100NL KK on terrible board vs fish

[Roger Mainfield]

This was a hand by a friend of mine, we didn't know what to do on the turn, it is almost a c/f, but that is ugly...

Hero is running 15/11. the villain is a huge donkey running 41/12/2. On the turn, villian has loads of 2pair hands he will prob call with, and it's very possible he has a straight. But the pot is so big compared to stacks...

c/f turn.

Also, if he's type that will put you on AK and immediately bet flop if checked, i like a flop crai. Otherwise, I may bet 28 on flop planning to push turn.
