A trap in the King's Gambit

In the King's Knight's Gambit (1.e4 e5 2.f4 exf4 3.Nf3), 3...h6 intending 4...g5 is a respectable line. 3...f6 with the same idea doesn't work so well. This game duplicates Trap No. 133 in Irving Chernev's book Winning Chess Traps, except that in that game Black played 3...g5 and 4...f6?
