I don't see any value in them myself, but i too have a "feeling" sometimes of winning big, and while i don't believe it would mean anything, that doesn't really differ it from any other belief. I still enjoy getting that feeling and acting on it by gambling.
whatever strategy the gambler does, there is a possibility of increasing comfort and confidence in the game. but if it creates a feeling of winning big, I see this as something quite dangerous for gamblers and should be avoided.
getting pleasure and confidence from skills plus the feeling of winning big, can cause excessive betting responses. the best strategy in gambling is to control our gambling finances. don't bet beyond your ability.
