I think betting on the matches is a good way to earn some extra money. Many times I was able to win sizable amounts of money. So, do you bet on the sports matches? Have You ever tried it? I can say from my own experience that it is quite addictive, however if we are good at it, it will surely bring us a lot of money ^.^
Over your lifetime
Calculating your bets, if you break even you will do well
My tip for Grand national is
Butlers Cabin - Rider Tony Mcoy
Be very very careful.
A friend of mine used to be a professional jockey. He claims that by analysing the race stat sheet that he can consistantly pick the top three horses at least 60% of the time. I grilled him on how to do that, and I have no dought that he can hit over 60%. However, he refuses to gamble any more. He gets so focused on a bet and can convince himself that he is so absolutely correct that he is likely to bet the house and farm on one race and then loose everything. That's the voice of experience!
