Where the games come from, who gives the verdicts – and what is made of them.
Two collections of known origin. Many games stand there more than once – once with each player. The endgame finder reads each only once (same year, same moves) and left out 409,762 duplicates.
Main source
A large, freely licensed PGN collection with the games of many players – the ground of almost every endgame of this site, from the classics of the 19th century to the world champions.
Besides: recent tournament games
Tournament games of recent years complete the collection – the endgames of today's top players too. I show them on this website with the permission of TWIC.
With few men left, chess is solved: the Syzygy tablebase knows the exact result and the best move of every position with at most five men. The verdicts of the trainer and of “Where did it turn?” – won, drawn, lost –, every only move and every solution there come from it, not from an estimate.
Where more men stand, Stockfish computes – to a limited depth and as an evaluation, not a verdict. Such numbers are marked as Stockfish values on the pages.
A game counts as an endgame as soon as besides kings and pawns at most 4 pieces are on the board – or the queens are off and each side has at most 8 points of pieces (rook and minor piece). At move 10 at the earliest, and the condition has to hold for 4 half-moves in a row.
