  • The Weak-Square Complex

A "Weak Square" is a square that an opponent can easily attack, because it's either not defended or under-defended. A Hole is an example of a Weak Square, as it's undefended by Pawns, making it easier for an enemy Piece to safely land upon it.

These Weak Squares are often on the 3rd and 4th Ranks of either army's territory, as highlighted in Diagram 1, below ...

Diagram 1: Black has a Holes at d5,
(Black's 4th Rank)
Black's Bishop is on the wrong color to defend the d5-square and there are no other Black Pawns capable of doing the job, either ... White, on the other hand, just has to play Nd5 to be in possession of a Strong Outpost Station.

H&M-S define the Weak-square Complex as being a "whole series of squares of one color", which "may become Holes through the disappearance of the Bishop tied to squares of that color".

This is probably a more advanced concept to get your head around, but once you do, it will change the way you look at the game.

In its simplest form, concentrating mostly on the third and fourth ranks, in either territory, count up how many pawns are on dark squares for each side, and how many are on light squares. For instance, if you have 5 dark and 3 light (as Black does, in Diagram 2, below), that means that since the pawns can only attack on diagonals, they attack mainly on dark squares, so you are weaker on the light squares.

Diagram 2: Black has a light-square Weakness,
with 5 Pawns on dark-squares; only 3 on light.
Once you've got your head wrapped around that concept, the more advanced concept is to now consider how many pieces attack dark squares and how many attack light squares. If your opponent overall is weak on light squares, make him weaker by placing your pawns and pieces so that they limit your opponent even further.

Basically, you're separating out whether each pawn or piece attacks a light square or a dark square. Simple. Now increase your advantage, as you would on space or material. That`s it in a nutshell.

One more thing ... If you spot a Weak-square Complex in the enemy's position, and you have the chance for an Outpost Station (as in Diagram 3, below), a Bishop is often superior, as the Piece to placed onto the Outpost Station, than a Knight (which, at most other times, is the piece typically sent to an Outpost).
