Considering that the biggest gripe of the WSP old-hands is that young players are ruining the game by relying too much on aggressive betting, I would like to argue that it is not nearly as much a game of skill as a lot of people think.
Tournament play is heavily influenced by luck. One bad beat and you're out. End of story.
Cash play, however, is a game of skill. A skilled player brushes off a bad beat, waits out the cold cards, and makes money in the long run. The overly aggressive risk-taker who just won a tournament will lose every penny of his winnings, and then some, if he chooses to sit down at a cash table and see how his playing style works for him in the long run.
You should really stop responding to peoples posts because its pretty clear that you have absolutely no idea what you're talking about. Luck is going to influence just about any game over a small sample size, thats why you have upsets in sports. However when you have a statistically relevant sample (in online poker this would be ~100k hands)you can fairly easily deduce who the skilled players are. I've been playing as my sole means of income since 2007, and have played well over a million poker hands(I played 5k in about 4 hours this evening) so I'm not just talking out of my ass.
