really? why you are so sure about this? do you get much of winning with your play? because i only believe that win in the gambling is depending in our luck, beside that we can only loss. no matter how good your strategy, your calculation but as long as you don't have a luck, then its impossible you can get win. if your calculation work, then your luck should be work too.
I think strategy, skill, and luck is all needed. If you don't have skill and strategy then luck will be definitely on your side. But if you don't have a skill and strategy to play the game then luck is your only chance to win. You can't just depend on luck because it will not generate you some good profits.
