JJ on ATQ 2 board vs fish

It's ok to check/call the turn because you have to call if you'regetting raised on the Turn and maybe he calls Tx twice but most of the times you're betting into Ax or Qx and from Kx and Gutshots you won't get 2 Bets anyway. He looks passive by the read you've picked, though you just have a few hands but i would fold the river because i think it's unlikely that he's betting Kx and you'reblocking two jacks so he's got less Jx gutshot combos. T beats you as well now. Betting turn is certainly ok as well but you don't have to protect that much because K gives you the straight and J gives you a set.

With his VPIP he may have even coldcalled a hand like K5o or K2s J9 89 etc but you said he's got low af and he's not raising better hands and of course he's just calling A5 QJ etc but i doubt that he's bluffing Kx and 89 twice and KJ Ax Tx Qx hands dominate his range so i would rather fold.

Have you seen him doing some crazy bluff?

Never seen him bluffing. Thanks for evaluations

you're welcome at all time! Ok then you should fold!
