Yes. Just resign on the first move and boom. 

It's hard to say what's the reason, probably engine/depth used, but there are games where both opponents have 100 accuracy

For example:

opponent resigns, quaking in fear at the undeniable confidence exuded by your avatar

Idk is chess solved?

In this game Black got 100% accuracy.

Only in some rare cases. It'll occur mostly on small games

For me it said you have 100% accuracy

I got a very high score before

You can easily get 100 accuracy if it's an attack with a lots of book moves and good moves. I got 100 accuracy by playing fried liver attack.

same

Yes it is. But then you also have to play engine style opening moves 

Wich is why I hardly ever get the chance.. I always have something it labels inacurracy
