[Arcturus]

Button lost a big hand 3 hands earlier and seems to be tilting. UTG is a 33/8 LAG.

CO ($35.80)
Button ($4)
Hero ($16.95)
BB ($24.40)
UTG ($15.80)
MP ($29.55)

Preflop: Hero is SB with A[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/heart.gif[/img].
<font color="#CC3333">UTG raises to $1</font>, MP calls $1, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to $4</font>, <font color="blue">Hero....</font>

Should I raise to isolate button? If so, is it a push or would it better to raise somewhere in the $7-$8 range?
