So ops I suggest you try as much as possible to share clear evidence to support your claims since many here won't believe that you can use that strategy to win.
This isn't some new strategy or something. Op just tweaked the underdog betting strategy basically which is quite risky for obvious reasons. I don't think he will provide more proof to support his strategy.
So for the bookies to identify the favorite, will be considering a lot of factors as well. But most bookies have the same favorite as they will have offering of similar odds.
True. They have teams working for them which is why beating them at their own game is tough as hell.
There's nothing much to worry on this because if OP think it's the best for him then he can go ahead but if he thinks that isn't going to be profitable for him then why sharing to the public, everyone of us have developed one or two mea s whereby we gamble using a particular strategy to make our chances of winning increases, everyone is just working on their own end to see what works to their own favour while gambling.
