Subject: Important: Never use WB-adapter of May 2001 with Shredder5 under CB-GUI

The recently published match result of 17.0-3.0 between TheKing 3.12 Utz10b vs
Shredder5 UCI played under ChessBase-GUI [40/40' on K6-2 533/32 MB hash] was
titled as sensational but a lot of people guessed there would something be
wrong. Although 95-98 % of the moves could be reproduced in the analysis mode
under the Shredder5-GUI the severe loss of Shredder5 seemed suspect. Mogens
Larsen assumed a problem with the WinBoard adapter used. And after all, I must
say he was right. I had played the match with the WB-adapter of 24th May 2001
and this one should never be used with Shredder5 under CB-GUI.

I repeated the match, this time using the WB-adapter of 23th November 2000 and
obtained the following results:

P3 650/32 MB hash: TheKing 3.12 Utz10b - Shredder5 [10.5-9.5] 40/40'
K6-2 533/32 MB HT: TheKing 3.12 Utz10b - Shredder5 [11.5-8.5] 40'40'

These results look very realistic since Shredder5 does not feel comfortabel on
the slow hardware.

Important conclusion: NEVER USE THE WB-ADAPTER OF 23TH MAY 2001 WHEN PLAYING
WITH SHREDDER5 UNDER THE CB-GUI.

Regards
