About n.44 - I can say that unfortunatelly almost all H#2 are with schemes (or part of schemes) which are shown before... But I do not know some direct anticipation of this nice problem by Zivko Janevski.
In Zivco's No.44 the moves of the black king along the halfpin line could be novel. Hope it is so !
