Kasparov's handicap (Score 1)

I recently read an article that suspects that Kasparov has a special handycap at the moment: His mother, who normally watches every game he plays seems to be very ill and is reported to leave matches early recently, guided by a nurse. Unfortunately, I have no link available (the article appeared in last week's issue of Der Spiegel, a german news maganzine). They say that Kasparov plays really uninspired recently and they believe it may be due to that. So maybe when she gets better, there will be a rematch.
