I am in doubt now whether the Ancaa wouldn't be a better Queen replacement
than BDD. The later is color bound, so I added an color-changing
non-capture to it to make sure it still would have mating potential with
either of the other two color-bound pieces. But an Ancaa is a color
alternator, and would not need such a trick. Which makes it look a much
cleaner piece.
The only argument against it would be that it looks too much like the piece
I had in mind as Rook replacement, the WN. Although the latter jumps to the
N squares, while the Ancaa can be blocked on F squares.
So I was also looking for an alternative for the WN. One possibility for a
strong piece without mating potential is the Gnu (NC). But it is a
16-mover, which would make it significantly stronger than a Rook, while the
forward 3-leaps are also not recommended. So I might make it a sort of
sliding Gnu, which can reach the C squares only via the N squares (but
still jumps directly to the N squares). This is not too much stronger than
a Rook, and it takes the sting out of the forward C moves.
