If Pawn-b4 or -c4 moves, Dragon-a6 has one pathway.
If Pawn-d3 moves, Provoctor moves g7-f6-e5(piece-d4)-e4-e3-e2-e1.
If Pawn-i3 moves, Dimaecher has pathway i7-i6-i5-(piece-i4)-h4-g3-f2-e1.
If Cardinal-f4 moves, Wolf has pathway g8-f7-f6-f5-f4-f3-f2-e1.
King cannot move because of both Canons' and Flamingo's covering all.(16)
