before my seeing others’ comments: My easy-come (so doubtful) solution [arrived to through the 32-pixel, B&W, restartable-moving-pieces setting and “(?)”]: in view of the following possibility\s::::::
white re-guards spot west of black king before queen check from north [or from northeast without capturing or queen moves south] before north-knight mate\ queen check without capturing is second move before knight mate\ black rook starts to north before queen moves south before east knight mate\\ ,,,,,,,,,,,,,,,,,,,,, it seems [ re-verification is intended later on and before seeing others’ comments] that white's nbfive starts

"Most scientists today are devoid of ideas, full of fear, intent on producing some paltry result so that they can add to the flood of inane papers that now constitutes "scientific progress" in many areas." Paul K. Feyerabend, "How To Defend Society Against Science" (1975).

André Ferdinand Fossum (* 22.8.1899 in Vardø, † 16.1.1986) Norwegian composer and International Master. "André Fossum was one of the greatest non-Czech specialists in the world for Bohemian problems. He composed almost 200 Bohemian threemovers and became International Master for Chess Composition in 1980. He commented his own problems in "Sjakkoppgaver og studier" (1975). He also composed studies. One of his studies is commented in Norwegian by Jarl H. Ulrichsen in his article published in Sjakkhuset: "Norsk Studiekavalkade1" (pg. 10-11)."
