Big unsuited cards

[stevenbe]

S&M write often in their books that big unsuited cards do not play well multiway. You're in a small buy-in Sit & GO, first hand of the tournament. You're on the button. EVERYONE limps in. You've got AQ offsuit. Should you muck?
AJ? A-10? Strict application of their theories mandates a fold. But how can you resist getting 8:1 or 9:1 on a big Ace (assume for arguments sake you KNOW the blinds will not raise).
