Haha, already w/ the drama!
"5.48pm:
From the rather grainy, and completely soundless video on the Generalitat Valenciana site, we can see that the table is set.
Kasparov's just been out, briefly, swishing theatrically towards the table through a curtain at stage-right.
He sat on his seat, didn't seem happy with a black cushion that was on it, and promptly exited."
