You still have enough equity if its just kk,AA and AK. If its Kk+ you could still call with implied odds added with your equity. You only need 25% equity to make a call profitable.
This is a call with the dead money from CO ... and they may call as well to add into the pot. If you whiff Flop and she leads out then you can consider folding if you dont even have any backdoor draws.
How does the raise compare to previous from SB? She should be protecting better ... GL
Agree, must call. Assuming CO folds you are still getting $15:$65 or 1:4.3 odds with another 4-6:1 implied. Not hugely EV, but enough to justify the call. Especially if she will fold KK on an A high flop
This is actually a gross spot. pocket pairs make up a large part of CO's range so you don't want to be setmining to try to stack him. Unless you flop a jack you'll have no idea where you're at OTF whether or not overcards fall. Yes, we only need 25% equity but this is a ROI situation.
Raising can't be correct either unless you think she's tilting or she has TT/AQ+ in her range. So I guess it's your choice between calling to setmine/ high variance postflop situation or just folding like you did.
