bottom 2 pr what to do

[azndragondf]

i don't have much read on villian, but he's possibly the type to only play his cards because i saw him blinding away for the past 3 rotations

Hero is in bb and covers everyone in a 10 player ring game
stakes are 3-100 spread with bb = 3, sb = 2, and button = 1

6 players limp to the flop and hero has 82 off

pot = $18 to flop
flop comes 982, 2 spades
sb checks, hero bets 18, fold, fold, villian min raises and has 70 behind, fold, sb folds
hero calls the 18 raise

turn 5 (no spade), hero checks, villian bets 40 with 30 behind
hero...
