Explain the Basic Rules of Chess to a Complete Beginner

Chess looks intimidating before you even learn how the pieces move, and most explanations assume you already know more than you do. This starts with the objective in one sentence, explains each piece from simplest to most complex, walks through check and checkmate with a real example, and flags the one mistake almost every beginner makes early on.
