The Nassau format is three separate bets, labeled Front/Back/Overall. Wagers are made on each of the front nine, back nine, and overall 18 holes. The Nassau is one of golf's most classic and best known wagers. Bets are often labeled as 5/5/10 meaning 5 on the front, 5 on the back and 10 on the overall.
Nassau “Presses” are bets that are added in mid-round in either an auto format (i.e. once one team gets down 2) or on a manual basis that can be opted in by a team who is behind in the tallies.
