Reprinted in Breuer's "Ideengeschichte" (1982) as No.187 where it is interpreted as a logical problem: "Der dreizügige Hauptplan 1. Sd6+? scheitert an S:d6! und der Blockung des wBb3. Nacheinander werden diese beiden Hindernisse durch Wegelenkung beseitigt = Typ I der Vorplanprobleme." (Classification of logical foreplan problems by W. von Holzhausen, see p. 32 of "Ideengeschichte")

"From cradle to grave, everything we do is motivated by the need to answer one question: Who am I."
Ken Liu (* 1971) “Dispatches from the Cradle: The Hermit—Forty-Eight Hours in the Sea of Massachusetts,” 2016.

Just one forced line starting with a R-sacrifice to deflect bNf7 from d6: 1. Rg5+ Nxg5 (interposing on the fifth rank leads to a mate in 4) 2. c4+ bxc3 e.p. 3. Nd6+ Ka5 (Kb4 4. Nc6#) 4. b4+ Kxb4 5. Nc6#. Not the transposition 1. c4+? bxc3 e.p. 2. Rg5+ Qf5! and mate is delayed by one move.

Adolf Ferdinand Svanberg (* 1.10.1806, † 27.9.1857) Swedish composer from Uppsala.
