Nut-Nut (poker)
In any high-low game, having both the best possible low and
high. In a community card game, this means the best possible
based on the cards showing. For example, in Omaha, with 3-4-5-K-Q
of mixed suits (no three cards of the same suit) on the board,
the nut low would be A-2 and the nut high 6-7, so a player having
A-2-6-7 would have nut-nut. With A-2-3-3-K on the board, a player
holding nut-nut would have 3-3-4-5, four treys for high and
a wheel for low. The term is also sometimes more loosely used
for hands that are nut low, near-nut (but obviously unbeaten)
high.
