Given I) just invoke "Header search" set the ELO values for both players to 2400-4000, insert Kupreichik as name for the white player, check that "No" is selected in "ignore colours" line, use "AND (restrict filter)" in the header search, hit "Search" and you're done. > *II) create a single "reference" database for me:* > > There are five large free databases out there: the 1.74 million games > database > <http://www.top-5000.nl/dl.htm?file=dl/Million%20Base%201.74.rar>, the > ICOfY IB109PGN database <http://sourceforge.net/projects/icofybase/>, > the UAB CIS "enormous" database > <ftp://ftp.cis.uab.edu/pub/hyatt/pgn/enormous.zip.>, the Chess Analysis > Project database <http://cap.connx.com/>, and the Encyclopedia of Chess > Openings database <http://observer.homestead.com/openings.html>.

Not cause of bad info in the spell checking file, but simply cause names are not unique and especially as foreighn names are usually transcribed to some target language. IMHO the problem is not to create a really huge DB but to get a suitalby large good DB. Quality is surely an issue here. It could well be that it's better to stick to only one of the sources you list above to get a better base at the end of the day. > Would that give me a good single-source 'reference' > database to do opening reports, player reports, update > weekly with TWIC, etc?

Well you could fetch RefCorr and TWIC from http://www.stellarcom.org/scid/RefCorr.zip http://www.stellarcom.org/scid/TWIC.zip They're not that large as your project however. (RefCorr is essentially a merger of CC games, TWIC is what it says it is ;) -- Kind regards, / War is Peace. | Freedom is Slavery. Alexander Wagner | Ignorance is Strength. | | Theory : G.
