1- Having a positive mentality, ie beyond the small losses I will win, I aim to win the war even if I can lose a battle.


2 - Having the capital to develop the game we're going to do (with the general recommendations to reduce bets when losing, etc.)


3 - Having the patience and time to recover the small losses that are occurring without entering the "casino game" and start running to finish before you run out of gas.


4 - Not being stubborn. Stubbornness is the cardinal sin of the player.
The Simple Martingale or method of Garcia are two examples of the supposed infallibility of the progressions, unfortunately there are table limits that would prevent a player with unlimited capital to winning always, saved the fact that no one has unlimited capital.

That other Manrique post you did should be made compulsory reading for new members before they get in the forums....
