Strong hand facing river overbet

[aggie]

Villian seems fairly loose but decent. He's 29/13 after 221 hand. We played a very similar hand to the one below where i checked behind on the turn with a strong hand, he overbet the river and i paid him off (he had a set)....That's all i know about him though.
