See further notes about the compilation and editing of UltraCorr-2019.
Even if you are not a correspondence player, you need a large and up-to-date CC database to discover the latest opening ideas, tested in deep analysis by strong players working in tandem with chess computers.
Many of the authors for the Quality Chess publishing company, for example, keep a close eye on developments in master correspondence chess and quote CC games in their books.
If you are a correspondence player, you also need UltraCorr2019 to find games by your upcoming opponents. You can prepare for your games by studying their opening repertoires and can use the database to find their weaknesses. Many CC lovers play with more than one organisation and sometimes under different versions of their name; we have done our best to standardise these. If you are searching for games by a new opponent, we recommend searching for surname and first initial.
If you are interested in the history of chess, and of CC in particular, you will also find that UltraCorr-2019 includes many thousands of games from the postal chess era which are hard to find elsewhere.
