Look for horses who win first time out and back them until they retire.

Reason:
Horses who do not win first time out are animals that are less straight forward and in general have an inferior win rate to horses who do win first time out. Now there are strict rules to this system. Obviously if we back these horses blind every race we will be pennyless come what july. So therefore we must check the horses current well being and its trainer's form etc to make a case for a good bet. There is absolutely no point in betting on the animal if it is out of form or badly drawn. It is your choice to observe the horses current condition i.e. does it have ground conditions to suit, form on the distance etc. If you check the racing record of all the great horses, you will notice that the majority of them won first time out. Poorer animals take longer to break their maiden tag. that is why you fair greater with animals who win first time out. Try this for a short period of time, see how the results pan out.
