The Process of Decision Making in Chess Volume 2: Practice positions and solutions. Position 11.6

Solve the challenge below:

Diagram 11.6- white found the d5 weakness in black’s camp, but alas, it cannot be used! It is merely an “irrelevant weak square.”
Challenge: if the d5 weakness can’t be used by white, should black try to eliminate it anyway?

of course no. Blacks is not prepare to break in the center they must to abide their central pawns and attack on the king side 

Black shouldn't remove this weakness right away, but in the endgame it might become a problem if black doesn't make an attack on the kingside quick enough.

Also, his control should be better for side attacks more than the center.

Though the d5 square is weak, the d6 pawn is the real crutch, as it embarrasses the dark squared bishop. I think that control of the d5 square is a goal for black so that the d pawn can be pushed, traded, and off the board. Without this pawn on the board, Black's position will be much easier to play

Hi! my frends

White could occupy d5 square with his knight after six moves (Bd3 developing his bishop, Re2 freeing the e1 square, Ne1, Nc2, Ne3, Nd5), so Black has time to prepare himself
