"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 know how to bet an "if/reverse." A complete explanation and comparison of "if" bets, "if/reverses," and parlays follows, along with the situations where each is best..
An "if" bet is exactly what it sounds like. Without a doubt Team A and when it wins you then place an equal amount on Team B. A parlay with two games going off at different times is a type of "if" bet in which you bet on the first team, and if it wins you bet double on the next team. With a true "if" bet, instead of betting double on the next team, you bet the same amount on the second team.
You can avoid two calls to the bookmaker and lock in the current line on a later game by telling your bookmaker you want to make an "if" bet. "If" bets can be made on two games kicking off at the same time. The bookmaker will wait until the first game is over. If the initial game wins, he will put the same amount on the second game even though it has already been played.
Although an "if" bet is actually 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 second bet can't be cancelled, even if the second game has not gone off yet. If the initial game wins, you will have action on the next game. For that reason, there is less control over an "if" bet than over two straight bets. When the two games you bet overlap in 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 with time, cancellation of the next 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 complete the next game later. You must designate both teams when you make the bet.
You can make an "if" bet by saying to the bookmaker, "I want to make an 'if' bet," and then, "Give me Team A IF Team B for $100." Giving your bookmaker that instruction will be the identical to betting $110 to win $100 on Team A, and then, only if 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 second team wins of loses, your total loss on the "if" bet will be $110 once you lose on the first team. If the first 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 the two teams. If both games win, you'll win $100 on Team A and $100 on Team B, for a total win of $200. Thus, the maximum loss on an "if" will be $110, and the maximum win will be $200. This is balanced by the disadvantage of losing the entire $110, instead of just $10 of vig, each time the teams split with the first team in the bet losing.
As you can see, it matters a good deal which game you put first in an "if" bet. If you put the loser first in a split, then you lose your full bet. In the event that you split but the loser is the second team in the bet, then you only lose the vig.
Bettors soon discovered that the way to steer clear of the uncertainty caused by the order of wins and loses would be 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 make a second "if" bet reversing the order of the teams for another $55. The second bet would put Team B first and Team Another. This kind of double bet, reversing the order of 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 have to state both bets. You only tell the clerk you want to bet a "reverse," both teams, and the amount.
If both teams win, the result would be the identical to if you played an individual "if" bet for $100. You win $50 on Team A in the first "if bet, and then $50 on Team B, for a complete win of $100. In SV66 "if" bet, you win $50 on Team B, and then $50 on Team A, for a complete win of $100. Both "if" bets together create a total win of $200 when both teams win.
If both teams lose, the result would also be the same as if you played an individual "if" bet for $100. Team A's loss would cost you $55 in the first "if" combination, and nothing would go onto Team B. In the second combination, Team B's loss would cost you $55 and nothing would look at to Team A. You would lose $55 on each one of the bets for a total maximum lack of $110 whenever both teams lose.
The difference occurs once the teams split. Rather than losing $110 once the first team loses and the next wins, and $10 when the first team wins however the second loses, in the reverse you will lose $60 on a split no matter which team wins and which loses. It works out in this manner. If Team A loses you'll lose $55 on the first combination, and have nothing going on the winning Team B. In the second combination, you'll win $50 on Team B, and have action on Team A for a $55 loss, producing a net loss on the second mix of $5 vig. The increased loss of $55 on the first "if" bet and $5 on the next "if" bet gives you a combined lack of $60 on the "reverse." When Team B loses, you'll lose the $5 vig on the first combination and the $55 on the next combination for exactly the same $60 on the split..
We have accomplished this smaller loss of $60 rather than $110 once the first team loses with no decrease in the win when both teams win. In both single $110 "if" bet and both reversed "if" bets for $55, the win is $200 when both teams cover the spread. The bookmakers could not put themselves at that type 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 does have the advantage of making the chance more predictable, and avoiding the worry as to which team to put first in the "if" bet.
(What follows can be an advanced discussion of betting technique. If charts and explanations offer you a headache, skip them and simply write down the guidelines. I'll summarize the rules in an easy to copy list in my next article.)
As with parlays, the general 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 cannot consistently achieve a winning percentage, however, making "if" bets once you bet two teams will 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, they should both be bet. Betting on one should not be made dependent on whether you win another. On the other hand, for the bettor who includes a negative expectation, the "if" bet will prevent him from betting on the next 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 truth that he could be not betting the second game when both lose. When compared to straight bettor, the "if" bettor comes with an additional expense 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 reduce the amount 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 has fewer winners. Understand that next time someone tells you that the best way to win would be to bet fewer games. A smart winner never really wants to bet fewer games. Since "if/reverses" workout 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, there are exceptions. "If" bets and parlays should be made by successful with a confident expectation in only two circumstances::
When there is 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 that you have no other choice is if you're the best man at your friend's wedding, you're waiting to walk down the aisle, your laptop looked ridiculous in the pocket of one's tux and that means you left it in the automobile, you merely bet offshore in a deposit account without credit line, the book has a $50 minimum phone bet, you like two games which overlap with time, you grab your trusty cell 5 minutes before kickoff and 45 seconds before you need to walk to the alter with some beastly bride's maid in a frilly purple dress on your arm, you try to make two $55 bets and suddenly realize you merely have $75 in your account.
As the old philosopher used to say, "Is that what's troubling you, bucky?" If so, hold your mind up high, put a smile on your face, look for the silver lining, and make a $50 "if" bet on your own two teams. Of course you could bet a parlay, but as you will see below, the "if/reverse" is a good substitute for the parlay in case you are winner.
For the winner, the best method is straight betting. Regarding co-dependent bets, however, as already discussed, there exists a huge advantage to betting combinations. With a parlay, the bettor gets 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 among the 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 would simply lose the vig no matter how usually 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 among our combinations comes in. When to find the parlay or the "reverse" when making co-dependent combinations is discussed below.
Choosing Between "IF" Bets and Parlays
Based on a $110 parlay, which we'll use for the purpose of consistent comparisons, our net parlay win when one of 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 would be $180 every time one of 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 over will come in with the underdog, the parlay will lose $110 while the reverse loses $120. Thus, the "reverse" includes 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 will be better.
With co-dependent side and total bets, however, we have been not in a 50-50 situation. If the favorite covers the high spread, it really is much more likely that the game will review the comparatively low total, and if the favorite fails to cover the high spread, it is more likely that the game will beneath the total. As we have previously seen, when you have a confident expectation the "if/reverse" is really a superior bet to the parlay. The specific probability of a win on our co-dependent side and total bets depends on how close the lines privately and total are one to the other, but the proven fact that they're co-dependent gives us a positive expectation.
The point where the "if/reverse" becomes a better bet than 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 making two combinations, you have two chances to win. You only have to win one out from the two. Each one 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 a 72% probability that when, for instance, 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 away from a win. A BC cover will result in an over 72% of the time isn't an unreasonable assumption beneath the circumstances.
In comparison with 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" may cause us to lose a supplementary $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."
