I thought the blog was gonna talk about what Ding Liren could have done to prevent what happened to him
well if only testing some aspect, could lose the game even if winning. after having been satisfied with some intermediate outcome. maybe. this would have made the opening explorer report an off beaten line as losing ultimately..
would that not work for the preparation layer of chess.
well that might not work if going from tournament novelty to lichess database. it would be found. and scrutinized, and should be even if not from same player and not about preparation secret keeping.
