I do think there is some merit in this thread in that you can easily fold KK if you have betting info plus physical info. PPL who act differently than "normal" pre-flop usually have AA or KK. I remember one player who threw his bet in one movement pre-flop everytime and then changed to putting the call in followed by the raise (showed KK). Another quite common tell is for a player in late position finding he has aces to look away from his cards quite quickly and look around the table but avoid eye contact.
yeah tighty does that before making a move.
This is a trumpet thread really. Its so odd how KK can be passed relatively easy online but live, never.
