b) 1…c8Q 2.g1B Qe6 3.Ba7 Lib6 4.Kb8 Qc8#

 

Koko Chess (Contact Chess): a move is legal only if arrival square is adjacent to any piece, this applies also to the capture of king. 

Lion (LI): Hops on Q-lines over any one unit (the hurdle) to any square beyond the hurdle.

Mate on the promotion square is nice. Wish the first solution had a similar mate by the knight.

Even that it is not on the mating move in the first solution the promoted wS also make switchback on the promoted square on the 3rd move. We should note also two black pieces play on a7 square and some interesting specific KoKo effects.

Yes. There is switchback in the first solution also. Added to the promotions of g2 pawn, makes a very good effect.
