The mentle part of chess

Today I will talk about the defence being not just defence but a offence as well.The chess board shows my type of defence that I think is the fort knox of chess.In this defence the opponent slowly goes nuts trying to take it down the defence.In this period the player will  give up a one pice at a time and then you will leave the fort and check mate the king.This is an old war trick armys would use, make the attacker  fire and  try to take down the fort  until their  out of ammo.Then take them out.All I have to say is a good defence is a good offence and when you get your opponent to think he cant brake you will brake him.This is a mentle part of chess people will see over time.
