Bruzon takes the great Ivanchuk out of mainstream theory quickly, but to no good end. White declines to go down a beaten path repeatedly until we reach the following position:
1.d4 Nf6 2.Nf3 e6 3.g3 d5 4.Bg2
A lot of known lines have been avoided to this point, but the game is at least now on the cusp of the Catalan. ChessBase classifies this position with the Torre, London, and Colle systems, but it's none of these. If you have a name for this, drop a comment. Nevertheless, the position has been reached often, and Black's next odd-looking move can be described as an anti-Catalan: 4...b5 Perhaps the kid Carlsen has shown the old master a thing or two. See the second game below.
