Jerome Gambit: Is Black's King Actually Safer At d8?

?????

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) revolves around the question: Is Black's King actually safer at d8? For a while, the surprising answer seems to be Yes, but quickly - this is a 1 0 bullet game - a resounding No takes its place.

11...Ke8 

Black believes his King will be safer on d8. He plans to bring his Rook to e8 to pressure White's e-pawn.

Black pushes his attack, even as his King sits on an open file.

Following the advice, If someone attacks one of your pieces, attack one of his, a more valuable one if possible

The "Jerome pawns" are on the march.

20...Nxf5 21.Qd3+ Bd7 22.Rxf5 c6 23.Rf7 Re7 24.Bg5 



Black's King is no longer safe.

Jerome Gambit: No More Usual


The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) creates a lot of unusual positions. Playing a "reversed" Jerome Gambit is no more usual.
