Fold bottom set at $50nl?

[mittman84]

Button is ~16/12 after ~100 hands, no notes, nothing out of the ordinary, if anything tight. Sb is a huge fish.

Button has $60, SB has $73, I have both covered.
3 fold around to Button, He opens to $2, SB calls, I call with 9[img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/spade.gif[/img] .

Flop comes: T[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/club.gif[/img] ($6)

Sb leads for $1.5
I raise to $8
Button re-raises to $22
SB folds
$14 more back to me.

I think that QQ and TT are a pretty big part of his range, but he could also be doing it with KJ which I have 7 outs, and AJ[img]/images/graemlins/club.gif[/img]s or something similar. He has been playing extreamly straight forward so far. Thoughts?
