Anyone,

I have recently started looking at some dutch book type of betting systems where you take 2-4 horses in a race depending on size.

I am sure there are people out there who have been/are using this type of betting successfully.

Does anyone have any good suggestions regarding this form of betting ?

Essentially the way I am doing it at the moment is doing the form on a race and working out which races have only 2-4 horses with a good chance. I then stake these accordingly to win.

What percentage of the field should I dutch ? For example its no good betting on 4 horses in a 6 horse race as you can't dutch it very well. If anyone has any suggestions it would be appreciated. At the moment I am using approx 15-30% of the field. For example 1-2 horses up to 7 horse fields, 2-3 for 8-10 horse fields and 3-4 in anything greater than 10 horses.

Thanks
