Right, we need more info OP. How many runners, how many left? If its a SNG with 6 players left its much different to early stages of an MTT.
How have the other guys been playing? How did he get down to 600 chips? How did you get to your stack level? Table image? etc etc etc
Its folded around to the CO, he jams his 10bb, he could be doing that with K3+, the button is the one you may want to worry about, if he jams here, he's trying to isolate, but if he loses this hes left with 10bb from his 20bb stack. Youre getting 955+645+60+30=1690 or about 1.8/1, so if you call with more than 35% equity, its at minimum a break even call.
assigning CO a: 77+,A7s+,K9s+,QTs+,JTs,ATo+,KTo+,QJo (15%)
and the button a then: 88+,ATs+,KQs,AQo+ (6%)
and you exactly AdKh
You have 35.49% equity in this hand.. Its breakeven.
Its a little different because of the side pots though, so if you think the button is weaker, call more often, if you think the button is stronger, call less often...
