There's just an empty space!", the bishop in the Kozłowski study might say this. | Photos: Pixabay

4/24/2021 – How do you know that there is exactly one way to solve an endgame study? Tablebases are a proof, but unlike many other genres, there is no way to heuristically solve a study to find a complete proof of it being correct. That is where cook hunters come in.

It became pointless to issue a challenge and provide prizes. So we have taken to giving you problems which cannot be solved by computers. Here are some samples from a collection by Burt Hochberg.
