live game las vegas 2 5

hero bb 1000
villain sb 2000

9 handed game
just sat in the game. drunk kid on my right ( villain ) has interesting bet sizing. he is extremely loose aggressive and is getting very lucky the first orbit i was there. he was very little knowledge of the game, and it turns out hes a professional fighter.

5 way limp. i check 69off in the bb.

664 rain pot 30$

villain bets 100$. i call
a bit of pot control. my plan is to call most bets T R

turn j pot 230$
as the turn comes he looks down and checks in the dark. i check

river j pot 230$

he still doesn't look at the board from what i see and checks again. i value bet 110$. he asks the dealer "were these the two last cards to come" touching the two jacks. then he raises to 310$

what do you guys think?? bad value bet? easy bet fold? i dont think i can ever fold considering the villains line
