CC+Sapiens

a computer chess project headed by Mikhail Botvinnik during the early 90s after the [|dissolution of the Soviet Union]. Further contributors, specially on the application of [|economic planning] (EC Sapiens) were mathematician Vasily Vladimirov, and the economists Evgeniĭ Dmitrievich Cherevik and Vitaly Vygodsky.

CC Sapiens was a trial to resurrect the Pioneer project with the aim to develop a chess program to model a Chess Master's Mind - ultimately terminated with Botvinnik's death in May 1995. Botvinnik's attempt to demonstrate the ability of CC Sapiens on three selected positions with narrow search trees in ICCA Journal, Vol. 16, No. 2 was criticized by Hans Berliner  and Botvinnik's old chess rival David Bronstein, due to obvious flaws and allegation of forged results. || toc =A Muse A-Musing= Excerpt of the Editorial, ICCA Journal, Vol. 16, No. 3 by Bob Herschberg and Jaap van den Herik :

=Kasparov - Ribli= The first one of Botvinnik's //Three Positions// and most criticized analysis is from the [|Garry Kasparov] vs. [|Zoltán Ribli] game, [|Skellefteå] [|World Cup 1989] , after 26.Rxb5 Bxe3  : CC Sapiens produced an analysis of a mere 18 nodes, and determined that this position is a win for White with Rd8. Botvinnik gives one variation with 1.Rd8! Qxb5 2.Qd6! Bxf2 3.Kxf2 Re8 4.Qe7, satisfying the stated goal, but missed to consider other alternatives of Black's first (1... Bxf2) and third move. Berliner: "Presumably the beckoning 3. ...Qf5+ is dismissed since it can't possibly lead to a win for Black. Botvinnik knows that, and I know that, but can a computer program figure this out without searching?". The blunder 4.Qe7 was apparently discovered by Botvinnik or his team just before press time, given in a footnote, but due to mistake of the editors, three pages apart.

Feng-Hsiung Hsu, who already analyzed the position with Deep Thought along with Gary Kasparov in 1990, posted the winning lines of 3. ... Re8 4.a4 or more difficult 3 ...Qf5+! 4.Kg1! in rgc as reply to Berliner's B* HiTech analysis  with the wrong 3 ...Qf5+! 4.Kg2 line. As admitted by Berliner in his //Playing Computer Chess in the Human Style// ICCA correspondence, it was possible to identify a serious bug in B* HiTech's search algorithm thanks to Hsu's information.
