yeah
My opponent got 100% accuracy, but I still won

If someone only plays book moves, then the accuracy is 100%. If they start playing Best Moves, the accuracy will drop below 100% even though that's the best option (aside from Brilliant).

yeah, i once saw two people play 18 book moves of the ruy lopez marshell variation and they both got 100%

I made 100% accuracy with the Traxler counter attack:

Literally the worst move is an exellent move, everything else is great, brilliant or best move

my last game i got 100 percent. We played up to 17 moves and he resigned lol. The worse they play the easier it is to make good moves.
you didn't win then. It would be recorded as a loss for you though your rating will be unaffected by it
