What is the difference between Kostya "analyzing" the situation and taking various screenshots? Do you see a fundamental difference? I don't.
I agree with Pavel. In official tournaments, I always paid attention to how the judges handled such cases.
And regarding
To "refresh his memory," it is usually considered good practice for a player who loads a game after a break to give his opponent time to look at the situation and only then pass the turn.
In general, I am against such things, but if a match drags on for a longer period than the amount of my RAM (about 3-4 days...):)), I think it is necessary to take a break and refresh my memory, because I have already lost a bunch of matches in which I simply lost track of the game after saving.
