2019-12-05 11:12:30, by problemist: Comment by the judge Miroslav Havel in "Československý Šach," 1958, p.96: "Solidně vystavěná práce. Hrozbové pokračování králem 2. Kc7 (proč ne 2. Kb7?) i obě hry, z nichž jedna se subvariantou, zaujmou tichým průběhem."
2019-12-05 08:27:28, by problemist: It still is reprinted "Vybrané šachové skladby," somewhat hidden, as No. 31a (only the threat and the variation on 1.. e3 is mentioned) on p. 12 with No. 31 (a Roman decoy) being a #5 in Šachové umění, 1946.
2019-12-05 07:58:40, by problemist: The key by the wR to d4 threatens 2. Kc7 3. Be7 4. Bxb4#. On 1.. d2 2. Rxd2 (threat 3. Ra2#) b3 3. Rd4 (threat 4. N~#) b4 4. Rd5# and 1.. e3 2. Rxd3 (threat 3. Nd7+ Ka4 4. Nc5# or 3. Nc4+ Ka4 4. Nb2#) b3 and again 3. Rd4 b4 4. Rd5#. Simpler than expected by Bruno's rating and the 1st Prize. Also Pachman did not inlucde it in his collection "Vybrané šachové skladby."

Vladimír Pachman (* 16.4.1918 in Bělá pod Bezdězem, † 8.8.1984 in Praha) Czech composer and Grandmaster in composition, see wikipedia cs, de, it, lv, ru. "Vladimír Pachman is the brother of o.t.b. GM Ludek Pachman and the great-nephew of Bohemian composer Josef Cumpe (1868-1943). Vladimír composed about 1200 problems and studies, most of his problems in 3 or more moves. He was granted the title of International Judge upon the creation of the title in 1956. He edited the problems columns in "Ceskolovensky Sach" and wrote many books and articles. The following ones can be downloaded on the Internet:
"Problémový šach - Výběr 100 trojtahových úloh Františka Matouška" (1950) about F. Matousek's problems;
"České zvonky z Prahy" (1958);
"Šachová úloha" (1953), a treatise on direct mates with 239 examples, mostly three-movers;
"Vybrané šachové skladby Vladimíra Pachmana" (1979) about his own problems;
An article in Schach 1959: "Über das Wesen der Böhmischen Schule" about the Bohemian School;
Article in EG 61 (1980) "Logical Studies".
The quality of Pachman's works is high; he could include strategic and logical elements in Bohemian problems."
