Hickock was playing a form of poker called draw poker.Each player receives five cards. after a round of betting has the option of discarding one or more cards.Hickock must have discarded one card, leaving him with two black aces ,two black eights,without drawing a card when he was shot in the back during the game in Deadwood South Dakota
No need to answer when a right one is already posted. But I can say that Hickock started the trend with the common rule to sit and face the saloon door so something good came of it
