Full explanation — The Nuts
The nuts, or 'having the nut hand,' describes the best possible five-card poker hand that can be made with the community cards currently on the board. When you hold the nuts, it is impossible for any opponent to have a better hand, guaranteeing you at least a chop of the pot, if not the entire pot. Identifying the nuts on any given street is crucial for aggressive betting, as you want to extract maximum value. Players often refer to 'nut draws' when they have the potential to make the nuts if their draw hits.
