Jerome Gambit: An Overlooked Defense

One of the great excitements of playing the disreputable Jerome Gambit is that, beyond the historical "refutations" that are out there - and I have presented as many as I am aware of in this blog, out of a simple sense of honesty and for historical accuracy - you will sometimes have the opportunity to face new or little-played "refutations".

Sometimes they will appear as impediments.

Sometimes they will appear more as mere defenses.

You have to get past them all, anyhow. Like in the following game. 

Wall, Bill - Guest532296

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.d4 d5 

Fascinating. And why not? Isn't the proper counter in a King's pawn game the full advance of the Queen's pawn?

So, why are there only four other games with this move in my 55,650 game Database?

Oh, and condolences to Guest532296, but two of them are by his opponent in this game, Bill Wall.

Stockfish 8 prefers 7...Ne7 8.Qf3+ Kg8 9.O-O Be6 10.Nc3 Qd7 with an advantage to the second player.

8.O-O Nh6 

Development, and planning to castle-by-hand if allowed.

White has to consider the exchange of his Bishop for the Knight - whose King will the resulting open lines trouble more? 

9.Qf3+ 

White probably has a draw by repetition after 9.Qh5+ Kf8 10.Bxh6 gxh6 11.Qxh6+ Ke8, with more Queen checks to follow, but there is also the wacky 12.b4!? Bxb4 13.c3!? dxc3 14.a3!? c2!? 15.axb4 cxb1/Q 16.Qh5+ which should also lead to a draw. (Hat tip to Kenneth Mark Colby, who wrote Secrets of a Grandpatzer - that second line would be a clear "Grandpatzer draw".)

9...Kg8 10.Bxh6 gxh6 11.Nd2 Qg5 

Having chased Black's King back to g8, blocking the Rook on h8, White feels comfortable with the piece exchange. On the other hand, Black still believes that there is a possible attack on the White King - hence the Queen move.

12.Qb3+ Kg7 13.f4 Qe7 

White has hopes for his "Jerome pawns".

14.Nc4 Be6 15.f5 Bxc4 

Black was aware that putting his Bishop on e6 would make it a target, and he relied on the text move, attacking the enemy Queen, to counter any pawn push by White.

Since White's attack on Black's King will feature a Queen check from g3, Black's best defense might be 15...d3+!?, closing off the third rank. The game would remain quite complicated, although the first player still would have the advantage. 

16.f6+ 

An awkward move to meet. White's Queen will be able to escape the attack she faces (e.g. 16...Kg6 17.Qg3+ or 16...Kg8 17.Qg3+, in both cases followed by winning Black's Queen); Black's will not.

16...Kf7 17.fxe7+ Black resigned

The discovered check allows White's Queen to escape.
