Junk [LEAK] Casino Kit: Roulette

I wanted some variety and decided to try online poker; at first, I lost money, then realized that I needed a strategy. I tried the Texas Hold'em strategy. The process works but requires a lot of practice; a successful poker game is, first and foremost, the ability to soberly make a competent mathematical calculation. Many novice poker players believe that you should never call a raise if your stack is less than a certain number of blinds. This opinion is likely based on a study of old poker literature. Obviously, you shouldn't establish your strategy on advice that is no longer relevant. Do you agree with this? I see similar situations and mishaps here all the time.
