Lots of Practice, Some Theory

Today's blog is full of games relevant to our main one. There is a little bit of "theory" tossed in, too. Enjoy the efforts of steveod and PEITONER.

PEITONER - steveod

The Blackburne Shilling Gambit.


The Blackburne Shilling Jerome Gambit. Black may be hoping for 4.Nxe5?!, and he may be expecting 4.Nxd4, 4.c3, 4.d3 or 4.0-0; but now he has something new to think about.

In this case, over the last decade plus, steveod has played quite a few BSGs at FICS, faced quite a few BSJGs, and even played a few himself. I thought it would be interesting to share his experiences as they appear in The Database, positive and negative. His games provide a pretty good overview of the Blackburne Shilling Jerome Gambit.

Let me start by presenting a Jerome Gambit / Blackburne Shilling Jerome Gambit hybrid game: 4.Nc3 Bc5 5.Bxf7+ Kxf7 6.Nxe5+ Ke6 7.Qg4+ Kxe5 8.f4+ Kd6 9.e5+ Kc6 10.b4 d5 11.Qg3 Nxc2+ 12.Kd1 Nxa1 13.b5+ Kb6 14.Qd3 c6 15.Na4+ Kc7 16.Nxc5 b6 17.Na6+ Bxa6 18.bxa6 Ne7 19.Ba3 Ng6 20.Bd6+ Kc8 21.Qf5+ Qd7 22.Qg5 Re8 23.Rf1 Ne7 24.Qxg7 Nf5 25.g4 Nxg7 White resigned, crystalleaf - steveod, FICS, 2013


I have not promoted declining the gambit, in fact I have referred to it as intending some kind of "Jedi mind trick", but I note that steveod has played several games with 4...Ke7:

8.d3 Bb4+ 9.Nc3

A natural response.  In "The Threat Is Greater..." I mentioned the two alternatives, 9.Ke2!? and 9.Kf1!?, which threaten to win a piece after 9...Ke5 10.Qb3 followed by 11.Qxb4. The Database shows that these suggestions have yet to be followed.


Or 9...Bxc3+ 10.bxc3+ Ke5 (10...Kxc3 11.0-0 Qf6 12.Be3 Kb4 13.Rb1+ Ka5 14.Qb3 c6 15.Qa3 checkmate, Edisce - nkm, FICS, 200511.f4+ (11.Qh5+ was the correct move, as in perrypawnpusher - AdamRou, blitz, FICS, 2010 [1-0, 28]) 11...Kf6 Black forfeited by disconnection, kocanda - ETERHERE, standard, FICS, 2014


White could also whip up an attack with 10.d4+ Kf6 11.Qf3+.

10...Nf6 11.d4+ Ke6 12.Qb3+ 

The Queen goes to b3 and then captures the Bishop, after all. (See the note to White's 9th move.)

12...d5 13.Qxb4 Kf7 

White's center pawns help him take command.

14.e5 Ne4 15.Nxe4 dxe4 16.f3 a5 17.fxe4+ Ke8 18.Qc4 Rf8 19.Rxf8+ Kxf8 20.Be3 c6 21.Rf1+ Ke7 22.Qf7 checkmate
