Jerome Gambit: Been Around A While

It can be fun to play over the games of experienced Jerome Gambit players and watch their struggles, successes and failures. The games of Petasluk show up in The Database starting in 2004 - he has been around the Jerome universe for quite some time.

The following game shows how a deadly center break-through and attack on the King can proceed when Black discontinues his defenses prematurely.

Petasluk - valli
5 0 blitz, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 



A solid defense that avoids the risks of 6...Kf6. If Black wishes to develop his Rook at h8, however, the King will need to move again.

7.Qxe5 d6 8.Qg3 Nf6 9.d3 Kf7 



There are 19 games in The Database with this position. White scores 53%. White's Queen puts pressure on the Kingside, even as Black prepares to castle-by-hand (something he never accomplishes).

Petasluk has had significant experience with other defensive tries by Black:

Black has reinforced his center and decides to expand on the Queenside, perhaps as a diversion. He is overlooking White's growing menace.

This encourages White to break in the center.

Black will have to give back his extra piece, and his King is in trouble.

Black is defending, but is handicapped by his undeveloped Rook at h8.

23.d4 Bd8 24.Ref4 Rf7 

He could have tried 24...Rh7, but 25.Bxg7 would have led to a series of exchanges that would have left White simply a handful of pawns ahead, e.g. 25...Rxf4 26.Bxh6+ Qg7 27.Qxg7+ Rxg7 28.Nxf4.

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

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:

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".)

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...
