Sissa. Move exists of moving a number of squares as rook and an equal number of squares as bishop.[All Comments] [Add Comment or Rating]

The answer is NOT because it is a slider whose move is composed by two stages: first like bishop followed like rook; or viceversa, first like rook followed like bishop; and those pieces are reached by two different paths.

For the sake of clarifying the matter I'm updating the diagram replacing the Rook by a Bishop because otherwise the Sissa would be pinned and then obviously it could not be moved except for capturing the Rook.

From c3, Sissa can reach the squares marked with green circlets by moving nightrider-wise; squares marked with red circlets are reached by moving rook-wise. 

The i6 square is reached by c3-f3-i6. The c3-f6-i6 path is obstructed by the Blue's King. Likewise, f9 is reached via c3-f6-f9, not by c3-c6-f9 that is obstructed by the Bishop.

c8 is reached via c3-h3-c8, not via c3-h8-c8 that is obstructed by the g8-Pawn; c1 is reached via c3-a1-c1 or via c3-a3-c1 but not by c3-e3-c1 nor c3-e1-c1 that are both obstructed by the d2-Pawn.

a2, a4, b5, d5 and e4 can be reached by moving either like Mao or like Moa; b1 only like Moa; d1 is inaccessible due to the obstruction of White's King and d2-Pawn.

Concluding, the Bishop can be captured by 4 paths: c3-e3-c5 or c3-e5-c5 or c3-a3-c5 or c3-a5-c5. The Queen can only be captured by c3-e5-e7 since c3-c5-e7 is obstructed by the Bishop.
