100 percent skill?? Thats absurd. Luck plays a bigger part than any "skillful" player wants to admit. Lets say you have AA, You make large raise, not to large now, because with your skill you don't want to run everyone off. You get one caller,the flop comes 2JK...he checks you bet large,..he folds. You are lucky he didn't flop a set of Js, or a set of Ks, or KJ...or worse, a set of 2s. Poker is about who makes the least amount of mistakes, plays the hands to the best of thier advantage,
odds, outs etc...chip management,
bluffing, reading and instinct. But every call, every flop...and every all in, especially pre flop, depends on luck!! You think that Gus hansen calling an all in with KJo, against KQ suited and hitting a J on a cold board to win is because of his skill?? it takes skill to be a good player, but luck plays a huge part in every hand, Iwould conservitively say 50/50.
