Dont know what to do.

very diffucult hand. Im facing an opponent that has shown on a previous hand that hell bet out an open ended straight with 3 players in a pot and when heads up on river will put a small bluff. I have kq utg+2 i limp after utg limps 2 limpers sb completes bb checks flop kt5 goes check till last limper pre flop bets 20 sb folds bb folds utg folds i raise to 60 next limper folds guy who raises 20 calls turn is 5. i check he bets 20 i call. river is 8 no flush draws he bets his last 100. I do what. This is the type of player who wont really put this much out on a big bluff hes also the type of player that will go broke 100% of the time with ak if he hits a king even if hes deep stack, hes not careless preflop but hell play marginal hands, hes also not creative. He is not thinking from the viewpoint what do i have hes only thinking what does he have.
