Alexandre,


Thank you for the excellent position.  Junior 6a finds exactly that continuation
after 2min 54sec on a PII 333Mhz with 64Mb of RAM. It locked on to that sequence
after 4 minutes.  Thirty three moves later the H-pawn queened and it was white
with five pawns and a queen against a black rook.  Junior is worse in some
positions than Fritz but this is not one of them.  Soon we will see these
machines doing as well as the best GMs ie in about ten years from now.

A satisfied Junior 6a owner.
