Obvious cheater
Sort:
Played with an obvious cheater just now.

How can you have 46.9 accuracy, 3 blunders, 4 miss, and 1 mistake on your last game then skyrocket to 90.1 with 0 blunders, miss, and mistake and all best move on the next game.
And of course, the most obvious giveaway is taking 20-30 seconds per move even though the move is pretty much obvious (probably too keep his engine as accurate as possible). Another giveaway was the very obvious mate in one still took him 10 seconds.
