Improper time increase and how to handle this game

[GreenAsJade]

Is there a Polite way to say that game is already decided?

It has come up before, and I think the concensus is that you pass when you think the game can be scored you politely keep playing up to that point if your opponent continues play after you pass, and clearly does not have a plan to improve their score, you report it There is no polite way to say “I think you should resign now”.
