Hurricane Betsy [1]
Betsy,
a WinBoard compatible chess engine by Landon Rabern, written in C with a little Assembly, released in September 2000 [2].
Originally written in Pascal with its own text interface it was rewritten in C using rotated bitboards. Betsy applies PVS with null move pruning, and various standard and some aggressive non-standard extensions and reductions.
According to a former Arena site, Betsy was the first published chess engine able to play Chess960 [3], and was therefore Arena partner engine.
