Yet earlier in this thread, you were incredulous about even the possibility that a chess game state could be entered into software or communicated during play. Which is clearly a ludicrously blind statement. So pardon us if it's hard to be particularly impressed by, well, whatever you are impressed or not impressed by. Because you don't seem to have much grasp on the basics involved, here.
This statement came from an experiment I conducted. I just tried playing lichess 3+2 game while running a nearby chess.com/analysis on a second display. ...
... and I was barely keeping up with all the clicks, and in the endgame was unable to keep up. So no, efficient cheating in fast games requires at least a special training, and better some automated software to keep up with the moves and to communicate best moves back to player.
I don't claim to have great cheating skills, yet, I'm pretty sure that doing such operations while streaming is very difficult and would be easily visible to the audience. They likely require an assistant or some specialized software.
