Was my play correct?
CO stats 81/54/1.68/51 over 92 hands
BU stats 28/14/1.50/50 over 43 hands
BU has passive tendencies. problem is that when he knows that CO is unreasonable, he might even raise with any PP but i don't expect BU to raise many worse hands. i rather expect him to call down with pocketpair. he's in a comfortable position, being IP and he doesn't actually have a big edge with a pocketpair and equitywise he could just call and thus i think he has the King and is even raising the K on the turn as this donkbet by that guy represents nothing. 
i like the fold but certainly it's uncertain whether you may have folded the better hand.
