I somewhat understand the concept of attacking the king and pieces, but "attacking" squares is a bit of a vague concept for me.
What are weak and strong squares? When do you use them? How do you create them?
... that all of the squares behind the pawns are weak by default.
Counter-intuitively: Strong squares are squares which are defended by a pawns.
These square are very powerful places for opponents Knights or Bishops. No pawn can attack to these pieces. In below position, square
d6 is a weak square for black and also strong square for its opponent.

e6 are some weak squares for black and also
d4 for white (however it's too late for black to put his Knight there)

They're useful to place a Knight or Bishop in near the heart of opponents position. Usually making a weak square in the opponents land needs long term strategy. You have to force the opponent to pass its pawns...Tweet
