When White's central "Jerome pawns" are allowed to advance, and the defender has not found shelter for his King quickly enough, bad things can happen to the second player.

8...Ng6 9.O-O d6
More challenging of the center is 9...d5.
10.f4 N8e7
White may still be a piece behind, and lagging in development, but his excellent "Jerome pawn" center makes up for it. In fact, the first player is probably better.
11.f5 Nf8 12.Qh5+ Kg8
13.f6 g6
Blocking the check and kicking the Queen.
The best defense was 13...gxf6 14.Rxf6 Neg6 15.Bg5 Qd7 16.Qh6 Qg7 17.Nd2 Be6 18.Raf1 which is still better for White.
14.f7+ Kg7 15.Bh6 checkmate
