Opening explorer user guide

This official support article will explain what everything means: https://support.chess.com/article/355-how-do-i-use-the-game-explorer

Be careful taking the opening explorer results to heart; it is important to have caution when looking at the data

So, I recommend checking out this blog post which has some straight-to-the-point tips on reading and interpreting the opening explorer: https://www.chess.com/blog/payetteforward/how-to-use-the-opening-explorer-on-chess-com-the-right-way

Here's a sample from the blog post I think you will find immediately useful:

• As long as a move has been played a few hundred times or more, it's an option.
• If there's a move that's been played 10,000 times and then others that have been played just a few hundred times, there's a clear choice about which move is the best.
• People focus way too much on the statistics of a move that scores better, and then they get overwhelmed because there are a lot of options, all of which have been played hundreds of times. What should they do? Forget about all that!
• As long as a move has been played a few hundred times and it's within a percentage of a decent score, then it's an option.
