looks to me like he had something like 89 in the BB. Tried to semi-bluff the flop, and wanted to draw out on river calling your turn bet. I think if he had 2 pair, like J-2,10-2 which are very possible in the BB or J10 then he would have come over top because the aggressor and lag that he is. Same with a set. I think you missed some value with pot sized bet on river, becuase i cant see what type of hand he would call that raise with that wont beat you. I would check and hope he tries to steal the pot because i know if i lead he's going to lay down his hand (if i put him on 89) and i miss a bet.
