In my case, what I like most about playing poker is the great variation it has, the part of deception, intuition at certain times, and the possibility of being able to compete against people from all over the world and, in a few cases, create a friendship.
For me it is the challenge to beat other players in a Tournament, (nothing personal) It gives me a great feeling of achievement if I can get past the money bubble in a Game, Finish on the Final Table and then try and win it outright!
Each milestone in a game gives me more and more satisfaction, and it does not matter if I am playing for a few Cents in a Freeroll or a few Dollars in a buy-in game, Playing and finishing in the money is the main reward, Regardless of how much I am winning.
I could play in a game substituting Peanuts for chips, I would love to win all the nuts! but cannot eat them, and would finish up giving them all away at the end of the game.
