Mate is Mate, Mate


Sometimes it is a good idea to be familiar with a line that leads to checkmate. You never know when it might show up on the board.


doubleabood - forland
blitz. FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ 




The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Qg5 




Black continues as if nothing has happened (6...Kxe5 is best), playing the thematic move of the Blackburne Shilling Gambit. As I've pointed out previously, with more and more insistance, (see "Reeling Sequel", "Finishing It Off Smartly", "Still A Bad Idea" and "Calling Black's Bluff"), White should take heart and proceed with his game - Black is headed toward his own checkmate.


Admittedly, not every player of the White pieces has been aware of his or her good fortune. Of the 50 games with this position in The Database, for example, White scored only 59%. 

7.cxd4 Qxg2 


Black strikes! Well, sort of. With 35 games in The Database, White scored 61%.

8.Qb3+ 


The key! Checkmate is forced.

White won in 7 of 9 games with this position in The Database (78%) but his two losses were time forfeits in winning positions.


That's better.

Finishing It Off Smartly




In the following game, when jfhumphrey applies the "Jerome cure" to the Blackburne Shilling Gambit, the two players head into a sharp variation where jordibc's thematic BSG Queen sally looks scary, but proves to be his undoing.



jfhumphrey - jordibc
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 Qg5


The main line of this variation is the Knight "exchange" 6...Kxe5 7.cxd4+. Instead, Black brings out an idea that is often very dangerous in the Blackburne Shilling Gambit.

As we will see, though, White is quite ready.

7.cxd4 Qxg2 8.Qb3+

The much less effective 8.Qg4+ was seen in perrypawnpusher-TheProducer, blitz, FICS, 2009 (1-0, 66).

8...Ke7

Black is simply being mated. Alternatives:

8...Kf6 9.Qf7+ Kg5 10.d3+ Kh4 11.Nf3+ Kh3 12.Qh5 checkmate, GOH - boggus, FICS, 2011;


8...Kd6 9.Qd5+ Ke7 10.Qf7+ Kd6 11.Nc4+ Kc6 12.Qd5 checkmate, XprezzChezz - borodin, FICS, 2009;


8...d5 when 9.Qxd5+ Kf6 10.Qf7+ Kg5 11.h4+ Kh6 12.d3+ Qg5 13.hxg5 would have been checkmate; instead, White played 9.exd5+, achieved an advantage, but lost on time in 37 moves in ReallyBadPlayer - skipi, FICS, 2006.

9.Qf7+ Kd6 10.Nc4+ Kc6 11.Qd5 checkmate
