'The best game of the last 20 years'...

by ChessBase

I like it! | 0 Comments

1/16/2010 – ... Jan Timman wrote about this encounter between two absolute top grandmasters of the 70s and 80s. Here Black played 21...Bb5 and later succumbed in a remarkable attack. How would you assess the position after 21...Nxc7 instead? A) The second player maintains his plus pawn without risk; B) White gets the advantage; C) the result is a draw by perpetual check. The solution is here, but first ponder over it with a larger version of the diagram.
