Loyd in "The Musical World": "We give, this week, two positions taken from actual play, so as to show how necessary problem study is to make the finished chess player; for it is acknowledged by all chess writers, that the study of problems is indispensale to a player before he can learn how to play the termination of his games correctly. ... Problem IX is the termination of a game recently played at the rooms of the Hudson County Chess Club. We are sorry that we cannot give the moves of the game, as it was very pretty. The termination, however, is well worthy of an examination, as it takes very good play to win."
SBD: Cooked, of course in that 2. Sd4 works as well, as well as the dual mate 8. Da4/b3#, although I am certain Loyd would not see these as defects based on the idea he was trying to show. (2012-02-23)
athulin: In Chess Strategy, p. 246 (but not in White?) Loyd expands on the original story:
"... the committee who were pitted against me
abandoned the game as drawn, which I willingly
accepted, telling them, at the same time, that they
had a forced mate in eight moves. After being informed
of the fact they were unable to discover it." (He also modifies the name of
the club to Hudson City Chess Club.) (2022-08-21)
athulin: ... and in Chess Strategy Loyd also states that he was playing the game blindfolded ... (2022-08-21)

Das breite „V“ punktet vor allem durch das überraschende Opfer 7. Dgb7! und das abschließende Mustermatt. (F. Fiedler)

Forderung: Konstruiere ein Schachproblem deiner Wahl (außer Märchenschach) in Gestalt eines V (=
Victory) und besiege das Coronavirus der zweiten Welle.

Das Turnier fand im Frühjahr 2021 statt. Initiator und Turnierleiter war erneut Matthias Hentschel.

Das in der Ausgangsstellung vermutete Matt ist vorerst nicht spielbar, kommt aber nach geschickten Rangiermanövern am Ende der Lösung doch noch aufs Brett.
Die weiße Dame und der weiße Springer müssen ihre Zusammenarbeit intensivieren, um den Blockwechsel auf h6 zu ermöglichen. Dabei legen die beiden weißen Protagonisten weite Wege zurück, ebenso der schwarze König, der durch alle weißen Figuren so im Zaum gehalten werden muss, dass er immer (mindestens) einen Zug zur Verfügung hat und nicht patt gesetzt wird. Nach der Rückkehr der weißen Dame und des schwarzen Königs ist endlich das geplante Matt möglich.
Mustermatt.
Miniatur.
Schwarzes Minimal.

Kniest und Maslar mit dem umgewandelten Turm, Bauer(Turm)-Rundlauf von d7 nach d7, Klasinc (weißer Bauer / schwarzer König) in b).“ (Autoren) BK war „verblüfft, dass es keine Nebenlösung mit der weißen Dame“ gab. JB entdeckte das folgende Detail: „In a): Der erwandelte weiße Läufer räumt das Mattfeld für den schwarzen König, die schwarze Dame blockt. In b): Der erwandelte weiße Turm räumt das Mattfeld für den schwarzen König, die schwarze Dame ist Schlagopfer.“ Insgesamt gibt es hier „eine Fülle von strategischen Themen, wie z. B. schwarze Opfer, konsekutiver Umnow, Klasinc, Kniest, Koschakin-Thema, Maslar, Platzwechsel von weißem Turm und schwarzem König, Umwandlung in Turm und Läufer bei Weiß, Rückkehr des weißen Turms, ein Mustermatt. Der hohe Aufwand an schwarzen Steinen hat sich hier gelohnt. Schwierig und schön.“ (KHS) Dazu sehen wir noch einen „Rundlauf des weißen Läufers in a).“ (TZ) „Ein großartiger Hit in Sachen Hilfsmattmehrzüger.“ (JA)
