easy check and wait for CB from original raiser. i definitely call anything with this hand simply because the odds say he doesn't have the other A (although we know this happens so often). Orginial raiser doesn't have a big enough stack to scare me off and its always possible if he has AK or AQ that i can still hit a few of my outs (i.e. the T's or another pair hits board). You have him covered and you just flopped a set. Check and wait for the action. If everyone checks. I lead the turn for 1/2 pot.
