Blackburne Shilling Jerome Gambit: Black Runs Out of Energy

In the following game Black is vigorous in his response to White's gambit. However, he seems to run out of energy at the end. Is being down 5 pawns for a piece reason enough to resign? In this case, perhaps not: Stockfish 8 evaluates the final position as even.

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4


The Blackburne Shilling Gambit.

4. Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 hxg6 8.Qxg6+


8.Qxh8 is a mistake, but I once managed to win with it anyhow, perrypawnpusher - tampajake, FICS, 2009 (1-0, 12).

8...Ke7 9.Qg5+ Nf6

Better than 9...Ke8 in perrypawnpusher - adamzzzz, FICS, 2009 (1-0, 39).

10.Qc5+

Better than 10.e5 in perrypawnpusher - JokeritT, FICS, 2010 (1-0, 28).

10...Kf7

I faced 10...d6 in a number of games; perrypawnpusher - foreverblackman, FICS, 2010 (1-0, 21); perrypawnpusher - vlas, FICS, 2010 (0-1, 23); perrypawnpusher - theferno, FICS, 2010 (1-0, 28); perrypawnpusher - Raankh, FICS, 2010 (1-0, 49); and perrypawnpusher - michon, FICS, 2015 (1-0, 36). Bill, too: Wall,B - Guest5170841, PlayChess.com 2015 (1-0, 15 ).

11.Qxd4 Qe8 12.Nc3 c5 13.Qe3 Qe5 14.h3 Bh6 15.Qf3 Qf4 16.Qe2 d6

Black is fighting back vigorously, despite his slightly exposed King. Still, I am always suspicious of ...c5 in these kinds of positions, as it can allow further opening of the game.

17.d4 Qh4 18.Bxh6 Qxh6 19.dxc5 dxc5 20.e5 Nh5 


Here Stockfish 8 recommends 21.g4!? which is not the kind of move that I can see Bill choosing, as it seems to give even more exposure to his King. Yet the followup is ironic enough for him to appreciate: 21...Nf4 22.Qf3 Kg7 23.0-0-0 (made possible by the Knight's block of the Queen's diagonal) Ne2+ 24.Kb1 Nxc3 25.Qxc3 Be6 with an advantage to White after he captures the c-pawn.

21.Qc4+ Be6 22.Qxc5 Black resigned


Interesting. Compared to Stockfish 8's analysis above, the Knights are still on the board, which would slightly favor White's better piece. However, White's King is not castled, which could be quite risky. 22...Rhd8 would seem to guard well against White's possible Queen check at c7.

In a human vs human game, however, in the long run I would take the extra pawns over the extra piece. It would appear that Black agreed.

Jerome Gambit: This Just Doesn't Seem to Be Her Day

In the Jerome Gambit Black's King is often the center of attention - being attacked. However, in the following game Black is able to place his King in a secure location; it is the Queen, instead, that faces all of the danger.

Wall, Bill - Banken
lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 



6...Bb4+ 7.c3 Bxc3+ 8.bxc3 Ng6 9.O-O 



The immediate 9.e5 was seen in Wall,B - PassCapture, lichess.org, 2016 (1-0, 22).

Which will prevail, the pawns or the piece?

9...Nf6 10.e5 Ne8 11.f4 Rf8 12.f5 Nh4 



The "Knight on the rim" is beginning to look rather "dim".

13.Qh5+ Kg8 14.Bg5 Rxf5 15.Rxf5 Nf6 



To save the Queen.

16.exf6 Qf8 17.f7+ Kh8 18.Qxh4 d6 19.Be7 Black resigned



Wow. Not one of her better days.

Non-Bxf7 Jerome Bukayev Gambit (for blitz)

Here is another creative idea from the inventive Yury Bukayev, as mentioned in a recent email. (I have added a diagram.)

What do readers think? 

Dear Rick, 
Here is my new gambit. It is very risky, like the Jerome Gambit. It is a non-Bxf7 relative of the JG. Here it is.
1.e4 e5 2.Nf3 Nc6 3.Bb5 Nge7 4.0-0 Nd4 5.Nxe5? Nxb5 6.Nxf7! Kxf7 7.Qh5+ with the idea Qxb5.
I suggest to play it to everyone who likes the Jerome Gambit. Its name will be "non-Bxf7 Jerome Bukayev Gambit (for blitz)".
Best wishes!Yury V. Bukayev
