It is a problem of the following:

1.  not recognizing king safety and the danger of a pawn storm until it is
too late;

2.  not knowing how to attack the opponent, because when you castle to opposite
sides, it becomes a race to see who draws the first blood.  If you don't know
how to break the position open (and I have not seen any programs do this very
well) then while the program fiddles, Rome burns.

3.  castling opposite is a direct challenge.  Quite often the human will have
his pieces positioned to support his attack, while the program's pieces are
positions improperly to attack or defend.  The time lost repositioning them
leads to trouble.
