Change of continuations to the first 4 black moves of Ph6.
In a) there are 12 white quiet moves (except 10. Bc5+) and 12 black quiet pawn moves (except 13...Kxf2#) in preparation for blocking of the black bishop.
In b) there are 8 white quiet moves and 8 black quiet pawn moves in preparation for active play of the black bishop. (Author)

"Two very interesting and hard-to-solve twins, with the white King traveling to distant squares and quiet moves by both sides.

Also worthy of mention in the specific change of play on the first four moves of both solutions after the black Pawn's moves." (Ivan Soroka)
