top two laydown??

[viciouspenguin]

i never play these days so im not too sure if flush beats straight, etc. 4tabling 2/4 stars last night on my laptop (while camping out for the ucla - oregan bball game later today), so i have no PT, no hand history... but i have a decent idea who is fishy, who is reg. villain in hand just sat down though, complete unknown.

UTG limps, Hero with A7s in UTG+1 calls (bunch of random loose, awkward stacks behind me), CO calls, SB completes, BB (villlain) checks.

Flop A72 two diamonds.
BB checks, UTG bets $12, I make it 77 to put that bitch allin, BB pushes, UTG folds, I?
