There is a skill element to playing poker, which starts with you having control over which cards to play and which to fold. In addition, poker skill is required to put opponents on a range of hands, to bet the correct amount of chips to induce a call or fold, and more.
Well, in the short run as much as 80% of poker can be luck but in the long run it is pretty much 100% skill. This is because the math plays itself out and luck no longer plays a significant role at all. So it is important that you are ready for the short term variance in poker.
