Queen, a WinBoard and UCI compliant chess program with an own GUI written in C++ by Leen Ammeraal, first released in April 2000 [1], the WinBoard version in January 2001 [2]. At least earlier versions of Queen used NegaScout utilizing a transposition table storing both lower and upper bound scores with separate drafts but only one best move [3].
