You're holding AQ in the blinds and a standard pre-flop raise is thrown out by the time it gets to you. How do you deal with this? Why?


Obviously it depends on your opponent. Against certain rocks, a fold is in order. Against maniacs, go for a reraise. What about the middle-of-the-road player? Is a call ever a good move, or is it reraise or fold?
