Knight versus Bishop ending

Today we give a sample ending of Knight versus Bishop based on the same source, where the King has no more legal move and is thus stalemated.

The Knight versus Bishop endgame posted yesterday was from the excellent book entitled "Detailed & Categorized Practical Endgames" by Lee Chee Hoi & Pan Xianda, published by Xin Sheng Publishers, Macao, around the mid-late period of last century.

Lee Chee Hoi & Pan Xianda have sum up the important points in Knight versus Bishop endings, pointing out that :

1) Bishop and King should not be on the same side, and care should be taken of the possibility of the Knight's move to the Palace corner when the Bishop is positioned on the edge.

2) the King should not go to the top level of the Palace at any time.


It is reasonable to ask :

But what will happen if the King is at the Palace's top?

Let us look at the case of the example "King at the Palace Top"
