The Coven was an independent computer games developer with its roots in the Doom and Quake communities. Originally founded by John "Gestalt" Bye in late 1996, The Coven worked on a free Doom II add-on before moving on to Quake and going commercial in the summer of 1997. The Coven was closed in the winter of 1999, and all their work is now available for free.
QBC allows you to move freely around the board when selecting your chess pieces, and MORPH into the one you selected. You have full control!!!! One thing that will make QBC rise above any other quake patch, is INTELLIGENCE. QBC can tell if you have made a correct move, castle, enpassant, capture, promotion to any piece. QBC can tell if you are castling through check, incheck, giving the opponent a Check attack, but the most amazing fact is still to come.... QBC can determine CHECK MATE and STALEMATE!!!!!!!!!!!
