Caruana's famous home preparation strikes again. This is something I can comment on with knowledge of the facts: in 2010, at the Olympiad, I lost a famous game in which the young Caruana had prepared a beautiful queen sacrifice in his laboratory. 8... c5d4  9. d2c4  9... b8c6 [%c_effect c6;square;c6;type;Inaccuracy;persistent;true] 10. f1d1 A new and natural move. 10... d8e7 [%c_effect e7;square;e7;type;Mistake;persistent;true] After this move, White regains the pawn in an ideal situation. 11. a2a3  11... b4d6  12. f3d4  12... c6d4  13. d1d4 This is the typical nightmare position for Black in the Catalan Opening. The g2-bishop is mortal. In the hands of an elite chess player, it's no exaggeration to say that Black is already strategically lost. 13... d6c7  14. d4d1 A good and safe move: the rook returns and the bishop is ready to be developed on d2.

Robson tries some desperate resistance; after all, this is a rapid game, and a loss means elimination. 25... e6e5
