Let me share my answer to one of my student's questions. It is about the elementary and typical kind of fortrees in pawn endgames.

Question:
Could I ask you about this pawn ending? This was agreed as a draw.
In this position below if both sides triangulate with their Kings will it still be a draw?
Many thanks.
Answer:
Yes, here it is an easy draw, and no even need for a real triangulation, since for White it is sufficient to keep the squares of possible penetration b3 and a3 with moving the K on a2 ,a3 and b2, and for Black king it's sufficuient to move with King back and forward on b5 and a5, and no way to break through to the key winning squares, and all other squares of possible entrance are safely locked by all the blocakded pawns and squares they control - a kind of fortress. Most likely Black will go Ka4 now, trying to intrude, but White has Kb2, covering both b3 and a3 squares, and what is the most important that White will be able to maintain his King on those key squares further and there is no way Black can do anything about it.
