Sports betting is a game of skill. The challenge is to gather and analyze as much information as you can about a game, weigh the probabilities of each team winning, and subsequently compare your opinion to the odds maker's. Make the right judgment and you win. It's as simple as that.
While luck may be a deciding factor in the outcome of any single game, and will inevitably go against you on occasion, it will balance out in the long run. Being a consistent winner in sports betting is not about luck but whether you are prepared to invest the time and effort to become knowledgeable about the sports you bet on, whether you can weigh all the factors in a cool, objective fashion, and whether you adopt a consistent, disciplined, long-term approach to your betting. Do all these and you will come out a winner. Remember, it's you against the odds maker, not the bookmaker.
The bookmaker is simply a middle-man who operates on a small profit margin and, ideally, likes to see half the money wagered on one team and half on the other, assuring him of a profit. If too much of the money goes on one team, the bookmaker will move the line or point spread to encourage bets on the other team in an effort to balance his book. The person you are attempting to beat is the odds maker and his views on each team's chances. Just by flipping a coin you will be right 50 percent of the time. At odds of 10/11 only 52.4 percent of your bets have to win for you to overcome the bookmaker's profit and break even, so you only need a very small edge to become a winner. Do your homework, bet selectively and 55 percent winning bets is definitely achievable and 60-65 percent is a realistic target. At those levels you will have an extremely profitable, as well as enjoyable, hobby.
