Hello,
What could be the reason of black's blunder 21 ...Txb1 ? Is it again the cygbin story ?

Why should it have sth. to do with the "cygwin1.dll" story,
as Chispa doesnt use that file at all?
Actually it seems that this version of Chispa sometimes has a
hashtable bug, because I could watch a (very)few similar big
blunders in RWBC too.
BTW what GUI was used in your example? In case it was not
Winboard or Arena, it could be also a wrong set up or
even bug in Chessbase too...
