Liebe Schachfreunde
Ein exemplarisches Beispiel, dass selbst die besten Engines gewisse
Stellungen nicht richtig bewerten können, zeigt die unten stehende Partie.

Weiss hat mittel-/langfristist eine Verlsutstellung. Der schwarze Druck
auf der g-Linie ist gewaltig. Und nach dem unvermeidliche Läufertausch
Ld7-b5 kann Weiss nur noch passiv zuschauen, wie der Gegner seine Stellung
verstärken wird. Trotzdem sieht sich Deep Rybka 4 bei Ausführung seines
Zuges 23.Kh1 völlig ausgeglichen mit 0.00/17.
