Anyway the best way to win is not to bet at all, you will never beat the 10%-20% profit margin the bookmaker makes at least not unless you are involved in some sort of cheating, and apparently plenty of that goes on in horse racing and maybe football too. So you have to beat the bookmakers margin and the money the cheats take out of the game too!!
With the ability to lay horses now there is too much oppertunity for cheating
but I have yet to see the race where *all* the jockeys in a race jump off their horses before the finishing line :D
