At the current Norway tournament, Nils Grandelius tried to do a 'Marshall', by playing a Nimzowitsch Sicilian against Magnus Carlsen. Despite having been caught unaware, Carlsen figured that sensible moves should suffice, although a piece sacrifice on move 10 stretches that definition a little. However Grandelius overplayed his hand a few moves later, and was forced to return a rook. After that it was smooth sailing for the World Champion.
Carlsen,M (2851) - Grandelius,N (2649) [B29]
