This is bascially same strategy playing with 5 streets with a progressive bet, and a negative +1 progression.
First 3 streets are placed at either High or Low. Alternating... (with 1 space in between) 1u bet.
Next, 1 more street is placed next to the others, with one space in between. 1u bet
Last, 1 more doublestreet is placed, next to the others. (one space in between) 2u bet
Now for each loss +1u bet, until hit. (this progression is not perfect) It will be used anyway, either bankroll is positive of negative... one trick that could be used IS not to reset after one hit, continue progression until bankroll is positive, then reset.
This is risk/reward...
Reset/Restart. (Reset at any stage 1 hit)
