What is the greatest way to decide if a horse is going to win a race?

Question by The Ollster: What is the best way to judge if a horse is going to win a race? I not too long ago went to the races in Hong Kong and bet on 3 horses to win every time and lost all my funds. I usually backed the favourite and the up coming two liked horse from the HKJC guide. Aslo I saw that the top rated jockey won more than other individuals and also some trainers were greater than other folks. What is the very best way in your viewpoint to choose horses?
