I don't like the raise.

You must raise this everytime. KQs is a very strong hand against any number of opponents. If you're not raising this, you're missing out on a LOT of profit.

Therefore, I only do this raise with the NUT flush draw, or NUT double straight draw with a three suited flop, or straight flush draw. Two overcards with backdoor straight/flush draws is not strong enough, IMO, to raise here.

You're playing way too weak tight if you only raise nut draws.

If not I put him on AA, KK, two pair or set

There's absolutely no way he has AA or KK here. These hands shouldn't cross your mind. It is possible he has a set or two pair though.
