fold pf, the only hand a 14/11 3-bets that u beat is ak. assuming he always c-bets with these hands, ur folding on all overcard flops, and you're getting it in on all undercard flops, and you're only ahead on these flops when he has AK. seems like u just hit him at the right time (when he had ak). i think this is an overall -ev play against this guy.
