What is dutching and should i be doing it ?
Simple really. Dutching is betting on all the outcomes with different bookies. In dutching you don't lay anything, but cover all the outcomes with back bets.
Tennis and Football can work well with Dutching. You can't really do it with horses unless there's very few runners.
Its most useful when combined with Football offers. For example:
Back Liverpool with Bet365 (for 2 up offer) at odds of 2.8 for £20
Back Man U with Paddy (for 2 up offer) also at odds of 2.8 for £20
Back Draw with Boylesport (for crossbar offer) at odds of 3.3 for £17
In this example, whatever the outcome you will make a £1 loss but will have qualified for all three offers. If lucky you can find odds that guarantee a small profit.
Its also good for placing mug bets with several bookies at once.
Some dutching calculators will give you exact amounts to bet like £16.53 This is the most effective but it kind of makes it look to the bookies that you are up to something. I usually try to round up or down to whole pound amounts or sensible looking figures like £12.50
