REBEL (COMPUTER) (born 1980) [what is this?] First developed on a TRS-80, it is programmed by Ed Schröder, & Jeroen Noomen also assisted with its development. Later on, it changed its name to Gideon and ported to Mephisto (Computer) hardware devices, Microsoft DOS & Windows, & the Apple II. After having experienced commercial success, it is currently free, going by another name which it has currently adopted, the Pro Deo version. For a short time, TASC produced Ch M Gideon WK as a small hardware unit for playing against REBEL (Computer) (aka Gideon) or The King (Computer) personalities, depending on which card was purchased. Chess Tiger (Computer) is a successor to some of its 11th major release version components.

Jan-31-05    BishopBerkeley: The strong Chess program known as "Rebel" has been renamed: it is now "Pro Deo 1." According to this recent rating list, it is the strongest of the free UCI Chess engines: http://wbec-ridderkerk.nl/html/Rati... It may be run under WinBoard, Arena, or most of the Chessbase interfaces. You may download it free of charge here: http://members.home.nl/matador/prod... (: B :) Jun-28-05    waddayaplay: I have submitted the game between Smyslov and Rebel played in April 2000. Should appear withing the next week :) Jun-28-05    PawnOfTheDead: So this is who David Bowie was singing about. Jun-28-05    csmath: Pro Deo is quite strong, it is very aggressive as well so it is a fun to play. At this point it is probably comparable to Fritz. Meaning it is as strong as Fritz and yet it is free. However there is no multicore/multiprocessor version which makes it significantly weaker on that kind of hardware. Jul-01-05    waddayaplay: If anyone wants info on its match with Anand in 1998, go here http://www.rebel.nl/anand.htm Dec-21-05    karlth: Is "Pro Deo 1" still the most "human" chess engine - as Rebel advertised itself? Dec-23-05    EmperorAtahualpa: I have submitted the REBEL - Anand games to the database. I hope <chessgames.com> will put them up soon. Dec-23-05    EmperorAtahualpa: I'm afraid that's just an advertisement slogan, <karlth>. You don't seriously expect a computer to imitate the human mind, do you? Dec-23-05    karlth: No human as in human playing style. Dec-23-05    EmperorAtahualpa: <karlth> That's what I meant. Sep-11-08    sallom89: Can Rebel hold it against Rybka 3? Feb-20-09    WhiteRook48: well, maybe he can REBEL against the match before it happens Jun-19-09    Octal: It's just a rebel with no cause. May-04-10    Raisin Death Ray: Has a bitter rivalry with Yank!
