4) Something like
setboard 8/2B2pPb/7k/4K3/3p2P1/8/8/8 w
d
search g8=N+
move
will not work. Crafty says: Illegal move (ambiguous): g8
5) setboard 4k3/nnnnnnnn/8/8/8/8/RRRRRRRR/4K3 w
move
will crash Crafty.
Personally I find 3) the "insufficint material feature" quite annoying
and would be happier whithout it.
Kind regards
