This is another system opposite (like the Anti-Martindale), but it applies
to the D'Alembert. With this one, you increase after every win, and decrease
after every loss.
Because it offers reasonable protection of the downside, it is one of
the better ones to try (if you're determined to play systems), because
when the losses come, your bets regress to the base level, where they
will stay until the wins return.
It's not a bad way to exploit a winning run, if it is used as a sporadic
technique. In fact, I have been known to employ betting schemes that are
based around this concept!
