the best possible straight that can be made given the cards on the board during a game of Holdem or Omaha
Hand 1: 7c 8c
Hand 2: 2s 3s
Board: 4h 5d 6s Kd Qs
Hand 1: has the highest possible straight (the nut straight) that can be made on the board opposed the Hand 2 who unfortunately flopped a smaller straight.
