Many large bookmakers will allow bettors to adjust point spreads on football in exchange for an increased commission on the bet. In general you should not buy points except under special circumstances.

Buy half points in football only when the unadjusted point spread is 3. The way points are awarded in football there is a 1 in 7 chance that games will be decided by 3 points. Although in football scores are by 3 and 7 points (touchdown) 3 point margins are twice as common as 7 point margins.

**6. Are there any advantages in betting far before the event occurs?**

Particularly in football where lines are set early in the week and betting takes place throughout the week, a sharp handicapper will believe a point spread will move during that week. That bettor will make his bet early in the week in order to take advantage of his gut feel on the movement on the points spread. Occasionally his instincts will prove wrong.

In the blindfold method the early line advantage is taken in terms of simple probability and value. In the case of football it states to bet on early lines on the favorite at exactly either 2.5 points or 6.5 points provided there has been no prior movement. The reasoning behind this is that if the line moves, the move from 6.5 points to 7 points (or 2.5 to 3 points) is far more significant than a move from 6.5 points to 6 points due to the nature of the game's scoring.

**7. Is it possible to take advantage of a disparity in point spreads among bookmakers?**

This is called "middling" a bet and to middle a bet you need to find 2 separate sportsbooks that are putting out different lines. Although this does not happen very often, you may find this on college games where less information is available. For example if one team is favored by 1 point with one sportsbook and 3 points with another sportsbook then you may lay 1 point with the first and take the underdog in B. If the game ends with the favorite winning by 2 points you would collect on both ends. If the favorite wins by 1 or 3, one would tie and you win the other. Middling a bet occurs through wagering at two establishments. Middling may also occur by buying back a bet at the same or different establishment.

**8. What are reverse bets, parlays "if" and round robin bets?**

Parlay are a single bet that bets on the outcome of more than one sporting event. There are two types: point spread parlays and money-spread parlays that use point spread lines or money lines to determine the payout. Bookmakers charge an increased premium for parlays compared to straight bets since the bet is made on 2 events. The logic in the increased "vig" is that by betting parlays it would decrease the number of bets made thus requiring an increased premium. The vig in parlays is not as obvious as in straight bets and is built into the odds. In the case of an event in a point spread parlay resulting in a "push", the bet is treated as if it were a straight bet on the bettor's other selection. Round robin bets are

"If" bets are similar to parlays that a wager on one team is only valid if the initial bet wins. The amount of the second bet can range from a portion of the winnings of the first bet to the full amount. If the first bet is a loser then the second bet is automatically invalidated. The biggest difference between a parlay and an "if" bet is that in the parlay the entire amount of the first event is put on the second event (in the case the first event wins), whereas in the "if" bet you may control the amount wagered on the second event. This results in more control for the bettor on the amounts wagered. In an "if" bet, game times are irrelevant. "If" bets are popular also because it allows the bettor to see that a second event will be more likely to happen when a first event occurs. "If" bets are particularly effective late in the season when many teams are competing for a few playoff spots. Since some teams rely on other teams to lose in order to qualify for the playoffs, their motivation may vary according to the result of other games. Take advantage of "if" bets in situations such as these whenever possible since they can provide an edge to the bettor.

Reverse bets are composed of two "if" bets involving the same two teams.

Round robin bets is a way of designating a series of parlays. For instance, if a player asked for a $100, three-team Round Robin with teams A, B, and C, he/she is simply requesting a two-team parlay with teams A and B, another parlay with teams A and C, and another with teams B and C, for a total of 3 individual parlays, each for $100. The total amount risked would be $300.

Round Robins get more complex as the number of teams increases. A four-team Round Robin "by twos" for $100 would mean that the bettor wants four teams to be included in a combination of two-team parlays. This would be a total of six individual two-team parlays, for a total risk of $600. If the request is for a Round Robin "by threes", it would include a total of four possible combinations, for a risk of $400. The number of possible parlays can be calculated by the formula below:

Number of possible parlays = (N*N) - N / 2 where N is the number of teams you wish to include in your round robin.

Eg. A player requests a $100 four team Round Robin "by twos", with teams A, B, C and D. The possible combinations would be as follows:

Teams AB $100 to win $260 Teams AC $100 to win $260 Teams AD $100 to win $260 Teams BC $100 to win $260 Teams BD $100 to win $260 Teams CD $100 to win $260

If all four teams win, the player wins $1240, while risking only $600! If one game loses, there is still a profit, even though three of the parlays would lose. The three winners get back $780, plus the $100 laid for each parlay, for a total of $1080. After subtracting $300 for the 3 losers, the player profits $480!
