Is this a cash game or a tournament? If its a tournament are the blinds big or small?
I dont like to put a lot of confidence with AQ in EP. Its a decent hand, but I dont think its that strong. If you hit an A or Q on the flop, you're still going to have to play it safe because you could either up against a better PP or a better A.
In a cash game, I'll raise it in EP but I'll play it passively if I flop an A or Q and I get a lot of action. As for tournaments, when blinds are low I'll fold it in EP. I think a lot of people over value this hand and I dont want to be in a position where i'll have to make a decision early on for my tournament life. In LP and blinds are low, i'll raise it of course. If blinds are high and worth going after, I'll raise it big PF and continue that aggression on the flop. Again, raise it in LP as well.
Just remember that AQ is a strong hand, but it can run into a lot of problems, so watch out for that.
