I'd almost like to try it. I think we could use the actual video footage. Take a screenshot when neither player is in the frame, and edit out the scoreboard, etc. Crop the picture to only show the table up to the rails, so as not to give away any background that might clue the player where it was.
The way it was done with Magnus, he remembered games that he didn't even play after just a few moves. IDK if that was real or BS. If its real, certainly Shane would be able to do the same with a full table picture after the break.
