'''[[Main Page|Home]] * Dictionary'''
This page is intended as a dictionary, glossary or proxy of common chess programming terms. It is intended to facilitate the navigation, especially for the pages that do not have a clearly defined ancestor, and as a cross-reference between the pages containing similar material covered from the different angles. The latter situation might indicate that some kind of merging or re-editing is necessary.
