Unlike a professional who operates with ranges, an amateur thinks only about specific hands (his own and the opponent's) in each situation. However, poker is a game with incomplete information and it is almost impossible to narrow the opponent's range to one hand or combination.
The amateur repeats his mistakes.
Erroneous actions and incorrect judgments that are constantly repeated never bring good results at a distance. Simplifying the game, reducing it to only a few parameters, an amateur plays in the negative, while maintaining the confidence that he is simply unlucky. Often he tries to achieve something based only on his guesses, ignoring the facts.
But professionals always remember that they can make mistakes. Therefore, they try to constantly find and remove errors from their game.
