Seven Card Stud Low (Razz)
The lowest-ranking hand wins the pot. Aces are low only, and two aces are the lowest pair. The format is similar to seven-card stud high, except the high card (aces are low) is required to make the forced bet on the first round, and the low hand acts first on all subsequent rounds. Straights and flushes have no ranking, so the best possible hand is 5-4-3-2-A (a wheel). An open pair does not affect the betting limit.
