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.
^ I think not every match has the same result and you are right, bet at your risk because these tips won't have a guarantee that has a perfect result.
Predicting what will be the result per match is very hard to know, what if you will lose in the first match and applying those strategies in the next match but it will lose again. This conclusion won't work perfectly and probably knowing the team condition is a better way to draw a conclusion on who will win in the next match.
