Hrqls: grenv said "If you analyze immediately after a move it may give you insight into the position that you wouldn't otherwise have".

That wouldn't apply to a cube decision unless recubing wa sin the air but woudl to chequer play.

With chequer play it depends on the move and the stage in the game. If it was about whether it was wise to risk putting a blot somewhere and that blot's been hit taking the game into a new phase then there is no danger of gaining inappropriate knowledge about the current position - too much has changed.

As an example of a case where I wouldn't give advice, say you are trailing badly and have hit a last-minute blot and are trying to contain it. I wouldn't discuss how you'd lay your backrunner net down or build your forward blockade on a particular move because the advice would be strategic and cover that whole phase. On the other hand I was happy to discuss Czuch's game just now because there was nothing he could gain from anything I said.
