($16) KQs versus action

[11t]

No reads on any of the players. Preflop, I am not folding to a minbet. I called the flop because KJ/KT are probably firing out that bet but on the turn I convinced myself he had flopped a set. AK is a possibility I suppose but I figured AK is most likely re-raising preflop to get the pot HU.

Should I re-raise the flop?

I felt like I was folding the best hand here a way too high % of the time since KJ could "value bet" this brick turn as well or he could have turned a flushdraw with kxs.
