At which move, Martin0?
Bulldog chess with Witch JunyJunebug - evert823

Black pieces can go trough the black Witch and all pieces adjacent to the black Witch.
White pieces can go trough the white Witch and all pieces adjacent to the white Witch.

That's illegal. You're in check since my Queen gives check right through your Witch - because she's now adjacent to my Witch.

She makes all adjacent pieces transparent for friendly pieces.
^ wait, but my witch isn't a friendly piece...
"The witch is transparent to friendly pieces, and she also makes all adjacent pieces (friend and foe) transparent to friendly pieces"
Which means that my pieces attack through any piece (black or white) if it is adjacent to my Witch. And my pieces attack through my own Witch.
Didn't the knight go to d4?
