An ace can be used as either high or low. A flush or straight is ignored when making a low hand. Therefore the lowest hand is A 2 3 4 5. This hand is also called a “wheel. If two players have the same hand they will split the low half of the pot. This is not uncommon because many players will play any hand that consists of an Ace-deuce. When two players split the low we refer to it as getting “Quartered” as you only win a quarter of the pot.
