At the more advanced levels a lot of the stuff isn't necessarily visible as trapping necessarily. For example I can trap just by stepping in from the outside gate. I can engage the hands with mun sao and kick at the same time. They're less obvious traps. And actually what Simon described as a trap from FMA is straight out of wing chun minus a few details but read below. Yeah but I can't use A two handed clinch and punch at the same time No it has nothing to do with it being wing chun or not but about the principles of good trapping. For example I like the FMA trap in concept. It's essentially a a high line combo bong/huen sao and strike (the wing chun terminology is just an easy way to refer to the movements). But there are a few issues with it which don't follow with good trapping; he's staying equal with the opponent by not angling with his footwork, the other hand isn't even being monitored let along controlled. Now if I'm going to use that (and I do already actually) when you circle the hand out you strike in with the other hand. Usually the opponent blocks or is already striking with the other hand so you can control that hand out of the way.
