Online sports betting is expanding everyday and it’s not hard to understand why. It combines two all-time favorite past-times – sports and taking risks. We can’t all play professional sports. Most people can’t take weekly trips to Vegas. But thanks to online sports betting you can have the thrill of watching sports and winning money at the same time. All in the privacy of your own home! It doesn’t get much better than that.Before you start placing bets you need to understand a few of the basics. This article gives you an introduction to the terminology used in online betting. You don’t want to make any bets that you don’t completely understand. Here’s where I wish to emphasize another good word of advice, always search out the top spots betting advice and assimilate that advice before you place any money on the line.Straight Bets – With a straight bet you’re simply betting on a team to win. The amount of points a team wins by doesn’t matter. If the Cowboys and Jaguars are playing you simply bet on which team you think will win. This is the most basic bet.Betting a side – This is similar to the above bet. You’re choosing a “side” or a team you think will win.Point Spread Betting – A sports book will list which team is the favorite to win a particular game. They’ll also show the estimated amount of points they’re expected to win by which is called the spread. So they don’t just say the odds are on the Cowboys to win. They’ll say the Cowboys are expected to win by 7 points or 11 points, etc. If you bet on the Cowboys to win but they only win by 5 then you haven’t won your bet. They didn’t win by enough to cover the spread.Against the Spread or ATS – This is similar to the above bet. Instead of betting just on who will win, you’re betting they’ll win by more or less than the amount of the expected spread. I think you are beginning to see why I insist that you find the top sports betting advice. In your research look for a system, a proven system where the promoter of the system has a dedicated following of winners. At the end of this article I will point you to one, but there are dozens more. Find the one right for you.Over/Under bets – As well as listing a favorite team and the point spread they’re expected to win by, the oddsmakers will also list a total over/under score. This is the total amount of points the teams will score during the game. If the number is 47 then they’re anticipating both teams to score a combined total of 47. If you bet “over” then you’re betting the total score will be over what’s expected. If you bet “under” then you’re anticipating the total score to be less.Parlays – Parlay betting is when you group several bets on one ticket. Let’s say you make three bets, but instead of placing them separately you place them all on one ticket. If you win all three the payout is greater than if you’d played each bet separately. However, if you lose even one bet the parlay is a loser. You must win every bet on the card.Future Bets or betting “Futures” – A future bet can be a profitable bet for small bettors but the odds are high. It involves betting on a game such as the Super Bowl while the season is just beginning, etc. You’re betting on which team will win a future event before it’s even been decided who will play in the game.There are many other variations of bets but this gives you the basic online sports betting terminology to understand the most popular bets.
