JJJ, worst possible river

[bnorthro]

Villian in this hand seems pretty solid. He's 23/20/2 over 70 hands, but he was playing much tighter for the first 2/3 of the session (maybe bad cards, it's an aggressive table).He hadn't been in many hands, He played Q10o in a huge family pot (capped 5 ways) to the river on a 10 hi board, he had KK vs my JJ earlier.

Final Pot: 16.50 BB

The river was probably a bit excessive. Is this a bet/call, check/call line on the river with an unlikely str8 making it? I found it really hard to believe he could/would play A10 this way. I think his much more likely holding would be something like AQ, KQ, AK (probably not with the flop action). QQ, KK, and AA are possible, but he would have capped those.

Just checking some of my lines (I've been playing on PokerRoom for the last 12k hans, so no converter -&gt; no hand posts).

Thanks.
