What Is Chess.com's Game Database?

Chess.com's database lets you see all the games ever played on the site. Not only that, but it also groups that information to make it easier for you to see how many games have reached each specific variation. 

Imagine you just started playing chess and your friend beat you in four moves with the Scholar's Mate. You won't feel so bad about it when you learn that other players on Chess.com fell for the same trick more than 14 million times before you!

The database also shows the percentages of games that ended in a White win, a Black win, or a draw. So you'll feel even better when you realize that 17% of players who went for the cheapo with White got justice delivered to them and lost the game.

You'll notice that, as you make moves, the database will keep showing what has been played and how many times. If you want to see how Black pulled off those miraculous comeback wins after blundering mate in one, you can keep playing moves, and the database will show you. 

How To Use It To Improve Your Opening Prep

Chess.com's database lets you check the lines other players are choosing against specific openings. With this tool, you can see exactly how players in each rating range are challenging certain openings.

Let's say you value winning above all else and are absolutely shameless. By looking at our database, you'll quickly realize that the Englund Gambit might be a good choice for your unscrupulous dreams when you're below 1600. But approaching 2000, you'll start paying your dues.

You can also resist temptation and use our database for good. For example, let's say you're interested in learning the Caro-Kann as Black. Looking at the numbers, you'll notice that most players on Chess.com play either the Advance Variation (49%) or the Exchange Variation (23%). With this data, you know that you should spend most of your time studying these two lines.

You can then check out the options that score well against those moves. You can also analyze the resulting positions with an engine to see the strongest moves in those lines. In the Caro-Kann example, you'll see that 3...c5 can be a nice surprise weapon against the Advance Variation, with only 30% of games reaching that position and Black winning in 50% of them.

Now, let's say you're around 1200 and you've watched a GothamChess video about the Vienna Gambit. However, you can't remember all the variations Levy mentioned. You can check out what people at your level are playing against that opening with our database. You can then focus on learning those specific variations, so you'll be prepared for most of the games you play.

At one point in his video, Levy mentions 5...Nxc3, 5...Nc6, and 5...f5. Looking at our database, you'll see that you could focus mostly on 5...Nxc3, since Black plays it 63% of the time. In his video, Levy spends quite some time talking about 5...f5, but that only happens in 11% of games at your level—so maybe you can skip that line and rely solely on opening principles to guide you!
