This is the stats for KRBNvKQN... a bit weird to see mate this long but due to different metric I'm uncertain about its correctness.

[Dann Corbit]

That is really, really interesting.

[Nordlandia]

The longest 7-piece mate - 549 moves according Lomonosov Tablebases.

Longest win: 1098 plies.

[syzygy]

Max DTZ = 517 moves as calculated by Marc Bourzut, so 1034 plies seems correct.

[koedem]

I assume these are plies till conversion? (otherwise I don't understand how for the same player to move there can be even and odd plies)

Is the gap for white to move and win ending just behind 50 moves (rule jump from 65 to 101 plies) coincidence? Also, how does white have a win in 101 plies but after making a move black doesn't have a loss in 100 plies? Does that mean the White move was a capture and the loss in 100 plies is a 6 men position?

The 50 moves rule should be set off for engine matches and tournaments.
At least for Stockfish vs ...

They are plies until a zeroing move (or mate). Zeroing moves are moves that reset the 50-move counter, so captures and pawn moves.

If a position is a win outside the 50-move rule (a "cursed win"), then its value is either the number of plies until a winning zeroing move (or losing by the other side) or 100 plus the number of plies until a zeroing move into another cursed win, whichever is smaller.
