Not every Jerome Gambit (1.e4 e5 2.Nf3 Nc3 3.Bc4 Bc5 4.Bxf7+) can be a swash-buckling win for White. Often the first player must keep the game (sometimes, even the draw) in hand while looking for an opportunity to present itself (see "It's not over until the Lady sings..."). At the right moment he can strike back, like in the following game, and win the day.

Breaking in the center at the earliest moment, to facilitate an attack on the enemy King and Queen.
11...dxe5 12.Rxe5 Bd6
Black has to feel like he already has the game in the bag – always a dangerous mind-set.
