The overall purpose of spread betting is to create an active market for both sides of a binary wager, even if the outcome of an event may appear prima facie to be biased towards one side or another. Against a team that was weaker a powerful team could possibly be matched in a sporting event . If the wager is only»Will the favorite win?» , more stakes are very likely to be made for the preferred, possibly to this extent that there will be very few betters willing to take the underdog.
The point spread is fundamentally a handicap to the underdog. The bet becomes»Will the preferred win by more than the point spread?» The point spread could be moved to any amount to create an equivalent number of participants. This permits a bookmaker by accepting wagers to act as a market maker. The bookmaker acts as the counterparty for each player, and charges a commission, or vigorish. Provided that the entire amount wagered on every side is roughly equivalent, the bookmaker is unconcerned with the real outcome; profits instead come in the commissions.
Since the spread is intended to make an equal quantity of wagers on either side, the implied probability is 50% for both sides of the bet. To gain, the bookmaker must pay one side (or both sides) less than this notional quantity. In practice, spreads may be perceived as slightly favoring one side, and bookmakers often reevaluate their odds to handle their event threat.
One important assumption is that to be credited with a win, either team only needs to win from the minimum of the principles of this game, without respect to the margin of victory. This suggests that teams at a winning position will not necessarily try to extend their perimeter –and more to the point, each group is only playing to win instead of to beat the point spread. This assumption does not necessarily hold in most situations. By way of instance, at the conclusion of a season, the total points scored by a team can impact future events such as playoff seeding and placement to the amateur draft, and teams can»run up» the score in such situations. In virtually all sport players and other on-field contributors are forbidden from becoming involved in sports betting and thus don’t have any incentive to consider the point spread throughout play; any attempt to manipulate the results of a match for gambling purposes would be considered game fixing, along with the penalty is generally a lifetime banishment from the sport, such is the lack of tolerance for gaming in sport.
