There are innumerable so-called gambling experts who will dish out information of their systems to 'beat the bookie' or generate an additional revenue from gambling, at a price of course. I will not do this. I'll only provide information on gambling, bookmakers and odds that you can either use or ignore however you like.
One thing to remember is that the vast majority of those who participate in gambling will be net losers in the end. good games to play is the very reason that bookmakers are earning huge profits across the globe.
Bookmakers can take huge losses occasionally, like when an unpopular horse takes home the Grand National. However, they take their risks and set up markets with an amount of margin to always profit in both the long and medium term. This is so long as they have their numbers right.
Bookmakers need to first determine the probability of an event occurring before they set their odds. They use statistical models that are based on data from many years often for decades about the event or the team/competitor. It is not possible for sports to be 100% predictably. However, bookies can sometimes be inaccurate in their predictions about the likelihood of an event. This is due to the nature of a match or contest that is in opposition to statistical probability and common sense.
Just look at any game and you will find an occasion when the underdog wins against all the odds in the literal sense. Wimbledon beating then-mighty Liverpool in the FA Cup Final of 1988 for instance as well as the USA beating the powerful USSR in ice hockey during the 1980 Olympics are two examples of where you could have gotten handsome odds on the underdog. You could also have walked away with a substantial wedge.
The big bookmakers spend a lot of time and money to ensure they are offering the best odds. They take into consideration the likelihood of an event and add the extra that allows them to make profits. If an event has an probability of 1/3, the probability of it happening would be 2/1. That means there's a two-to-one probability of the event happening.
If their figures are correct, however, they would lose money if they established these odds. Instead, they might have odds set at 6/4. In this way they have constructed a margin to ensure that over time, they will make money from betting on this choice. It's the exact identical to roulette in a casino.
What can you do to spot instances of bookmakers being wrong? It's more easy said than done however it's not impossible.
One option is to become very good at mathematical modelling and then create an understanding that takes consideration as many factors that influence the outcome of an event as possible. This tactic has a problem. It is not able to account for all the variables that affect the individual's mental state, no matter how complex or thorough it might appear. When play free games can hole a major-winning five foot putt in the 18th at St Andrews it is as much down to their concentration as the weather conditions or day of the week. The math can get quite complex.
There is also a niche in the sport you enjoy. Bookmakers tend to focus their attention on the events that make the most profit, generally found to be football (soccer), American football and horse racing. It's difficult to beat the bookies when betting on Manchester United v Chelsea matches. Unless you work for any of the teams or are married to one of the players or managers the odds are very high that the bookmaker who is putting the odds has more information than you do.
However, if you are betting on non-league football or badminton or crown green bowls, it is possible, through hard work reading numerous stats and general data gathering, you can start to gain an edge over bookmakers (if they even provide odds for these events, which many do).
What do you do when you've got an an edge in information terms? You must follow the rules.
Value betting involves placing your place a bet on a particular selection at odds higher than the probability of the event happening. For example when you calculate the likelihood of a specific non-league football team (Grimsby Town, for example) having a chance to win their next football match as 33% or 1/3, and you find an online bookmaker that has set the odds at 3/1, then you've got a value wager in your pocket. The odds of 3/1 plus the margin imposed by the bookie, suggest that the odds are between 1/4 and 25 percent. The bookie, according to your opinion now is underestimating the chances of Grimsby, so you have effectively constructed an 8 percent margin for yourself.
Of course Grimsby (as is often the scenario) could blunder their lines and fail to win the match, and hence the bet could be lost. If you continue to look for and place bets on the value bets, over time you'll earn a profit. If you do not, in time, you'll lose. Simple.
The issue is: Do you have the time, or the desire to invest hours in studying and refining your sport areas, or looking for the most value-for-money bets? If yes, great for you, go for it.
