Grandmaster Koneru Humpy on Sunday outclassed Shen Yang of China with some brilliant manouvres in the first game of the quarterfinals and now needs just a draw in the second game to advance to the semifinals of the world women's chess championship, underway in Nalchik (Russia).
The highest rated player of the event, Humpy displayed some excellent attacking chess well compiled with fine positional ideas and Yang was outdone in all departments of the game.
The victory gave Humpy a crucial 1-0 lead in the two games mini-match of this knockout championship.
It was a Slav defense by Yang that spelt doom for her. Going for a not-so-popular variation the Chinese was in troubles right in to the early middle game when Humpy unleashed a king side attack.
Yang is considered to be a fine talent from the Chinese factory but Sunday turned out to be a bad day in office as she just could not produce any counter play with black pieces.
Humpy to her credit, played some positional moves before uncorking a piece sacrifice on the 21st and black's position collapsed in quick time thereafter.
Yang lost her extra material a few moves later but her king's position had become vulnerable. On the 27th move, Humpy came up with another knight sacrifice and it was curtains for the Chinese four moves later.
In the other games of the quarterfinals former world champion Antoaneta Stefanova suffered a major setback when she was beaten by Pia Cramling of Sweden.
Stefanova also faced a Slav defense but failed to produce the magic of Humpy with white pieces.
