I would have thrown out a $4-$5 river bet, he's not checking the river after you just checked the turn if indeed he does have a ten, he would want to try to cash in on it and not just pray you bet the river so he could raise. It would have been his turn to value bet the river if he thought he was ahead, just my opinion. What did he have, Jacks-Kings or something? The flop raise was a little much I think, but nothing I should really be nit-picking I guess.
