**Dutch Betting Explained**

A betting term punters will at times encounter is “Dutch,” as in, “I was uncertain about the fourth race, so I did a little Dutch betting.”

Racing wagering is full of colourful terms.

It is called Dutch betting after a famous American punter/slash mobster named Arthur Simon Flegenheimer. Dutch was his nickname, although he was of German and Jewish lineage.

The definition of a Dutch or an Arb bet is a series of punts that returns a profit if the sum of the reciprocals of the decimal odds of each selection is less than one and each selection is less than one and each bet is sized such that the payout in each outcome is the same.

If that last bit confused you, do not feel alone.

We wrote it and we do not know what it means.

If we were to boil it down to one simple sentence, it would be, “Dutching is a way to back more than one runner for different odds in the hopes that the profits will exceed the losses.”

In its simplest form, a Dutch bet involves two legs and could be used for sports betting, such as tennis matches or footy games.

The mathematical formulas are not complex, but as simple punters, we require zero formulas.

**Pro Group Racing Dutch Betting Calculator**

We have a calculator that will run all the formulas for you. You do have to enter the odds in decimal format, something the Australian bookmakers use universally, plus the amount you would like to stake.

Our Dutch Betting Calculator will do the maths for you, up to 10 runners.

Yes, important races often have more than 10 horses, but as you probably know, it is often the case that in a 12-horse race, there could be several you would not look at for any price.

Dutch betting is not a substitute for studying form when making racing selections. Eliminating the stone motherless before filling out a bet slip, and then combining the homework with Dutch betting, is a good path.

True, there are the occasional boilovers, such as when Prince of Penzance won the 2015 Melbourne Cup from $101, but those are rare and the technique of dutching bets is based on percentages over a long term.

**Dutch Betting Examples**

The following examples are based on the assumption of someone wanting to bet a total of $100 on a race. Easy maths, remember?

In this example, we will use the Dutch Betting Calculator to determine what size bet should be placed on each runner.

We arbitrarily picked runners with the following quotes: $3.50, $6.50, $9, $13 and $21.

We filled in the odds for each horse (remember to use decimal format), filled in the box at the bottom left of the table, selected Total Bet from the three radio button options, and then clicked Calculate.

The Dutch Betting Calculator gives the result that the $3.50 chance would need a bet of $42. A win would return $147 and the profit would be $48. If all the other bets were win bets, the remainder of the bets would be lost, in this case $58.

The next three selections would require wagers of, in descending order, $23, $16 and $11. The $21 chance would require only a $7 wager to return the same profit as the $3.50 chance.

The Dutch Betting Calculator can also determine how much of a wager is required for a punter to collect $100 profit. Simply click the Total Collect radio button to learn that the total of all five wagers would be $68.

Switching to the final radio button, labelled Clear Profit, supplies the information that for a profit of $100 for the race, with the odds given, would require a total bet of $208.

It is a good wagering practice to approach a race with a pre-determined risk amount and in most instances, we would lean in the direction of using the Total Bet button.

Still, it is quite interesting to explore the other values and how those values shift with different odds or a different number of selections.

Of course, most punters would never back five horses to win a race, but Dutch betting and the Dutch Betting Calculator is excellent for those races where there is a short favourite and another strong chance a bit longer.

If the above example were to be limited to the top two horses, the Total Bet for the $3.50 chance would be $65, while the second line at $6.50 would bet for $35.

Total Collect calculates to a bet requirement of $44, with $29 on the $3.50 chance and $15 of the $6.50 chance.

The Clear Profit calculation (trying for $100 worth of dividends) shows that the $3.50 chance should be wagered for $51, while the $6.50 chance would need a wager of $27.

**Conclusion**

Dutch betting is a tactic that takes some of the uncertainty out of making racing selections. Try plugging some figures into our Dutch Betting Calculator and explore various scenarios to take your race punting up several notches.

Remember to allow some room to account for bookie margin.
