In my article on the expected winning study of the 11th FIDE World Cup on Composition 2023, I recently claimed that Syzygy endgame tablebases (EGTBs) can suggest suitable starting positions for endgame studies and all it needs is a bit of programming. In the case of this single study, however, it's a lot simpler.

 

The site https://syzygy-tables.info offers online access to the EGTBs for individual positions.

 

Please open this page and setup any position with KRN vs KPPP on the board.

(Alternatively you can copy this FEN 4k3/3ppp2/8/8/8/8/8/3NRK2 w - - 0 1 into the field under the board and press Set FEN).

 

Would you believe that you are now just two clicks away from downloading a PNG file containing most of the mainline of this study? That's the way it is!

 

The first step was to tell the site the correct EGTB. The right side of the page can be scrolled down.

Below the moves with the DTZ values, a download link already appears (see KRNvsKPP.pgn), but before you use it, scroll down to the Longest KRNvKPPP phases section. Press the last option KRN winning with DTZ 65, and then use the download link.

 

The board should show this position.

The downloaded file contains a move sequence representing the extremal DTZ sequence. Up to 28.. Kg3 it is identical to the main variation of the winning study.
