You cannot win gambling when you don't have a self discipline, a self control. In one game you just have to be a formal Player to get the best move. If you have it all I'm sure people get luck every turns to wins.
Oh then to get good luck you have to be able to play like a formal player and have self-control? and then luck will come to you? I think it's funny and weird, luck can't be expected when it comes, and self-control will only help you to not become an addict and know when to stop, not determine a win
