In this opening, the defining feature is often a central or queenside piece stepping away from a line, such as the c-pawn or a knight moving, so a hidden attacker suddenly becomes active against the king, queen, or an undefended piece. For an intermediate player, the key idea is that the opening structure creates long diagonals and open files where one move can reveal a direct threat.
