Subject: 'Problem' mate in N EGT !

Go up one level in this thread



Some work was done way back for Adv_Comp_Chess_6 on max(DTM) 'problem' mates
where White has a unique move to win DTM-optimally at each step.

There must have been an EGT but I guess it was not preserved.

This would be worth running again:  the modification to the retro-algorithm (or
to an existing DTM EGT) is that a 'win' is only regarded as a win if it has a
unique DTM-optimal move to win.

'Unique' needs a little care:  a positions symmetric about a1-h8 or h1-a8 cold
have two physical DTM-optimal winning moves which are functionally equivalent.
