Most people including me - I believe habitually bet/fold this turn. A problem I've noticed with that is most aces are just calling unless they hit 2-pair. Is it ok to induce a turn bluff or semi-bluff? No read on MP3. Button is a little more aggressive than average but not totally crazy. I saw him bet a ragged flop into 5 players and then check/fold a blank turn. He's also willing to donk into the PFR with TPWK; probably less than that I'd suspect.
