So far,

Shredder 8 - Pro Deo 1.0, score after 16 games, 11.5-4.5.
Shredder 8 with 11 wins, Pro Deo with 4 wins.
Only 1 draw.

Shredder 8 Chessbase GUI, engine match

AMD 64 - 3000+, 768MB RAM

2' + 2"

Rebel personality 2

Each with own book, learning minimized to max in Shredder.

200MB Hash for each (for Rebel, w8 setting in Wb2Uci.eng file = 200MB hash)

All 3, 4 and 5 piece tablebases which Rebel did not seem to use. May? not have
been much of a  factor as no game reduced to that few ending pieces, but
Shredder consulted tbs regularly.

Rebel fast, ~ 1500+ kNs often, with Shredder ~ 400+ kNs (typical)

Even at this fast time Shredder seemed to consistently search 3-4 plys deeper
than Rebel, that is the first number in the search depth given by Shredder as,
for example, 12/31, compared to Rebel’s search depth.  Rebel only has one number
for search depth.
