While we aren't exactly sure at which dollar amounts or what formulas sportsbooks use to determine when they shift the lines, we do know why they do it. It is their attempt to minimize their risk as much as possible and guarantees sportsbook profit. Lines will also move if something major happens (like Lebron breaking his leg or something) so keep an eye out for this. Ultimately, the shift in the line is done for the exact same reason to keep the same amount of money on both sides of the game. As you'll see in the strategy and tips section, shifting lines do present some interesting opportunities for sports bettors.
These are the point spread bets available for three preseason NFL football games. Let's start by identifying all of the elements of these bets so that you know what you're looking at. The first column is the two teams that are competing. This should be pretty straightforward. The next thing you will see is a plus or minus sign on each team's line. Teams with a minus sign in front of the number are the favorites and teams with the plus signs are the underdogs. In the above examples, the Chiefs, Seahawks, and Chargers are all the favorites. The Bengals, Broncos, and Cowboys are all underdogs.
Since betting on point spreads in the NFL is the most popular bet that people make, it is probably pretty important that you know what you are doing. The point spreads in the NFL are always alot closer then college football because you are dealing with the best of the best. You will almost never see a team favored by more then two touchdowns in the NFL, and most of the NFL point spreads are less then one touchdown. So, here is are best try at helping you understand how to read point spreads in NFL games.
When betting on American sports such as NBA or NFL, there are usually two main categories that appeal to punters. These are the point-spread or the moneyline. With spread betting there is a 50% chance to win on either side since the spread is actually a handicap that is given to the underdog to even out the chances for both teams on a game or a match. The majority of the time, punters will win just about the amount they bet on a point spread. Moneyline bets can be a bit more complicated and there is no point spread involved. In fact, it is a simple bet to place as one will simply be choosing who will win the game.
Futures betting also is offered on the major events in horse racing, such as the Kentucky Derby and Breeders' Cup. In horse racing futures, if your horse does not start the race due to injury or any other reason, you lose the bet -- there are no refunds. On the other hand, the odds on your horse racing futures bet also are "locked in," regardless of the horse's odds on race day.
We already know that the only thing that causes the moneyline to shift are the bets that are coming in. However, we should talk about what factors will cause the betting patterns of the public to change, and in turn, cause the moneylines to move. This will go hand in hand with the following betting strategy section. If you can master predicting when and how lines are going to move, you will crush sports betting and moneyline betting.
If you wager $100 cash on odds of +100, you are staking $100 cash to win $100 cash. Your total potential return is $200, which is your initial stake plus your winnings. If you wager $100 free play on +100, however, your total potential return is just the $100 winnings. Whether you win or lose, your free play is used up. Obviously, free play bonuses aren't worth as much as cash bonuses, so that means it's up to you to squeeze as much value out of them as possible.
Let's say you think Liverpool is going to win the game, but you think they are only going to win by three goals. If the first bet were the only bet available, you wouldn't be able to bet on this game unless you were a maniac. This handicap bet gives you more options, though! The next rectangle down is a similar bet except for this time it is Liverpool at -2, getting paid 13 to 5. If you take this wager, you need Liverpool to only win by three or more goals now, instead of four. If this happens, you will get paid at 13 to 5 or $260 for every $100 you wager. As you can see, this is more likely to happen, so you are going to be paid less for the bet. However, it does give you an option to bet what you want.
You may have heard the term “covering the spread” or the phrase “betting against the spread.” This means that if the favorite team wins an event with the point spread taken into account or that the underdog team wins with additional points, they have covered the spread. If the Packers win that game by more than 7 points, they have covered the spread.
