Phoenix

a chess program by Jonathan Schaeffer, which in 1982 rose from the ashes of Prodigy. In the later 80s Marius Olafsson helped with the implementation of a parallel search. Phoenix and Sun Phoenix participated at four World Computer Chess Championships, the WCCC 1983, WCCC 1986, WCCC 1989, and WCCC 1995. It tied for first place in the 1986 World Championships. Phoenix further played seven consecutive ACM North American Computer Chess Championships, beside the mentioned WCCC 1983 simultaneously the ACM 1983, the ACM 1984, ACM 1985, ACM 1986, ACM 1987, ACM 1988, and ACM 1989.

In his 1987 ICCA Journal paper //Speculative Computing//, Schaeffer mentions //The Null-Move Algorithm// or //Don Beal's null-move//, and used it none recursively up to once per search path in his tactical scout solver //Minix// (Mini-Phoenix), which up and then gave the parallel running Phoenix, which was a less deep searcher than //Minix//, some tactical hints. || toc =Authors=
