If its a good player or someone's game u respect I reraise all in for sure from LP. A good player will be pushing any two here with that kind of stack. A bad player will blind himself to death until he gets a good hand. Probably from LMP as well. However, if your one of the next two or so after the raiser and have like 5 or 6 players to act behind you I'd fold. AT is too good to fold here and is a good chance to pick up more chips. Against certian players, the ones that understand they nee to gamble now and not later, I think reraising w/ A7,A8,A9 can all be good here as well due to their range being so big.
