Jerome Gambit: Black is Winning, Until He Isn't

I have seen it happen (The Database says tens of thousands of times) in the Jerome Gambit: White has a blistering attack, although "objectively" the defender is better; but, then, slowly - or suddenly - Black surrenders his advantage.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Qf6 8.Rf1 

White gives up castling Kingside, to add more pressure on the enemy King.

The Database has 375 games with this position; White scores 60%; Stockfish 17.1 is skeptical, to the tune of about 2 1/2 pawns.

8...g6 9.Qh3+ Ke7 10.fxe5 

10...Qg5 

A puzzling move, turning over the advantage to White.

Instead, he had the logical 10...Qxe5.

11.Nc3 

His Bishop is now protected, so he can play d2-d4.

11...c6 12.d4 Qh5 

13.Qxh5 gxh5 14.dxc5

White is up 2 pawns, with better development.

14...b6 15.Bg5+ Ke8 16.O-O-O 

Stockfish 17.1 (32 ply) evaluates White as about a Rook's worth of material better.

Black's central pawn shield now crumbles, surrendering to the "Jerome pawns".

16...h6 17.Bh4 bxc5 18.e6 d5 19.exd5 Ne7 20.d6 

Black resigned
