How many times must the serve be broken to win a set ?
In horse racing in the United Kingdom , the " place " is set strictly by the Jockey Club and will depend on the size of the field ( that is , how many horses are running ) so that the " place " may be just 1 st and 2nd , 1 st 2nd and 3rd , or even 1 st 2nd 3rd or 4th on a big race like the Grand National , and may pay or the odds .
