I believe that a person who is looking for strategies should use them all, that is, not stick with just one but use all the ones that are learned or investigated, because what he always gave me to understand in a casino game is that a pattern that is repeated the chances of losing are much higher.
I also agree with you that a person must use all the strategies he knows but I do not think that it will help that much without considering the length of time of his session. I think we all agree that having a long session of gambling activity always triggers house edge and a series of redstreaks. Even with different strategy apply on a session, eventually, if we keep on playing, the casino will catch up making it hard for us to win no matter what our strategy is. So I think the use of strategy should be integrated with time length. The shorter we play in a casino the lesser we have to encounter long series of red streaks.
Very interesting comment but I do not think the effect is that direct. I think the key takeaway from this should be that good strategies need discipline and finally, always know your max - the most you can afford to lose. Its easy to get blinded by the thrill of winning, but its important to remember that gambling is always a game of probabilities and there will be times when the odds are not in your favor. In other words, it is crucial to know when to stop gambling.
