Ruy Lopez - find the right move

To celebrate the team's first anniversary, I propose this game to which everyone can freely participate. It is a matter of retracing a game between two GMs, putting on the role of white in a classic Spanish, with a main line approach.

Starting from a predefined position, a new move will be published every day, following the game in question step-by-step.

Each competitor will have 24 hours of time (subject to my possible delays), to signal what is his best move. It is not necessary to attach analyzes or other information, it is sufficient to indicate one's move.

All proposals will be evaluated and a score assigned to each.

Free use of the database and the use of engines is absolutely prohibited. Also because all the moves are already scanned by me with an engine, so what is not very human I immediately catch.

This is the starting position, playing white

To you the move: what do you play with white?
