The OM PORTAL is best used for players who are hooked online to the biggest online chess web sites. Our collection with more than 18,7 million human chess games is the biggest ever. Until 2017 we kept all Portal games in. Starting the year 2018 we decided to upgrade the quality and publish only games with higher ELO than 2000. The number of games reduced dramatically to only 7 million games but we think it's the quality you are looking for not the quantity.

Which Chess Portals to play online chess

The chess portals such as,,, or FICS - offer a free professional environment for all chess lovers. There are many advantages of each website, some like has for example a Facebook app that you can use to play. You can also play with a time limit of days/weeks and this is very useful if you rarely can find the time to sit down and have a serious game straight. The ChessCube has one of the nicest user interfaces, although it cannot be used with iPhone or iPads since it uses flash. Each of these chess websites has its own playing history and players. You build your ELO by winning games and tournaments. Whether you are a beginner with a hunger to play online chess or with professionals with GM rankings, you need to feed yourself with a quality chess database. Prepare for the opponents with nicknames from around the world. All of the chess sites offer friendly communities, great tournaments with commented games and videos from professionals. And the Opening Master Portal chess database offers exactly the service needed. With more than 18 million games you get the best possible preparation for your game.

One good piece of advice from the Opening Master. Do not use engine and chess database only. Use your brains. Most of today's chess websites can identify whether you are "human" or android. Using a computer to calculate moves dynamically is against the rules on these web sites. Looking up moves from static sources is within the rules. It doesn't matter if the static sources are accessed using a computer. So our advice. Use it wisely, don't just copy-paste the result of the analysis (if you ever have time between the moves). Think and learn.

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 39 EUR for one year. It is much cheaper than less quality commercial chess databases out there.
