I hear some people state positive progressions like ‘1-2-4-8’, and they say if you lose the 3rd parlay/progressive you ‘ONLY’ lose the one unit. I still endorse and recommend the one that has been highly successful for myself, which is the 1-3-2-6 positive progression and here is why:
If you get past the 2 parlay/progression, which IMO is the hardest one psychologically to get past, you will have the 3rd one, the one with the 6 units, on the house to wager. If you lose the last one, you have lost nothing from you buy-in/bank roll. Yes, you will have 2 units in this on the second wager, but if you prevail and win that one, you have your 2 units returned and the 3rd wager is on the house if you lose that one. You will have your 2 units back and a profit of 2 units even if you lost the 3rd progression with the 2 units out there. And the 2 units you have profit is your funding for the next attempt!
I watch so many players with their Marty’s and their 1/2/3 and then 2/4/6 and then 4/8/12, etc., and when they lost quickly they are eating into their buy-ins and bank rolls. Whatever, it’s all good if you are that arrogant.
To me, this is a no brainer, play smarter, NOT HARDER!
Coupled with my ‘1 + 4’ Side Wager Parlay and my 1/3rd, 1/3rd, 1/3rd Money Management system, I never lose IF I won, never. And those simple ‘non mechanical system’ events---can and will assist you more than anything else in this volatile game especially if you won.
