Why You Should Be A Control Freak

Seems like the picture for Qxd7 is missing? (Or is it meant to be a generic Knight on white background?)

Excellent article otherwise.
engine does not tell us the room that our position has. I jumped to the recap. And noticed that line.

multi PV might force engine to tell us more. About the profile of the PVs, is it flat or not.

In puzzles we are systematically trained in contexts where there is no flat profile. Even the solutions will stop abruptly, if encountering a flat profile zone after few moves from the initially non-flat puzzle challenge, post blunder position from game source.

So, good on you to make it clear. That there is something to learn about the soundness of a position beyond existence of one best move. We lack tools for that, automatic tools. I have no solution. but being aware is a first step, toward some study plan, on some long term project about improving or learning about chess.

I am not sure about the "control freak" angle if keeping the room open is doing that. (not open position, talking about proportions of good enough moves, and perhaps less room for opponent (is there a zero sum going on there?).

Great help to understand engine calculations vs. human thoughts!
