Wie es aussieht, kommt Fat Fritz bald mit Fritz 17 zu allen Computerschach Fans. Ich habe den Vorläufer von Fat Fritz (u.a. DeusX) einige Monate lang
auf Schach.de beim Spielen beobachtet. Schon im Dezember 2018 sah ich grossartige Partien. Hier sind zwei Kostproben:

DeusX - Brainfish 1-0, 16m+5s


DeusX hat eine Traumstellung erreicht, und zeigt mit grossartiger Technik wie man gewinnt.

Folgende Partie hat mich geradezu begeistert: Wie hier Weiss aus scheinbar Wenig viel erreicht!

Ob diese Stellung bei genauem schwarzen Spiel für Weiss gewonnen ist, kann ich nicht sagen, aber wie Weiss hier nun weiter spielt, ist überragend!



Jetzt folgte h4! und später h5! Und Schwarz wurde überspielt.

Nun ist Fat Fritz da, und man darf annehmen das der sogar Einiges besser kann als seine Vorläufer. Derzeit kann man Fat Fritz schon in der Engine Cloud von
ChessBase mieten (und auf dem Server auch spielen). Dort läuft die Engine auf 2x RTX 2080 Ti. Die folgende Partie spielte jemand der die Engine gemietet hatte.

Solche Stellungstypen muss man mit AB Engines gegen NN Engines möglichst vermeiden, aber wie Fat Fritz spielt, ist schon Klasse.
