Subject: Partial or user-defined EGTBs

Author: James Constance

On analysing an endgame with more than 6 pieces, many variations lead to
identical  positions which I know to be won or drawn.  I think it would be
useful if I could somehow tell the engine to evaluate these positions as won or
drawn. Rather than needing a huge EGTB file, I would only need to set the
evaluation for a handful of positions - the engine might then be able to see if
the won positions can be forced, and the drawn positions avoided.  I suppose
that, given the right software, one could also define more than one position at
once, e.g. if the pawns are here, the rook can be anywhere on the board etc.

Is it possible to create partial EGTBs, or does an EGTB need to be complete for
all positions with those pieces?

Any feedback for being able to manually set an evaluation for given positions?

Anythig currently out there along these lines? (apart from Shredderchess's
Freezer)
