Loosing players have a negative EV because some players are better than them. But poker is a +EV game for decent players.

I lived two years from poker and one year in Phuket Thailand. I'm not the best player around but I've studied the game a lot and I think everybody with two neurons can do that.

You can study craps or roulette for a year, you will still lose in the long run because it's a negative EV game.

Playing roulette or craps can be fun, no problem with that. When I do it, I know it's gambling and sometimes I like it.
Poker is a different process.

I've just won 2.5 BTC on SwC, I like this game ;-)
