Vienna Gambit Trap
The Vienna Gambit trap: 3...exf4? looks like a King's Gambit but loses time to 4.e5, and the knight has to go back to g8. Very common below 2000.
After 1.e4 e5 2.Nc3 Nf6 3.f4 the position looks like a King's Gambit, so most players take the pawn. With the knight already on f6 that is a mistake. It is one of the most common opening mistakes at club level; the table below shows how often it happens at each rating.

Knowing a trap by name is not the same as seeing it at the board. Solve positions from real games until the pattern fires by itself.
Vienna Gambit Trap
Getting there…4.e5! attacks the knight, and every forward square loses it: e4 and d5 to the knight on c3, g4 and h5 to the queen. So it has to go home: 4...Ng8 5.Nf3 d6 6.d4. White wins the f4 pawn back and is far ahead in development. The engine says less than a pawn, but in practice Black is usually run over.
