If you are searching for a guaranteed way to make cash from horse racing then this book is definitely not for you. The author, David Duncan plainly states that there is no such thing as a racing 'certainty', and rightly so. His 12 golden rules of gambling are precisely what they say; Golden.
Whether you are an absolute beginner or an veteran person in the world of betting, there is something you can take and gain knowledge of from in this book. David talks about horse selection, racing systems and staking plans together with many other things. He backs up his judgment and thoughts with good reasonsing and evidence which a lot of other writers neglect to do.
By using previous experiences, statistics and math, David Duncan has written a concise book which is effortless and simple to absorb. I believe that the hidden meaning in the book is that horse racing is all about opinions, and Mr. Duncan's is well worth listening to.
