Advanced Dutching
📖 What is Advanced Dutching?
Advanced Dutching is the version of the strategy for 3 or more selections in the same event. It is ideal for horse racing, tennis tournaments, golf championships, and any event with multiple possible outcomes.
This technique allows you to cover multiple possibilities with a single bet, guaranteeing return regardless of which selection wins (as long as odds are favorable).
📐 General Dutching Formula
For N selections, the formula is:
Bet per Selection = (Total Stake / Sum of Reciprocals) × (1 / Selection Odds)
Where the Sum of Reciprocals is the sum of 1 divided by the odds of each selection.
Sum of Reciprocals = Σ (1 / Odds_i)
The guaranteed return is calculated as:
Return = Bet_i × Odds_i (constant for all selections)
📊 Example with 3 Selections
Suppose a horse race with odds 2.0, 3.0, and 5.0, betting $100:
- Sum of reciprocals = 1/2.0 + 1/3.0 + 1/5.0 = 0.5 + 0.333 + 0.2 = 1.033
- Bet Horse 1 = (100 / 1.033) × 0.5 = $48.40
- Bet Horse 2 = (100 / 1.033) × 0.333 = $32.27
- Bet Horse 3 = (100 / 1.033) × 0.2 = $19.36
- Guaranteed return = $96.80 ($3.20 loss)
📈 Example with Favorable Odds (Profit)
With odds 2.5, 3.5, and 4.5, betting $100:
- Sum of reciprocals = 1/2.5 + 1/3.5 + 1/4.5 = 0.4 + 0.286 + 0.222 = 0.908
- Bet Selection 1 = (100 / 0.908) × 0.4 = $44.05
- Bet Selection 2 = (100 / 0.908) × 0.286 = $31.50
- Bet Selection 3 = (100 / 0.908) × 0.222 = $24.45
- Guaranteed return = $110.13 ($10.13 profit)
