Indeed, calling KQo (even from BU) it quite a difficult situation as most likely you'll flop TPGK and be beat by TPTK. If villain had his PFR up to 13 and it was HU I would call as he would pay me off on Q high flop if he had QJ/QT.
As played:
- turn: I would be tempted to b/f turn. If villain calls he would most often checks river and we would check behind. If he bets river we would easily fold.
- river: fold. you only beat a bluff
