Hi , I like to bet like this, its not bad and if you perservere it generally pays off. Check it out see what you reckon.
On a race I take an exacta with all odd Nos to win and even Nos to run second. On the same race I take another exacta, Evens to win odds to run second. When you get your nose infront on the day ,stop. Go again tomorrow. I usually bet in half units.
