QT is the least the hero should have considered,a bad spot to bluff.villian is either slow playing KQ,or has a Q or QT, either case with no fold equity. The hero is actually representing what the villian is holding, and what he intends to bluff fold of villian range make less sense,like AK,KJ, so he is bluffing against a single hand JT. What about 99, I don't think the villian would fold 99 either.
