Why can't the black King kill the Queen?


White has 9 pieces and a Queen, and one of these 9 pieces is protecting her Majesty. I will let you find the one.

White has 9 men and a Queen, and one of these 9 men is protecting her Majesty. I will let you find the one.
Fixed that for you.
The word "pieces" excludes Pawns.
The word "men" includes both pieces and Pawns.
The OP is a new-ish player, and he hasn't developed any board vision yet. Why not just tell him that the queen can't be taken because it is protected by the bishop on b2?
