Kb1, Na2-c1-e2-g1-h3-f2-d1-b2-a4-b6-d5-c7-b5-a3-c2-e1-g2, Kh3, Nh4 gxh4 Kxh4 Kf6 g5+

With a king move possibly inserted to force black to give up the b6 square (and protect the knight when it eventually passes through a3). If black covers c7 after Nd5, the knight grabs the h-pawn instead.

You can work the knight to a4, but black will just shuffle the king c6 -> d6 and I don't think you can shoot past either. Capturing black's c pawn will cost the knight and so material is equal and the king still can't get through.

Is this a famous study? I don't have it in my database.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

This is a new study but I don't know who is its author. I have just seen on Facebook.

Hi Arpad,


It looks like 1.Kd2! is the first move here

After 1.Kd2 I am surprised that stockfish find the solution.

With a king move possibly inserted to force black to give up the b6 square (and protect the knight when it eventually passes through a3). If black covers c7 after Nd5, the knight grabs the h-pawn instead.
Yup! Once the night hits h4 (with king on h3 so it can't be taken), and then f5, the a6 pawn dies. Getting it there is the trick! :)

I can add that I was surprised to see it because I expected stockfish not to see it because of null move pruning and I know that stockfish cannot solve some very simple problems that all engines can solve because of null move pruning.

For example the following problem when stockfish suggests Ka2 and may be the only top engine in the world that cannot see that Kc1 is winning in a reasonable time.

You are right that every king move is winning in both diagrams but the problem with my diagram is that stockfish see evaluation of 0.00 and does not see the win that I believe to be only by repetition if you do not play Kc1
