I guess that Junior has evaluation function only for moves like other programs
and does not caculate goals to achieve like humans.

I believe that thinking also in terms of goals is important for chess because
programs sometimes cannot see tactics because they do not think where they want
there pieces to be.

Here is an example:

[D]r1r5/BRp3pk/Q1P4p/3p1p2/3Pp2q/2P1Pb2/P4PP1/1R4K1 w - - 0 1

How much time do program needs to see that white is losing.

white lost in the game after 27.Qf1 Re8 28.Bb8 Raxb8 29.Rxb8 Re6 30.Rf8 Rg6
31.Rxf5 Rxg2+.

There is nothing better than Rxf5 because the saving material move Rbb8 is
losing against the original plan Rg5 with the idea Rh5 and Qh1#

How many programs know that the rook wants to be at h5?

How many programs know that it is important to extend the lines when the rook
does the quiet moves Re8,Re6,Rg6,Rg5,Rh5 and knows also that Raxb8 is an
important move to extend because the white bishop is a defending piece?

I believe that no program of today but I may be wrong about it.
