Is poker gambling?

[roxtar]

A buddy of mine got into a discussion the other day about whether or not poker is a form of gambling. I say it is not due to the fact that there are definate mathmatically correct ways to play the game that if followed correctly = a long term win (+EV).
He hasn't gone so far as to say it's a game of TOTAL chance such as the lottery or bingo but he claims there's way too much chance involved to make it a game of skill.

Just wondering what you guys thought.
