Weak boxes

Well first the names of the boxes

In this position, black has a major weakness in the f6 square, which cannot be protected by a pawn and where white pieces can be set, for example the bishop. The fact that this box is in black castling gives it paramount importance. The h6 box is also weak, according to our reasoning, but at the moment, there are no white pieces to attack it and the bishop in f8 protects it properly. However, if this bishop is changed, the h6 box (also located in the black castling) will have great importance, as shown by the development of the game

All black cells in the black field are weak, particularly e5, f6, h6. It is interesting to see the development of this game and to study how this situation came about after the change of the black-box bishops.
