You can get a general idea about the opening that way, but you really need a bit more guidance. There are approximately 40 videos on the Ruy Lopez on chess.com. Here's a good way to start...

When you have watched it a few times, then you can make use of the Explorer and it will make a lot more sense to you. Sam Shankland has a 4 video course on starting the Ruy Lopez that might be the next step. Good luck!
So I'm trying to learn how to use the Roy Lopez opening. I've gone to the opening software here and found that opening. I play through the first three moves or so that seem to be book opening, but then it gives a list of possible moves with the most favorite at the top.
Should I keep clicking on the most used lines and follow that as the best lines to take? Is there something that I'm missing about using this opening software?
Any help would be appreciated.
