Jerome Gambit: The Pawns, Again


Image result for free clip art pawns



In the Jerome Gambit, White may get "only" a couple of pawns in exchange for his sacrificed piece, but, if he gives his pawns a chance, they can prove very helpful in the outcome of the game. The following contest is an example.

White's calmness in the face of aggression at the end of the game is exciting, too - why become upset, if you can checkmate your opponent, first?

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8


The Jerome Defense, presented by Alonzo Wheeler Jerome in his earliest published analyses.

7.Qxe5 d6 8.Qf4+ Qf6 

This is a perfectly logical move, offering to exchange Queens to blunt White's attack; and although it does not show up in early Jerome Gambit analyses, The Database points out that it is played twice as often as 8...Nf6.

9.d3 Qxf4 10.Bxf4 Nf6 

11.Nc3 Kf7

This looks like a slight improvement over 11... a6, which was seen in vlastous - Nyanyiwa, internet 2017, (1-0, 34) 

12.h4 Rf8 13.f3 Nh5 14.Bh2 Bb4 15.g4 Nf6 16.O-O Be6 



The "Jerome pawns" already take on a menacing look, but Black is still doing fine. His problem will be finding and executing a successful defense and counter-attack.

17.Bg3 a6 18.Ne2 Rad8 19.Nf4 Rfe8 20.c3 Bc5+ 21.d4 Bb6 22.Kg2 d5 

The move ...d5 is frequently good against the Jerome Gambit (and 1.e4 e5 openings in general) but here the move gives White's Kingside ambitions encouragement. Stockfish 10 suggests the quieter 22...g6.

23.e5 Ng8 24.Nxe6 Rxe6 25.f4 c5 



The right idea, hitting back at the growing center.

26.f5 Rc6 27.e6+ Ke8 28.Be5 cxd4 



This move looks like a slip, according to Stockfish 10, which suggests, instead, 28...Kf8 29.dxc5 Bxc5 30. g5 Bd6 31.Bd4 Bc5 and a draw by repetition.

The computer is not yet impressed by the "Jerome pawns", but the problem with the text move is that White does not have to recapture at d4 - he can take the g7 pawn, instead, opening the way for the connected passed pawns that have suddenly grown fierce.

29.Bxg7 dxc3 30.bxc3 d4 

To open lines, but his King's castle has already been breached.

31.g5 dxc3 32.f6 Rd2+ 33.Kh1 Rc4 



Black's counter-attack looks scary, but White has one move at his disposal that brings home the point - by implementing his own mating attack.

34.f7+ Ke7 35.f8=Q+ Kxe6 36.Rae1+ Kd7 37.Qe8+ Kc7 38.Be5+ Black resigned

Beautiful!
