OpeningMaster.com is a privately owned enterprise and as all business it also started as a hobby. A hobby to play chess. The authors of the OpeningMaster database as well as other smaller unique databases which have been released under brand OM has been involved in chess for more than 30 years and are internationally recognized (ICCF) players. The main head of the project is Alexander Horvath, Senior International Master, ICCF (ELO 2487, 1. GM Norm), member of Slovak National Team who actively plays chess on various national and international correspondence tournaments.

Some time ago (around 5-6 years), when chess databases were already around, the first OM idea was born. To create one largest collection of only quality games which had been played between humans and summarize it in a readable format (Database) which could be used with best database programs (e.g ChessBase). And why to build another database when world already knows few, one may ask? Becasue the data presented those days (as well as nowadays) are in bad quality and can actually hurt the player rather than helping him/her. Here are few examples why Opening Master was created : 

• DO NOT HAVE multiple data / same games presented twice - duplication issue
• DO NOT HAVE short games (less than 8 moves) inserted in
• DO NOT HAVE computer games inserted in
• DO NOT HAVE games which were played prior 1900 as we consider them as 'too romantic'
• DO NOT HAVE games without body (as they don't bring any analysis value add)

all of these were swept away by Opening Master. Compared to other commercial products on the market,  we can proudly present OM doesn't market the quantity but rather quality. (by the way in quantity it has also No. 1 position worldwide)

If you have any questions regarding the entire process, how it works, what kind of data is in, please refer to tutorial pages or individual product reviews.
