Hero...

i put them both on medium to high pocket pairs and i thought i could make them fold. the UTG could easily be c-betting and the MP calling with say 88-JJ.
After the UTG called its always something like 77 or AA(KK maybe?) that he isnt folding. so my plan is check/folding?

also, how often do you repop preflop against this kind of player, i would assume they call my 3 bet quite often and then im usually lost on a high card flop.
