Excerpt:

<Most of this I learned from an interview that Jacques Davidson gave in 1962 to the Dutch newspaper 'Het Parool.' The title that journalist Willem Witkamp gave to his wonderful article was 'The Great Davidson.' This was somewhat ironic, because Davidson was a strong chessplayer, an international master, but he was not what most people would call a great chessplayer. But it was not completely ironic. Davidson was the first Dutchman who succeeded in being a professional chessplayer, and that in a time when only the very best of the world could live on chess.

Sometimes Davidson had to take little jobs on the side. For a while he was a traveling salesman for a publisher of encyclopedias. But to the end of his life, he was above all a professional chessplayer. And because of this, in a sense he was really a great man.

Around 1920 he was one of the strongest Dutch chessplayers, but not much notice was taken because Euwe was so much stronger. Davidson played in tournaments, the strongest being that in Semmering, 1926. But most of his income came from simultaneous displays, lectures, newspaper articles and the selling of chess books, often going from door to door. The income was small. In the interview mentioned he said: "Nevertheless I have raised four children decently. You shouldn?t do that. Raise children, yes. But not from chess.">

<this seems to be a 'try', because the author solution, as communicated by the Dutch chess collectors’ group “Motiefgroep Schaken” in a booklet on Chess related gravestones, is:

"1.Kc9 or 1.Kd9; the king goes to heaven, and his rival is mated"
