Even Veterans Meet Something New

White has over 600 games in The Database. He has seen a lot in the Jerome Gambit world. In the following game, he encounters something new. I've added a few games and ideas, for when he meets it again.

yorgos - gruzanin
blitz, FICS, 2014

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 

The standard counter to Black's threat to the White Knight - threaten the Black Knight. After the "exchange" of Knights now with 6...Kxe5 7.cxd4+ there are 233 examples in The Database, and White scores 61%,

6...Nc2+

A creative idea.

7.Qxc2 Kxe5 8.d4+

Alternatives:

8.O-O Ke6 9.d3 (9.Qb3+ Ke7 10.d4 d6 11.Bg5+ Nf6 12.e5 d5 13.Nd2 h6 14.exf6+ gxf6 15.Rfe1+ Kf7 16.Bh4 c6 17.Nf3 b6 18.Ne5+ Kg7 19.Qd1 Qd6 20.Ng4 Be7 21.Rxe7+ Qxe7 22.Bxf6+ Qxf6 23.Nxf6 Kxf6 24.Qf3+ Kg6 25.Qf4 Re8 26.h4 Re4 27.h5+ Kxh5 28.Qf7+ Kg5 29.f3 Re6 30.Kf2 Rg6 31.Rh1 Be6 32.f4+ Black resigned, Coaque - Nikilady, FICS, 2012)  9...Kf7 10.Be3 d6 11.Nd2 Nf6 12.Qb3+ Ke8 13.Rfe1 Be7 14.Bd4 Rf8 15.e5 Ng4 16.e6 c6 17.Qd1 Nf6 18.Qa4 Qc7 19.c4 d5 20.g3 Kd8 21.c5 g6 22.Be5 Qxe5 23.Rxe5 Bxc5 24.e7+ Bxe7 25.Rxe7 Kxe7 26.Re1+ Kf7 27.Nf3 Bf5 28.Qb4 Rfe8 29.Qxb7+ Kg8 30.Rxe8+ Rxe8 31.Qxc6 Kg7 32.Qc7+ Kh6 33.Ne5 Rc8 34.Qxa7 Bh3 35.Nf7+ Kh5 36.Qe3 Black resigned, Coaque - Nikilady, FICS, 2012.

Tricky, suggested by Stockfish 6, is 8. f4+!? Kf6 (8...Kxf4? 9.d4+ Kg4 10.Qe2+ Kh4 11.g3+ Kh3 12.Qf1+ Kg4 13.Qf5#) 9.d4 equal.

8...Ke6

Black's King is wise to head toward home.

White's center pawns balance Black's extra piece.

9.d5+

Again, not the only idea:

9.Qb3+ d5 10.exd5+ (10.O-O c6 11.exd5+ Qxd5 12.c4 Qxd4 13.Re1+ Kf7 14.Be3 Qf6 15.Nc3 Bd6 16.Ne4 Qe7 17.c5+ Be6 18.Nxd6+ Kf8 19.Qb4 Rb8 20.Bf4 b5 21.Nf5 Qf6 22.Bd6+ Kf7 23.Nxg7 Qxg7 24.Bxb8 Nf6 25.Be5 Rg8 26.g3 Bd5 27.Qf4 h5 28.Bd6 Kg6 29.Re7 Qh8 30.h4 Qh6 31.Qd4 Ng4 32.Rae1 Rf8 33.Qd3+ Rf5 34.Bf4 Qf8 35.f3 Bxf3 36.R1e6+ Nf6 37.Qxf3 Rd5 38.Qe4+ Rf5 39.g4 hxg4 40.h5+ Kxh5 41.Qxf5+ Kh4 42.Qg5+ Kh3 43.Re3+ g3 44.Qxg3 checkmate, graniglia - Knightslider, FICS, 2000) 10...Qxd5 11.Qc2 Qxg2 12.Qe2+ Kd7 13.Rf1 Kd8 14.Nd2 Qxh2 15.Nf3 Qd6 16.Bg5+ Be7 17.Bxe7+ Qxe7 18.Ne5 Be6 19.O-O-O c6 20.f4 Kc7 21.Rde1 Nh6 22.Nc4 Rhe8 Black won by adjudication, ralte - Nikilady, FICS, 2012. 

Stockfish 6 suggests the reasonable 9.O-O. 

9...Kf7 10.f4

Continuing with the "central pawn" theme, but Black has a counter that begins to sway things in his favor.

Two other ideas:

10.O-O Nf6 11.f4 (11.e5 Nxd5 12.c4 Nb4 13.Qf5+ Kg8 14.a3 g6 15.Qe4 Nc6 16.Rd1 Bg7 17.f4 Qe7 18.Nc3 Qc5+ 19.Kh1 d5 20.exd6 cxd6 21.Qe8+ Bf8 22.Nd5 Rb8 23.f5 Bxf5 24.Qe2 Bg7 25.b4 Nxb4 26.Ne7+ Kf7 27.Nxf5 gxf5 28.axb4 Qxb4 29.Ba3 Rbe8 30.Qh5+, Black resigned, Darrenshome - tomcatx, FICS, 2010) 11...Bc5+ 12.Kh1 Ng4 13.b4 Bb6 14.c4 Bd4 15.Bb2 Ne3 16.Qe2 Bxb2 17.Qxb2 Nxf1 18.Nd2 Nxd2 19.Qxd2 d6 White resigned, jesusramon - ninofaca, FICS, 2014;

10.e5 Ne7 11.Bg5 Kg8 12.d6 cxd6 13.exd6 h6 14.dxe7 Bxe7 15.Bxe7 Qxe7+ 16.Kd1 d5 17.Re1 Qf7 18.Qa4 Kh7 19.Nd2 Qxf2 20.Kc2 Bf5+ 21.Kc1 Qxe1+ 22.Qd1 Rhe8 23. Qxe1 Rxe1 checkmate, HomogenousMass - jantonacci, FICS, 2009. 

10...Qh4+ 11.g3 Qh3 12.Qf2 d6 13.Nd2 Bg4 14.Nc4 b5 15.Ne3 Nf6 16.Nxg4 Qxg4 

White has dealt with threats on the Kingside, but that has taken time. As a result, his King is not yet castled - something that puts his center "Jerome pawns" (and their advance) at risk. The little things add up.

17.h3 Qd7 18.e5 dxe5 19.fxe5 Re8 20.Be3 Rxe5 21.O-O Kg8 

After the final center pawn disappears, White's game collapses.

22.Bd4 Rxd5 23.Qe2 Bd6 24.c4 Rxd4 25.Rfd1 Bc5 26.Kh2 Ne4
27.Qe3 Rxd1 White resigned

White has lost material and is near checkmate.

Pathbreaking

Exploring an opening variation has its excitements and its drawbacks. Often it is best, once the end of the trail is reached, to reflect on the path travelled – in case you go that way again.


AMITAF - aditikalpesh
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.f4

Common, but perhaps not best. This move allows Black chances that he does not take advantage of in this game.

6...Bd6

An odd sideline that puts Black at great risk. He needed to play 6...Qh4+ 7.g3 Qh3 with possibilities of infiltrating on the Kingside.

7.c3

Solid.

Next time White can come armed with 7.Qg4+ Kf6 (or 7...Ke7, jamci - tpg, FICS, 2009 [1-0, 26]; Handlangari - PlatinumKnight, FICS, 2007 [1-0, 9] and bushytail - PlatinumKnight, FICS, 2009 [1-0, 9]; or 7...Nf5 8.Qxf5+ Cyberkid - PlatinumKnight, FICS, 2009 [1-0, 8]) 8.Qg5+ wayaut - tomcatx, FICS, 2010 [1-0, 8] and Pandolfl - screaminghead, FICS, 2005 [1-0, 15]

7...Nc6

Lost.

Better: 7...Bxe5 while he has the chance. (Hint: White's best response would be 8.0-0, and he would be worse.)

8.d4

Again, the short cut next time would be 8.Qb3+ Ke7 9.Qf7 checkmate 

8...Nb8

Danger.

Again, 8...Bxe5 was the choice, with White only slightly better.

9.f5+

This leads to White's advantage. 

So, too, would 9.Qb3+ Kf6 10.Qf7 checkmate. 

9...Ke7 10.Bg5+ Nf6

The brutal pin on the Black Knight at f6 and the possibility of forking the Knight and Bishop with a pawn (once White's Knight is out of the way after 11.Ng4) give White a clear advantage.

11.Nd2 h6

Certainly Black should have tried to remedy the ills mentioned above with 11...Kf8 12.Nd3 Be7 13.e5 h6 14.Bh4 Nd5 15.Bxe7+ Qxe7 16.Qf3 Qf7 17.0-0 Nc6 18.Rae1 Kg8, although White would still be for choice.

Now the wilderness swallows him up.

12.Ng6+ Kf7 13.Qb3+

13...Ke8 14.Nxh8 hxg5 15.Qf7 checkmate
