We are in India! Finally. Happy to announce OpeningMaster registered .in domain and will start to offer chess databases for its Indian chess players. Have you ever asked yourself what is the biggest chess database? How many Indian chess players are registered? Who are we partnering with?

Amongst Indian chess players there are 74 Grandmasters (GM), 125 International Masters (IM), 18 Woman Grandmasters (WGM including some who also hold the higher IM title), 42 Woman International Masters (WIM), and a total of 33,028 rated players, as of January 2021 according to FIDE, the International Chess Federation.


We would like to stop by with "little" Praggu. The chess prodigy GM Praggnanandhaa was only 12 when he earned his GM as 2nd youngest Grandmaster. (only few weeks after Sergej Karjakin). And there are three other GMs younger than 14. Reason? Indian education system invests into the chess. Chess is part of the school syllabus. Chess is taught at elementary or middle schools. We don't need to discuss why.

The biggest chess database

What is the biggest chess database? How do you define it? First of all, we do not mind somebody has bigger, let them have it. We care about the quality and officially recorded human chess games. We split the large chunk into two pieces and still working on it. The OM OTB with more than 9,3 million chess games is intended for over-the-board players, FIDE registered chess games. The size is already large enough to say we got it all. The other smaller is OM CORR with more than 2 million correspondence chess games. The OM GOLEM is basically all together plus our large piece of chess portal games called OM PORTAL. 30 million games should be really enough for your statistics.

The correspondence chess games played on various correspondence chess portals such as ICCF, FICGS, Lechenicher SchachServer (LSS) is a different animal. The games usually go much deeper in the analysis, there are much less human mistakes but you are risking the help is by the machine / engine. So somewhere back in 2011 we decided to split these two ever since kept them separated. However, both databases are created by human chess players. We do not support engine vs. engine games.

What is the intention of a chess database?

1. Collect and present the chess history

2. Analysis and statistics of a position

3. Learning the openings.

Collection and history in one chess database

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 990 Rupees for one year (OM CORR) and 1990 Rupees for OM OTB. It is much cheaper than less quality commercial chess databases out there.

Recently we found a great comparison published on website by one Spanish chess player.
