While researching material for the article on the best games of GM Artur Yusupov (mona-lisa-of-gm-artur-jussupow ), I found the next little known gem.
The position in the following diagram is typical for the King's Indian pawn structure. Usually it implies a long positional battle where White tries to utilize his spatial advantage. But GM Yusupov found a new approach and here he starts a vicious and unexpected attack against the Black King. Can you find a little move that helped him to launch his attack?
(Just like in most of my articles I give you a chance to test your attacking skills, so the games are given as a Quiz. Please remember that you can always replay the whole game from the first move if you click "Solution" and then "Move list".)
That was a very nice game, but the next one is even more impressive in my opinion. Unlike the previous game, Black doesn't have a spatial advantage. In fact it is just opposite: he is squeezed to the last three ranks (which is quite typical for this system called the 'hedgehog'). And yet, very soon he will have a very dangerous attack against the White King. Can you guess how GM Yusupov managed to pull it off?
Was it difficult for Yusupov to find such a brilliant attacking concept? It was not necessary since he knew the next classical game for sure.
Now my dear readers, when you know one of the most incredible ideas of Bobby Fischer, I hope it will be easy to guess the moves of the next game.
I don't want you to have the wrong impression that just by playing Kh8 (or Kh1) followed by the 'g' pawn push and doubling Rooks on the 'g' file you can automatically win the game. The position remains very complicated and one wrong move can lead to a catastrophe, as the next game (which, by the way, was the main sensation of the 2006 Chess Olympiad) demonstrates.
Conclusion: Fischer's brilliant idea turns a quiet position into a tactical mess and offers very good chances to attack the opponent's King.
