Thank you, after joining your club I was thinking about weak squares and strong squares, and almost asked you if you'd do a video on this topic some day? I did a search on the subject in the video section and didn't see to much. This is a difficult area for me to understand. Thanks for posting this. I'm going to check it out.

I'm subscribed with your you tube channel, and will follow your lessons about weak squares. I'll study this for the time being. Thanks friend.
Today I would like to present you guys about the weak squares and strong squares.So I hope you all will like it too.I will also post a video on it on youtube with annotated games tomorrow .I will make playlist of five games which will cover all the rules which arise with this concepts.
Weak squares-
Weak squares are those which can not be defended by any pawn.This is the basic defination of a weak square .
for ex-
In the above position b5 square is a weak square
How to exploit these squares-
1. Your main task in these sort of situation is to turn the opponent's weak square into your's own strong point by seizing it with one of your pieces.The most important squares are those located on that side of the board where the main action is taking place .Furthermore special attention should always be paid to weak squares in the centre of the board and near the king.Knights and bishops are the best pieces for seizing these squares,though other pieces can fulfil this task to.
2.The capture of a weak square has to be carefully prepared.Before seizing it,you should always try to control it with more than a piece.If you can not avoid changing on your pieces on that square ,see to it that after this exchange it can be substituted by another piece or pawn .
3.Weak square are often appears in front of backward isolated pawns.In that case the capture of this point also helps in the struggle against such pawns,as the occupying piece is at the same time blockading the pawn .
