I have found if it,s a very large free roll you get many ALL IN,s early. But if you know the players and have a good read. Many times I find they both have the same cards. Definately Ace-x,s taking away each others OUTS.I have folded pocket 9,s for example so many times to see both players with Ace-King and neither hitting. It can be a quick triple up if you want to gamble and depending on the free roll you might want to.
