The Labouchere Betting System is under the negative progression system. Also called Cancellation, Cross out, Labby and Split Martingale. This betting system has different variations, we'll try to go over the most simple structure of this betting system for blackjack players.
To illustrate this system, before starting to play, write a string of random numbers, this set of numbers can be short or long and not necessarily sequential. The choice depends on the type of game you want this system to apply and the odds of the bet.
For example, lets say the series of numbers is 1 3 1 4 4 1 6 5. Bettors will start by adding the first and last numbers in the series. In this example, bettors will gamble 6 units (1 and 5) as initial bet. If this initial bet happens to win, cross out the numbers and move on to the next two outside numbers. Using this example, the next bet would be 9 units (3 and 6), and so on.
In gambling we all know that we can't win every hand. When the player lose the initial bet of 7 units (1 and 6) The player must add the sum of what is lost into the end of the series instead of crossing out the two numbers. So now, taking this example given above the series will look like 1 3 1 4 4 6 5 6. The next bet for the players will be 7 units (1 and 6).
The reverse of this system turns it into a positive progression system. Meaning, if bettors lose, it is not necessary to bet more to win their money back. In this case, if the bettors win they will add the numbers to end of the series instead of crossing out the outside numbers. If they lose, that the time to cross out the numbers and move to next outside numbers.
The Labouchere System betting system is rather simple method and very easy to use. Players will know that they succeed if all the numbers in the series are being crossed out. The downside of this betting system is if a player is in the losing streak, players will bet more and more when they lose a hand. This system requires a huge bankroll.
But despite this, it is still recommended over martingale for the reason that in the martingale betting system players will start with more larger bankroll because they have to double the bet after losing a hand. Using the Martingale betting system, it is more likely to stay in the game for a matter of minutes. Meanwhile, labouchere system allows the player to stay longer in the because they will not doubling up their bets everytime they lose a hand
