Okay, let me tell you about a true high level trap, even a GM can fall for it, since, btw, a GM did fall for it, and wrote a whole page about the game in Europe Echecs. You might find the game in Chessbase or so, I'm not sure since I can't check right now. The game happened in the 90s between GM Schekatchev (spelling may vary) and GM Nataf.
White played 1.Nf3, and black wanted to play Dutch Defense. So, black played 1...-f5?
As stated GM Nataf in his comment over that game he lost: "I forgot white doesn't have to play d4..." and actually, white went for a KIA type set up with d3 instead of d4, and since, especially against a Stonewall setup, the thrust e4 is devastating (often leaving black with an isolated e pawn, among other possibilities), Schekatchev scored a brilliant win.
On my side, I think I've got somethig like 11 wins and 2 losses with white playing 1.Nf3-f5?, a majority of 1800-2200 players being involved.
So, the trap is positional, and can be a trap, when you check on your opponent's repertoire before the game, and find out they play Dutch: you might want to try 1.Nf3 instead of your usual 1.e4, d4 or c4, and see if you get the grip of why 2...-f5 is so weak...
1.Nf3 f5 was supposed to be good for white because of young Carlsen crushing Dolmatov with 2.d3, but time has changed and 1...f5 has been completely rehabilited.
It is not a trap u mention, it is a "refuted opening", which has been assessed badly since now it is considered ok for black...
The good way for black to face 2.d3 is this one :
But if Black now knows how to counter the d3 set up, then it's not so much a trap anymore.
