Several years of experience in betting on horses has been used in this book to formulate novel methods . Although this book is particularly useful when one is using the betting exchanges it is also useful for betting with the bookmakers. As one gains experience with the methods one gains the know-how to make the right choices . Although they are entirely based on United Kingdom horse racing, because of the international nature of the betting industry, they are also useful in other countries such as North America and Australia.Price movements during the overnight stage of racing and during the short period prior to commencement of racing often give rise to patterns that can be used to decide when to lay ’ or ’ back ’ horses. Several examples of races where these patterns are seen during the past 12 months of racing are selected and presented for the benefit of the reader. Stategies are also developed to exploit the betting in running opportunity.
