I think stefan use a different interface and not the chessbase interface.
Stafn developed interface of himself and he is selling shredder not from
chessbase.

another bug is that it adjudicate games of engines(I remember cases when it
decided about a draw when the evaluation was 0.00 for some moves when the
engines did not agree about draw)

Another bug is that it claim a draw for the engine by 3-fold repetition and the
claim may be wrong(it is one of the reasons that I did not want to use it in
WCCC)

look at the following compsed game

position repeated only twice because in the first time enpassent was legal but
the chessbase interface does not care and claim repetition by 3 fold repetition.


[Event "40'/40"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "agur"]
[Black "Fruit 2.1"]
