Should I maybe have slowed down on the turn fearing the worst? I hate to put people on the hands that scare you the most though in situations like this where the villain has not pushed back at all. I know my bets are too light on flop and turn, but I was scared of the K, which I assume shouldn't have affected the amounts of my bets though. Let's say I thought there was a 75% chance that villain had a K by the river, would his short stack justify a call at all? Wondering how others would have played it.
