River Overbet into a Tricky player (4 handed)

Reads: Villain raises fairly liberally pre-flop, and has been taking down almost every pot when he does. Post-flop, he is a tricky, but thinking TAGish player.

Seat 0 is at seat 0 with $91.50.
Hero is at seat 1 with $90.60.
Villain is at seat 3 with $95.80.
Seat 4 is at seat 4 with $34.70 (sitting out).
Seat 5 is at seat 5 with $17.10.
The button is at seat 5.

Seat 0 posts the small blind of $.50.
Hero posts the big blind of $1.
