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).
As you see this situation was in move 16, After another 16 moves we were in the next situation and the hero knight at d6 made a solo show to give a really good mate.
Can you solve it and give mate in 5?
