Looking for more explanation on Sharpness

From the docs: "It also calculates the sharpness of a move, as defined in Evaluating sharpness with Leela’s WDL"

The leela WDL doc is a little over my head. Looking for how a basic human would use this stat.

My best guess, and my hope, is that it tells you how easy it is to screw something up if you make a particular move. The lower the sharpness, the more idiot-proof the line you're entering is.

It seems to just correspond to percentage of draws - the higher the sharpness, the less drawish the line. That could entirely be coincidence though.

These are just wild guesses though. Would love some enlightenment and advice on how to use sharpness when deciding which move is best for an average human. (Whereas stockfish evaluations like to send you down tricky lines that require you to play perfectly or you lose)

Sharpness is a measure of how much danger is around. Think of it as the soundtrack of the scene. One wrong move and they will Git you!

I have to say that I implemented it on a whim. I've never found a real use for it :D Let me know if you do.

sharpness seems to be in the eyes of the beholder of the word. Or I think there are at least 2 notions roaming around in the community of web recorded discussions.

I would like to see a discussion somewhere, that does not start with truth from above, and allows the possibility that more than one meaning has been persisting for a while. That would not be a new thing, that words would keep having some overlapping meaning sufficient for different specific board object pointees surviving for some generations. Let's sharpen our definition by accepting the fluid or existing fog, and fallibility of language or few words to capture well objective realities of the chess board (or many of them in legal transitions sequences).

I think op is right to be prudent and handle with the care of guess status, this kind of language. I would not jump on any one computed definition and seal that forever in any one's mind. (bad tradition of that, leads to maybe this kind of mess... hypothesis is also a word, that we might cajole in chess theory, for its own health).
