I don\'t know if this really qualifies as a system but I have enjoyed considerable success at my local greyhound track in Nottingham in recent times by sticking to trap 3 all evening. I know this may seem moronic and completely illogical but if you can do a bit of maths and can be bothered to work out your stakes correctly then it seems to pay off. Is there such a thing as a trap bias at certain dog tracks? By sticking with trap 3 at Nottingham I have had many, many winners at prices ranging from odds-on right up to 12/1 and beyond. Please bear in mind that it is absolutely crucial to start with an adequate betting bank and to acquaint yourself with the odds represented as true percentages as this will enable you to work out your correct stakes.
