I am not searching for a shortcut, but trying to figure out where I am lagging.
But I am afraid I may end up wasting half of my life in finding out a perfect strategy.
Probably no or random strategy is the right approach ? or just searching for a new strategy is the real fun in gambling ?
No strategy suited for gambling. The best strategy is being an organizer of a gambling site because it will assure you that you will get or make a high profit.

No more shortcuts to be a winner, it needs a hard work and stay focus. It's not recommendable to do a gambling to let you win.
sorry but in fact that is a dumb strategy. because just being an organizer! can not make you profit. you may see all of them out there with so many players and so much money going in and out so say to yourself it is a profitable job by nature. but in fact these guys have had lots of experience and tried really hard to get there. it didn't happen just like that.
