A passed pawn forces your opponent to use their most powerful remaining pieces just to block its path, leaving the rest of the board vulnerable. 3. The Principle of Two Weaknesses
If your opponent is defending perfectly against one threat, you must create a second, distant threat.
Zugzwang occurs when every possible move your opponent can make worsens their position. By "wasting" a move or making a slight adjustment, you force them to step away from a key square or weaken their defense.
