It makes me wonder “what’s the difference between a “game” and a “puzzle”?”
For me, I would have said:
a puzzle is a position without context, that you need to “solve” by finding the best next move.
a game is a position with context, where you bring your knowledge of how it got there…
Of course, things like “many-vs-one” competitions show this isn’t really how the pros always do it: you see them arrive at the position, play the next move, and move on. Maybe the “context” is in fact just distraction?
Although stone.defender’s experience tells us it’s useful distraction
(with Live time settings)
If your position awareness is good enough, you are inevitably able to know which stone is the last move. If you don’t know which stone is the last move, therefore your board awareness is not good enough.
I able to tell which stone is the last in most cases. So its not really puzzle mode.
If you have people who play when you are away you are quite unlucky. Besides in that case I usually find where they played. If in a friendly game (no clock) i feel a bit lost, i prefer simply asking “did you play?” before anything more, and that’s usually enough to find the move.
