Last time I had a strategy. Eat ball for first half only. But the trick is you must bet a lot of matches in order to average out. I tried it a couple of times. 80 - 100 matches from as many 'plates' as possible. Each bet just bet small, e.g. $100 or $200. On average, you can make money. The first 6-7 times, I made an average of 20-30 percent returns. The logic is that first half, all the teams are fresh and strong. Plus the weaker side tends to play defensive first. But then of cos, no such thing as sure win. After I got greedy and started whacking $500 or $1K per match, bloody returns started dropping to negative, including once where damn farking sway, lost almost 80% of the matches.
So bro, no such thing as sure win one. If sure win, there won't be bookies in this world anymore.
