Tough flop decision

[durron597]

Stars WSOP round 1 400 FPP satellite. I definitely had an image where my flop bet could be percieved as an attempt to just take the pot down. I also was certain that my opponent was capable of making a move on me - and that he had a brain on his head because he raised UTG+1 a few hands ago and folded to two allins - says he had AT. Comments on all three decision points appreciated, note that I am getting 2.5:1 to call his push.

Note that my stack is *not* large enough to fold into a seat (9 seats, something like twentyish players left). My current stacksize is a low final table stack size.
