Dutching on Betfair: Cover Multiple Outcomes

What Is Dutching?

Dutching is the practice of dividing your stake across multiple selections in the same market so that whichever one wins, your return is identical. Named after Arthur "Dutchy" Schultz — the prohibition-era racetrack operator who reputedly used the technique — dutching has been part of professional gambling for nearly a century.

On Betfair Exchange, dutching usually means backing two to four selections in a horse race or football market. You calculate the stakes so that each winning outcome pays out the same. The selections you don't back become your collective "loss" outcome — but if you've identified a small enough subset, the combined probability of winning is high.

If you haven't read what is Betfair trading and green up explained yet, do that first. Dutching is essentially green-up applied across multiple selections.

Why Dutch on the Exchange?

Three legitimate reasons to dutch on Betfair:

• You believe two or three selections are systematically underpriced: Dutching lets you back all of them at the right combined stake. If your view on probabilities is correct and the price aggregate is wrong, dutching captures the edge.
• You want defined-risk exposure to a market trend: If you think a horse-racing favourite is vulnerable but you don't know which outsider will win, dutching three outsiders captures upside if any of them does — without picking one and being wrong.
• You're correcting an in-running over-round: Sometimes during in-play horse racing or tennis the market over-rounds (sum of implied probabilities exceeds 100% by a meaningful margin). Dutching the right combinations can produce arbitrage in seconds — though this is increasingly rare on top markets.

Dutching is not a system that turns losers into winners. If your selection picks are no better than random, dutching simply distributes the loss. The edge must come from your view of probability, not from the dutching mechanic itself.

The Dutching Formula

To dutch a fixed total stake (S) across N selections at odds O₁, O₂, … Oₙ for equal profit on every winning outcome:

P is the "book percentage" of your dutched subset. If P < 1 you have a positive expected outcome on the dutched portion (whichever wins, you're up). If P > 1, the market is over-round — your dutched stakes are losing money even before the unbacked selections win.

The Betfair Square dutching calculator automates all this. Punch in the selections and prices; it returns stakes for each.

Worked Example — Horse Racing Dutch

Dutching Football Markets

Dutching works on any football market with multiple selections — most commonly:

• Match Odds: dutching home + draw, or away + draw, lets you cover "not the favourite winning". Useful when a heavy favourite looks vulnerable.
• Correct Score: dutching three or four likely scorelines (1-0, 2-0, 2-1) gives broad exposure to a "home win, low-scoring" thesis.
• First Goalscorer: dutching the two or three most likely scorers when you have a strong view on the player out-performing market.

Dutching Tennis

Tennis offers fewer dutching opportunities because match-odds is two-runner — you back one, lay the other, no need for dutching. Where tennis dutching applies is in set-betting or correct-score markets where multiple set scores have similar probabilities. Read our tennis trading guide for the broader context.

Practical example: if you think a match will go to three sets but you don't know who'll win, dutching the 2-1 wins for both players locks in profit on a three-set outcome. The maths is the same — implied probabilities, scaled stakes, equal return.

Lay Dutching (Reverse)

Lay dutching is the inverse: you lay multiple selections at small stakes so that you profit if any one of the unlay'd selections wins. Useful when you think the market favourite group is overvalued and one of the longer-priced selections is likely to upset.

When Dutching Makes Sense

• You have a probability view, not a "single horse" view: If you think the favourite is vulnerable but can't identify the specific winner, dutching the next two or three is logical.
• The combined book percentage is favourable: Sum 1/odds for your dutched selections. If P > 0.85 (typical for a top-three subset), the maths is tight — you need genuine edge. If P < 0.50 you're capturing only marginal probability.
• Liquidity is sufficient on every selection: Dutching 5 horses at £20 each means matching 5 separate orders. If any one fails to match, your dutch is incomplete and the maths breaks.
• You're using software with multi-selection bet placement: Bet Angel and Geeks Toy both support one-click multi-runner dutch entry. Manual dutching is slower and error-prone.
• You've factored in commission per selection: Each winning leg is taxed at the market's commission rate. Build commission into the dutching calculator before deciding whether the trade has positive EV.

Risks and Common Mistakes

Five common dutching mistakes:

1. Dutching too many selections: Dutching 6 horses in a 14-runner race covers 95%+ of the field. Combined book percentage approaches 1.0. After commission, almost certainly a losing strategy.
2. Ignoring commission: Each winning dutched leg pays commission on the gross winnings. With 5% football commission, dutching erodes profit fast. UK racing's 2% rate is more dutching-friendly.
3. Dutching at fixed odds without checking match status: If one leg matches at a worse price than displayed, the "equal profit" structure is broken. Always check actual matched prices before resting easy.
4. Confusing dutching with hedging: Dutching covers multiple selections in a market. Hedging closes a single position. They're different operations, often used together but not interchangeable.
5. Using dutching as risk-management substitute: Dutching does not reduce bankroll risk if your overall stake is the same. Spreading £200 across three selections still risks £200 if all three lose. See bankroll management.

Dutching is a useful tool — but only when applied to genuinely identified probability edges. If your selection skill in the underlying market is no better than random, no clever dutching mechanic produces profit. Build the underlying skill first; layer dutching on later.
