Strategy does work very well in skill based gambling, the challenge is that most of you do not have strategy and felt that what you have is a strategy when it is not. Strategy should be comprehensive enough to compensate for down times, which are times of losses but unfortunately,  most gamblers do not want to see losses and when it happens, they abandon whatever method or strategy they are using because loses were never part of their gambling strategy.  Strategy truly work in gambling , it's just for the gambler gambler setup one and follow it religiously.
