Here is my modest 'Organised Disharmony' attempt.


1.Kc1 Bf2 2.d1=B Be3 #
1.Kc2-Bxd2 2.Ka1 Bc3 #
1.Kc3 Rxd2 2.Bd3+ Re2 #
First two solutions linked by Indirect battery formation by Bishop with rook. The 2&3 solutions show mutual battery formation.

The Stocchi theme requires three blocks on the same square with triple avoidance. There's no Stocchi here.

Quoting Harry Fougiaxis:
The Stocchi theme requires three blocks on the same square with triple avoidance. There's no Stocchi here.

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.

Stocchi theme here is a wrong label as in most cases in the databases.
Fully agree that the cook 1.Qc3 is disharmonic

Raju sends this interesting problem for comparison. Here the dual avoidance is more prominent but weakness is the repeated B2 move.

here is the official comments frm magazine ----:---

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)
