Cap D'Agde: Radjabov - Karjakin

The final in Cap D'Agde had an exciting finish when 16 year old Karjakin faced 19 year old Radjabov in two rapid games. The first game ended in a draw when Karjakin was unable to break through Radjabov's Sveshnikov. In the second game Radjabov treated Karjakin to a poisoned pawn Najdorf. I was following the game on Playchess and at first thought that Radjabov had been lucky as the engines indicated that black was better. Closer analysis revealed however that black was fighting for a draw at best.
