FIDE is now a political organization. And being a political organization, it, of course, means that people in FIDE have some other interests – that is, to sit in their positions for the next hundred years.

Sometimes you can come up with some amazing solution but most of the time you just end up looping: you consider a move, you reject it, then you’re desperate, you come back to the move, you don’t remember why you rejected it, you have to make a move so you make it – then your opponent replies and you remember why you rejected it. The longest wait I ever did between moves was one hour and five minutes – and the move was horrible.
