Trying To Escape The Inevitable

The following game reminds me of Douglas Adam's comment, above. I am not exactly sure why.

Wall, Bill - Guest2901729, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.


The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke7 6.c3 Ne6 

It is already possible to see where danger might strike Black: along the d8-h4 diagonal, where his King and Queen are lined up; or in the center, where White's "Jerome pawns" can cause mischief.

7.d4 d6 8.Nd3 Nf6 9.d5

Best according to Stockfish 7. 

Interesting was 9.Qe2 as in Philidor 1792 - g-chessman1518,, 2015(1-0, 22).

9...Nc5 10.Nxc5 dxc5 11.e5

An improvement over the older 11.f3 Ke8 12.O-O Be7 13.c4 Kf7 14.e5 Nd7 15.e6+ Ke8 Black resigned, AMITAF - UofM, FICS, 2010.


Trying to escape the inevitable. He should have given up the Knight directly.

12.Bg5+ Nf6 13.exf6+ gxf6

Or 13...Ke8 14.Qxd8+ Kxd8 15.fxg7+ Kd7 16.gxh8=Q Be7 17.Qxh7 Kc6 18.Qxe7 Bd7 19.b4 Re8 20.Qxe8 Bxe8 21.bxc5 Kxc5 22.Nd2 b6 Black resigned, EdoTK - Jorma, FICS, 2006.

14.Bxf6+ Black resigned

Ouch! The Queen is lost.

Go On, Take The Money And Run

Black does well defending against the Jerome Gambit in the following game, until he becomes careless, and all of his gains disappear quickly.

Wall, Bill - Guest2905635, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ Kxf7

The Italian Four Knights Jerome Gambit, a transition from 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 Nf6.

6.d3 Re8


6...Ng4 7.Ng5+ Ke8 (7...Kg8 as in Wall,B - Richard123,, 2010 [1-0, 10]) 8.Qxg4 h6 9.Qh5+ Ke7 10.Qf7+ Kd6 11.Nb5 checkmate, Wall,B - 321, InstantChess, 2015; or

6...Bb4 7.O-O Bxc3 8.Ng5+ Kg8 9.bxc3 h6 10.Nf3 d5 11.exd5 Qxd5 12.Be3 Bg4 13.c4 Qd8 14.h3 Be6 15.Rb1 b6 16.Re1 e4 17.dxe4 Bxc4 18.e5 Nd7 19.Qd2 Bxa2 20.Rbd1 Be6 21.Qc3
Ne7 22.Nd4 Bd5 23.Nf5 Nxf5 24.Rxd5 Ne7 25.Rd4 c5 26.Qc4+ Kh7 27.Qd3+Kg8 28.Rxd7 Qf8 29.Ra1 Nf5 30.Qd5+ Kh7 31.Rf7 Qg8 32.e6 Black resigned, Wall,B - Boris,, 2012; or

6... Bxf2+ as in Wall,B - Igidius,, 2015 (1-0, 15); or

6... Rf8 as in Wall,B - BarAbbas,, 2012 (1-0, 45) 

7.O-O g6

Instead, 7...Nd4 was seen in Wall,B - Albulus,, 2015 (1-0, 44).

8.Nd5 Nxd5 9.exd5 Ne7 10.Nxe5+ Kg8 11.Bg5 d6 12.Nf3 Qd7

Black has unpinned his Knight and plans to grab the advanced d-pawn. It looks like a simple idea.

13.d4 Bb6 14.Re1 Nxd5 15.c4 Ne7


16.c5 dxc5 17.Qb3+ Kf8 18.Bh6 checkmate

Computer-Style Moves

As a way of lightening up a bit after the last post "Nightmare" I wanted to present a human vs computer engine game where the human wins - thanks, in part, to some very odd computer-style moves. 

I remember, many years ago, when I would play against Fidelity's "Chess Challenger 7", it was apparently programmed so that when it could see no way to improve its position, it would advance either its a-pawn or its h-pawn. (Yes, I have played the Jerome Gambit against it.)

Wall, Bill - BBchess engine
Palm Bay, FL, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Qf6

8.Rf1 g6 9.Qh3+ Ke7

Already seen:

9...Kf7 10.fxe5 Qxf1+ 11.Kxf1 d6 12.Qc3 Black resigned, Wall,B - Guest1690223,, 2012; and

9...Ng4 10.Qxg4+ Ke7 11.Nc3 d6 $2 12.Nd5+ Kd8 13.Nxf6 Bxg4 14.Nxg4 h5 15.Nf2 Kd7 16.Nh3 Re8 17.d3 Nf6 18.Ng5 Ng4 19.h3 Nh2 20.Rh1 Black resigned, Wall,B - Guest3164644,, 2013.

10.Nc3 d6 11.Nd5+ Kd8

Or 11...Kf7 12.Qb3 Qh4+ 13.g3 Qg4 14.fxe5+ Kg7 15.d3 dxe5 16.Nxc7 Rb8 17.Ne8 checkmate, Wall,B - Guest5541035,, 2014

12.Qg3 Nd3+ 

Or 12...Qe6 13.fxe5 dxe5 14.d4 Ne7 15.dxc5 Nxd5 16.Bg5+ Ke8 17.exd5 Qxd5 18.Rf2 Be6 19.Rd2 Qxc5 20.O-O-O Rf8 21.Qh4 h5 22.Bh6 Rf5 23.Rd8+ Rxd8 24.Rxd8+ Kf7 25.Rf8+ Qxf8 26.Bxf8 Kxf8 27.Qd8+ Kg7 28.Qxc7+ Kh6 29.h4 Rf1+ 30.Kd2 Rf2+ 31.Ke3 Rf5 32.Qd8 a6 33.Qh8 checkmate, Wall, B - Aburasian,, 2010. 

13.Qxd3 Qg7 14.c3 Ne7 15.b4 Bb6 16.Nxb6 axb6 17.Qc2 Qh6 18.h3 Qh4+ 19.Rf2 Be6 20.d3 Rf8 21.a4 Qg3 22.Kf1 Qh2

It is not clear what the computer "hopes" to accomplish with this Queen infiltration. Her Majesty ultimately gets imprisoned in her forward outpost. 

23.Rf3 Qh1+ 24.Kf2 Bd7 25.b5 Be6

*What to do? What to do? What to do?*

26.c4 Kd7 27.Qc3 Rg8

28.Bd2 Qh2 29.d4 Bf7 30.e5 Nf5 31.d5 Rge8 32.Re1 Nh4

Perhaps BBchess first looked at 32...Rxa4 33.e6+ Bxe6 34.dxe6+ Rxe6 35.Rxe6 Kxe6 gaining 3 pawns for its piece, only later to uncover the sharp 36.c5!? 

33.e6+ Kc8 34.Rg3 Bxe6 35.dxe6 Rxa4

Black's pieces are uncoordinated, especially the Queen.

36.Qb3 Ra8 37.Qb2 Kb8 38.e7 Nf5 39.Rg5 d5

The advanced e-pawn is untouchable, as 39...Rxe7 leads to mate after 40.Qh8+ while 39.Nxe7 is well met by 40.f5!?

40.Rxf5 gxf5 41.cxd5 Ra4 42.Qe5 Ra2 43.Qd4 h5 44.d6 cxd6 45.Qxd6+ Ka8 46.Re6 Rc2

Black has found a round about way to link Rooks, but it is too late.

47.Qd8+ Rc8 48.Qxb6 Rg8 49.Rg6 Rxg6 50.Qxg6 h4 51.e8=Q Black resigned
