Chronos, a WinBoard compatible chess engine developed by Guillermo Filia, written in C or C++. The project started in 2008 based on Guillermo Filia's earlier chess engine named GFC, and initially incorporated NagaSkaki's Shifted Bitboards approach to generated sliding piece attacks , later replaced by Rotated Bitboards following Robert Hyatt's tutorial.
