maybe this is bad advice, maybe its not, but i treat AQ AJ and AT almost the same.

There is no such thing as a good hand, only a good flop to me.

Also don't think you have to call to the river with AA or AK if there are 5 people in the pot with 2 raisers etc.... especially in low limit games, where people call preflop raises with 3,9 and hit flushes
