I'm sorry if something along these lines has been addressed before but what are chances that no Ace, King, or Queen lands on the flop? A lot of people have told me not to raise with jacks pre-flop but I always made a decent raise with them espeicially in late position. I figure with less hands seeing the flop and maybe even one overcard I could still take down the pot. What are the lowest pocket pair most of you would raise with in a cash game or early in a tournament?
