The gammon save is one of the most important — and most frequently neglected — skills in competitive backgammon. When you’re losing a game, accepting a plain 1-point loss is often far better than the catastrophic 2-point loss of a gammon. Knowing when and how to save the gammon can be the difference between winning and losing a match. This guide explains everything.
Key Takeaways
- A gammon (losing without bearing off any checkers) costs 2 points in match play instead of 1
- A gammon save converts that 2-point loss into a 1-point loss by getting at least one checker off before losing
- The correct decision depends on the match score — at some scores, saving the gammon is more valuable than trying to win
- Gammon risk also affects cube decisions: high gammon risk makes positions harder to take
- The Jacoby Rule makes gammon saves irrelevant in money games where no cube has been offered
- Use match equity tables to calculate when a gammon save is worth sacrificing winning chances
What Is a Gammon?
A gammon occurs when one player bears off all 15 checkers before the opponent has borne off even a single checker. In match play, the winner scores 2 points instead of 1.
A backgammon is even more severe — the loser still has a checker on the bar or in the opponent’s home board when the winner finishes bearing off. This scores 3 points.
For full definitions, see the backgammon gammon guide.
What Is a Gammon Save?
A gammon save is any sequence of plays made specifically to ensure you bear off at least one checker before losing the game — converting a gammon (2-point loss) into a plain loss (1-point loss).
The term is used in match play. In a money game context, the equivalent concern is called gammon risk management.
Simple Example
You are losing badly. Your opponent is in the process of bearing off. You have 4 checkers in your home board and 2 still stuck outside. Rather than trying to bring the outside checkers home efficiently, a gammon save might mean moving a home board checker off immediately — even sub-optimally — to guarantee you get at least one checker off before losing.
Why Gammon Saves Matter: Match Equity
The value of a gammon save is not constant — it depends entirely on the match score. Match equity tells you your probability of winning the overall match from any given score.
When a Gammon Save Is Critical
Consider a match to 5 points where the score is 4–3 in your opponent’s favour (they lead):
- If you lose a plain game: Score becomes 4–4. You still have good winning chances.
- If you lose a gammon: Score becomes 4–5 (or 6–3 depending on direction). Match over, or near over.
At such a score, the difference between losing 1 and losing 2 points is enormous. The gammon save is absolutely the priority — even if it costs you significant winning chances.
When a Gammon Save Is Less Important
Consider a match to 7 points where the score is 1–1:
- If you lose a plain game: Score becomes 2–1.
- If you lose a gammon: Score becomes 3–1.
The difference is real but small — match equity tables show only a modest difference. You shouldn’t sacrifice major winning chances just to save the gammon at this score.
Rule of thumb: The closer the score is to match point (for either player), the more valuable the gammon save typically is.
How to Execute a Gammon Save
1. Identify the Threat Early
Don’t wait until your opponent is bearing off to think about gammons. Once you realise you’re likely losing, assess:
- How many checkers do you have outside your home board?
- Is your opponent likely to bear off before you get a checker off?
- What is the match score — how much does a gammon cost you?
2. Prioritise Getting One Checker Off
Once you decide the gammon save is correct, your first priority is getting one checker off the board. Until that happens, every play should be evaluated primarily on whether it helps achieve this goal.
- Move home board checkers toward bearing off rather than moving outer checkers
- Accept an inefficient home board play if it gets a checker off faster
- Sometimes it’s correct to bear off from a high point (leaving a gap) rather than playing an outside checker home
3. Balance Winning Chances vs. Gammon Save
This is the hardest part. Sometimes the play that saves the gammon also reduces your winning chances. You must weigh:
- Equity if you win (match equity with 1 more point for you)
- Equity if you lose plain game (match equity with 1 more point for opponent)
- Equity if you lose gammon (match equity with 2 more points for opponent)
Using a match equity table or a reference chart, calculate whether the gammon save is worth the winning chance cost.
Gammon Risk and the Doubling Cube
Gammon risk doesn’t only matter when you’re losing — it affects cube decisions throughout the game.
High Gammon Risk Makes Positions Harder to Take
When your opponent has significant gammon chances against you, a take is riskier:
- You are not just risking a 1-point loss (at the current cube level)
- You are risking a 2-point loss (or more) if they gammon you
The effective take point shifts: you need better winning chances to justify a take when gammon risk is high.
For the full cube framework, see backgammon doubling cube strategy.
Using Gammon Threat to Double
Conversely, if you have significant gammon chances against your opponent, this strengthens your double:
- A position that would be a weak double without gammons becomes a clear double with gammon threats
- This is why many doubles in backgammon are correct primarily because of gammon pressure, not pure racing advantage
Gammon Save vs. Playing to Win
Positions Where Gammon Save Is Correct
- Match score where being gammoned is far more costly than losing a plain game
- You are far behind in the race and cannot realistically win anyway
- Your winning chances are under ~10% — trading them for a guaranteed gammon save is worthwhile
Positions Where You Should Play to Win
- Match score where a gammon is only marginally worse than a plain loss
- You still have reasonable winning chances (>15–20%)
- The play that saves the gammon significantly reduces your winning chances
Never automatically play for the gammon save. Always calculate or estimate the equity difference first.
The Jacoby Rule Exception
Under the Jacoby Rule (used in many money games), gammons and backgammons only count if the doubling cube has been turned at least once. If no cube has been offered, a gammon scores only 1 point — the same as a plain loss.
In this situation, the gammon save becomes irrelevant: there’s nothing extra to save. This is one reason the Jacoby Rule is popular in casual money games — it eliminates late-game gammon save complications.
In tournament match play, the Jacoby Rule is never used. Gammons always count their full value.
Gammon Save in Bearing Off
The bearing-off phase is where most gammon save decisions occur. Key principles:
Bear Off Even Inefficiently
If you risk being gammoned, it is often correct to bear off a checker from a non-optimal point rather than moving an outside checker to a more efficient position. The priority is getting that first checker off.
Spreading vs. Clustering
In normal bearing off, you want to spread checkers evenly. In a gammon save situation, you prioritise getting checkers off quickly over spreading — even at the cost of leaving gaps.
The One-Checker Rule
Once you have borne off even a single checker, the gammon is saved. From that point, you can resume evaluating plays normally — the extraordinary gammon save priority disappears.
Backgammon Save: The Extreme Case
A backgammon costs 3 points. Avoiding a backgammon — getting a checker off or getting your checker off the bar or out of the opponent’s home board — is even more critical than saving a gammon. The same principles apply but with higher urgency:
- Move bar checkers as fast as possible to avoid backgammon at the very start of bearing off
- Getting out of the opponent’s home board is a priority in the late middle game
Summary
The gammon save is a critical match play skill:
- A gammon costs 2 points in match play instead of 1 — the difference matters enormously at certain scores
- Gammon save = ensuring you get at least one checker off before losing
- Correct play depends on the match score — use match equity to evaluate
- Gammon risk affects cube decisions throughout the game — not just at the end
- In money games with the Jacoby Rule, gammon saves are irrelevant (no cube = no gammon value)
Combine gammon save awareness with strong match play strategy and cube handling for a complete competitive game.
