There are other ways to deploy a martingale type strategy without doubling down after each loss. For example, one could double down only after three consecutive losses. Or better yet, one could vary the size increase relative to the number of consecutive losses. For example, after each loss, increase size by 1 unit; however, after five consecutive losses, increase size by doubling down. With a Semi-martingale approach, once could be net positive with a 40% - 43% win rate. Needless to say, with a 20% discount on losses, won would easily have a positive expectancy while winning less than 40%. Walt
Correct.....and you can also dynamically grow bet size into strings of winners. I know of two players that stay low key out in Vegas but have what I call "perpetual motion" money management strategies. I don't know all their details but "I get" what they are doing.
I think we are in the age where solid BJ play mixed with capital and an asymetrical money management style may be pushing the envelope of the game......and that is VERY COOL!
If your going to use a martingale strategy, your less likely to hit your max bet with odds in your favor even if risk:reward isn't. for example in roulette if you bet on red or black, odds of winning are 50%, with a 1:1 win:loss payout. Betting on 2 out of 3 dozen has a 1:2 win:loss payout but has a 66% chance of winning. so lets say you wait for the wheel to hit "dozen B" 3 times in a row, then using martingale you bet on dozens A and C for up to 5 spins, its not likely that "dozen B" will get hit 8 times in a row.
As they say in trading test out your ideas. Here is a Blackjack Strategy Trainer. test out your martingale ideas. do it after the trading day, because it is addictive! http://www.blackjackinfo.com/bst/
Why would a pro gambler get involved at this level unless he HAD AN EDGE? He wouldn't. But it's not clear what it was.
