First of all, football is a sport. let's be clear about that. Professional players play the game to win, punters bet on them to win, lose or whatever... SGPools offer bets relying on odds on the outcome of a game. No one can help you if you are "naïve" to think that you can predict the result of any game and put money down to think you are right. If the result doesn't work out as what you expect, you shout "kelong!" like the uneducated uncles do every night at the coffeshop near my place.
I hear some of the logic such as, "Brazil only need a draw to be in the next stage so a draw is likely..." or "Costa Rica already thru, so they no need to play so hard to win and keep their players for the second round..." and I have to laugh. They think Brazil want a draw, they will get a draw? If sports is like that where everyone can determine the results, then no need to play sports already. 90 minutes is a long time to manipulate a fixed game without people noticing something amiss.
Your views on SGPools is how you look at it, not a reflection of what is true. It is a bet on odds, nothing more. Sometimes you win, sometimes you lose - odds are that in the long run, you lose because of "gambler's ruin" setting in. And in football, the result is notoriously difficult to predict.
