Am I dreaming? Today otb team game: both player ACPL 6 and 0/0/0

Thanx #2.

Don't worry, there are more parameters than ACPL and mistakes to catch out cheaters. But speaking only for me I doubt that I could play a 40-move blitz game without any errors.

Yes , but it also depends on the Type of Game you and your opponent play .

Sure. In tactically demanding positions the engines go mad when assessing human moves.
