2010

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


4.Bxf7+ Kxf7 5.Nxe5+ Ke6


6.c3 d6

Recently looked at on this blog: see perrypawnpusher - ozypawnstar, blitz, FICS, 2010.

7.Qg4+

Reviving and older line and introducing further complications.

7...Ke7

Capturing the Knight with 7...Kxe5 is only asking for trouble, although if Black has his wits about him he can still draw. 

White can split the point after that with 8.f4+ Kxe4 (8...Kf6 costs Black his queen after 9.Qh4+ Kf7 10.Qxd8 but he can limp on with a worse position after 10...Nc2+ 11.Kf2 Nxa1) 9.f5+ Kd5 (or 9...Ke5 10.cxd4+ and White is better; or 9...Kd3 10.Qxd4+ Kc2 11.Na3#) 10.Qxd4+ Kc6 11.Qc4+ Kd7 12.Qe6+ Kc6 13.Qc4+ draw by repetition, as White has nothing better.

White has tried for more after 7...Kxe5 with 8.cxd4+ and gotten lucky after both 8...Kf6 9.Qh4+ Kf7 (9...g5 was necessary to keep the game even) 10.Qxd8 Be7 11.Qxc7 Nf6 Black resigned, Jeopar - InduMMS, FICS, 2009;

and 8...Kxd4 9.Qe2 (9.Qf3 is unclear) 9...Nf6 10.d3 (better 10.Nc3 Ke5 11.f4+) 10...Ke5 11.f4+ Ke6 12.d4 Kf7 when Black was better, but White won in 26 moves in SynapticGap - osmann, FICS, 2006.

It is easy to see why fidotopdog retreated his King in this game!

8.Qg5+ Nf6

This looks natural, but Black would have done better exchanging Queens, i.e. 8...Ke8 9.Qxd8+ Kxd8. He probably avoided this line because of 10.Nf7+ Ke8 11.Nxh8, but his position would have been better after the reciprocal 11...Nc2+ 12.Kd1 Nxa1. That kind of thing is easier to see after the game.

9.cxd4 dxe5

10.Qxe5+

Choosing to win the Bishop rather than the Knight, but this takes some cooperation. Better was the straight-forward 10.dxe5, when 10...Qd3!? 11.exf6+ gxf6 12.Qf4 would give White the edge. 

10...Be6

Falling in with White's plan. Instead, 10...Kf7 leads to a position where Black has a piece for three pawns. richiehill might have been happy with that, but "objectively" Black would have been better. 

11.d5 Ng4

A panic-induced attack on the enemy Queen.

As often happens in the Jerome Gambit family of games, there comes a time for Black to return his extra piece for some pawns. After 11...Nxd5 12.exd5 Qxd5 White can try the scary-looking 13.Qxc7+ to go two pawns up, but 13...Kf6, preparing ...Bd6 (the power of the two Bishops), shows Black's better development to good advantage. After 14.Qf4+ Qf5 15.d4 Bb4+ 16.Nc3 Rac8 White's best might well be to return a pawn with 17.0-0 Bxc3 18.bxc3 Rxc3 when the impact of the first player's extra pawn may not be very much.

12.Qxe6 checkmate

Only Pieces of the Puzzle



If a chess game is like a puzzle, the following contest shows that my opponent and I could find only pieces of it, never quite putting together the full picture.


perrypawnpusher - richiehill
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5


The Italian Four Knights Game.

5.Bxf7+

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+

Last year my opponent tried his hand with this opening and scored quickly: 6.Ng5+ Ke7 7.d4 exd4 8.Nd5+ Nxd5 9.exd5 Kd6 10.Nf7+ Black resigned, richiehill - SullenKhan, FICS, 2009.

He also had a successful go with the Blackburne Shilling Jerome Gambit, richiehill - PlatinumKnight, FICS, 2009.

6...Nxe5 7.d4


7...Nxe4

An interesting defensive idea that I've looked at in "Nothing Much Happened" and "Navigating On One's Own".

Most often seen is 7...Bxd4 and best is 7...Bd6.


My opponent once tried 7...Bb4 8.dxe5 Nxe4 9.Qd5+ Kf8 10.Qxe4 Bxc3+ 11.bxc3 d5 12.Qf4+ Kg8 13.0-0 c6 14.Qg3 Bf5 15.Bg5 Qd7 16.f4 Bxc2 17.Qe3 Bf5 18.Rf3 Re8 19.Rg3 g6 20.Bf6 Kf7 21.Bxh8 Rxh8 22.Qd4 Re8 23.Qxa7 Be4 24.Qe3 Kg8 25.Rg5 Rf8 26.Rf1 Ra8 27.c4 Rxa2 28.cxd5 cxd5 29.Qb3 Rc2 30.Re1 h6 31.Rg3 Qc6 32.Rxe4 Rc1+ 33.Kf2 Rc2+ 34.Re2 Qc5+ 35.Rge3 Rxe2+ 36.Kxe2 Black resigned, jfhumphrey - richiehill, FICS, 2009.

8.Nxe4 Bb4+

This is actually better than either 8...Bxd4 (yorgos -josephjorkens, FICS, 2009, [1-0,45]), 8...Be7 (perrypawnpusher - sdockray, blitz, FICS, 2010 [1-0, 28] or 8...Bb6 (perrypawnpusher - BallsOfFire, blitz, FICS, 2010, [aborted by adjudication, 9]).

9.c3 d5

10.Ng5+ Kg6

The King would be safer at g8. 

11.dxe5 Bc5


Since Black removes a piece from danger and points it at f2, it is not immediately clear that this move makes his situation worse. 

After the game Rybka suggested 11...h6 12.Nh3 Bxh3 13.gxh3 Bc5 14.Rg1+ Kh7 15.Qd3+ Kg8 16.Be3 Bxe3 17.Qxe3 c6 18.0-0-0 Qe7 when White is stll better, but his advantage is less than after the text.

12.h4

I was so happy with the "boldness" of this move that it took me a while to realize that I had actually moved the wrong pawn.

After 12.g4, Black has no time for 12...h6, as 13.Qd3+ Bf5 14.Qxf5 is mate. His best defense, 12...Qf8, still would lose a piece to 13.Qc2+ and after 13...Bf5 White can even throw in the gnarly 14.h4! just to see if Black is paying attention.

  



analysis diagram







Of course, if Black now takes the Queen it is 15.h5 mate. However, after 14...h5 the King is okay for the moment, and White has to settle with winning the Bishop after all with 15.gxf5+.

12...h5

13.0-0

Rybka prefers 13.Qd3+ but there are still some fireworks left in the position. 

13...Bg4

My opponent understandably guards against dicovered checks.

Again, Rybka, which, after the game, understood more than either richiehill or I did, suggested 13...Bf5. After 14.Qf3 Be7 White has the leap 15.Nf7 which either wins the exchange or, after 15...Kxf7 16.Qxf5+ Kg8 allows White to build the pressure with 17.Bg5.





analysis diagram







14.Qd3+ Bf5 15.Qg3 Bg4


Again, the Bishop shields the King. Against what? Rybka gives a peek: if instead 15...Qe7, then 16.Bf4 Rhf8 17.Ne4+ Kh7 18.Bg5 Bxe4 19.Bxe7 Bxe7 and White has won the Queen for two pieces.

16.Be3

Still worrying about that Bishop on c5!

It turns out that there was another Knight leap available to White: 16.Ne6 Qe7 17.Nxc5 Qxc5 18.Be3 Qe7 19.f3 and the shield (Black's Bishop) has become the target!

16...Qe7 17.f4

Hoping to get something going by advancing the "Jerome pawns", but Black's heroic Bishops can again thwart much of that with 17...Bxe3+ 18.Qxe3 Bf5.

17...c6


Taking a breath to shore up his position, Black lets the pawn distract the powerful prelate...

18.f5+ Bxf5

If 18...Kh7 then 19.f6 rips the position open. The text move finally allows a discovered check, winning a piece.

19.Ne4+ Black resigned

Platinum Mind Tricks

I had another encounter with what I have called a Blackburne Shilling Gambit "Jedi Mind Trick". My opponent was PlatinumKnight, so perhaps I should refer to it as a "Platinum Mind Trick".


perrypawnpusher - PlatinumKnight
blitz, FICS, 2010

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


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

The updated New Year's Database has 60 examples of games by my opponent in this line: 58 with Black, 2 with White. Two have already appeared on this blog, one against darrenshome and another against richiehill.

4...Ke7


Messing with my mind (4...Kxf7 was just fine)...

After our game I learned that PlatinumKnight is a bit of a specialist with this strategy, as the Database has 30 of his games with 4...Ke7, starting in 2005. 

5.Bc4

Also possible, of course, are 5.Bxg8 or  5.Bb3.

5...Ke8


A striking move, played, I imagine, to allow Black's Queen to regain access to the d8-h4 diagonal. Indeed, we have the original Blackburne Shilling Gambit position, except that Black's f-pawn is missing and Black's King cannot castle – neither will be important if he can pull off the usual BSG shenanigans.

6.Nxd4

I suspect that PlatinumKnight was hoping for 6.Nxe5, which he could answer with 6...Qg5 (and a roughly equal position) but I've learned my lesson from Master zadox.

I don't think that my opponent has faced 6.Nxd4 in this position before. Perhaps it will help him give up attempts at "mind tricks".

6...exd4

It is sad that after the game all Rybka had to recommend instead of this recapture was: 6...Qh4 7.Nf3 Qxe4+ 8.Be2 Qf5 when White is much better.

7.Qh5+


7...g6 8.Qe5+ Ne7

Or 8...Qe7, as in perrypawnpusher - zadox, blitz, FICS, 2010 (1-0, 14).

9.Qxh8 Black resigned
