I think that not considering all the possible moves in the first ply is a
typical human mistake.

There are cases when humans did not play a good move only because they did not
think about them.

I believe that humans can get better in chess if they use a small part of their
time for generating the legal moves of them and their opponents(they cannot do
it in blitz but they can do it at tournament time control).

The problem of computers is not the fact that they consider the legal moves for
the first ply but the fact that they do not know to prune illogical lines and
the fact that they do not know to think about other things like planning where
to put their pieces and generating moves later for this target.
