The idea of the Fortress - achieving the draw from an inferior position.

Sometimes we can create a "fence" that prevents our opponent's King from crossing over onto our side of the board. This can be important if we are a pawn down.

If we look at the initial position above we could imagine a pawn on the e3 square for the second player - the black team. As long as the White King stays near that pawn it will never sneak on by and promote. So all the White King would have to do is just play moves like Kd1 or Ke1 and then to step back up in front of pawn. If the pawn moves then the White King will be able to capture - all while having kept the Black King on "his" side of the board. A nice trick to know for King and pawn endgames.

Obviously this could be from a game where Black was winning - but wasn't careful about how and into what kind of endgame that they went into. His opponent - the player playing the White pieces knew what they had to do to save the game - Build a fortress! Now it is a draw!

A Study that requires the use of "fantasy" - that is imagination!
