Do any of you have experience with the databases offered (mostly for a price) at the "Opening Master" site - http://www.openingmaster.com/ . It's based in Slovakia.
I got my hands on "version 1.31" (created just a few days before the current 2.01), and I don't like it. I was tempted to subscribe to their service - but I think I will stick to TWIC and http://www.chessmix.com . Note the large number of player and tournament names (compared to my own well-edited database), which means lots of editing is needed (or which wasn't done before the database was made available to the public). I found my name spelt 5 different ways.
Looking at the 1200+ games under my name, there are classics such as all 24 games from a match I played against Howard Streit in 1967 (I think this was the first time we ever used a clock) - and about 50 games with no tournament name attached to them. Although the database goes up to 2010, I couldn't find any of my games later than 2007.
Another example - Thomas Roussel-Roozmon. His name is spelt 10 different ways. None of his games played in Canada since 2008.
"Korchnoi, Viktor" is spelt 18 different ways.
The 2010 Edmonton International is under (at least) 3 different variants of the name.
Some comparisons between their database and mine:
OM: 5,862,783 games. A duplicate check showed 30 doubles (not bad),
Mine: 4,468,680 games.
OM: 776,547 player names
Mine: 284,976 player names
OM: 342,426 tournaments
Mine: 59,408 tournaments
