On the bord of my opponent appiared 3 bishops in the begining of the game. I have screenshot.
just put a link to the picture in here
It's definitely broken, but I don't see the 3 bishops.
You were playing Crazyhouse, which means that after capturing one of your bishops he/she could place a bishop on the board as one of his/her moves.
move 16 you can see the 3 bishops.
Thanks for the answer about crazyhouse.
