Even without playing, any tournament participant can accurately say which hero and with which army Uran was freeing from prison. So, there's no secret here. Many people watch the maps not only during the game but also before the game, and some even try to think of a plan of action in advance.
Pit, you shouldn't "explain" everything to everyone without understanding the essence of the question. The point is that Uran wrote that he saw the hero was good later, i.e., obviously, right during the game. And the fact that fixers watch all the maps before the start of the match seems obvious.
Question from Ewgeniy: Is it really possible to view the map being played in the editor directly during the game?
