Labouchere:
This is also known as the
cancellation system. Pick a series of numbers, say 1,2,3,4,5. Your first bet is
the total of the two numbers on the end, or 6 units in this case. If you lose
it, you cancel out the 1 and the 5, add the six to the end of the series and bet
the 6 and the 2, for a total of eight units bet. Lose that one and you add the
eight to the series, cancel the 2 and the six and bet a total of 11 (3+8) and so
on. If you win, you proceed to the inside numbers until they are all cancelled
out. Again, a loser, but an insidious one.
"31" system:
This system has many
variations. Instead of relying on one win to get you back in the black, it
relies on two. The "31" system takes its name from the total number of
units in the series. The progression goes: 1-1-1-4-8-16. If you lose, go to the
next step. If you win, double the last bet. If you win that, start all over, if
you lose, go to the next step. This type of double-up progression can come in
many guises, but the principle is the same. A bad way to lose good money.
2-5 System:
This system says you only have
to win 40% of your bets to come out ahead or nearly so. Now we're talking! The
series is designed with five numbers. Win any two of them and you've won the
series and you can start over. An example would be 5-7-12-15-25. Win any two in
that series and its over. Its still a loser. Wait until you've hit the last bet
in the series and you lose a double down hand. Ouch!
