Of course, each person according to what they can offer, everything has a value, the only thing is that there are currently many tools to learn to play poker, I would be much more inclined because all this also has to be done some practices in full course, because the experience is everything in poker, I think there are many scenarios in each game, in each decision, that is where the professionalism of the player is seen, and that he supports any circumstance that requires him to make decisions under a high-pressure scheme and where manage money, a lot of money or a little, in the same way that you learn to make the best decision.
As i Know, there not so much working patterns against few types of users. Which will help you to win on the long run. So when two close-skilled players are playing against each other, mostly luck depends.
If you want more practice, you don't need any courses.
You wont really need any courses yet everything could be find on the net if ever if you are finding for some theories but the rest would be depending on the experience on applying those ideas and theories that you had
learned up and making yourself more better or good will really be needing that experience which via on dealing against other players.
