Descriptions
- Description given in 1999:
Virtual Chess is the commercial version of the Ecume and Cumulus 2 chess programs. It holds the title of World Professional Computer Chess Program '97. Its most recent result : a 1.5/2 match win against GMI Etienne Bacrot at the Cap d'Agde tournament. It finished first (tied with Vaisser and Chernin) of the 1996 rapid Aubervilliers tournament.
The chess engine is written in C and 32 bits assembly. It is based on PVS, uses null move pruning and includes dynamic evaluation of king safety and pawn structure. The evaluation function attempts to build plans whenever it recognizes important features in a position. It runs on a PC with Windows (95, 98 or NT), with a splendid graphical interface written by the French firm Titus Interactive.
