In various sources, this strategy may be called betting corridors, pants, middles (there is a term middle in English-speaking sources) - it is a derivative of the fork and the standard bet. The similarity with a bookmaker's fork is that a corridor is a combination of two opposite outcomes of the same event.

The difference from the fork - the corridor consists of two bets that can win together, if a certain outcome occurs. Another nuance - in contrast to a fork, a corridor does not guarantee profit regardless of the outcome.

Let's analyze a concrete example. The player makes overlapping bets on a hockey match: total over 4.5 and total less than 6.5. If the total is less than or equal to 4, only the second bet wins, the first one loses. If the total is more or equal to 7, the first bet wins, the second loses.

Partially losses from losing are compensated by winning. If the total is 5, 5.5 or 6, both bets win. The outcome, when the corridor gives a profit on both bets, is called getting inside the corridor. The set of outcomes in which such hitting occurs are corridor outcomes.

## How to find a corridor?

**To find a corridor that can work, it is necessary to find two bets that meet several conditions:**

Regardless of the outcome of the event, at least one bet wins. Bets have an overlapping range of events in which both bets can win, or one partially wins, the other provides a return. The odds are selected in such a way that at any outcome outside the corridor the player loses a small amount of money.

To find a corridor, it is necessary to collect and analyze the lines of the maximum number of bookmakers' offices like https://1xbet-tounes.com/, go through all variants and combinations, calculate at what outcomes the above conditions are met. Given that the data on bets and odds quickly become outdated, calculations and analysis are carried out as quickly as possible.

## Types of Corridors

**Corridors are classified according to a number of characteristics:**

The types of bets involved in the corridor. There are corridors of the type "total - total" and "handicap - handicap. For example: TB 3.5 - TM 5.5, F1(2.5) - F2(-0.5). Behavior of the bets in the corridor:

Both bets can win. One of the bets wins, on the other there is a refund. Example: F1(0) - F2(0.5). In case of a draw, the second bet wins, the second bet is refunded. Both bets partially win. Ф1(0.25) - Ф2(0.25). In case of a draw both bets partially win. One bet wins partially and a refund is made on the other. Ф1(0) - Ф2(0.25). In case of a draw, the first bet and half of the second bet are returned, on the half of the second bet the win is accrued.

## How to Evaluate the Corridor

To understand whether it's worth risking your money for a chance to win a little more, you need to estimate the probability of hitting the corridor. If you multiply the probability by the odds and get more than one, there is a good chance of getting into the corridor.

To estimate the probability of getting into the corridor, add the probabilities of occurrence of each outcome present in the corridor, and subtract from the resulting sum of 100 percent.

Do not bet on all the corridors in a row - among them there are both overvalued and undervalued.

## Advantages and disadvantages of playing on the corridors

Corridors are closely related to forks and overbetting, so they include the main pros and cons of these systems.

**Advantages:**

The possibility of big winnings with a small amount of bets. Corridors are much more common than forks. Playing on corridors guarantees a small win in any outcome and a big win if you hit a corridor.

**Disadvantages:**

Overvalued corridors are quite rare. At the same win in the long run is guaranteed only when betting on overvalued corridors. Before betting, it is necessary to analyze all data, check all corridor shoulders for compliance with the limits, etc.
