Betting Spread

The general reason for the betting spread is to create an active market for each side of a wager, even if the outcome of an event may appears biased towards one side or the other. In an event that is competitive, a strong team may be matched up towards a historically weaker team maiking almost every game having a solid favorite and a good underdog. If the bet is simply “Can the favorite win? there would be many easy winners, but with the point spread the question becomes can the favorite cover, or win by the posted margin. This results in more bets that are likely to be created for the favorite, possibly in order to such an extent that there would be very few betters willing to make underdog.

The point gambling betting spread is essentially any handicap towards the underdog. The wager becomes “Will the favorite win by more than the assigned spread?” The point wagering betting spread can be moved at any time to create an equal number of participants on each side of the wager. This permits a bookmaker, to make an efficient market, by accepting wagers on both sides of the wagering betting spread. The bookmaker charges a commission, or vigorish, and acts as the counterparty for each participant. Provided that the total amount gambled on each side will be roughly equal, the bookmaker is unconcerned with the real outcome; profits instead come from the commissions.

Because the betting spread is intended to produce an equal number associated with wagers on either side, the actual implied probability is 50% for both sides with the wager. In order to profit, the bookmaker must pay one side (or either side) less than this wagered amount. In practice, it may look like the books are favoring one side, so bookmakers will often revise their odds in order to manage their event risk.

Betting Spread was invented by Charles K. McNeil, a arithmetic teacher from Connecticut which became a bookmaker inside Chicago in the 1940s. The idea started to be popular in the United Kingdom within the 1980s.

Betting Spreads are frequently, though not always, specified in half-point fractions to eliminate the possibility of a tie, known as a push. In the event of a push, the game is considered no action, and no money is won or lost. However, this is not a desirable outcome for the sports book, as they are forced to refund every bet, and although both the book and its bettors will be even, if the cost of overhead is taken into account, the book has actually lost money by taking bets on the event. Sports books are generally permitted to state “ties win” or “ties lose” to avoid the necessity of refunding every bet.

A teaser is a bet that alters the betting spread in the gambler’s favor by a predetermined margin – in American football the teaser margin is often six points. For example, if the line is 3.5 points and the bettor wants to place a teaser bet on the underdog, he takes 9.5 points instead; a teaser bet on the favorite would mean that the gambler takes 2.5 points instead of having to give the 3.5. In return for the additional points, the payout if the gambler wins is less than even money. At some establishments, the “reverse teaser” also exists, which alters the betting spread against the gambler, who gets paid at more than evens if the bet wins.
