ok so you say your problem is they call a lot of 3bs and they're not folding the flop

so basically they call with tons of trash on the flop, right?
bet the turn too and they're either playing 22 for stacks unimproved or they're folding

so figure out the people who will felt really light and don't cbet/barrel them just valuetown them after you do flop a king or an ace
and the people who call the flop and fold turn without a hand
