How deep do you analyse

Looking at the "difficult" questions in Month 2. Just wondering how deep each of us analyses. I confess I don't yet have the " board visualisation"to evaluate a 8 move deep "combination" ending with no material difference or attack, but simply a probable won endgame.

Those that end material up or with an attack I can do but the others. Even seeing the final position or moving the pieces I struggle. How did others deal with this? Reading the others on the forum seems to suggest we were more into the King in centre or board visualisation than the exrecises in Month 2. How do others use these exercises to learn or do we use them simply as a measuring stick for how much we learned?

I'm just about done with the King Safety theory/annotated games, and am about to start the problem sets. Most important for me is whether I got the first move right (after all in a game it's the move played, not the analysis that went behind it, that ultimately decides the quality, and often I will see problems with analysis once my opponent responds).

I'll be able to answer more, though, once I start the exercises.
