Blackburne Shilling Jerome Gambit: Risk vs Experience

The following game is a riot of a 3-minute battle, as White takes risks and even more risks, while Black relies on his experience in the line - up to a point. This time, fortune favors the bold - but only half-way.

By the way, shugart has 140 games in The Database, scoring 60%. Nice.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit. White has alternatives, but this move is a lot of fun.

4...Kxf7 5.Nxe5+ Ke6 6.Qg4+ 



Tempting, as we have seen before (for example "Jerome Gambit: Missed by That Much") - especially in blitz games - but best, from experience and by analysis, is 6.c3. 

6...Kxe5 7.f4+ 

In for a penny, in for a pound.

Boggus has grabbed the Knight before, for example: 7.c3 Nc2+ 8.Kd1 Nxa1 9.d4+ Kd6 10.Na3 h5 11.Nb5+ Kc6 12.d5+ Kxb5 13.Qe2+ Kb6 14.Be3+ c5 15.a4 Kc7 16.Qb5 d6 17.Bf4 Kb8 18.Qxc5 Qb6 19.Qc4 Qxb2 20.Ke1 Nc2+ 21.Kf1 Qb1+ 22.Ke2 Qxh1 23.Qb3 Qe1+ 24.Kf3 Bg4+ 25.Kg3 Qxe4 26.f3 Bxf3 27.gxf3 h4+ 28.Kh3 Qxf3+ 29.Bg3 hxg3 checkmate, Tigrann - boggus, FICS, 2008.

White could have tried 7.Qh5+ (e.g. 7...Kf6 8.d3 Ne7 9.Bg5+ Ke6 10.Bxe7 Nxc2+ 11.Kd1 Kxe7 12.Kxc2 d6) but he will eventually be done in by his generosity.

Better to remember the 6.c3 line for next time.

7...Kd6

The two likely reasons White likely sacrificed the Knight are these alternatives: 

7...Kxe4 8.Nc3 checkmate; and

7...Kf6 8.Qh4+ Kf7 9.Qxd8. 

Don't laugh. Such threats are the meat and potatoes of blitz chess.

8.e5+

White might as well keep attacking, as the more prudent 8.Na3 c6 9.c3 Nb5 10.Nxb5+ cxb5 doesn't get him out of his material deficit.

8...Ke7 

Black played the stronger 8...Kc6 in two earlier games, but they were long ago: 9.Qd1 (9. c3 Nc2+ 10.Kd1 Nxa1 11.Qf3+ d5 12.b4 a6 13.a4 Be6 14.c4 Bxb4 15.Bb2 Qd7 16.Bxa1 Bg4 17.cxd5+ Qxd5 18.Qxg4 Ne7 19.Qxg7 Rhd8 20.Qf6+ Kc5 21.Qxe7+ Kc4 22.Qxc7+ Qc5 23.Qxc5+ Bxc5 24.Ke2 Bd4 25.Bxd4 Rxd4 26.d3+ Rxd3 27.Rc1+ Kd4 28.Rc7 Rd8 29.g4 Ke4 30.Rc4+ R3d4 31.Rxd4+ Rxd4 32.Nd2+ Kxf4 33.e6 Rd8 34.g5 Kxg5 35.Ne4+ Kf5 36.e7 Re8 37.Nd6+ Ke6 38.Nxe8 Kxe7 39.Ng7 Kf7 40.Nh5 Ke6 41.Ng3 b5 42.Nf1 b4 43.Kd2 a5 44.Kc2 Kd5 45.Kb3 Kd4 46.Nd2 Kd3 White forfeited on time, GROFVLAD - boggus, FICS, 20079...d5 10.c3 Nf5 11.O-O b6 12.d4 Ba6 13.Rf2 Qh4 14.Nd2 Nge7 15.Nf3 Qh5 16.e6 Kb7 17.Ne5 Nc6 18.b4 Qxd1+ White resigned, GOH - boggus, FICS, 2009.

Still, if he keeps his wits about him, all will be well for Black. 

9.f5 Nxc2+

Often in the BSJG the Rook on a1 is poisoned, but not in this case. You have to wonder though - was Black a little bit suspicious as to why White let it go? Did it nag at him: Maybe White is up to something...?

10.Kd1 Nxa1 

True, 10...d5 is probably best, but Black is still better after the game move.

11.d4 

Hopeful. If you don't have hope, you can't play Jerome lines.

11...h6 

We know why Black played this.


It would be very impressive if it was because he remembered the following game: 11...d5 12.Bg5+ Nf6 13.exf6+ gxf6 14.Re1+ Kd6 15.Bf4+ Kc6 16.Re3 Bd6 17.Rc3+ Kd7 18.Bxd6 cxd6 19.Nd2 Qg8 20.Qh3 Qg5 21.Nf3 Qf4 22.Qh5 Qe4 23.Qf7+ Qe7 24.Rc7+ Kxc7 25.Qxe7+ Kb6 26.Qxd6+ Kb5 27.Qxd5+ Kb6 28.Qc5+ Ka6 29.b4 b6 30.b5+ Kb7 31.Qc6+ Kb8 32.d5 Bxf5 33.d6 Rc8 34.Qd5 Rc5 35.Qg8+ Kb7 36.Qxh7+ Kc8 37.Qg8+ Kb7 38.Qf7+ Kc8 39.Qe8+ Kb7 40.Qe7+ Kb8 41.Nd4 Bc2+ 42.Ke1 Bf5 43.Nc6+ Kc8 44.Qd8+ Kb7 45.Qc7 checkmate, GOH - boggus, FICS, 2004

Black wants the Black Bishop to stay away from g5, but White now grabs the half-point on the table.

12.Qh4+ Ke8 

The alternative, 12...g5, is met by 13.Bxg5+ hxg5 14.Qxg5+ Ke8 15.Qg6+ Ke7 16.Qg5+ etc.

13.Qh5+ Ke7 14.Qh4+ Ke8 15.Qh5+ Ke7 16.Qh4+ drawn by repetition
