Update of the CONSULT database
The consult database contains the computer history of the current position from top-rated engines (3000+ elo) and will be updated frequently.
Reference : consult\3000.dat
Positions : 15.265.979
[Comp File = consult\3000.dat]
[Display Max = 10]
Maximum = 195
The computer list with depths and scores contains only the results of single threated engines rated above 3000 CCRL. With almost 11 million positions it start making sense to maintain such a database.
. CCRL 40/40
. CEGT 40/20
. CEGT 40/120
. CEGT 5+3 PBON
. TCEC season 6-13
. others, minimum time control of 15 seconds average.
Two tournaments (TCEC and CCC) receive special attention because of the massive hardware in use.
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.
