Weak squares and a pretty mate.

After I wrote my first blog entry about "Power of pinning" at http://blog.chess.com/minashokry/power-of-pinning, again, I speak about another common mistake that even some experienced players may make which is weak squares.

A weak square is defined as a square you can not attack (or defend) by pawns.

You have to think twice before advancing pawns and see if the move will make a weak square. You have to calculate the risk of making a weak square in your defences because a weak square for you will be a strong square for the opponent.

On the other side, if your opponent made a weak square in his/her defences, then, it is your lucky day and you have to make him/her learn the lesson not to do this again.

Look to this game that I played recently (actually it isn't finished yet officially, but my opponent now in a situation he can't avoid mate! so, I consider the game finished).
