SBD: The WB can be moved to h1 with a long bishop sweep, one solution.

However the BQ is something of a sham, unless there is some try play I am missing, which would not have been common in 1957, the BQ can also be a BR (with the WBh1). still C+. A BB on e6, still C+. All you need is proper dual avoidance between the piece performing the block on f5 and the block on e5.

An example FEN, just to be sure, with the Black bishop performing the block on f5:

7K/4p1R1/4b3/8/8/3kP3/8/7B b - - 0 1

Or from the diagram, -BQe5, +BBe6

Adrian Storisteanu: Nice cleanup, Yuri! I'd also set bPf4->f3 for an ideal mate (at the expense of a bit of a capture move)!? And, even bRh6->g6, so the bR already blocks the bK at the start, but it's just a wrong block (though a hint of things to come)... :-) (2021-06-13)

'DAZ'-Lösungsanalyse: "Den starken Drohungen des Schw. (Dxe8, Tb3-a3,h2-h1=D) kann Wß. nur durch starke Mattdrohungen begegnen. Als solche ergibt sich 1. Sd4-f5, was 2. Da1-h1+ und 2. Da1-a6 (--c6 oder b7) droht. Die stärkste Erwiderung ist natürlich Dh8xa1, worauf Sd7-f6 matt folgen könnte, wenn die D von der Deckung des Feldes f6 abgesperrt werden könnte. Das erreicht aber Wß. durch 2. c2-c4+, worauf Schw. b4xc3ep spielen muß und Sd7-f6 matt setzt. Nun hat Schw. gegen 2. Dh1+ auch die Verteidigung La7-g1, was auch die Fortsetzung 2. Da1-a6 (wegen Dh8-a1) ausschließt. Dann schließt aber Wß. durch 2. e2-e4+ f4xe3ep die L-Schräge und Sd7 gibt auf b6 matt. Nicht minder fesselnd gestaltet sich das Spiel, wenn Bd3 von einem T geschlagen wird: 1. ... Tb3xd3 2. c2-c4+ b4xc3ep 3. Da1-a2 matt und 1. ... Th3-d3 2. e2-e4+ f4xe3ep 3. Da1-h1 matt. In diesem Fall wird durch das erzwungene Kreuzen ['DAZ'-Sprechweise für "en passant-Schlagen"] der betr. T verhindert, zwischenzusetzen. Die Aufgabe, die also mittels des Kreuzens einmal die Sperrung zweier Schrägen, das anderemal die Sperrung einer seitlichen Turmreihe durchsetzt, ist ein Meisterwerk ersten Ranges."
'DAZ' gibt als Quelle "1. Preis Strategie-Turnier 1908" an.
F.Chlubna (s. Ndr. Vers.Schätze) gibt "Ehrende Erwähnung, La Stratégie 1908-09 " an. (db)

In der Schwalbe (s. Nachdruck) wird 4. ehrende Erwähnung angegeben.

Hier Dreizüger-Thema B2, Ausschreibung 2. WCCT 1980: Im ersten Zug wird Schwarz gezwungen,
eine gefesselte s. Figur D,T,S,L (nicht B) zu behindern (Verstellung oder Block auf
einem Feld). Dies ermöglicht Weiß die Entfesselung der s. Figur durch einen s t i l l e n
zweiten Zug seiner fesselnden Figur (also direkte Entfesselung).
