Kramnik, as Black, blunders with 34. ... Qe3??—a classic example of chess blindness. Deep Fritz responds with 35. Qh7#.[1]

Amaurosis scacchistica (Latin for chess blindness) is the failure of a chess player, during a chess game, to make a normally obvious good move or see a normally obvious danger. The term was coined by Dr. Siegbert Tarrasch. Similar to chess blindness is the Kotov syndrome, in which a player, after a long period of calculation, suddenly makes a move he has not analyzed at all.
