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.
Not going to happen.
Sportsbetting markets are efficient so there is virtually no long term exploitable pattern for sportsbettors to be able to take advantage of. Unless you have extensive backtesting/insider info/arbitrage opportunities.
Your EV, at the end of the day, is likely still going to be negative regardless of how many times you do this - or how many times you have won in the past.
