Villain in this hand has been playing passive all night. He is not a regular in this game and was in today to play a "mega stack" NLHE tournament. There is one other non regular that had also played in the tournament. The table as a whole had been playing extremely loose passive with multiple pots going to the flop 6-7 way limped around (hello 2005!).
A previous hand the villain had played he had raised a limper and got to a 5 way 10 high flop that was suited in hearts. He bet the flop and turn and when an ace (non heart) hit the river he checked behind in position after 2 checks (only three to the river). His hand was 10-10 for the flopped top set. He commented that he had probably missed a bet.

At this point I am looking to hit a 3, any pair, or a heart to check raise the turn and rely on his no limit player tendencies to fold a likely overpair if I don't get there. If he checks behind on the turn I will just give up if I don't hit. The previous check behind of a non-nut hand tells me that as a no limit player he won't value bet light, but also may lay down some good hands to constant aggression.
