Well done, slowbut2. You now covered everything. James's problem may be harder than Holzman's as it may be unsolvable :-)

before my seeing hint\s from others’ comments: My more complete solution [arrived to through the 32-pixel, B&W, restartable-moving-pieces setting and “(?)”]: in view of the following possibility\s::::::
black start captures knight before bishop check before pawn mate [or else black start moves west knight or east night ( attacks pawn) or pawn (and attacks knight) or other] \
black start moves west knight before white-knight check from southwest before queen mate\
black start moves east night (and attacks pawn) before queen to northwestmost
before queen or bishop mate\
black start moves pawn (and attacks knight)
before queen to northwestmost before bishop or knight or pawn mate\
white queen guards knight from southeastmost corner before pawn mate\ \\ ,,,,,,,,,,,,,,,,,,,,, it seems [ re-verification is intended later on and before seeing others’ comments] that white's qcone starts

black start captures knight before bishop check before pawn mate\ black-pawn start add attack of white knight before queen to northwestmost before black captures knight [or else - before knight mate ] before pawn mate [or bishop mate from northwest]\ black start doesn't add attack of white-knight before queen to eastmost before pawn mate \\ ,,,,,,,,,,,,,,,,,,,,, it seems [ re-verification is intended later on and before seeing others’ comments] that white's qcone starts

"The problem I have set myself is a hard one: first, to defend...'experience' against 'philosophy' as being the real backbone of the world's religious life...and second, to make the hearer or reader believe what I myself invincibly do believe, that, although all the special manifestations of religion may have been absurd (I mean its creeds and theories), yet the life of it as a whole is mankind's most important function." William James (1842-1910) in a letter on his "The Varieties of Religious Experience" (1902).

FIDE Album. 3rd Prize. A Bohemian problem. Something on 1.. KxN has to be found, so 1. Qa3?, Qc3? fail. The key 1. Qc1 threatens quietly 2. Qh1 3. c4#. On 1.. KxN 2. Bc6+ Kf5 3. e4#; 1.. Nc7 2. Nc3+ Kc5 (Kd6) 3. Qa3#; the star variation is 1.. Nf5 with the quiet 2. Qa3! (3. Nc3#) KxN, Nxe3 3. Bc6#, Qd3#. In the side variation 1.. f5 both 2. Qd2+, Qa3 work.
