Задача 111 на S.K.Balasubramanian от Индия е отлична комбинация между фееричните условия Take & Make и KoBul Kings.

a) 1.Bb1 (Rb1?) Re8 2.Be5+ Rxe5-a1(bK=rB)# (3.Sxa1-b1??)

b) 1.Rc2 (Bc2?) Bg2 2.Qa1 Bxf1-b1(bK=rR)# (3.Qxb1-c2??)

-Dual avoidance by black.

-Checking unit cannot be captured as the square for “make” move is blocked.

-Mutual exchange of functions between BRc1 and BBd3 (mutual interference/mutual selfbolock for anticipatory make moves).   (Author)

KoBul Kings: When a piece (not a pawn) of his own side is captured, a King transforms into a Royal piece of the same type as the captured one. When the King is in the form of any Royal piece and there is a capture of one of the pawns of his own side, he becomes a normal King again.

Take & Make: Every capture ("take") must be complemented by a further step ("make": not a capture) by the capturing piece, using the movement of the captured unit, otherwise the capture is illegal. Pawns may not end up on their own first rank. Captures on the promotion rank lead to promotions only if the pawn is still on the promotion rank after the "make" part of the move. Promotions at the end of the "make" element are normal.
