Here are some other ways I would have played this hand.

Instance #1
Flop - Check/Call.
Turn - Check/Call. (Check/Raise here is a nice move. Since you're after him, a minraise wouldn't be a bad idea.)
River - Bet/Raise

#1 is a little easier to suspect trip/quad threes for more advanced players.

Instance #2 (I like this better)
Flop - MinRaise.
Turn - Check/Call (To get him thinking you were blowin' smoke)
River - Bet/Raise however you like.

#2 will have em confused a little more, but you risk driving out action early. I prefer this method even though you push action out sometimes on the flop, because you usually get some more money in on the turn.

Nice hand btw, quads is the nutz.
