NL50 Basic pre-flop question

[Lordy]

2nd orbit at the table so no reads yet.

Party Poker No-Limit Hold'em, $ BB (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Button ($49.40)
SB ($118.71)
BB ($23.60)
UTG ($48)
Hero ($49.95)
CO ($48.90)

Preflop: Hero is MP with Q[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/diamond.gif[/img]. SB posts a blind of $0.25.
<font color="#CC3333">UTG raises to $1</font>, <font color="#CC3333">Hero raises to $4</font>, <font color="#666666">1 fold</font>, Button calls $4, SB calls $3.75, <font color="#666666">1 fold</font>, UTG folds.

What is a "standard" range for Button ? I rarely ever see people cold-calling a 3-bet. Is TT+, AQs+, AKo a good assumption for an unknown?

SB I guess has 22+ playing for set value ?
