From a reader:

Mr. Goldberg,
On this issue of whether or not the CBS 60 Minutes documents are forged, I cannot help drawing an analogy to poker. Anyone who has caught on to the new poker “craze” and watches Texas Hold’em tournaments on TV (or participates in tournaments themselves) is likely to come across the term “free-rolling”. This term basically describes a situation where one player has nothing to lose, but much to gain. An example would be when two players, one of whom has committed all of his chips to the pot, have essentially identical hands, let’s say they both have a pair of aces with their first two cards. The odds are overwhelmingly in favor of the two hands being a draw, and the two players splitting the pot evenly. However, when the “flop” (three cards, faced up) comes out, all three cards are spades. Now, the person who is holding the ace of spaces is free-rolling. If one of the next two cards is a spade, he wins the entire pot with a flush. Otherwise, he splits the pot. He cannot lose.
Conservatives are “free-rolling” right now with regards to the authenticity of these documents. There’s still only a relatively small chance that we’ll win the “pot”, but it’s still fun waiting to see those next two cards get turned over.
