This one is very close. Each hand is an Eight low. However, Hand A 8-5-4-3-A narrowly beats hand B 8-5-4-3-2. The first four cards are the same, but the Ace in hand A beats the Deuce in hand B.
Some players find it useful to always think of the low board in terms of ordinary numbers. Once the cards are arranged from highest to lowest, the smallest number wins. For example, they would think of 8-5-4-3-A as 'eighty-five thousand, four hundred and thirty-one' (85,431). This hand therefore is therefore lower than 8-5-4-3-2 or 'eighty-five thousand, four hundred and thirty-two' (85,432).
Here we have a split for the low half of the pot. Both hands consist of exactly the same Seven low, 7-6-3-2-A.
