Ruy Lopez. Its the best scoring for white last time I checked and I'm decent with it so I just might make it past move 10 lol.
If you had to face Carlsen.

Vienna. But only because I know it.
Or I might even have tried the King's Gambit – if I'm playing Carlsen, I'm going to lose anyway, so I might as well mix it up a little and go crazy.
If you had to face Carlsen with white pieces, what opening would you choose and why?
