Jerome Gambit: Refutation is Just the Start

One of the reasons that few chess players open a game with 1.f3 e5 2.g4 is that there is a one-move refutation - 2...Qh4 is checkmate.

For other refuted openings, however, the demands upon the defender are more onerous. Even the Jerome Gambit, which has a number of refutations, can require consistent play by Black, or the attacker will not only escape unpunished, he will win.

The following game is a good example.

Wall, Bill - Guest436030
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 7.c3 Qh4



Black does not waste time saving either of his minor pieces, but makes the same "mistake" that White often does in the Jerome Gambit - early development of his Queen.

The position, with Black's great lead in development, shows how White can see the tables turn and subject the attacker to an attack.

Before this game, The Database had 10 games with this line - all wins for Black.

(A well-timed ...Qh4 is one reason that I prefer the 6.Qh5+ variations over the 6.d4 variations; but Bill is not troubled by such things!)

8.O-O Ng4 9.h3 Be7 

Black prefers to save his Bishop, instead of withdrawing his Knight with 9...N4f6

10.hxg4 d6 11.Qb3+ Ke8 12.f3 Nf6 



White's pawn wall defense seems to scream for 12...h5!? by Black. 

13.Be3 b6 

Planning to put his Bishop on b7 to further pressure White's pawn chain and Kingside is reasonable, but slow. The move also creates deadly weaknesses on the light squares for Black, as his opponent quickly shows.

14.e5 dxe5 15.dxe5

15...Nxg4 

Black insists that he still has an attack, and is willing to give back his extra piece to prove it. Stockfish 8 is not convinced, however, and recommends, instead, 15...h5 16.g5 Nh7 17.g6 Ng5 18.Qd5 when 18...Nh3+ 19.gxh3 Qg3+ 20.Kh1 Qxh3+ 21.Kg1 Qg3+ 22.Kh1 Qh3+ etc. would lead to a draw by repetition. 

16.fxg4 Qxg4 

Compounding his error. Better was 16...Bb7, but White would still be better. Now White's counter-counter-attack wins.

17.Qf7+ Kd7 18.Qd5+ Ke8 19.Qc6+ Bd7 20.Qxa8+ Bd8 21.Nd2 Black resigned

Black is down a Rook with almost nothing to show for it.
