To maintain the consult databate we are asking for PGN games or analyzed EPD files with score & depth from CCRL top-10 engines with a minimum time control of 15 seconds average. You can upload (preferable in zipped format) in our DROPBOX account anonymously.

Please note that we monitor CCRL | CEGT | TCEC | CCC and FGRL ourselves.
