AJ is definately a situational hand as is KQ or the dreaded KJ. Early in a tournament setting I won't play any of these hands and if I have a large stack I will play these hands aggresively but with caution when it comes to reraises preflop. Money game I would bring it in for a raise UTG without a doubt. I really believe the hands mentioned above need to be played based on your table image. Are you very aggresive or a tight solid player. I myself am I tight player and won't put any thought into dumping those hands. These kinds of hands are debated by every author in texas holdem literature. TJ Cloutier even makes it a point in his book on tournament holdem, co-authored by Tom McEVOY, on how he and Tom all though both conservative players, dont agree on how to play several different hands.
