Pretty early on. SB is obvious donk, playing garbage oop. No real reads on anyone else yet.

Pre-flop: (8 players) Hero is BB with K[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/club.gif[/img]
<font color="#cc0000">UTG raises to t210</font>, 3 folds, CO calls t210 <font color="aaaaaa">(pot was t300)</font>, Button folds, <font color="#cc0000">SB raises all-in t570</font>, <font color="#cc0000">Hero??

At this level is it OK to shove?

I need help in this situation, I lean towards a fold, but is that too weak?
