I don't understand what you are saying. He called an all-in while behind. What more could you ask for? You want to check-shove the turn... He'd still call- he called a push on the flop with only A's and a King kicker. I don't get it...

Are you saying that it would be better to wait for the turn, so that his odds of sucking out decrease ever so slightly? That makes no sense... yes you've got greater pot odds if he'd push a blank on the turn... but you forget the chance that that free card might be an ace or (gulp) a king (lots of reverse implied odds there). No I don't think this hand relates to the "if he'll always call a push, wait to see if he sucks out" rule. B/C a king / jack / queen (or ten as a scare card) might screw you on the turn, and then u'd be in trouble. No, no waiting on this very vulnerable, yet clearly ahead at this point, hand.
