The starting out position for the Ruy Lopez is set up so that you will not be able to avoid the main lines. The reason is that we believe most learning can be derived there.
There have been a few other questions about the tournament so let me answer some of them here. This event is not national rated and there are no placings apart from the Champion simply because we do not want that to be a roadblock to experimentation and learning. Nobody will know how you did in the Tournament apart from the Champion so you are free to try out new ideas.
As I have said before you need to play some tournaments just to learn new things so that you can win in the tournaments that count. And there is a lot of learning from the Ruy Lopez. Look at it this way. You get to play 10 rounds of one opening in a strong field.
At the end of that 10 rounds you have stress tested that opening. This is also good for players who are normally play d4. Use this to test your open game strength. This is important for your overall development.
I have also shared my competitor analysis with Jax Tham and Sumant. Both have said they have learned something from it. I will also share this at the Thematic.
All my best in your chess development.
