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.
