I really didn't think he had a seven here, and (conveniently?) put him on a lower ace that might have picked up a flush draw. At the time, I instantly pushed and thought it was obvious, but afterwards I was wondering if I overplayed TPTK here. Does anyone play it differently? Basically, I knew he would call my push, but I thought AQ, AJ, and even a horribly played A10 or KK would call as well as hands that beat me, e.g. A7, 22, 77 and AA (the last two being super-unlikely).

Nah, this is fine. You'll get paid off by worse aces a lot.

is impossible.. the A [img]/images/graemlins/club.gif[/img] is there with two clubs, he cannot have a lower ace with a flush draw.
