Not too shabby for a "game of chance", if you ask me.

Which brings me to my challenge for the BTP community. All of us know that poker is a game of skill, and indeed most of the sites that are remaining in the US are taking that stance as well. However, I believe that most of the public at large (and certainly the US Congress) views poker as a game of chance. And they're right....
it all comes down to how you define the word "win" as it relates to the game of poker.
If you define "win" to mean winning a particular hand, then poker is a game of chance - with the exception of getting everyone else to fold before showdown, skill plays no part in the outcome of a single hand. Even for a single session, skill doesn't play a large role - we've all seen fish who play like crap and clean house, while we play our A game and still finish in the red.
And yet we still consider poker a game of skill... The problem is that I can't think of a concise (one that could be understood even by legislators) definition of "winning" that would make it clear that poker is indeed a game of skill.
How do you define "winning at poker" in such a way that it's clear to a non-poker player that poker is a game of skill?
