Sport betting is strange when it wants to be, it never a sure fact the impossibility can turn possible.
When booking a bet many bets on what the majority had placed before hand.
What am I saying betting site releases games for betting and gives an option where you see what others has selected and very often it's the one with the lower odd that  people place bet on.

Last week Saturday was a Turing point for me as I refused to bet with majority(31-8-2019) and placed a draw on the match between osasuna and FC Barcelona. Most people would see it as an unwise decision but that's soccer the foolish thing can turn out to be wise.

How many times have you gone against the crowd and smiled to the bank
