In the second position my Fritz plays Rxd1 immediately which wins. Nimzo and Junior also play these moves. It's not a matter of "believing" anything. It's simply a matter of reading what's on the CD. My guess is the CD ROM has many errors on it and Chessbase can't find/fix all of them with a patch. Obviously a New CD ROM with no errors is out of the question so we are stuck with BUGS BUGS BUGS !
