The benefits of blind stealing begin with the addition of chips to your stack.
That includes raising with medium-to-weak starting hands you don't necessarily want to play postflop, although any time you open with a preflop raise you should be thinking about how you want to continue should you be called or reraised. I'm referring to those instances when a player open-raises before the flop with a primary goal of earning folds and winning the blinds (and antes, if in play) uncontested. Blind stealing in poker tournaments can produce a number of positive outcomes.
