TPGK OOP @20NL

Villain's 3rd hand so no reads. Villain tanked hard on the turn. By the way, I'm not dealer, I'm CO. Cake's HH is messed up.

well if he tanked hard, I don't see any value in potting the river
either bet small or check

check, call a small bet.
If you bet then it's unlikely that he will be calling much that you beat, nor folding much that beats you.

bet/fold a small amount against a passive player/station

check/call works too
