The story

A knight endgame full of turns. After 65…♘a6 Stockfish sees White clearly winning, from 68…♘xc5 the tablebase confirms it, and with 70.c8=Q Keres gets a queen. But after 73.♔c6 – queen against knight and pawn – the tablebase shows: a draw. Still the game counts as a win for Keres; whether Landau resigned or lost on time, the game does not tell.

The moves from the start of the endgame

Values: Stockfish 19 at depth 24 with a time limit, for White in pawns; from five men or fewer the verdict of the Syzygy tablebase. A measurement that did not reach the depth does not count.
