PR Josef Breuer: "Man glaubt auf den ersten Blick, das Ende einer Glanzpartie vor sich zu haben, aus der man kurzerhand einige überflüssige Steine (wie die weißen Bauern) herausgeschoben habe; aber dann entfaltet sich ein reizvolles und unerbittliches strategisches Spiel, das in allen Phasen einzig von der schwarzen Rochade bestimmt wird. Gewiß ist die Schlüsselfigur ein reiner Störstein, aber er ist so sinnvoll harmonisch eingesetzt, daß seine Existenz und Aktion geradezu das Salz des Geschehens bildet."

Zwar mehr nur ein Schema, die nach dem 3. weißem Zug ent-
stehende Zugzwangstellung (KD/KSS) dürfte aber nicht uninteressant sein. Nebenbei: ein einfacher Fall von Asymmetie - symmetrisch wäre als Lösung. De4? mit der Doppeldrohung 2. Dxh7# und Dxh1#.
