I don't have a specific read on CO, but he is a low stakes winning player. My main question is what to do with these stack sizes? I've only been at this table a few orbits.

Hero (t9070)
SB (t3930)
BB (t12100)
UTG (t13660)
UTG+1 (t10017)
MP1 (t10995)
MP2 (t13837)
MP3 (t8395)
CO (t6705)

Preflop: Hero is Button with A[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/diamond.gif[/img].

Calling is fine as well.

If hes tight a fold isnt terrible

I push this unless CO is playing very tight.
