"IF" Bets and Reverses
I mentioned last week, that when your book offers "if/reverses," it is possible to play those instead of parlays. Some of you may not discover how to bet an "if/reverse." A complete explanation and comparison of "if" bets, "if/reverses," and parlays follows, together with the situations where each is best..
An "if" bet is exactly what it sounds like. You bet Team A and IF it wins you then place the same amount on Team B. A parlay with two games going off at different times is a type of "if" bet where you bet on the initial team, and when it wins without a doubt double on the second team. With a true "if" bet, instead of betting double on the second team, you bet an equal amount on the next team.
You can avoid two calls to the bookmaker and lock in the current line on a later game by telling your bookmaker you would like to make an "if" bet. "If" bets may also be made on two games kicking off at the same time. The bookmaker will wait until the first game is over. If the first game wins, he'll put an equal amount on the next game though it was already played.
Although an "if" bet is actually two straight bets at normal vig, you cannot decide later that so long as want the second bet. Once you make an "if" bet, the second bet can't be cancelled, even if the second game have not gone off yet. If the initial game wins, you will have action on the next game. Because of this, 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. Of course, when two games overlap with time, cancellation of the next game bet is not an issue. It should be noted, that when the two games start at differing times, most books will not allow you to fill in 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, "Give me Team A IF Team B for $100." Giving your bookmaker that instruction would be the identical to betting $110 to win $100 on Team A, and, only if Team A wins, betting another $110 to win $100 on Team B.
If the initial team in the "if" bet loses, there is no bet on the next team. Whether or not 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 first team wins, however, you would 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 would win $100 on Team A and $100 on Team B, for a complete win of $200. Thus, the utmost 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 great deal which game you put first in an "if" bet. If you put the loser first in a split, you then 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 found that the way to avoid 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 would 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 A second. This sort of double bet, reversing the order of the same two teams, is named an "if/reverse" or sometimes just 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 wish to bet a "reverse," the two 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 initial "if bet, and then $50 on Team B, for a complete win of $100. In the next "if" bet, you win $50 on Team B, and $50 on Team A, for a complete win of $100. The two "if" bets together create a total win of $200 when both teams win.
If tdtc lose, the result would also be the same as if you played a single "if" bet for $100. Team A's loss would cost you $55 in the initial "if" combination, and nothing would look at Team B. In the second combination, Team B's loss would set you back $55 and nothing would look at to Team A. You would lose $55 on each of the bets for a complete maximum loss of $110 whenever both teams lose.
The difference occurs once the teams split. Instead of losing $110 when the first team loses and the second wins, and $10 when the first team wins however the second loses, in the reverse you'll lose $60 on a split no matter which team wins and which loses. It works out this way. If Team A loses you'll lose $55 on the first combination, and have nothing going on the winning Team B. In the next combination, you'll win $50 on Team B, and have action on Team A for a $55 loss, resulting in a net loss on the second combination of $5 vig. The increased loss of $55 on the first "if" bet and $5 on the second "if" bet offers you a combined lack of $60 on the "reverse." When Team B loses, you will 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 without reduction in the win when both teams win. In both the single $110 "if" bet and both 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 extra $50 loss ($60 rather than $10) whenever Team B may be 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 concerning which team to put first in the "if" bet.
(What follows is an advanced discussion of betting technique. If charts and explanations provide you with a headache, skip them and simply write down the guidelines. I'll summarize the guidelines in an easy to copy list in my own next article.)
As with parlays, the general rule regarding "if" bets is:

DON'T, if you can win more than 52.5% or more of your games. If you fail to consistently achieve an absolute percentage, however, making "if" bets whenever 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. However, for the bettor who has a negative expectation, the "if" bet will prevent him from betting on the second team whenever the initial 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 is not betting the next 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, whatever keeps the loser from betting more games is good. "If" bets decrease the amount of games that the loser bets.
The rule for the winning bettor is exactly opposite. Anything that keeps the winning bettor from betting more games is bad, and for that reason "if" bets will 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 is to bet fewer games. A smart winner never wants to bet fewer games. Since "if/reverses" workout exactly the same as "if" bets, they both place the winner at an equal disadvantage.
Exceptions to the Rule - When a Winner Should Bet Parlays and "IF's"
Much like all rules, you can find exceptions. "If" bets and parlays ought to be made by a winner with a confident expectation in mere two circumstances::
When there is no other choice and he must bet either an "if/reverse," a parlay, or 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 very best man at your friend's wedding, you are waiting to walk down that aisle, your laptop looked ridiculous in the pocket of one's tux and that means you left it in the car, you merely bet offshore in a deposit account with no 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 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 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 own two teams. Needless to say you could bet a parlay, but as you will notice below, the "if/reverse" is an excellent substitute for the parlay when you are winner.
For the winner, the 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 gets the advantage of increased parlay probability of 13-5 on combined bets which have greater than the standard expectation of winning. Since, by definition, co-dependent bets must always be contained within exactly the same game, they must be produced as "if" bets. With a co-dependent bet our advantage comes from the point that we make the second bet only IF among the propositions wins.
It would do us no good to straight bet $110 each on the favorite and the underdog and $110 each on the over and the under. We'd simply lose the vig regardless of 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 favourite and over and the underdog and under, we are able to net a $160 win when one of our combinations will come in. When to find 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 purpose of consistent comparisons, our net parlay win when among our combinations hits is $176 (the $286 win on the winning parlay minus 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 without the $220 loss on the losing if/reverse).
When a split occurs and the under will come in with the favorite, or higher comes in with the underdog, the parlay will lose $110 as the reverse loses $120. Thus, the "reverse" has a $4 advantage on the winning side, and the parlay has 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 are not in a 50-50 situation. If the favourite covers the high spread, it really is more likely that the game will review the comparatively low total, and if the favorite does not cover the high spread, it is more likely that the game will under the total. As we have already seen, when you have a positive 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 on how close the lines privately 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 a better bet than the parlay when making our two co-dependent is 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 only have to win one out of your two. Each one of the combinations has an independent positive expectation. If we assume the opportunity of either the favourite or the underdog winning is 100% (obviously one or the other must win) then all we need is a 72% probability that when, for instance, Boston College -38 � scores enough to win by 39 points that the overall game will go over the full total 53 � at 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 can lead to an over 72% of that time period isn't an unreasonable assumption under the circumstances.
As compared 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 outcomes split for a complete increased lack 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."
