Spread Betting Explained

Doc's Sports offers spread betting explained in a way that is easy for even novice bettors to understand. The definition of point spread is the predicted scoring differential between two opponents as quoted by a sports book. The point spread is also called the line. If you have have bet a sporting event in the past, but have never bet on the point spread this will ease the process and explain how it works.

How the point spread works - When two teams meet on the playing field or on the basketball court, one team is typically better than the other or in a more favorable position because of factors like playing at home. If all you had to do were pick the winning team in a game, everybody would simply wager on the best team or the home team in a even matchup and bypass all the lines and collect their winnings at a high rate.

Jul 15, 2020 Because favorites are expected to win, you assume more risk when betting on them. Underdogs are given a “plus” designation, such as +150, +200 or +500. If an underdog is +200, that means if you bet $100 on them and they win the game, you get $200. If they lose the game, you lose only the $100 that you risked. Rotation numbers – also referred to as bet numbers – are numerical IDs assigned to every possible bet you can make at a sportsbook. It is a way to identify a wager and submit your bets without.

A point spread - Lets take, for a hypothetical situation on one of the types of football bets (using the point spread), that the Kansas City Chiefs were visiting the Detroit Lions and Detroit was established as a six-point favorite at game time, which is commonly written as Detroit -6. Kansas City would be the underdog and displayed as Kansas City +6. If you bet the favorite, Detroit has to win by more than six points to win your bet. Remember, the Lions are favored by six points, so we subtract six points from their final score on a spread bet. If Detroit were to win 27-20, Lions bettors would win their wager. If the Chiefs were to win the game by any score and you picked the Chiefs you would win not including the extra six points. If the Lions were to win, 20-14, it would be exactly six and a push, so you would get your money back.

Betting against the spread - In the sports betting industry the acronym ATS is used to label a team's record when betting against the spread. ATS records are a valuable tool in sports handicapping. A team may be playing great straight-up, winning a lot of games but at the same time they could have a dreadful ATS record because they are overvalued by the general public and the oddsmakers. And, conversely, a team could be losing a lot of games but playing in a lot of close games as underdogs and have a good ATS record going.

Bookmaker's interest - In order to guarantee a profit for the house, a bookie needs to create even action on both sides of a particular game. In a perfect world the bookie would have 50 percent of the handle come in on the underdog and 50 percent on the favorite. This ensures that the sports books are guaranteed a profit because of the 10 percent commission or 'vigorish' charged on most sports wagers. This is why there is 'movement' on the point spread. If one side on a game is being bet more heavily, the bookie must move the number in order to attract interest on the other side in order to balance action.

Spread betting is not convoluted - Many people decide that it's too arduous without ever giving it a try. In fact, once the simple concept has been grasped it becomes exceedingly painless to comprehend. Settle on if you think the oddsmakers' prediction is too low or too high. It's that straightforward. Learn the basics, so you and your wallet are not spread too thin.

While not as popular as betting against the point spread in sports gambling, betting the “over/under” isn’t that far behind. Sometimes you may see this as O/U, over-under, over under or simply referred to as “the over” or “the under.”

What does over under mean in betting?

Simply stated, it is the total of the points scored by both teams. While all sports employ an over/under betting option, by far the most money wagered on this bet is in football and basketball. Sports like baseball and hockey offer over/under options, but the vast majority of bets on those sports in based on the established “money line” to pick a winner at a set price.

Unlike a point spread bet in which you are aligning yourself with one team, you’re betting on both teams – either their offenses or the defenses – when betting the over/under. Sports books set over/under scores on games based upon numerous factors.

Understanding Sports Betting Numbers

In the NFL, most over/under scores are set in the low-to-mid 40s.In college football, over/under scores are usually in the high-40 to low 50s – in the Big 12, the land that defense forgot, it can hit the 60s.In the NBA, a typical over/under tends to hover in the 210 range. In college basketball, a standard over/under is between 140 and 155.

The hidden factors that come into play in determining a point spread vary by sport, but have common themes. Recent team history is a primary factor that sports books like to exploit. Sports by their nature are a reflective business based on developing trends from previous games (“getting on a roll”) and, if a football team has scored 40-plus points in three straight games, the over/under is going to be higher because sports bettors tend to believe that trends are going to continue. It’s human nature…until they don’t.

If a critical player – a quarterback in football or a dominant scorer in basketball – is out or playing injured, the over/under will drop.

Other factors critical in setting the over/under number include weather (where applicable), an undefinable history between teams (you know Steelers-Ravens games are going to be physical bloodbaths) and injuries that may not jump out to casual fans that mean a lot sports books are all factors that go into creating and setting an over/under line that will draw an even number of fans to both sides of the number.

The key to betting the over/under is to look at a slate of games without knowing what the over/under is and set what you believe it should be based on your knowledge of those two teams. The ones that differ the most from what you think should be are the ones to place your bets on.
