If it is not impoprtant if you play Rab1 or b4 then it means that this position
is not a good test position.
I understood from the test that the claim was that b4 is the only best move
and if it is not then it is bad to use the position as a test position for
computers.
I did not say that seeing the plan of white cannot be productive for humans.
