2/5NL 500max game at local casino...chose this particular table of the 5 available bc it was piles deep and didn't recognize anyone except one player, whom I ended up playing this hand with:
Villain: 35-40 y/o thinking reg...very surprisingly solid (and I don't use that term loosely, especially in LLSNL). He's pretty quiet, but it's obvious he respects my game and vice versa and that we're the only two players at this table that have a clue, though we've never really talked.
Playing 8-handed...he opens UTG to 20, loose passive fish UTG1 flats, we flat T

in MP, folds to BB who calls.
Flop ($82): K

Villain bets $135....Hero ???
Hero has a total of $425 ($290 on top of river bet)...I feel like a nit just calling, but I can't think of any worse hands that he'd play this way then b/c river with. Thoughts?
