And also if it’s a sacrifice that only a person or low level player would fall for, it won’t count it because they see them but threat and will evade it but a human might not see it so they will count them taking the bait as a blunder or mistake
I also did a Legal’s Mate (if you don’t know what it is then look it up) and the player fell for it and I had mate in 2 but it counted his move as a blunder and not mine as a brilliant (technically he could’ve won a knight when I sacrificed but he saw that he could take the queen instead and fell for the checkmate.)(it also counted my move as a blunder because he could’ve taken my knight lol😂)
