Each Bishop is attacking exactly 2 Knights, but no Bishop.

In a 4x4 chessboard, we can have this placement:
+---+---+---+---+ | | B | B | | +---+---+---+---+ B -> Bishop | N | | | N | N -> Knight +---+---+---+---+ | N | | | N | +---+---+---+---+ | | B | B | | +---+---+---+---+
This satisfies all the given conditions.
Thus, the required smallest dimension of the square chessboard is 4x4.
