I want to tell you about a betting strategy I use:

I use this system ONLY for CUP matches.

So here it goes: I choose a particluar Cup on which I focus all my attention.
Last week I decided to choose the French Cup.
I take 5 matches in which teams from the first league that don't have
any interest in winning the cup really (and so will field their younger players)
play against a lower team from the second or third division.

I pick out the best 5 games and then place my bet on the underdogs that
probably have odds around 7.0 or even higher.

I bet £10 on each game and almost every time I get at least one winner
if not more from those 5 games and so I get a profit of at least over £20
every cup leg.

This system is great, I hope you'll like it.
