A classic example of prophylaxis. With his next moves White restricts the black minor pieces, guaranteeing to keep the bishop pair as well.

Stopping ...Bc5 and fixing the black pawn structure on the queenside. White can put a lot of pressure on in the future with an eventual a4.

Once again, we ask ourselves, what does Black want to do?

The knight on g7 is completely dead.

The difference in activity between the minor pieces is evident.

Another good prophylactic move, stopping the trick on b4. White has a decisive advantage.
