Number of moves before automatic draw
Instead of having a fixed number of moves without capture or pawn moves before automatic draw why not base it around the number of pieces/pawns left (not counting the king)

Only kings left: 0 (instant automatic draw)
No piece but at least one pawn: 30
One piece: 50
Two pieces: 100
Three pieces: 150
Four pieces: 200
At least five pieces: 250

Note that https://fairyground.vercel.app/advanced.html will not retroactively award draw if you change the nmoverule if you have later made a capture. You can simply copy over the move list and change the settings when a capture is made (not fully ideal but should work fine).

Rules
You win by checkmating your opponents king or by being stalemated.

The knight, bishop, rook, pawn and queen are move like pieces in standard chess.

The king cannot castle but otherwise moves like the king in standard chess.

A pawn has to be promoted to centaur, archbishop, queen or chancellor when it reaches a rank numbered 2 or 9.

The centaur
combines the power of the king and knight but cannot get checked.

The chancellor
combines the power of knight and rook. Cannot jump over pieces when moving like a rook obviously.

The archbishop
Combines the power of the knight with the power of the bishop. Cannot jump over pieces when moving like a bishop obviously.
