10+7/8. A black bishop is missing. Drawn by repetition. (a) Add the missing bishop and prove there is only one legal square for it. (b) Give the moves of the shortest possible repetition loop.
Drawn: A position is drawn if (a) this position (pieces and move possibilities in the position) occurs for the third time; or (b) 100 half-moves have passed without a capture, a pawn move, or castling. This ends the game immediately. [I.e. if a position is drawn, either the last move is the first time a 3-fold repetition occurs, or it was the 100th half-move without capture, pawn move or castling]
