As Stephen has stated, there is no strategy with no risk and if there was whoever came up with it would keep it to themselves. Whilst I’m sure I’m not allowed to advertise a product, there is a product out there (I’m not linked to it in any way) for betting on the correct score market where you lay a 0-0 and back the 0-1 and 1-0. There is more to it than that, please don’t try this on your own, but it’s fairly low risk and I’ve had an excellent success rate with it.
Also, another benefit of that particular product/strategy is that it only uses a betting exchange so no risk of bookmaker restrictions.
note to mods – I hope I’ve not broken any rules discussing a paid for product, only outlining the strategy and benefits.
