よくある質問
What is dutching in betting?
Dutching is a betting strategy where you back multiple selections in the same event with different stakes, calculated so that you receive the same return regardless of which selection wins. It’s named after Dutch Schultz who popularized the technique.
How is dutching different from arbitrage?
Dutching involves backing multiple selections at the same bookmaker in the same market (e.g., two horses in a race). Arbitrage involves backing all outcomes across different bookmakers. Dutching doesn’t guarantee profit — it depends on the odds being favorable.
When should I use dutching?
Dutching is useful when you think multiple selections have a chance of winning but you’re not sure which one. Instead of picking one, you can back several and get a return if any of them wins.
Can dutching be profitable?
Yes, if the combined implied probability of your selections is less than 100% (i.e., the dutching book is under 100%), you will make a profit regardless of which selection wins. The lower the combined percentage, the higher the profit.
