Successful betting is not just about picking winners: it's also about whether it's worth backing them at the odds you are offered. The question to ask yourself every time is am I getting good enough odds to justify plonking down my money?

To find out, you have to use the same tools as we do - and you have to use your special advantage. That is that you are concentrating on just one race at one meeting on one day or on whatever single event you have picked on. We, on the other hand, have to cover hundreds of races and matches and events every day, and we can't get them all right.
