I have to agree with The Bartender. Way too dangerous.

Even if you split your bankroll to X series and start wagering, after some time you fill find yourself down on many of them or all of them. It is nothing unusual to have 10 losing bets in a row. Or 15. It doesnt happen every week or every month and it can wait for you after maybe a year of using this "system", but when it comes, it will destroy your BR quickly not to mention hardly earned winnings. Plus I wonder who will enjoy laying many thousands dollars to win just a couple of hundreds.

The problem is that when you are in HOT streak, you are still winning just small money, because THEN you are NOT doubling the profits to make bigger stakes. Go with 15 winners in a row and you earn some small money. Then go with 15 losses in a row - DISASTER. Thats just the sad fact.

@thopaul75: Your saing about gaining the edge over bookies is not true. The edge is still with bookies, because of their odds. You are still wagering -110 lines, not 100. So you always risk more to win less. Now even if you dont need to win every second bet to be profitable, you are just replacing the needed winning ratio with bigger stakes - and bookies will love you at least the same. Otherwise, you could go to casino and simply apply the same to roulette betting - think that "ZERO" number is the edge of the casino - same as -110 lines. Noone ever won there long-term unless there were some forecastable conditions (table, ball condition etc.).

When doubling up (or adding some part of it) after loosing bet you will find yourself very quickly in position when you will be forced to lay huge amount just to break even or win small.

That sucks. But good luck to everyone willing to try.

Personally, I believe in finding value in odds. That is the only possibility to beat bookies in the long run. But even with that value, you cannot avoid loosing streaks. Noone can.
