I changed the text to refer to a king side pawn bind that may be useful in an endgame Shades of Han Kmoch s quartgrip in Pawn Power in Chess I think this may capture what Karpov and Beliavsky said better than time wasting See what you think Note that this passage is now in some tension with the sentence in the next paragraph about how Black usually I changed this to often does well if an endgame is reached Maybe that sentence should be changed some more Also is it accurate to suggest that Black often leaves his king in the center I m not sure whether that s accurate It might be I m not a great authority on this opening I think there was a game where Beliavsky beat Larsen like a drum when his king stayed in the center too long 9 July 2005 01 44 UTC
