A little move with deadly consequences. Part two.
In the first part of this article (http://www.chess.com/article/view/a-little-move-with-deadly-consequences) we analyzed games where one side moved his King to prepare pushing the 'g' pawn to launch a Kingside attack. Today we'll discuss other benefits of shifting your King.
One of the oldest examples happened in the next classical game.
A different case of a 'weird' King move can be seen in the next famous game.
This is one of the most complicated games in chess history in my opinion. Kasparov himself devotes 22 pages to analysis of this game in his book about the World Championship match vs. Karpov. There is no point in repeating here the ocean of his variations (if you are interested I strongly recommend to get the book where he analyzes this game). Let me just quote his explanation of the mysterious 31.Kh2!! move in the middle of the attack. Kasparov says: "This is the last prophylaxis. It is necessary to move the King out of the weak first rank. After that White is ready to start his attack."
He doesn't give any concrete variation where it is clear that 31.Kh2!! was really necessary. But for any experienced chess player it is pretty obvious that an opportunity to concentrate on your attack without being distracted by your opponent's pesky checks along the first rank is the luxury that fully justifies spending a tempo to move the King.
This outstanding game of a very young Artur Yusupov didn't get into the databases, so we should thank his coach and very famous chess trainer IM Mark Dvoretsky for preserving this game.
