Blitz Jewel

The Norway Super tournament started with the traditional blitz tournament which defines the players who will have an extra white color during the main event. This year's edition was convincingly won by Maxime Vachier-Lagrave straight from the plane from Leon (Spain). As usual, there was a lot of drama suspens, and beautiful chess. Check this attack for example:
