[what is this?]

First developed on a TRS-80, it is programmed by Ed Schröder, and Jeroen Noomen also assisted with its development. Later on, it changed its name to Gideon and ported to Mephisto (Computer) hardware devices, Microsoft DOS and Windows, and 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 (Computer) 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.

  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:

It may be run under WinBoard, Arena, or most of the Chessbase interfaces. You may download it free of charge here:

(: ♗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
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 <> 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!
