There's not really a simple answer, but just keep in mind that a sports books want to maximize profit and b there are smart people out there who bet more when the line is worse. As for how they might determine the lines aside from actual betting which might be important for instance in setting opening lines , there are numerous things they can do.

Under what circumstances would you lose money? Suppose, e. If I give them better than odds, I could lose money. So I only offer lower odds that I can afford.
If they don't bet with me, I lose some business--but no money; if they do bet with me and win, then I'm guaranteed to make money. If there's a competitive market, the odds I offer will be close to This is how a market prices in probabilities. They said they were hedging risk the no-lose strategy I described but they were secretly estimating probabilities--and eventually, inevitably getting them wrong or just getting unlucky.

The most important thing when it comes to betting successfully and effectively is information. You can never have too much of it, so the best horse bet calculator for example is the one that allows you to enter — and receive — the most information about the possible horse racing bet you want to make.
There are many different types of bet, and each is suited to different situations. A good betting calculator will give you the option to calculate the simplest of bets, if you need to, but also to see how you could profit from doubles, triples, Trixie bets and Yankees among many others.
The following are some of the best bet calculators available online at the moment, and a wise place to start looking. OddsMonkey is a site devoted to showing novice bettors how to really get inside the betting game and turn it to their advantage using the accumulated knowledge of experts. Of perhaps most interest is their matched betting calculator, which will show you how to make the best out of every free bet you get on signing up for the various online bookmakers.
This is in addition to the range of tutorials which show you how you can make the most of the information that the bet calculator provides. The beauty of Freebets is the way everything is set out on the site. With many other betting calculators, the information is muddled together and it can be hard to tell what information goes where.
With Freebets. At the end, it will then display your results in a way that explains everything clearly. Some other calculators can make it difficult to tell whether the results are your gross winnings or just the profit, but there is no risk of that here. As a side benefit, as the name suggests, the site is a handy reference for which bookmakers are offering the best free bet at any time.
It lets you choose whether you want to make an each-way bet and calculates your potential returns, and the way in which it displays the results makes it easy to see exactly how they have been calculated. The site is also highly useful as it offers information on the ways to get one-off special offers, such as exaggerated long odds on Manchester United to win at home against a team in the bottom half of the Premier League.
In short, you can come for the football odds but stay for the start-to-finish gathering of information. If you know all about sports but not much about betting, then it can be really tough to find the best bets and the best bookmakers with whom to place them. Taking the chance to inform yourself before hitting up the betting sites is essential, and can make the difference between a once-bitten, twice-shy bettor and someone who beats the bookies on a regular basis.
