Key indicators for deeper analysis I have trouble with managing my time in my games. I cannot determine if I need a deep analysis  or I am in a position where any good move would do.

So, what are good indicators to determine if a position needs a more deep analysis or to just play any good move?
If I see a position which can have multiple continuations, I will analyse each one and think everything through. Till then, beginning and end game should be pretty much the ones to take the least amount of time, because they can be learned. 

Basically focussing on your question fully, if the positions seems complicated - analyse deeper and don't think about time. But once you chose that tactic, work your way through it and don't hesitate. 

I might've misunderstood what exactly your question was, but I hope I didn't...
