Jerome Gambit: Dangers Along The e-File

Danger!

When facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) it can be relatively easy to wander into trouble, especially if you underestimate the attacker's chances in that "refuted" opening. In the following blitz game, Black's chances collapse when he overlooks the dangers to his King along the e-file.

White's centralized Queen cannot be chased away by Black's Queen's Knight, as it resides on g6. Kicking the Queen with ...c5 is possible, but it will leave Black's d-pawn backward.

10.O-O Nxe4 

This capture is a mistake, but Black's next move compounds his troubles. He should have acknowledged the error with 10...Kd8, surrendering the Knight, hoping to play on, a pawn down.

11.Re1 Qh4

This move only works if White now captures with his Queen, as the subsequent exchange of Queens would limit White's advantage. However...

12.Rxe4+ Qxe4 13.Qxe4+ Ne7 

Down a Queen for a Rook, Black's only chance is a time forfeit - which does not happen.
