Hello Stefan,

I thought that the original post was interested in the output from the dump but
you may be correct in that they are interested in the results of analyzing a
game and the evaluation and comments that Shredder inserts.  I just save the
analyzed game back into the original pgn file.

I use Shredder 4 for my analysis and it finds lines that some of the other
programs don't.

Congratulations on your recent IPCCC 2000 win.  Shredder is tough.
