There are two ways to bet on horse racing. One involves lucky numbers, favourite colours in the silks, or whimsical associations with horse names. In other words, it relies on blind luck. Serious punters, on the other hand, study the comprehensive form before placing a bet on a race.
This is not to be confused with a racing form, although the two terms are intricately linked. A racing form or race card gives recent details about a horse’s career history, while comprehensive form brings in more context.
