This strategy is a negative betting progression that is sometimes called a Cross Out system. There are several variations of it. You just need to write a row of figures in the simplest version of this strategy. They may be located in sequence (1, 2, 3, 4, 5, 6) or randomly (1, 1, 2, 2, 2, 4, 5). The length of this row can vary significantly, but it is believed that it should be short for successful results. Its type depends on the kind of games in which you want to use it and the difference between the minimum and maximum bets available at your table.
Each figure represents a certain bet or number of chips. You should bet the first and last number added together. For example, your row is 1, 2, 3, 4, 5, 6, 7, 8. Your first bet is 1+8 = 9. If you win, you need to cross out 1 and 8 and bet the numbers that have become terminal, i.e. 2+7=9. If you win again, cross out these numbers and wager 3+6=9 (in our example, the bet size remains the same, but if the row is composed of inconsequently increasing numbers, it will look in another way.) Start again when you cross all numbers off the row.
You will not succeed in winning every time, so after a lost hand or spin add to the end of your rows of numbers a figure that is equal to the lost bet. In this example, it is 9 after the first loss. Then next bet that you will make is equal to 1+9=10. If you lose in this case, add 10 to the list and wager 1+10=11. This is the main principle of the Labouchere betting strategy.
To be sure, if you are able to cross off the whole list, you will surely be in the black. However like in most other systems, if you have a series of losses even if you have started with the lowest possible bet, you will very quickly have to stake large sums that may exceed the upper table limit. If this happens, the strategy loses its efficiency.
Anti-Labouchere Betting Strategy
Instead of the lost bets it is necessary to add winning numbers to your sequence. After each victory add the bet amount to the end of your list. If you lose, cross out two terminal figures. Select a certain number that you want to reach as your aim. For example, it may be twenty or thirty chips while playing on equal chances or less if you wager on columns or dozens. Having reached this aim, you should start from the beginning. Having lost, it is no doubt that you should start again. Initially, select a short row (for instance, 1, 2, 3, 4).
In fact, this system hardly seems to be more efficient than the basic Labouchere betting strategy, since everything depends on how quickly a win will occur. Even several losses at the beginning make you start again.
There are also other variations of the Labouchere betting strategy, but they do not differ fundamentally from the two basic variants. This system has gained popularity among fans of roulette, since it provides the prolonged winning sessions under favorable circumstances.
It should be kept in mind that most casinos do not allow to make any notes at the table, so that the Labouchere betting strategy is mainly suitable for online gambling.
