Jerome Gambit: Don't Slip, Defender

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) does not win by force - it requires help from the defender. 

Sometimes that help comes in the form of a "slip" - something always possible in a blitz game.

Black's defense is turning into a counterattack. He has an extra piece for a pawn, and his two Bishops are powerful.

12.Qh4+ Kd6 

Ooops.

13.Bf4 Black resigned

Black can console himself that he had "won" the analysis - objectively, he was better - while all White has is a win.
