Editing of Ultracorr-X is now almost complete. The database will include over 1,750,000 games, by about 124,000 players, played between the early 1800s and June 2017. Games from ICCF are only part of the collection which also includes thousands of games from IECG (the full database), IECC, LSS and other modern and historic sources.
Many of the games are annotated, and for the first time we are including our annotations to many rare pre-1914 games. We are still in the process of checking for recent games, improving data accuracy, and adding annotations to some games that are important for theory.
Tim Harding's correspondence chess databases used to be famous as the largest and most accurate collections of CC games to be made available.
Each was larger than the previous version and took months of work to compile, check, and edit. It is now seven years since the last revision.
Correspondence players need a reliable large database to prepare specifically for future opponents.
Over-the-board players need to consult a good CC database to see where computer-guided innovations have transformed many critical opening variations. The use of CC databases by several of the authors of Quality Chess books is testament to this.
A reliable CC database is also an important historical resource for chess historians.
Now the wait is almost over!!
Ultracorr-X is nearly ready and will be made available for purchase and download around 20 August, from this website only. The final price is not yet fixed but is likely to be around 55 Euro, with a discount for purchasers of our last database.
This database will be in ChessBase format, prepared chiefly in ChessBase 14, but also checked for compatibility with earlier versions of the program. It will only be available for download from this site, with payment by PayPal. We cannot supply in PGN because the file would be unmanageably large.
Further details will follow soon. To enquire further or reserve an advance copy, please email Tim Harding.
Please do NOT send PayPal payments for UltraCorr-X to that address as it is not the email address we use for payments. Just express your interest and we shall be in contact in the second week of August.
There were four biannual editions of the MegaCorr series between 1999 and 2003, sold chiefly to subscribers of our printed magazine Chess Mail. After the magazine closed, we produced three editions of an even larger collection, Ultracorr, up to 2007.
After that we were too busy with historical research and writing to publish any more but we always kept our personal collection up to date. Over the last six months we have been improving the data quality and eliminating doubles, especially correcting erroneous data found in other published CC databases.
It is impossible to make such a large database totally accurate and to eliminate all doubles but we believe that UltraCorr-X will be the most reliable database of correspondence games ever issued, of value to correspondence and over-the-board players alike.
