Has been posted on other message boards/forums. During play you could look in the hh and see what mucked cards were folded before showdown. Let me explain, you fold A4 on the flop and if you checked in the hand history you would see that A4 was folded by another player. You are not supposed to be able to see oppoents hole cards unless it goes to showdown or he/she elects to fold and show cards. This let's you see how players play hands and narow hand ranges down...ap was informed and corrected the glitch...god knows how long this went on and it has been confirmed by some big names in poker.
