Whether you are a beginner with hunger to play online chess, or professionals with GM rankings, you need to feed yourself with quality chess database.

And the Opening Master Portal chess database offer exactly the service needed. With more than 1 million games you get best possible preparation for your game.

One good advise from Opening Master. Do not use engine and chess database only. Use your brains. Most of todays chess website 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 advise. Use it wisely, don't just copy paste the result of the analysis (if you ever have time between the moves). Think and learn.
