Atlas,
an UCI compliant chess engine by Andrés Manzanares Campillo written in C++ - executables running under Linux and Windows.
The development of Atlas started in 2004, initially representing the board as 0x88 vector attacks mailbox along with piece-lists,
supporting WinBoard, and written in C. Atlas 2.90 was a complete rewrite released in June 2011, a bitboard approach only supporting UCI [2].
