Jerome Gambit: Keep On Keeping On.

A strong defense against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) requires White to keep the pressure on, and to keep on keeping on - until an opportunity arises to resolve the game as a win for the first player.

With the plan to bring the Rook to the f-file to harass the enemy Queen.

Black's great lead in piece development means that White has to be careful.

To exchange off White's strongest piece, which will get little rest.

Black's two Bishops out-shine White's Knight. 

His problem is his unsafe King - which would have been better protected by 18...Qd6. 

White sees his opportunity and quickly takes advantage of it.
