The last types of bets that you should be aware of when betting on the NBA are proposition bets. A prop bet is a wager in which you bet on whether or not something is going to happen in a particular game. For example, will a certain player make more than four 3-pointers in a game? Which team will score first? Which team will win the opening tip-off? Will a certain team shoot over X % from the field? All of these are examples of prop bets that you can make on a particular NBA game.
The number that comes after the plus or minus sign is how significant of a favorite or underdog the teams are, regarding points. In the first game, the Bengals are a 1.5 point underdog. This means that the sportsbook thinks the Bengals are going to lose the game by 1.5 points. This means, by default, that the Chiefs are a 1.5 point favorite. This means the sportsbook thinks the Chiefs are going to win the game by 1.5 points.
Let's say you decide to bet $100 on Liverpool, and they lose the game by two goals. You would push on the first half of your bet and win the second half of your bet. You would receive your $50 back for the push and $43.48 in profit on your second bet. Basically, the sportsbook would hand you back $143.48 total, which would include $50 for the push, $50 for your original bet, and $43.48 for the push.
This is four different games you can bet on, right? Wrong. These are several different handicap bets that you can make on a single game of soccer. Each of the individual rectangles is the same as the point spread bets we talked about earlier. For example, the first rectangle is betting on Liverpool at -3, getting paid 6 to 1. This means that if you take this bet you need Liverpool to win by four or more goals and you will get paid 6 to 1, or $600 for every $100 you wager.
Where people seem to get confused with moneyline bets is with how they are presented and how they pay out. While the criteria to win a moneyline bet will never change, the amount you win and how the bet is presented will change. Don’t worry, though. It’s easy to understand if it’s presented to you properly. We are going to cover this thoroughly in the coming sections. You’ll be a moneyline expert ready to crush the books when you get done with this guide.
What the sportsbook does to fix this is they "spot" the underdog team some points to make it fair. Obviously, these points aren't included in the actual score to determine who wins or loses the game, but they are calculated in to determine who "wins" the game in the sportsbook's eyes. If you ever played basketball as a kid against an older sibling or your dad, they would sometimes "spot" you some points to make it fairer. Let's say you were playing to 20 points, they might "spot" you 10 points to make it fairer. They would then have to score 20 points to win, but you would only have to score 10. This gives you a chance actually to win the game.
One of the biggest mistakes that bettors make is trying to make a judgement on every single game that's taking place. This is especially true of those who only focus on the NFL. There aren't that many games each week, and bettors think they stand the best chance of making money if they can predict the outcomes in all of them. This is not an approach we recommend.
If you are betting on a sport where there are multiple entrants, like in a race or tournament, you may find that every entrant is paying out at favorite odds. This is because it’s much more challenging to pick a winner from a large field, and the sportsbook will be rewarding you for that. Just know that when you see the plus sign, you will be getting paid better than even money for a correct pick.
Without losing you with the math, the implied probability (or how often you should win) of a +250 bet is 28.6%. This means that you should win this bet 28.6 out of 100 times. This is what the sportsbook thinks will happen. You, however, think it should be +125. The implied probability of that is 44.4% meaning that you think you should win the bet about 44.4 out of 100 times.
Ideally, the lines I release will balance the action equally, so that the winners get paid out from the pockets of the losers and we take the vigorish. That’s an ideal that rarely happens – especially in sports without a pointspread, like NASCAR and golf. If Team A is getting too much action, I’ll move the line toward Team B to try to achieve that balance. My personal preference is to tweak the vig from –110 to –105 or +100 before taking the bigger step of moving the spread a half-point or more.
In this instance, the Dodgers are the favored team, as signified by the negative numeral. It would cost you $130 in order to collect a $100 payout on a Dodgers victory (plus the original wager of $130). But if you bet $100 on the Cubs, you'd collect $120 if they win (plus the original wager). In other words, you'll have to wager more money on Los Angeles than you would Chicago in order collect $100 on a bet.
That was all before Charles McNeil, a math teacher from Chicago, invented the concept of the point spread. An avid gambler, McNeil created what he called “wholesaling odds” and started his own bookmaking operation in the 1940s. He started out offering this new style of betting on football, but his business model grew to include basketball. McNeil changed the way sports betting was done, and his legacy lives on today in what we now call the point spread.
