I am following English premier League and Australia A league. 80-85% matches 1st half Happen corner over 3.5 that's odds 1.32-1.40 . So anyone wants to safe betting then you can bet there. Not all matches. Select for a team like Manchester United. If Manchester United and it's partner fail to cover 3.5 corner in 1st half in a match then the next match stake high between Manchester United Vs opponent team. That's the simple tricks. This tips dose not work for 100%, so bet your own risk.
Your post is contradictory, because firstly you mentioned the strategy as a safe betting method, but on your last phrase you say this tip doesn't work 100%. It means the strategy may work or not, like any other we can make use of.
Anyway, it's an interesting concept that can be useful for some gamblers as a start point to develop their own betting patterns, by improving the one shared by you.
This is why people should really be keen on believing on things specially on dealing with gambling predictions on where someone do really make out some predictions and telling it that it is on the safe side
which same as you said that nothing is assured and this one is really contradicting thats why people reading up specially noobs should really be careful on believing on things.
Nothing beats out when you do play and make bets according into your own knowledge and specifically on a certain sport.
