Maybe you can uses this in your games or avoid falling for it

NO

Man that was a bad move on white's part, why did he take that pawn seeing that nothing would come out of it right then.

You think people would really do the exact same moves?

Well obviously you shouldn't play this opening just for the trap

i think no opponent will play the same moves

That was a sweet trap!  People often go for that pawn just to gain a pawn.  THanks for sharing!

Everyone knows that by taking the Knights pawn with your Queen in any game and you are asking for trouble.

Anybody who plays fish move like the unwarranted Qa4+ deserve to lose her. I think white was lost as soon as he/she sit down.

The lesson is that knight pawns are often poison and always dangerous.  If you see that you can grab it, make sure you can extract the queen (or rook) quickly and cleanly.  Often times, when the pawn falls, the opponent plays the Rook over one, and skewers the piece to the first person's knight pawn, getting it back and maintaining material balance.  Sometimes, if the b7 pawn is threatened, say, black can play a3, bringing the rook onto the only escape square left for the queen to run to.  Watch out for that.
