Anakin (AOTC) and Luke (ROTJ) vs. Darth Vader (ROTJ)

Vader held back, because Luke aknowledges somewhere (can't remember where I heard it) if Vader hadn't held back he would have beaten Luke hand's down.

I believe it is the going all out Vader myself, since after he discovered Luke had a sister, he didn't need Luke anymore.

though there is a quote from I THINK (don't quote me on the source) from the courtship of princess leia where luke says that HE thought vader was holding back. How would luke know though?
