I probably let this go.

My decision hinges on what CO would open-miniraise and push with. It's probably pretty easy for everyone at the table to see that SB is the easy money. I think CO is probably trapping SB when he opened, has made hero for a drawing hand or a small pair when he pushed.

Hero is getting 2.3:1 in the center for 1/2 his chips.
The center bet is slightly positive. If one player has a pair then hero is 1:2 in the hand. or ~13% above expected return => ~EV=670 X 13% => ~90.

So if the center pot is worth ~90, in the side pot I am putting up 670 to win 760 (670 + ~EV90), and need to be ~47% in the hand.
Villain must be playing AQo or worse here to make this work.
I think its too close and I let it go.
