I raise this. UG is right,this is a little dangerous... but I want to test his mettle. If you raise here and he folds, that sets you up if you catch a set, or just want to stone cold bluff him/check/raise him.

Make him pay for being out of position.

call and play turn is good too.... in fact it's almost certainly best to mix up both plays. Problem with a call is that you learned nothing, and he learned alot (unless you always call the c-bet...)
