This is actually a problem I&#x27;ve given a decent amount of though on (although not necessarily reaching a good conclusion), but I think these problems are actually related and not impossible for this simple case.  It comes to an issue of what parts of the analysis and at what depth did a best move come to vision?  Was it bad when it was sorted for 8 ply but good at 16?  Maybe that won&#x27;t &quot;tell&quot; a person why a move was good, but it gives a lot of tools to help try to understand them (which can be exceedingly difficult right now if a line is not part of the principal variation, but ultimately affects the evaluation by an existing &quot;refutation&quot;.  But I think the other &quot;difficulty&quot; is that 1800 players play badly in lots of different ways, 2200s play badly in lots of different ways and even Grandmasters play badly in lots of different ways, but very strong chess engines play badly only in a few sometimes limited ways.
