A computer can give variations and scores, as that is what alpha/beta is
designed to produce.  It can't really give "reasons" for why a move is good or
bad, because alpha/beta isn't designed to produce that kind of information.  It
can show the best move, it can't tell you why it is best.

Perhaps one day this will be doable, when a second program passes over the game,
the PV/score information, and does some sort of pattern analysis to try to
explain why this move or score is best.  Today it comes out as looking like
something a monkey and a typewriter might produce given enough time.
