so there is luck, but I think that skills that are important in the long term, many players have proven themselves in this game, the more you play the more important decisions you have to make, but to set an example with Daniel Negreanu, he has wins in huge tournament, I do not believe that this is just luck and not only he, as I and other players to get back on their luck if you have AA and your opponent's 44 and the flop is 445, certainly had no luck with your AA but here we can go further back and see his actions before the flop, then maybe there is a bad play by AA, but if you did everything right, just bad luck, but when it's in the long run, I think that will often beat the player who has the skills !!!
