When betting on the underdog, the first step is the same. Divide the positive moneyline by 100, which in the case of the Grizzlies in the above example would give you 2.10. Then, multiply your stake by that number to get your potential winnings. $450 multiplied by 2.10 is $945. Essentially, this means if you risked $450 on the Grizzlies, you would stand to win $945.
Above, you can see several numbers to the right of both teams. These all represent the different lines that are available on the San Francisco vs. Los Angeles game. The first set of numbers for both teams is the point spread, the second set is the moneyline, and the third set is the over/under (a.k.a. totals). We'll explain each of these lines more in-depth below.
Apply the money line. It's easiest to think of money lines in relation to $100. A minus sign means you have to bet that much money in order to win $100; a plus sign means that a $100 bet will return that much money. If you bet on Chicago at -110, you'll have to wager $110 in order to get back $100 (plus your original $110). If you bet on Detroit at +145, then a $100 bet will give you $145 (plus your original $100).
The second way is “eyeballing it.” If two teams play 10 times, how many times do you think a certain team is going to win? If you say they are going to win 6 times, then you think they are going to win 60% (6/10) times. Looking at it as a series of multiple games makes it a lot simpler for you to grasp and predict. Then, you just convert that number to a percentage and compare it with the implied probabilities offered at the sportsbooks. If there is value, go for it.
If the bookmaker was only confident enough to give Seattle a field goal’s lead on the Patriots, it was clearly going to be a tight game. Oddsmakers aren’t often that wrong about flagship games like the Super Bowl. All things being equal, it’s likely the betting public would have taken the Seahawks to win the game and have been done with it. But throw in the point spread that gave the Patriots 2.5 points, and the proposition seems more equal.
The way the sportsbook does this is by putting out a betting line that is based on how many points they think the better team is going to win by. This is a lot like how our older siblings would "spot us" a few points when we played each other in basketball as kids. For example, let's say that Florida Gators are playing the Arkansas Razorbacks. Let's also say that Florida is the better team and the sportsbook thinks they are going to win the game by seven points. They can't just let everyone bet evenly, or everyone would bet Florida and clean them out. Enter the point spread. The sportsbook would set the point spread on this game at -7 for Florida to win. The negative sign before the number signifies that this team is the favorite to win. This means that if you want to bet on Florida, they have to win by more than 7 points for you to win your bet.
If the public comes out and bets really hard on one side, the line is going to move a lot making the odds worse on that side and a lot better on the other side. If you’re planning to bet against the public, you should wait to bet until the line moves as far as you think it is going to. Be careful, though, if you wait too long and some big money bettors bet, they can move the line back.
These are the handicap bets that we have already talked about. These are your straightforward bets that pay out according to the spread and odds posted. Draws are treated as a loss with this format. If you just scrolled to this section first, scroll up and read the general section about handicap bets because this type is addressed extensively with some great examples there.
You have three choices for the three betting options: Home, Away, or Draw (tie). The result of the game is decided after regulation play (90 minutes plus injury time). Overtime, the Golden Goal rule, and penalty kicks are not taken into consideration for soccer bets unless otherwise stipulated. You can usually bet on a winner or advancement (including OT & shootouts) but with different odds would be given.
One of the main reasons that sports bettors like to bet is the action and excitement of winning and losing. Many sports bettors would rather take the risk of winning or losing than having the option of pushing (a tie) on their bets. For this reason, many sportsbooks offer what are called no draw handicap match bets. These are bets on an individual match that are designed so that there is never going to be a tie. In the standard handicap bet examples we used above, you saw that all of the bet options were in whole numbers. This allows for there to be draws.
On a moneyline bet of -300, you’ll need to win your bet 75% of the time just to break even. When your odds jump even higher to -400, you’ll need to win your bet 80% of the time to show a profit. You are risking a lot to win very little and even though a large favorite will win most of the time, when they do lose, you will find yourself out a lot of money. I try to stay away from large favorite moneylines, because the amount risked is very high and the payoff is low.
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value. The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
