"IF" Bets and Reverses
I mentioned last week, that if your book offers "if/reverses," you can play those instead of parlays. Some of you might not learn how to bet an "if/reverse." A complete explanation and comparison of "if" bets, "if/reverses," and parlays follows, along with the situations in which each is best..
An "if" bet is strictly what it sounds like. You bet Team A and when it wins then you place the same amount on Team B. A parlay with two games going off at differing times is a type of "if" bet in which you bet on the first team, and when it wins you bet double on the second team. With a genuine "if" bet, instead of betting double on the second team, you bet the same amount on the second team.
It is possible to avoid two calls to the bookmaker and secure the current line on a later game by telling your bookmaker you want to make an "if" bet. "If" bets can also be made on two games kicking off as well. The bookmaker will wait before first game has ended. If the first game wins, he will put the same amount on the next game though it was already played.
Although an "if" bet is really two straight bets at normal vig, you cannot decide later that so long as want the next bet. Once you make an "if" bet, the next bet cannot be cancelled, even if the second game has not gone off yet. If the initial game wins, you will have action on the second game. Because of this, there is less control over an "if" bet than over two straight bets. When the two games you bet overlap with time, however, the only way to bet one only when another wins is by placing an "if" bet. Needless to say, when two games overlap in time, cancellation of the second game bet is not an issue. It ought to be noted, that when the two games start at different times, most books will not allow you to fill in the second game later. You need to designate both teams once you make the bet.
You can create an "if" bet by saying to the bookmaker, "I wish to make an 'if' bet," and, "Give me Team A IF Team B for $100." Giving your bookmaker that instruction would be the same as betting $110 to win $100 on Team A, and then, only when Team A wins, betting another $110 to win $100 on Team B.
If the first team in the "if" bet loses, there is no bet on the second team. No matter whether the next team wins of loses, your total loss on the "if" bet would be $110 once you lose on the initial team. If the initial team wins, however, you'll have a bet of $110 to win $100 going on the next team. In that case, if the second team loses, your total loss will be just the $10 of vig on the split of both teams. If both games win, you'll win $100 on Team A and $100 on Team B, for a complete win of $200. Thus, the maximum loss on an "if" would be $110, and the utmost win would be $200. This is balanced by the disadvantage of losing the entire $110, rather than just $10 of vig, each time the teams split with the initial team in the bet losing.
As you can plainly see, it matters a great deal which game you put first in an "if" bet. In the event that you put the loser first in a split, you then lose your full bet. If you split but the loser may be the second team in the bet, then you only lose the vig.
Bettors soon discovered that the way to avoid the uncertainty caused by the order of wins and loses is to make two "if" bets putting each team first. Rather than betting $110 on " Team A if Team B," you'll bet just $55 on " Team A if Team B." and create a second "if" bet reversing the order of the teams for another $55. The next bet would put Team B first and Team A second. This sort of double bet, reversing the order of exactly the same two teams, is named an "if/reverse" or sometimes only a "reverse."

A "reverse" is two separate "if" bets:
Team A if Team B for $55 to win $50; and
Team B if Team A for $55 to win $50.
You don't need to state both bets. You merely tell the clerk you intend to bet a "reverse," both teams, and the total amount.
If both teams win, the result would be the same as if you played a single "if" bet for $100. You win $50 on Team A in the initial "if bet, and $50 on Team B, for a complete win of $100. In the next "if" bet, you win $50 on Team B, and then $50 on Team A, for a total win of $100. Both "if" bets together create a total win of $200 when both teams win.
If both teams lose, the effect would also function as same as if you played a single "if" bet for $100. Team A's loss would cost you $55 in the first "if" combination, and nothing would look at Team B. In the second combination, Team B's loss would cost you $55 and nothing would go onto to Team A. You would lose $55 on each of the bets for a complete maximum lack of $110 whenever both teams lose.
The difference occurs when the teams split. Instead of losing $110 once the first team loses and the next wins, and $10 when the first team wins but the second loses, in the reverse you'll lose $60 on a split no matter which team wins and which loses. It works out in this manner. If Team A loses you will lose $55 on the initial combination, and have nothing going on the winning Team B. In the next combination, you'll win $50 on Team B, and also have action on Team A for a $55 loss, producing a net loss on the next combination of $5 vig. The loss of $55 on the first "if" bet and $5 on the next "if" bet offers you a combined lack of $60 on the "reverse." When Team B loses, you'll lose the $5 vig on the initial combination and the $55 on the second combination for exactly the same $60 on the split..
We've accomplished this smaller lack of $60 instead of $110 when the first team loses with no decrease in the win when both teams win. In both the single $110 "if" bet and the two reversed "if" bets for $55, the win is $200 when both teams cover the spread. The bookmakers would never put themselves at that sort of disadvantage, however. The gain of $50 whenever Team A loses is fully offset by the excess $50 loss ($60 instead of $10) whenever Team B is the loser. Thus, the "reverse" doesn't actually save us any money, but it has the benefit of making the chance more predictable, and avoiding the worry as to which team to place first in the "if" bet.
(What follows is link 789bet advanced discussion of betting technique. If charts and explanations offer you a headache, skip them and write down the guidelines. I'll summarize the guidelines in an an easy task to copy list in my next article.)
As with parlays, the overall rule regarding "if" bets is:
DON'T, if you can win a lot more than 52.5% or even more of your games. If you fail to consistently achieve an absolute percentage, however, making "if" bets once you bet two teams can save you money.
For the winning bettor, the "if" bet adds an element of luck to your betting equation it doesn't belong there. If two games are worth betting, then they should both be bet. Betting on one should not be made dependent on whether or not you win another. Alternatively, for the bettor who has a negative expectation, the "if" bet will prevent him from betting on the second team whenever the first team loses. By preventing some bets, the "if" bet saves the negative expectation bettor some vig.
The $10 savings for the "if" bettor results from the fact that he is not betting the second game when both lose. Compared to the straight bettor, the "if" bettor has an additional cost of $100 when Team A loses and Team B wins, but he saves $110 when Team A and Team B both lose.
In summary, anything that keeps the loser from betting more games is good. "If" bets decrease the number of games that the loser bets.
The rule for the winning bettor is strictly opposite. Anything that keeps the winning bettor from betting more games is bad, and for that reason "if" bets will definitely cost the winning handicapper money. Once the winning bettor plays fewer games, he's got fewer winners. Understand that next time someone tells you that the way to win would be to bet fewer games. A smart winner never really wants to bet fewer games. Since "if/reverses" work out a similar as "if" bets, they both place the winner at the same disadvantage.
Exceptions to the Rule - Whenever a Winner Should Bet Parlays and "IF's"
As with all rules, you can find exceptions. "If" bets and parlays ought to be made by successful with a positive expectation in only two circumstances::
If you find no other choice and he must bet either an "if/reverse," a parlay, or perhaps a teaser; or
When betting co-dependent propositions.
The only time I can think of which you have no other choice is if you're the very best man at your friend's wedding, you're waiting to walk down that aisle, your laptop looked ridiculous in the pocket of your tux so you left it in the car, you merely bet offshore in a deposit account without line of credit, the book includes a $50 minimum phone bet, you like two games which overlap with time, you pull out your trusty cell 5 minutes before kickoff and 45 seconds before you must walk to the alter with some beastly bride's maid in a frilly purple dress on your own arm, you try to make two $55 bets and suddenly realize you only have $75 in your account.
As the old philosopher used to say, "Is that what's troubling you, bucky?" If that's the case, hold your head up high, put a smile on your own face, look for the silver lining, and make a $50 "if" bet on your two teams. Needless to say you could bet a parlay, but as you will notice below, the "if/reverse" is a wonderful replacement for the parlay in case you are winner.
For the winner, the very best method is straight betting. Regarding co-dependent bets, however, as already discussed, there is a huge advantage to betting combinations. With a parlay, the bettor is getting the advantage of increased parlay odds of 13-5 on combined bets which have greater than the standard expectation of winning. Since, by definition, co-dependent bets should always be contained within exactly the same game, they must be made as "if" bets. With a co-dependent bet our advantage originates from the truth that we make the second bet only IF one of many propositions wins.
It could do us no good to straight bet $110 each on the favourite and the underdog and $110 each on the over and the under. We'd simply lose the vig regardless of how often the favorite and over or the underdog and under combinations won. As we've seen, if we play two out of 4 possible results in two parlays of the favorite and over and the underdog and under, we can net a $160 win when one of our combinations comes in. When to choose the parlay or the "reverse" when coming up with co-dependent combinations is discussed below.
Choosing Between "IF" Bets and Parlays
Predicated on a $110 parlay, which we'll use for the intended purpose of consistent comparisons, our net parlay win when among our combinations hits is $176 (the $286 win on the winning parlay without the $110 loss on the losing parlay). In a $110 "reverse" bet our net win will be $180 every time among our combinations hits (the $400 win on the winning if/reverse minus the $220 loss on the losing if/reverse).
Whenever a split occurs and the under comes in with the favorite, or higher comes in with the underdog, the parlay will eventually lose $110 while the reverse loses $120. Thus, the "reverse" has a $4 advantage on the winning side, and the parlay includes a $10 advantage on the losing end. Obviously, again, in a 50-50 situation the parlay would be better.
With co-dependent side and total bets, however, we are not in a 50-50 situation. If the favorite covers the high spread, it is more likely that the overall game will go over the comparatively low total, and if the favorite does not cover the high spread, it really is more likely that the overall game will under the total. As we have already seen, when you have a confident expectation the "if/reverse" is really a superior bet to the parlay. The actual possibility of a win on our co-dependent side and total bets depends upon how close the lines on the side and total are one to the other, but the fact that they are co-dependent gives us a confident expectation.
The point where the "if/reverse" becomes an improved bet compared to the parlay when coming up with our two co-dependent is really a 72% win-rate. This is simply not as outrageous a win-rate since it sounds. When coming up with two combinations, you have two chances to win. You merely have to win one out from the two. Each of the combinations has an independent positive expectation. If we assume the chance of either the favorite or the underdog winning is 100% (obviously one or the other must win) then all we are in need of is really a 72% probability that whenever, for example, Boston College -38 � scores enough to win by 39 points that the game will go over the full total 53 � at the very least 72% of that time period as a co-dependent bet. If Ball State scores even one TD, then we have been only � point from a win. A BC cover will result in an over 72% of the time is not an unreasonable assumption beneath the circumstances.
As compared to a parlay at a 72% win-rate, our two "if/reverse" bets will win a supplementary $4 seventy-two times, for a complete increased win of $4 x 72 = $288. Betting "if/reverses" will cause us to lose an extra $10 the 28 times that the results split for a total increased loss of $280. Obviously, at a win rate of 72% the difference is slight.
Rule: At win percentages below 72% use parlays, and at win-rates of 72% or above use "if/reverses."
