I believe chess is solved. The Ruy Lopez, Berlin Defense and Nimzo Indian Defense are the best opening moves.
Clearly chess is not solved, because if it was, you would know whether 1.e4 or 1.d4 is stronger, and clearly you don't if you have to provide a response to each as "best play" by both sides. Only way chess is solved is if you know all the best moves for both White and Black.
