Sometimes it is possible to guess the why.

I do not see only move but also evaluation and main line.
If a program cannot see a simple tactics it is possible to guess the why.

For example if you see that a program evaluate position as a mate against itself
when there is a simple stalemate combination you can guess that the program have
a problem in seeing some stalemates.

If a program show after a move Rc2-c3 a main line of Qd3-b1 Rc3-c2 with
evaluation of 0.00 you can guess that the program evaluates repetition too early
and does not understand that Qb1-d3 is illegal after Rc3-c2
