# Blackjack – La Bouchere System

Also known as the cancellation system, the Labouchere system is additive in nature. A sequence of numbers, say 1,2,3,4, is chosen. The first bet is the total of the two numbers on the end, or 5 units in this example. If the bet is lost, the lost bet now becomes the last number of the new sequence,1,2,3,4,5. The next bet is now the sum of the new first and last numbers. In the above example, 6. If the bet is won, the first and last numbers in the sequence are canceled, in this case with the sequence 1, 2,3,4, the 1 and 4 are canceled, and, the next bet is the sum of the two non-canceled numbers, 2 and 3. If you win, you proceed to the inside numbers until they are all canceled out. Again, a loser, but an insidious one.
