Hello Azim. Welcome to the forum. Very good and important observation. I think along the same lines as well. If you get the opportunity, I have posted a pdf file of the book " Ten Days at Monte Carlo at the Banks Expense" in my section of the forum. There is a couple of the pages that coincide with your way of thinking.
To quote the book, "A very essential point about a good system is simplicity. The more elaborate and complicated your system may be, the more certain it is to fail. There is no doubt that the croupiers will be on the look-out for the moment when you begin to get into deep water, and then, by spinning quicker than usual, they will prevent your working out any elaborate calculation to arrive at the amount to be staked. They will flurry and bustle you, and endeavor to make you lose your head and your temper, at critical moment, and from what I have seen myself and from what players themselves have told me, it is very certain that they often succeed.
It is no use people attempting to play a system unless they are specially qualified to undertake it. A few indispensable qualities are, a clear head, unlimited faith in the system, dogged perseverance, the best of good tempers, and plenty of pluck. Anyone who does not possess all of the above qualifications, in addition to a few others, had better leave systems alone; for to play a system impatiently, timidly, or with insufficient capital is quite the surest way to lose."
"Most systems fail because the stakes are increased too quickly: the player gets into big figures, strikes a run against himself, and is either defeated by the maximum, or from want of capital."
"The fact of the matter is that he is too greedy, and has not the sufficient patience. If he commences by losing, he is in too much of a hurry to get his money back. If he wins, at first, he stays on at the tables too long and exhausts his good luck, winning small sums, and when the bad luck sets in, he begins playing high stakes and losing."
I agree with what you say. I am a firm believer in that we should plan ahead of time when to play and when to walk away. My golden rule when I play is that my goal is to win just 10% of my bankroll. That's it. Most people laugh at this idea. They all expect to double their capital, and most of them hope to make 400-500%. But the bank in a good year only makes about 1% a week and about 50% for the year. That is still a huge gain. To put in another perspective, if we play once a month, that is 10% a month multiplied by 12 months in a year is 120% return on your investment. Most investments in the stock market at best are 25 to 30%. This makes us dangerous players when we play this way. Because unlike the bank, we can get up and walk away whenever we want.
Very nice observation and keep up the good work and once again welcome to the forum.
