====== Computer-Chess Wiki ====== ===== Lists ===== ===== Private Engine List ===== This is intended to be a complete list of all PC-based chess engines that are not freely available for download. Such lists can get outdated quickly as new authors introduce new engines and older authors lose interest, drop out of the computer chess scene, and notify no one. Luckily most authors no longer prefer private versions because public versions get more attention and testing.
