Nut draw in a re-raised pot

Yesterday I got an interesting call when I pushed the nutdraw in a re-raised pot.
I thin my play in the hand is totally standard, but I was kind of suprised about the call of my opponent who is a regular at this tables and with which I played a lot.

EverestPoker Game #2003266942: Table Bamako-7 - $2.00/$4.00 - No Limit Hold'em - 10:49:24 - 2007/08/29
Seat 3: BldZwtTrn ($454.20)
Seat 4: Panettiere ($382.00)
Seat 5: Misbehave ($374.50)-> 19/15/2 (1000+ hands)
Seat 6: MARC49 ($426.50)
Panettiere posts the small blind of $2.00
Misbehave posts the big blind of $4.00
The button is in seat #3

BldZwtTrn raises to $14.00
Panettiere folds
Misbehave raises to $44.00
BldZwtTrn calls $30.00
The pre-flop play here is standard, I open on the button and got re-raised by a regular who knows my range is quite big here. So I figure my AQs is good here (worse aces are in his range here) so I make the call.

Misbehave bets $48.00
BldZwtTrn raises to $200.00
I flop the nut flush draw and make a raise here which obviously commits myself here.
Misbehave raises to $330.50 and is all-in
He makes the push after running his timebank down.

Misbehave collects $749.00

So he made the call with KTs. Which is about as good as 99-QQ on this board. His explanation was that I never have a king here and although this is probably true 95% of the time it's still a bad call vs my range here.

So what is my range here....well I could offcourse have the nutflushdraw (AQs/AJs and maybe ATs), or have hit a nice combodraw with some small SC's (76s, 87s, 97s, 98s). But the most scary hands for him are offcourse AA/88 and 55 (less likely probably with <90BB stacks).

So hit pot-odds are $282/$750 (he knows I'm not folding there). So that's about 38% what he needs here vs my range to make this push +EV.

Lets see how this works out in pokerstove. I decided to let 55 out, as I'm not calling 100% here with small PP. Against this range he has about 32% which is not enough to make this call +EV or he has to think that I'm on a total bluff here a lot.

So although he thinks correctly that I probably don't have a king here this still doesn't make this a call, because he is basically flipping at best, because if have the nut draw, I have an extra ace as out and if I have a lower draw I very often have a pair here as well.
