I can't say that Doyle, Amarillo and Sailor never colluded in a poker game, but I can say that they didn't always play in the same game - but they knew each others moves and styles because they discussed their play with each other after games. What better way to learn than to have two friends that also play a good game and then re-hash everything you've seen for the last 20 hours? I'm jealous.
Also, since most of the games they were playin in during the late 1950's and early '60's were held at "wealthy" rancher and oil men's homes (where you attended by invitation only), it is doubtful that the other players (like Johnny Moss, Jack Straus, Bob Hooks, Puggy Pearson etc.) would have allowed - or not seen any collusion going on. Nobody knows for sure, but I would bet against serious going on.
