I iso-raise in late position 2 limpers w/ KT to 700 (blinds 75/150).
villain in BB calls, limpers call.
flop: J-T-3 (rainbow).
checked to me, I c-bet 350.
only villain calls.
Turn: J. goes check/check.
river: 9. villain inta-bets 1/2 pot.

reads on villain: loose-aggro-donk, insta-bets a lot.

when he insta-bets, I think he's kinda polarized: AT, QT, and T's with worse kicker than mine probably don't insta-bet instead. random J's of course insta-bet (he doesnt' have to have a J, especially with card removal). KQ got there.random gut-shot AQ want to bluff.

fold or call?
