Answers.Body: <p><a href="http://kirill-kryukov.com/chess/longest-checkmates/longest-checkmates.shtml" rel="nofollow noreferrer">Kirill Kryukov's website</a> is perhaps the best starting point. Here, all of the longest endgames for material configurations are given if for positions with 6 pieces or less and without a 5+1 piece count. For the moves, you could make a script to run each position through [Shredder](<a href="https://www.shredderchess.com/online/endgame-database.html%7D" rel="nofollow noreferrer">https://www.shredderchess.com/online/endgame-database.html}</a> and record the best move sequence.</p>
  <p>For reference, here is the entire list copied down and sorted by length, which the site <a href="http://kirill-kryukov.com/chess/longest-checkmates/longest-checkmates-sorted-by-length.shtml" rel="nofollow noreferrer">has as an option.</a></p>

Answers.Text: The [endgames.pgn file](https://syzygy-tables.info/endgames.pgn) mentioned in my question is a strictly better source when it comes to finding a longest endgame. I am interested in all (!) longest endgames rather than just one.

Answers.Text: Take KRNvKNN for example. You provided exactly one endgame (6k1/5n2/8/8/8/5n2/1RK5/1N6 w - - 0 1), which is indeed a longest endgame for the given piece configuration. But your list has to be incomplete since we can mirror this position and get another longest endgame, for example (1k6/2n5/8/8/8/2n5/5KR1/6N1 w - - 0 1). For any given piece configuration I'd like to know all longest endgames.

Comments.Text: I'm not sure there is an easy way to do this. You could of course generate your own tablebases and keep track of this, but I think at least the syzygy files themselves don't give you easy access to that information.

Title: Finding every longest endgame for each material configuration
ThreadText: # Finding every longest endgame for each material configuration
  
  (Asked by: username_0 on 2021-03-06)
  
  I can find statistics on the number of moves until checkmate in the [Syzygy endgame table](https://syzygy-tables.info/endgames) for each material configuration. Let's say I am interested in ["KQQvK" endgames](https://syzygy-tables.info/?fen=8/8/8/1k6/8/3K4/3Q4/3Q4_b_-_-_0_1). [The statistics](https://syzygy-tables.info/stats/KQQvK.json) show that there are exactly 40 positions in which white can force mate in no less then 6 half-moves. Here is one such example given by their [endgames.pgn file.](https://syzygy-tables.info/endgames.pgn)
  
  ```
  [FEN "8/8/8/1k6/8/3K4/3Q4/3Q4 b - - 0 1"]
  
  ```
  
  Of course, I could mirror this position in every possible way, but this will not cover all 40 positions that require the maximum amount of moves. How is it possible to generate each position?

  [Kirill Kryukov's website](http://kirill-kryukov.com/chess/longest-checkmates/longest-checkmates.shtml) is perhaps the best starting point. Here, all of the longest endgames for material configurations are given if for positions with 6 pieces or less and without a 5+1 piece count. For the moves, you could make a script to run each position through [Shredder]([https://www.shredderchess.com/online/endgame-database.html}](https://www.shredderchess.com/online/endgame-database.html%7D) and record the best move sequence.
  
  For reference, here is the entire list copied down and sorted by length, which the site [has as an option.](http://kirill-kryukov.com/chess/longest-checkmates/longest-checkmates-sorted-by-length.shtml)

  > **Comments:**
  > **username_0**: The [endgames.pgn file](https://syzygy-tables.info/endgames.pgn) mentioned in my question is a strictly better source when it comes to finding a longest endgame. I am interested in all (!) longest endgames rather than just one.  
  > **username_2**: @username_0 What do you mean "one"? I have listed literally all of them for up to 6 pieces (minus 5 to 1).  
  > **username_0**: Take KRNvKNN for example. You provided exactly one endgame (6k1/5n2/8/8/8/5n2/1RK5/1N6 w - - 0 1), which is indeed a longest endgame for the given piece configuration. But your list has to be incomplete since we can mirror this position and get another longest endgame, for example (1k6/2n5/8/8/8/2n5/5KR1/6N1 w - - 0 1). For any given piece configuration I'd like to know all longest endgames.  
  > **username_2**: @username_0 That seems rather arbitrary, but alrighty. Good luck with your endeavor.
