This version of the story comes from Time-Life Books and goes like this, a pair of Seattle cardsharps were in a five-man game with the intent of skinning two of the three other men. The fifth man was a friend of sorts and they did not have their eyes set on him, plus he was unaware of the sharps intent.
At some point in the game one of the sharps rings in a cold deck, that is an identical deck of cards that have been pre-arranged so that the two victims get great starting hands but one of the sharps gets the winning hand. The fifth man wasn’t even given a pair so he was sure to drop and get out of the way.
Well, much to the sharps surprise, the fifth man not only stayed in the hand he began raising. The sharps dare not tip him off that the fix was in so they let him play along.
When all was said and done the pot had $3,600.00 ( around $79,000.00 in today’s money) in it and when the hands were shown the fifth man won the entire pot. What happened was, the sharp stacking the deck failed to pay attention to the suits and dealt the fifth man a four card straight. He drew one card which filled his straight flush and the rest is history.
