Kramnik: ‘Some kind of black-out’

This is what Kramnik said about his blunder at the press conference: “It was not actually only about the last move. I was calculating this line very long in advance and… I don’t know… It’s actually very strange, some kind of black-out. Because I was feeling well, I was playing well before and… I think I was pretty much better…het opnieuw. Ik dacht: alles is in orde, en opnieuw en opnieuw en uiteindijk blunderde ik, mat in één. Het is werkelijk de eerste keer dat me dit overkomt en ik kan niet echt een verklaring bedenken want ik voelde me niet moe, ik voelde me goed. Ik denk dat ik goed aan het rekenen was. Het is gewoon heel vreemd. Ik kan het niet uitleggen.” and I calculated this line many many times, re-checking myself, and in all this Qe3 and Qxe4 I was calculating Ng6+, and okay, I already did it when I was playing …Qa7, I already calculated this line. After each move I was re-calculating it again. I was thinking it’s all fine, then again and again and finally I blundered it, mate in one. It’s really actually the first time it happens to me and I cannot really find any explanation because I was not feeling tired, I was feeling well. I think I was calculating well. It’s just very strange. I cannot explain.”
