Und auch wenn die HV nicht und nicht zu stimmen scheint, wenn man sich das 2... b6+ näher anschaut, ist es eigentlich eine Nebenlösung, das führt zwar nicht zum Patt aber auch zum Remis durch Dauerschach.
Nur zum Beweis, dass das ein Ausweg von Schwarz aus dem sicher auch gefundenen Patt ist, die Hv mit 2... cxb5 einzugeben, bringt gleich:

Dürfte allerdings ein schlechter mp- Versuch gewesen sein, auf einem 3Ghz Kern hatte er es nach 6 Min, 1.0 nach 3.
Schon lange her, dass eine neue Version weniger Nullzug hatte (zumindest bei so wenigen Figuren) als die Vorversion.
Sehr erfreulich, gerade bei einer engine, die schon lange (bright mitgerechnet) eine meiner liebsten war.

P.S. der konnte das andererseits noch flotter:

Lustig, Kay!

Zum Thema Oldies Goldies hab ich noch Comet B68 und Fritz 5.32 probiert, beide auch nicht schlecht.

8/kp6/1Rp5/8/1KP3p1/1P6/PP6/8 w - - 0 1

Bei Fritz 5.32 besonders witzig: er flüchtet als Schwarzer vor dem Patt von Weiß auch in die 2... b6+ Nebenlösung, so wie Spark 1.0:

Auch hier zum Beweis, dass das berechnet wird, weil dadurch das frühere Patt durch das spätere Dauerschach vermieden wird, die Eingabe der HV mit 2... cxb5:

8/kp6/8/Kp6/2P5/1P4p1/PP6/8 w - - 0 1

Auch hier unterbleibt in der neuen HV die Umwandlung, die Bewertung stimmt aber und das Zumachen der weißen Stellung, ich glaube, man kann davon ausgehen, weil Schwarz die Sinnlosigkeit der Umwandlung "erkennt".

Man könnte sagen, was die engine- Entwicklung angeht, der Kreis schließt sich und Alles schon mal dagewesen, so defätistisch bin aber nicht mal ich.

Es ist einfach eine Stellung, die mit weniger nullmove pruning schneller gelöst wird, wie die Fritze mit der Option Nullzug aus zeigen.
Auch Houdini schafft es dementsprechend, ich glaube, er hat auf Quad so 3 Min. gebraucht bei mir.

Schaffen eure Computer auch diese Remisstudie?
Probiert es aber vorher mal bitte ohne Rechner.
