Hallo,

folgende Stellung stammt aus einer Eigenmann-Testsuite:

8/8/R7/1b4k1/5p2/1B3r2/7P/7K w - - 0 1

Zu finden ist ein Zug der remis hält.
Mit 5Steiner findet bei mir keine Engine die Lösung.

Frage 1: Wie ist es mit 6Steinern?
Frage 2: Hält evtl auch Ta3 remis?

Gruß
W

Hi,

mit 6-Steiner EGTB findet Stockfish sofort das Remis

Auf drei Kernen (weil ich gerade die blöden Bayern verlieren sehe 3:0 für Wolfsburg

) und mit 6er Nalimovs.

Könnte aber auch MP Glück gewesen sein. Bei MP weiß man halt nie.

Hallo,

folgende Stellung stammt aus einer Eigenmann-Testsuite:

8/8/R7/1b4k1/5p2/1B3r2/7P/7K w - - 0 1

Zu finden ist ein Zug der remis hält.
Mit 5Steiner findet bei mir keine Engine die Lösung.

Mit 5Steiner Syzygy finde ich doch bei SF6 die Lösung !
