SkillYour skill, i.e. your talent or your abilities, contrasts with the element of luck in poker. The bigger your skill, the less your poker success depends on luck or chance.
A player without any skill may very well see some short term success. However, this would only be due to chance, since this player is not strategically using his abilities in order to play a profitable poker game.
The skill of a poker player basically includes many abilities that are essential to beating the game in the long run, for example the right starting hand selection, a good table selection, an appropriate bankroll management as well as the player's mindset and tilt resistance.
