Bonjour,
I want to add some endgame knowledge in my engine like KRP_kr but I face a problem that's fundamental.
The knowledge says : if white is to move and condition1, white draws => but this breaks the symmetry of evaluation and causes problem when reusing the eval after null move.

What can I do ?
Thanks

Should not cause a problem, as many of us do this very thing in many places. It is only asymmetric if you do a test for black but not for white. Then you invite issues...
