An Outside Passed Pawn is a passed pawn that forms near one edge of the board and can draw the opponent's king after it.

Why is it Powerful?

• It draws the opponent's king away from the center.
• It can lead to a second pawn gain on the other flank.
• It dictates the tempo in pawn endgames.

Even if an outside passed pawn does not directly promote, it often wins the game through the distraction it creates.
