<font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises to t3600</font>, <font color="#CC3333">MP2 raises to t11399</font>, <font color="#666666">4 folds</font>, BB calls t10199, Hero ??

At this point the pot has about 29k and I've got about the same behind. Is this an insta shove??

Cold caller had appeared competent and was running 15/11 over 80ish hands. Wouldn't the fact that he just cold calls weight his range more heavily towards AA,KK?
