Dark Archangel

This is how black should play against Ruy Ropez, how to handle every line according to Fabiano Caruana. A course you can find via "Chessable".

This opening was using a few days ago in the Qatar Masters 2023, where GM Murali Karthikeyan (2611) beat GM Magnus Carlsen (2839)

It's very rare to see Magnus beaten, and even more rare to see him beaten while playing with the white pieces.
