First two solutions linked by Indirect battery formation by Bishop with rook. The 2&3 solutions show mutual battery formation.
Hm.... the triple avoidance is not so prominent here. In each solution one of the self-blocks is prevented and of the other two one works, the other has a weakness. I think the elements of Stocchi are there. That in each solution, one of the possible selfblocks is impossible could be considered by some as a weakness.
Fully agree that the cook 1.Qc3 is disharmonic

1. Qg6 Se2 2. Kh5 Sg3#
1. Rg6 Sg2 2. Kh5 Rh4#
1. Sg6 Se6 2. Kh5 Sg7#
Stocchi achieved with remarkable accuracy and economy (E.Rauly)
Delightful avoidance effects in this little gem (B.P.Barnes)
The 3 Selfblocks and battery openings are well shown , but repetation of Black 2nd move is a slight defect (M.Ridely)
Another breath of fresh air from Canada (R.Brain)
