Determine the maximum number of bishops that we can place in a

8 \times 8

chessboard such that there are not two bishops in the same cell, and each bishop is threatened by at most one bishop.
Note: A bishop threatens another one, if both are placed in different cells, in the same diagonal. A board has as diagonals the

2

main diagonals and the ones parallel to those ones.
