If you want to save the world, stay at home and play chess. You have probably heard about the outbreak COVID-19 and how pandemic it is outside. We will not bother you with other frustrating facts but we can tell you one thing. Now you can save 50% by staying at home and playing chess. How?

Just a small update. We have completed semi-annual update of the OM Portal Chess Database with following updates - the files are so huge, that even Chessbase cannot work with them fully so we had to split it into two files. Hope it is ok. And the final number: 18 288 579 games.

This is probably THE biggest even in history of Opening Master. Ever since we started our collection back in 2004 we had dreamt of largest human chess collection. Not just computer generated games. But quality collection where chess players could benefit from the statistics of open positions and games. Where chess players would download in one since piece the entire human chess of the world.

A big update everyone was waiting for. We have been working hard for past half year and collected most of the online human games above 2000 ELO and inserted them into our OM PORTAL which is part of OM GOLEM. So all together we have come up with 29,390,692 human games without duplicates making it the largest human chess database on Earth.

For some time we have been analyzing our duplicates. We knew we had few, you always found some, we didn't how many we had but we knew there are these suckers who always pop up and destroy our image of duplicate free chess database. Well, no longer is the case. We announce duplicate free OTB chess database.
