Wait for 2 decisions in a row that are the same (pass or don't). Bet one unit on the same decision as the previous two. There are no place bets and no odds bets.
If that first bet wins, bet another one unit on the SAME side that has been winning. Keep going until this loses. When it loses, then bet 3 units on the OPPOSITE side from the previous 1 unit bet(s). You are betting that the different side will repeat. Then...
a) If this 3 unit bet wins, then go back to a 1 unit bet on the SAME side as the WINNING 3 unit bet. If THIS 1 unit bet wins, then keep betting the 1 unit on the same side. When THIS 1 unit bet loses, wait until the side changes AND there are 2 decisions that are the same. THEN start over with a 1 unit bet on the same side as the 2 same decisions (see above). Note that you do not revert to another 3-unit bet!
b) ON THE OTHER HAND, if the original 3 unit bet loses, then wait until the side changes AND there are 2 decisions that are the same. THEN start over with a 1 unit bet on the same side as the 2 same decisions (see above). Note that you do not revert to another 3-unit bet!
