The world champion lost 10 speed games in St Louis and has only two days to recover before the start of the Sinquefield Cup
Magnus Carlsen’s form collapsed in spectacular
fashion this week just as Norway’s world champion, 28, seemed invincible after a run of eight consecutive tournament victories.
The prestigious $325,000 Sinquefield Cup at Saint Louis, named after the billionaire who has transformed US chess and made his home city a global centre for major events, starts on Saturday, with Carlsen the clear favourite.
