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)

So weit, so gut, aber eine mit zwölf Bauern überladene Stellung.“ Diese Meinung hatte er allerdings exklusiv, was die weiteren Kommentare belegen. „Nach Königsrundlauf, sL-Befreiung und Exzelsior mit Unterverwandlung folgt ein schönes Mustermatt. Ich habe ein wenig Zeit verplempert, weil ich ursprünglich mittels Kf6 den Springer befreien wollte. Sehr gut, dass der Autor wieder dabei ist“ konstatiert GJ. „Dass der schwarze König den zweiten c-Bauern auch noch beseitigen muss, hat mich ganz schön auf Trab gehalten. Es wollte einfach nirgendwo ein Damenmatt funktionieren. Am Ende sind Pferd und Exzelsiorbauer beide die Stars der Manege – standing ovations!“ (RJ)
