----------------------------------
I'am only using an AMD 266 Mhz with 64 Ram! I let Fritz run for almost 4 hours
which should simulate a faster (1,000 Mhz) processor running around 1 hour.
Fritz 7 didn't find "Re1", but the line it uses wins back a Rook and the passed
pawns on the Kingside look dangerous for Black in the ending if played correctly

Terry
