Virtual Chess,
a commercial chess program by Marc-François Baudot and Jean-Christophe Weill market by Titus. It is the 32-bit Windows version of the Virtua Chess MS-DOS program and commercial fellow of Écume aka Cumulus 2. Virtual Chess was further ported to the Nintendo 64 Video game console released in 1998 as Virtual Chess 64, featuring a 3D Graphics Board with animations similar to Battle Chess. Virtual Chess participated at the WMCCC 1995, and became two times Professional World Microcomputer Chess Champion [2] at the WMCCC 1996 and WMCCC 1997 (runner-up behind Junior). In 1997, Virtual Chess won the 5th French Computer Chess Championship and participated at the WCCC 1999. Beside other human-machine matches [3] , Virtual Chess played the Harvard Cup 1995 and the Aegon 1997 [4] .


given in 1999 from the ICGA site [5] :

Virtual Chess is the commercial version of the Écume 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 Étienne 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 [6] .
