barely playable. Thanks to the efforts of Topalov and some other top players
it has come back to the world chess scene. Ivanchuk is a very universal player

position. Mamedyarov, on his part, is well informed - the rook on the 3rd rank
is cleverly prepared for various types of activity.} (14. Nc4 Ne5 15. Ne3 f5 (

White's N for his Bc8, after it comes to c4, and prepare the b5 thrust (a6,

Nh5,f5 or h6,g5. White's chances as usually in the Benoni lie in the center
