After the turn I put him on a hand range of A10-109 and 98 seem most likely. I would think if he flopped two pair, he would have to reraise me on the flop and if he flopped a set at least on the turn he would reraise to try to commit me. I wouldn't think A10, k10, or 10J could value bet the river though. There were alot of missed draws on the board and I think he could be making a play at it since I showed weakness.
