The Threat Is Greater...


Here we have another Blackburne Shilling Jerome Gambit game, giving an opportunity to share some speculation, and to once again ponder the aphorism that "the threat is greater than its execution".

kocanda - ETERHERE

standard, FICS, 2014

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 8.d3 Bb4+ 




9.Nc3 


Both 9.Ke2!? and 9.Kf1!? are mentioned in the notes to perrypawnpusher - AdamRou, blitz, FICS, 2010 (1-0, 28) and pigsfeet - jantonacci, blitz, FICS, 2011 (1-0, 14), but do not yet appear in any games in The Database.


The ideas: 9.Ke2 Ke5 10.Qb3 and White's mate threats allow him to grab the Black Bishop on the next move; or 9.Ke2 d5 10.Bf4 and White's Queen again will soon arrive at b3.


Similar attacking plans work for White after 9.Kf1.



9... Bxc3+ 10. bxc3+ Ke5 11. f4+ 



The "Jerome pawns" look scary, but the best move for White, instead, was 11.Qh5+ as in perrypawnpusher - AdamRou, blitz, FICS, 2010. 


11...Kf6  Here Black forfeited by disconnection.


White may have a dangerous attack coming (although Houdini 3, at 25 ply, rated the position 0.00) but Black can continue to retreat his King, and declare "Show me!"


Perhaps other things were more pressing in Black's life away from the board.

Yet Another Day in the Life of the Jerome Gambit


I like to use the "day in the life" games to show just how other-worldly the Jerome Gambit can become.

pigsfeet - chessnyc
blitz, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 Bc5 5.Bxf7+




There are over 900 examples of this Jerome Gambit version in The Database.

5...Ke7

Black is not interested in the piece, however, at least for now. Already he has exchanged a winning advantage for a losing one. Yawn.


6.c3

White insists, however, and Black doesn't have to be asked twice.

6...Kxf7 7.b4 Bxf2+

Why should White have all the fun?

8.Kxf2 Rf8 9.Ba3 d6 10.Qb3+ Be6

This "aggressive counter" falls to a known tactic. The game would be roughly even after 10...Ke7.

11.Ng5+ Kg6 12.Nxe6 

White grabs back a piece, and will next win an exchange.

12...Qe7 13.Nxf8+ Rxf8 14.Rf1



Planning to castle-by-hand, White relaxes too soon. He is saved when Black's Knight moves to the left instead of to the right.

14...Nxe4+

Rybka 3 point out that 14...Ng4+ was the way to go, i.e. 15.Ke2 Rxf1 16.Kxf1 Qf6+ 17.Ke2 Qf2+ 18.Kd1 Ne3+ 19.Kc1 Qe1+ 20.Kb2 Qe2+ 21.Kc1 Kg5 22.h3 Qe1+ 23.Kb2 Qf2+ 24.Kc1 b5
Analysis Diagram

when White's pieces are all tied up, and Black will win with a timely ...a5, when his other Knight can enter the game (or simply capture White's Kingside pawns and Queen one of his own). Weird!




15.Kg1 Nd2


As you might expect from the analysis above, Black had a draw here with 15...Rxf1+ 16.Kxf1 Qf6+ 17.Ke1 Qf2+ 18.Kd1 Nxc3+ 19.Nxc3 Nd4 20.Qb2 Qg1+ 21.Kd2 Qf2+ 22.Kd1 Qg1+ etc.

The move in the game looks like a slip, perhaps a hallucination.

16.Nxd2 Rxf1+ 17.Rxf1 Qh4



Here Black resigned, as he has only a pawn for his missing piece. Indeed, White has a forced mate in 6.

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.
