I added Ruffian 1.0.1 and Ruffian 1.0.5 (included in the free Arena Setup files,
Ruffian is a partner program from Arena Chess GUI) on the CD too, but not the
Linux versions or Mac OSX versions from the older Ruffian versions.

About Ruffian
-------------
Ruffian 2.0 by Per-Ola Valfridsson (Sweden) is the
strongest Winboard compatible engine in the world today.
The freely available and downloadable version of Ruffian
(ver. 1.0.5) is placed first on the Winboard Engines
Rating List. Its successor, coming more than one year
later, with improved features and much higher playing
strength, compared with 1.0.5.
Ruffian 2.0 is not only capable of holding his own
against the strongest commercial chess programs in the
world, but also able to compete successfully against any
of them.
- WB I / II & UCI Ruffian 2.0, Ruffian 10.10 Leiden!
- Linux / Mac OSX Ruffian 2.0
- 11 playing levels for UCI Ruffian 2.0!
- 4 different opening books by Prof. Dr. Djordje Vidanovic!
- Arena Chess GUI 1.0 by Martin Blume!
Ruffian 2.0 is a much improved engine that is considerably
stronger than version 1.0.1 / 1.0.5. More chess knowledge
has been added and many other areas have been enhanced
and improved. Piece mobility has been completely rewritten
and the new version has a more active positional playing
style. The engine is written in portable ANSI C and has
been tested on a number of platforms such as Windows,
Mac OSX, Linux, Solaris, Pocket PC and PalmOS.
Ruffian is a fast program that reaches high search depth
very quickly, and this gives it excellent tactical
abilities. Extensions, pruning and evaluation have been
carefully tuned to maximize Ruffian's playing strength.
Mobility is based on precalculated tables that can
recognize special patterns; this is one of the major
evaluation terms. Ruffian has a lot of endgame knowledge
and can play endgames fairly well. With the combination
of endgame tables, Ruffian knows when to convert to a
winning endgame. Search is based on iterative deepening,
principal variation search algorithm (PVS), extension,
SEE, transposition tables, recursive null-move and
forward pruning.
