I would say that was a big big point. Surely one of the factors the game got changed. If possible, check that in video. Verma had to fight against himself psychologically . But it was too late to happen . And shi yuqi rightly attacked and took advantage as any player would do in the third game to win the match. However , no one can 100 percent say that point would have defined the winner. But yes a crucial point. I hope bwf reviews and fixes this such that in future , nothing like this happens.
