Dutching is one of the most practical techniques in a serious bettor's toolkit. Instead of backing a single outcome, you spread your stake across two or more selections in the same market so that you win the same profit regardless of which one comes in. If you have ever felt torn between two likely winners, Dutching is the structured way to act on that instinct.
What Is Dutching?
The term dates back to the 1930s and legendary gambler Arthur "Dutch" Schultz, who reportedly used the method at horse tracks. The core idea is straightforward: you calculate the exact stake for each selection so that every winning outcome returns the same net profit.
Dutching differs from simply placing multiple bets at random. Without the correct stake split, one winning outcome may return far more than another, leaving you exposed to variance you did not intend. Dutching eliminates that imbalance by design.
The Dutching Formula
For a set of n selections with decimal odds O₁, O₂, … Oₙ, the individual stake on selection i is:
Stakeᵢ = Total Stake × (1/Oᵢ) / Σ(1/Oⱼ)
Where Σ(1/Oⱼ) is the sum of the inverse odds for every selection you are including.
The combined implied probability of your selections is simply:
Combined Probability = Σ(1/Oⱼ)
If this value is less than 1.00, your Dutching combination has a theoretical edge — you are getting more than 100% of your money back across the covered outcomes.
Quick Mental Check
Before running the numbers, add up the implied probabilities of each selection you want to include. If the total exceeds 100%, you are guaranteed a loss on every outcome. If it stays below 100%, there is a potential profit window.
Worked Example
Suppose a tennis match has three possible set-score outcomes you like, priced at different bookmakers after line shopping:
| Selection | Decimal Odds | Implied Probability |
|---|---|---|
| Player A wins 2-0 | 3.20 | 31.25% |
| Player A wins 2-1 | 4.00 | 25.00% |
| Player B wins 2-1 | 4.50 | 22.22% |
Combined implied probability: 31.25% + 25.00% + 22.22% = 78.47%
Since 78.47% is well below 100%, this combination could be profitable. With a total stake of €100:
- Stake on A wins 2-0: €100 × (1/3.20) / (1/3.20 + 1/4.00 + 1/4.50) = €100 × 0.3125 / 0.7847 = €39.83
- Stake on A wins 2-1: €100 × 0.2500 / 0.7847 = €31.86
- Stake on B wins 2-1: €100 × 0.2222 / 0.7847 = €28.31
No matter which of the three outcomes wins, the return is approximately €127.47, yielding a profit of around €27.47 on the €100 invested. If none of the three outcomes wins, you lose the full €100.

When Should You Use Dutching?
1. Exploiting Soft Lines Across Bookmakers
The most common use case is when line shopping reveals that two or more outcomes are overpriced relative to their true probability. By Dutching across bookmakers, you capture the combined value. Use the calculator odds converter to compare odds in a consistent format before deciding.
2. Horse Racing and Multi-Runner Markets
Markets with many runners (horse racing, golf outrights, MMA cards) often have inefficiencies in the less popular selections. Dutching two or three runners whose combined implied probability is low can be more reliable than singling out one long shot.
3. Reducing Variance on Value Bets
If your model identifies several +EV selections in the same event, Dutching them reduces the volatility of your session while preserving positive expected value. Check each selection with the calculator ev before combining them.
4. In-Play Betting
Odds shift rapidly during live events. If you spot two outcomes both drifting to generous prices due to market overreaction, a quick Dutch lets you lock in value before the lines correct.
Dutching vs Traditional Hedging
People sometimes confuse Dutching with hedging, but they serve different purposes:
| Aspect | Dutching | Hedging |
|---|---|---|
| Timing | All bets placed at the same time | Second bet placed after the first, often mid-event |
| Goal | Equal profit on any covered outcome from the start | Lock in or protect profit from an existing position |
| Mindset | Proactive value capture | Reactive risk management |
| Market coverage | Typically covers a subset of outcomes | Usually covers the opposite outcome |
Dutching is an offensive strategy — you are seeking profit. Hedging is defensive — you are protecting profit or limiting loss.
Advantages of Dutching
- Lower variance: Covering multiple outcomes smooths your results session to session.
- Captures scattered value: When no single outcome is a standout bet, Dutching lets you exploit the combined edge.
- Discipline: The formula forces exact stake sizing, removing the temptation to overweight a favourite pick.
- Bookmaker diversification: Placing bets across multiple bookmakers is natural with Dutching, which helps manage account health.
Risks and Limitations
- Uncovered outcomes: Dutching does not cover every result. If none of your selections wins, you lose the entire stake.
- Margin erosion: If the combined implied probability is too close to 100%, the bookmaker margin eats your edge. Always check the total implied probability before committing.
- Execution risk: Odds can shift between placing the first and last leg. Use bookmaker "lock" features or bet quickly to minimise slippage.
- Account restrictions: Consistently sharp betting patterns, including systematic Dutching, may attract bookmaker attention over time.
Step-by-Step: How to Dutch a Bet
- Identify the event and market you want to target.
- Line shop across bookmakers using the calculator odds converter to find the best available odds for each selection.
- Check combined implied probability. If it is at or above 100%, there is no edge — walk away.
- Evaluate expected value for each selection with the calculator ev to confirm you are not Dutching neutral or negative EV lines.
- Enter your odds and total stake into the calculator dutching to get the exact split.
- Place all legs as quickly as possible to avoid odds movement.
- Record the bets in your tracker and review the outcome.
Common Mistakes to Avoid
- Dutching correlated outcomes: If your selections are not mutually exclusive (e.g., "Over 2.5 goals" and "Both Teams to Score"), the formula breaks down because both can win simultaneously, meaning you overpay in stakes.
- Ignoring the vig: Always check the no-vig probabilities, not just the raw odds. A Dutching combination that looks profitable against published odds may be neutral once the margin is stripped out.
- Chasing coverage: Do not add weak selections just to cover more outcomes. Every selection should have standalone value or at least a neutral expected value. Quality over quantity.
Conclusion
Dutching is a structured, mathematical approach to multi-selection betting that removes guesswork from stake allocation. When combined with disciplined line shopping and expected value analysis, it becomes a powerful method for capturing value that would otherwise be left on the table.
