Awit

a chess program written by Tony Marsland. The original program, which played in the first ACM 1970 in [|New York] was called **Wita**. The name was derived from [|Witan], which was for a //meeting of wise men//. The inspiration for Wita came from the //1966 Fall Joint Computer Conference// in [|San Francisco] and had been impressed by Richard Greenblatt's talk about Mac Hack.

In about 1977, the name was changed to Awit for two reasons. First, to put the program nearer the top of an alphabetical list and second (more importantly) to reflect the program's propensity to play subtle moves that were rife with fatal flaws. Awit-Wita was written in Algol W and ran on IBM 370 under the [|Michigan Terminal System] (MTS). Awit is a selective Shannon type B searcher with a lot of chess knowledge implemented, and therefor with 8 Nodes per second extremely slow with an impressive strength / nodes-evaluated ratio, despite its inherent tactical flaws up and then. || toc =Quotes= Quote from the ACM 1980 booklet

=Achievements= Awit's greatest tournament success was the shared second place at the WCCC 1983 in [|New York], while almost the same program played its last tournament at WCCC 1986 in [|Cologne] only to serve as a benchmark for other programs. =Photos & Games=
