I think that ply depth is an excellent indicator of understanding of the
position unless the program has bugs.  That is to say, if one program finds a
best move at ply 10, so will the other most of the time.  Certainly, if we have
a complete search (no special pruning) and two programs complete the same ply,
they will have very similar answers most of the time (given that the eval is
half-decent or better).

If one program gets two piles deeper all the time, I think it will even beat a
program with a somewhat better eval.
