CQLi written by Robert Gamble, is a high-quality, efficient and robust implementation of the CQL 6 language.

CQLi also has a number of new features that CQL 6 does not support, including support for "imaginary" positions that do not occur in the game tree; Unicode; and communication with external programs.

CQLi is extremely well-architected and accurate, and typically runs much faster than CQL. (Much of CQL 6 was tested and debugged by testing it against earlier versions of CQLi)..



NB. Other information about CQL on this website is still based on the older version 3.02 or version 5.1.
