Donk off or no?

Raises turn/folds to threebet? my qustions are these
1) if he calls / checks do you bet for value? If not , why not?
2)what hands that are even remotely legitimate hands in that spot are you beating?
3) What percentage of hands that beat you in that spot do not justify a threebet on his part?

Ahh- shams line is the one i took. called down like a donk, i was shown a K,,obv. I IMed the hand to piers, and piers ALLEGED he'd muckit. I was like, a kuso's penislength away from muckin it on the turn when that 8 paired, but icalled like a donk figuring i beat like....yeah im not shure exactly whati beat,which is why i shouldnt havecalled.
