AK, toppair massive action

[Wintergedaerm]

Ive lost my hand history, but ill talk about the hand in detail.
Effective Stacks about 100BB.
I got AKo in the small blind, 3 limpers i raise pot.
Two callers flop is
KQT rainbow. I open with a potbet about 3$ next player raises to 6$ third player in pot flat calls.
Whats my line?
The flat call makes me alert.
I folded, is this weak?

Both players are fishy but not very aggressive postflop.

Raise more than pot preflop. You are in a bad position. You want to thin the field, get it heads-up if possible. So make your raises from early position bigger instead of smaller.

Well, you're getting 6:1 direct odds on your call to the nut straight. I think I take one card off and c/f a blank turn. A minraise on the flop is often a come hand or a mediocre made hand than a monster. You are right that the flat call is dangerous. But people call too much in general anyway. I'd take the odds and call here.

Folding is really weak.
You've got TPTK with the nut straight draw. At least call and see a turn card. On the turn I would check and fold if there is some serious action.
