In the wikibook Elements of chess strategy you can find an explanation of the most important ideas of chess strategy:
- The center
- The positions of the kings
- Weak and strong squares
- Pawn structure
- Queenside pawn majority
- Open lines
- Minor pieces
We have seen most of these positional ideas before on Chess Teaching, but the mentioned Wikibook describes them in a rather different way. This enables you to see the ideas from different perspectives.
The information about the weak squares is a nice follow-up on our lesson about the weak pawn.
Weak squares are squares which cannot be defended by a pawn. These weak squares are thus open to occupation by an enemy piece. For White, weak squares can usually be found along the 4th and 3rd ranks, while Black’s weak squares are often on the 5th and 6th ranks. One of the qualities of a weak square is that it increase the value of the piece that occupies it. This is especially true for knights, which need advanced support points to be effective.
In the next lesson we will pay atention to the game Edgard Colle – John O’Hanlon, Nice 1930, which is one of the most used examples of the classical bishop sacrifice.
