Umnov theme with ideal mates in set and actual play.[A]
The move 2.Rd4 cannot be considered as "Umnov" (in spite of the author's claim) because it is the arrival of the piece of the same colour (not a bicolour arrival as required by "Umnov" theme).[ZG]

Problem shows following combination: Black unpins white and does the anticipatory self-pin, simultaneously unipnning the mating piece. Pin-model mates, black Leibovici interferences. Two pairs of changed functions of black and white units (WR & WB, BR & BB) and complete D&L analogy of two solution. Meredith with no white pawns. Transformation of white direct battery.[A]
Reciprocal "Leibovici" interference and complex selfpins.[ZG]

Different placement of BK in pure and economical, but not ideal mates (since some black pieces are not used in the mating positions).[ZG]

Black unpins one of two pinned black pieces which subsequently opens one the white line and closes the black line. Meanwhile white interferes with black line-mover and mates utilizing the retained pin of another black piece. Complete D&L analogy between two solution and reciprocally changed roles of all thematic black (Ra4&Qh1, Rf7&Be5) and while (Tg4&Be2, Rh7&Bh2) pieces. Also, reciprocally changed destination squares for black and white second moves. No white pawns.[A]

GB Entry for 5th WCCT - Not placed.[A].
Six times WQ abandons one and creates another battery. However, the initial battery is not convincing since 2.c5 is the least expected mating move for the solver.[MV]

Mutual preventive unpin of Rb3 and Qf5, underlined by thematic tries. An idea I have been "obsessed" with as exemplified by two problems cited (for other reasons) in Mr. Janevski's article in No.8-9: p.298, without thematic tries (diagram 476a: [a] 1.Se3 Rf6 2.Qb4 dc6#, [b] 1.Qe5 d6 2.Sd6: Rb2# ), and p.280 with hidden thematic tries 1.Sb3? Rg12.Sd2 ??... and 1.Sd2? Bf3 2.Sb3 ?? (diagram 476b: 1.Sc3 Bf3 2.Sd7 Rb6#, 1.Sd3 Rg1 2.Sg3 Bd5#)... Without tries the unpinning moves are not convincing.[A]
Extraordinary battery-pin complex with accidental dual avoidance.[ZG] ign=top>
