Nassau

The Nassau is the oldest golf bet still in regular use, and the most elegant of the lot for one reason: it turns a round into three independent wagers. You are not playing eighteen holes for one prize; you are playing the front nine for one, the back nine for another, and the full eighteen for a third.

That design fixes the problem that ruins most bets: the match that dies on the 7th hole. Blow up on the front and you have lost that one, but you walk to the 10th tee with two bets still live and exactly as much to play for.

The three bets

A Nassau is three scoreboards running at once over the same shots:

Bet	Holes	How it is decided
Front nine	1 to 9	Who wins more holes from 1 to 9
Back nine	10 to 18	Who wins more holes from 10 to 18
Overall	1 to 18	Who wins more holes across the whole round

When somebody says “a $50 Nassau”, they mean $50 on each of the three: $150 if you sweep. It is the most common first-tee arithmetic mistake in golf, and it is worth saying out loud before you play.

Each of the three is played hole by hole, not by total strokes. A Nassau is match play wrapped in three layers. If you are not sure how a hole-by-hole scoreboard works, start with the Match Play guide.

How to play it, step by step

1. Set the pairings and agree what each of the three bets is worth.
2. Work out the allowance: the difference in handicaps between the two sides, allocated by stroke index.
3. Play the hole. The lowest net score wins it; a tie halves the hole and no scoreboard moves.
4. After the 9th, the front-nine bet closes and the result is called out loud. That scoreboard is finished.
5. From the 10th a fresh scoreboard starts at zero, while the overall keeps accumulating from the 1st.
6. On the 18th the back nine and the overall both close. All three settle.

The overall is NOT the sum of the front and the back. It is its own continuous scoreboard. You can lose the front by one, win the back by one and still finish the overall dead level. Three separate counts, not two and their total.

A worked example

Two players, $20 Nassau on each bet:

Segment	Holes won	Result	Payout
Front (1-9)	Ana 3, Ben 5	Ben wins 2 up	Ben +$20
Back (10-18)	Ana 4, Ben 2	Ana wins 2 up	Ana +$20
Overall (1-18)	Ana 7, Ben 7	Halved	Nobody collects

A full round and everyone goes home level. It happens more often than you would think, and it is exactly what keeps the format alive to the last green.

Presses

A press is a NEW bet opened by whoever is losing, covering the holes remaining in that segment. It is the Nassau’s escape valve and the reason the numbers can grow so fast.

• The usual trigger is being two holes down.
• The press runs alongside: the original bet stays live and the press starts from zero on the next hole.
• You can press a press. That is how you end up with five bets running on the 16th tee.
• In the automatic press version there is nothing to ask for: the moment a side goes two down, a press opens by itself.

Genuine advice: set a cap before you tee off. A $20 Nassau with unlimited automatic presses can finish on a number nobody intended to wager.

Singles and pairs

Singles Nassau. One against one. All three bets are decided by your net score against theirs, hole by hole. It is the pure Nassau and the most common between two friends.

Pairs Nassau. Two against two. Everyone plays their own ball and each hole is decided by the better net ball of each pair, exactly as in a fourball. The three bets work identically; only who supplies the score changes. If the mechanic sounds familiar, it is the same one as Best Ball.

The pairs version is more sociable and considerably less volatile: to lose a hole, both of you have to miss.

Strategy

• The front and the back are two different rounds. Lose the front by three and mentally restart on the 10th. Only the overall carries.
• Watch the overall down the stretch. It is the one people forget and the one most often given away: you can be cruising in the back-nine bet while quietly losing the overall.
• Press when your opponent is hot, not when you are. A press is for recovery, not for showing off.
• Late presses are close to a coin flip. A press opened on the 16th is decided over three holes: that is variance, not golf.
• The 9th and the 18th are effectively double-value holes, because each one closes two bets at once.

Common variations

Round robin Nassau. In a fourball, everyone plays a Nassau against each of the other three simultaneously. Nine bets over one round.

Automatic two-down presses. Presses fire the moment a side goes two down. It is the most popular version in the United States and the fastest to escalate.

Gross and net Nassau. All three bets played twice, once scratch and once with handicaps. Six bets in one round.

A 6-6-6 Nassau. Instead of two segments of nine, the round is split into three of six. That format has its own guide: Sixes.
