On the turn, there was not enough evidence for me that there was nobody who had anything and I preferred to wait for a better chance to push on another hand.

There was a good chance are my outs were dead anyway (if no-one had a king, somone must have had a Q or 9) and I really really rarely make bluffs in multiway pots without at least some semblance of a hand or a preflop raise, made or otherwise. And from the perspective of potential callers there's always the chance of enticing a call from someone who is chasing a draw themself, ordinarily this would be a good thing but with Q high it's entirely possible even a drawing hand is beating me.
