Villain isn't a complete idiot but he seems a little passive and overvalues his hands a little too much from previous history. I highly doubt he has me on this flop as he likes to call a lot of my cbets with or without a hand, sometimes he flosts sometimes he just checks it down with nothing. Effective stack size is almost 350 BB which isn't great for TPTK though even on this board. I thought a Cib might be good here as he'll stay in with nothing or hands that I beat and shove with sets.

i dont cib really at all

you raised it up from mp here, and he raises ur flop cbet. He likes to call down w/ crap and weak pairs which you say he overvalues, and you have no proof that hes using position like a weapon by trying to raise ur cbets. I think the cib is bad here, what is ur plan on the turn, if its a club or a blank and he pots it? Are u gonna cib and check it to him or lead again and stack? I just wudnt play the hand like this given villains passive tendencies. I just call the min raise, fold to most bets on a club turn, call any bet 2/3psb or less on blank. If the river blanks and he fires again, then its up to you, im prob folding tho. Its just top pair vs a passive oppponent.
