More Useful Junk


Readers of this blog probably remember Chris Torres. He hosts the Chess Musings blog.

He presented the Jerome gambit game Amateur - Blackburne, London  as "The Most Violent Chess Game Ever Played!"

He followed up with "Another Lesson in the Jerome Gambit", giving one of his own games.

He shared another game with the delightfully-titled post "Useful Junk: The Jerome Gambit".

Now he has sent me an FIDE-rated Jerome Gambit of his from the FIDE Online Arena.

Torres, Chris (chessmusings) - abhinam2
FIDE Online Arena, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 



Now Black has the choice of playing 7...d6, the Blackburne Defense, or 7...Qe7, the Whistler Defense. Instead, he opts for a "backatcha" move that at least gains him a pawn for his "doomed" dark-squared Bishop.

7...Bxf2+ 8.Kxf2 Nf6 9.Qf4

I thought I would share a few other ideas for this position, from games from The Database:

9... d6 

Perhaps not the risky 9...g5 10.Qf3 g4 as in instantcrow - KingEfraim, ChessWorld.net, 2005, (1-0, 25).

10.Nc3

Or 10.Rf1 Kg7 11.d4 h6 12.Kg1 Rf8 13.Qxh6+ Kf7 14.Qg5 Kg7 15.Qh6+ Kf7 16.Qg5 c6 17.e5 dxe5 18.dxe5 Ke6 19.exf6 Rxf6 20.Rxf6+ Ke7 21.Rxg6+ Black resigned, blackburne - Haroldlee123, ChessWorld, JG6, 2011. 

10...Kg7 11.d4 Rf8

Black is a pawn down, but he has castled-by-hand and his King is relatively safe. However, one of the "vital signs" that observers of all Jerome Gambits must note is the status of Black's light-squared Bishop, and its related Rook, as their under-development always are unhealthy symptoms. (See "A Lesson Learned From The Jerome Gambit" for one related "illness".)

12.Qh6+ Kg8 13.Kg1 Ng4 14.Qg5 Qxg5 15.Bxg5 Nf2 16.Nd5 Nxh1 17.Nxc7 Rb8 18.Kxh1 Bd7



White has two pawns for the exchange. Black can be happy that the Queens are off the board, but he cannot affort to be complacent. (He can be happy, for the moment, that his light-squared Bishop has moved and that his Rooks are linked, even if one is mysteriously developed.)

19.Nd5 Be6 20.Nf6+ Kg7 21.d5 Bc8

See the previous note.

22.Rf1 h6 23.Nh5+ gxh5 24.Bxh6+ Kxh6 25.Rxf8 



Materially, White has 3 extra pawns while Black has the extra piece.

More importantly, positionally, look at Black's Queenside: Code Blue! His weakness allows a "Jerome pawn" infection...

25...Kg7 26. Rd8 b6 27.Kg1 Ra8 28.e5 dxe5 29.d6 Bb7 30.Rxa8
Bxa8 31.d7 Kf7 32.d8=Q Black resigned



Very nicely done!

Choose the Simple, Avoid the Complex

Those who play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) know that it is a good idea to take advantages of the tricks and traps of the opening, when they arise. The last thing that they need is a "routine" game that leads to a "routine" loss.

The same goes for those who play the Blackburne Shilling Jerome Gambit.

pianazo - foduck
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+ Ke8 6.Qh5+

More often played than yesterday's game's 6.c3.

6...Ke7


Not quite a year ago, the post "Instant Victory" laid out the reasons for White to rejoice at seeing this move. It seems fitting to mention that the player handling the Black pieces back then is the one handling them in this game, too.

7.Na3

This is pianazo's attempted improvement over the 7.c3 that he used in two losses against Fission earlier this year (0-1, 34 and 0-1, 35).

My recommendation is 7.Qf7+ Kd6 8.Nc4+ Kc5 9.Qd5+ Kb4 10.c3+ Ka4 11.Qa5 checkmate.

7...Nf6

Black realizes that he needs to chase away the White Queen, but the way to do that was 7...Qe8.

8.Qf7+


Hunting the King is the right idea.

8...Kd6 9.Nac4+ Kc5


10.a3

White realizes that he has to weave a mating net around Black's King.

This move works, and quickly, but the situation is more complicated that it appears. It is not at all apparent at first glance that the Black King needs to be chased to the Kingside before being checkmated...

White's best is 10.a4, which actually forces mate. (I had the help of Houdini in my analyses.) 

Black struggles best against that move with 10...Nxc2+ (after 10...a5 it is possible to see the same kind of trouble afflict Black: 11.c3 d5 12.b4+ axb4 13.cxd4+ Kxd4 14.Bb2+ Kxe4 15.d3+ Kf5 16.g4+ Kg5 17.h4+ Kf4 18.Bc1 checkmate; the blocking 10...Ne6 leads to trouble faster 11.c3 Nxe4 12.d4+ Kd5 13.Ne3+ Kd6 14.Nf5+ Kd5 15.c4 checkmate), but not to win material.

11.Kd1 d5  (or 11...Qe7 and again we see the same pattern: 12.b4+ Kd4 13.Bb2+ Kxe4 14.d3+ Kf5 15.g4+ Kg5 16.h4+ Kf4 17.Bc1+ Ne3+ 18.Bxe3 checkmate; likewise with 11...b5 12.b4+ Kd4 13.Bb2+ Kxe4 14.d3+ Kf5 15.g4+ Kg5 16.h4+ Kf4 17.Bc1+ Ne3+ 18.Bxe3 checkmate) 12.b4+ when fleeing is "best" for Black, 12...Kd4 (or 12...Kxb4 13.Kxc2 Kc5 14.d4+ Kxd4 15.Rd1+ Kxe4 16.f3 Kf5 17.g4 checkmate)

The finish is familiar: 13.Bb2+ Kxe4 14.d3+ Kf5 15.g4+ Kg5 16.h4+ Kf4 17.Bc1+ Ne3+ 18.Bxe3 checkmate.

If pianazo had pulled that attack off in a blitz game, the Jerome Gambit Gemeinde would have crowned him "King For the Day (or Week, or Month, even)"!

There is a lesson here, though, from move 7: Choose the Simple, Avoid the Complex.

10...d6

More good fortune for White.

It turns out that it was okay for White to ignore Black's threat to win the Rook at a1. Had the game continued, instead, 10...Nxc2+, White could have put intense pressure on the Black King after 11.Kd1 Nxa1 12.b4 Ka5 13.a4+ Kxb4 14.Nd6!? c6 15.Qc4+ Ka5 16.Qc5+ Ka6 17.Nd3, when Black would have to give up his Queen with 17...Qa5 18.Nb4+ Qxb4 19.Qxb4

Black's King would still be alive, and he would have a Rook and two pieces for his Queen; but White would be able to keep the pressure on and regain some of the material, with advantage.

It looks like Black's best move was 10...Kb5 (hence the value of the recommended 10.a4 that would prevent the move). It is not clear what White is to do next. For example, 11.Nd6+!? Bxd6 12.Qc4+ Kb6 13.Qxd4+ Bc5 leaves Black's King alive, and close to finding shelter, as in 14.Qa5 d5 15.b4 Bxf2+ 16.Kxf2 a6, when White may still have an edge, but it is a small one.

Again, I applaud the creativity and courage of both pianazo and foduck in providing such an amazing game, but I have to repeat, sometimes it is better to Choose the Simple, Avoid the Complex.

11.b4+ Kb5 12.a4+ Kxb4 13.Nd3 checkmate




Very nice!

Good Luck



From the Good-Luck-Is-Better-Than-A-License-To-Steal Department comes the following end position from a Blackmar Shilling Jerome Gambit game


heckifiknow - pianazo, blitz, FICS, 2011
With White to move, it is stalemante.
