Description

The other day someone was sharing games where AI level 8 randomly shuffled its pieces and even missed a win due to the 50-move rule. Sorry I don't have the game URLs.

Stockfish calculates more accurately with 3-4-5 WDL & DTZ models from https://syzygy-tables.info which is why the official-stockfish team uses those in its selfplay (parameter tuning and patch testing) tests. At the end of a PV, there may be 5 or fewer pieces, so it helps to be able to look up which endgames are won, drawn, or lost.

Pieces | Tables | WDL | DTZ | Total
-- | -- | -- | -- | --
3-5 | 145 | 378.1 MiB | 560.9 MiB | 939.0 MiB

Research direction

The issue names no repository files, tests, or entry points. Start by reviewing the 3–5-piece WDL and DTZ requirements on syzygy-tables.info and the fishnet repository context; done means those tables are deployed and available for the intended Stockfish analysis or self-play work.
