Quotes of the Day
Never felt more like singin’ the blues, cos I never thought that I’d ever lose…
Vladimir Kramnik 2017
If I’m thinking for more than 20 minutes about one move, it’s usually a waste. 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.
