The Opening Master GOLEM - biggest chess database out there

The origin of the word GOLEM is in question, probably the first occurrence was in the Bible. In Jewish folklore, a golem (/ˈɡləm/ GOH-ləm; Hebrew: גולם‎) is an animated anthropomorphic being, magically created entirely from inanimate matter. The word was used to mean an amorphous, unformed material (usually out of stone and clay) in Psalms and medieval writing. The most famous golem narrative involves Judah Loew ben Bezalel, the late-16th-century rabbi of Prague. There are many tales differing on how the golem was brought to life and afterward controlled. The word golem occurs once in the Bible in Psalm 139:16, which uses the word גלמי (galmi; my golem), meaning "my unshaped form", connoting the unfinished human being before God's eyes.

How is Opening Master different from free databases?

Despite getting our games from different sources, we dedicate a lot of time to eliminate duplicates. We also normalize the names of the players, which amounts to dozens or even hundreds of corrections a month. The free databases are often very low-quality and cluttered with lots of duplicates. There is no such thing as free lunch. We ask for a fair price starting at 39 EUR for one year (OM CORR). It is much cheaper than less quality commercial chess databases out there.
