Is lichess broken or did I play perfectly? (100% accuracy)

I'm bad at chess, so I was very confused by this game analysis:



It says 0 inaccuracies, 0 mistakes, 0 blunders, 100% accuracy, and a centipawn loss of 1 (does it round up from zero?). I can understand having no blunders and no mistakes, but even then, normally I'd still have inaccuracies.

Is this like the chess equivalent of hitting a hole in one? Or was the analysis faulty / is this a bug?

Pretty sure you played optimal and near perfect so it is not a bug or faulty anaylasis

How common is that for a given lichess rating? I've never had it happened before as far as I'm aware and I've played 500-1000 games. Like, at the 2400 level do you play a perfect game every few games?

The game was over at move 3 (+12). Stockfish stops looking for inaccuracies, mistakes, blunders when the eval is +6 or something and stays that way the rest of the game.

Aww man, that makes more sense. Thanks for explaining.

What happens if the player having a win position blunders and the position becames equal?
That is my curiosity only, because I almost never use Stockfish in analysis of my games.

Reddit is right.

I'm not sure. My comment in #4 is based on my and others' observations, but I don't know the details.

Edit: My guess is that StockFish would get back to work.

Even leaving aside the specific issue in this game, it is possible to get 100% in short/mid-length games with obvious moves, especially when your opponent plays poorly. I've done it a couple of times on my old account and I'm rarely more than 1650.

I've seen posts where even lower rated players get 100% despite playing moves that look terrible to human eyes. Sometimes those foolish looking moves don't give up very much with computer defense. So in practice there is a bit of a random element to it.
