Hello, I think that the fact of "mastering poker" is something very complex to calculate, you can learn the rules quickly in a matter of days, you can believe that you learned enough over the months, but the reality is that for Being a winner and considering that the game is mastered is a very long process that, according to my point of view, is achieved by players who play at high levels, even so the game is constantly evolving which produces that the player who stops studying and seeks to improve his game can't keep up.
