OK, thanks for the advice guys. This guy kinda had a passion for calling hands down no matter what, that was why the pot sized bet on the river. I can understand toning it down to something that is more sure-fire that he will call.

Results:

Hero shows [ Th, Ac ] two pairs, aces and tens.
Button doesn't show [ 8s, 7s ] two pairs, eights and sevens.
Outcome: Hero wins $125.35
