I thought this was widely known ... regarding Full Tilt Poker

I just finished playing a 9 man SnG $10+1, and 7 of the 9 players had Auto Muck Hands checked in Lobby / Options !!! so what you say? read on ...
So Whenever they muck their cards at Showdown I and anyone in the know can see them, so this gives me the advantage in that I know what hands they are likely to play ! (The cards are slightly crossed out signifying they have been mucked.) [I'm not allowed to post an image atm]

The reason for this anomaly is that the Hold 'em rules state a losing player can ask the Dealer to see the Mucked cards, in Live games rarely would anyone do such a thing as its frowned on.

Make sure you un-check this option in your FTP Lobby and then play away keeping an eye on the Last Hand window
