Hello,

here my compressed results of new Ruffian versions in test suite
"Weltmeister-Test" (WM-Test) - with permission of Ruffian author Perola
Valfridsson:

a) <b>Ruffian 2003-10-10</b> version (and winner) of the CSVN tourney Leiden
2003, *.exe file 2003 Oct 10th
b) <b>Ruffian 2003-10-29</b> devel ("post Leiden"),*.exe file 2003 Oct 29th -
and for comparing
c) <b>Ruffian 1.0.5</b>.

All Ruffian versions were tested as UCI engines under Shredder Classic GUI with
256 mb hash and access to the complete 3/4/5-men Nalimov tablebases;
hardware: AMD Athlon Thunderbird 1400 mhz.

The test suite "WM-Test" (by Dr. Michael Gurevich and Heinz-Josef Schumacher)
includes 100 test positions from games of the different (human) chess world
champions: 38 positions in king attack, 36 positions in positional playing and
26 positions in endgame.

For comparing the following Ruffian results with 204 other engines (all
professional ones and many Winboard/freeware engines) please have a look at
[http://www.computerschach.de/test/index.htm] with detailed results in Excel and
the 100 test positions.
