Khanty Mansiysk: Grandmaster David Navara of Czech Republic continued with his dream run and scored a comprehensive victory over Yaroslav Zherebukh of Ukraine in the first game of the pre-quarterfinals of the World Chess Cup.
Navara, who was stretched till the 10-minutes tie-breaker in the previous round, did not show any sign of fatigue and played a fine counter-attacking game in the Sicilian Scheveningen.
The fact that the Czech maestro played black now makes the task even easier for him as he is just a draw away to secure his place in the last eight.
Chinese Grandmaster Xiangzhi Bu, who was lucky to find himself on the winner`s seat against Indian GM Abhijeet Gupta in the previous round, did well to hold second seed Vassily Ivanchuk in a keenly contested game.
Vladimir Potkin of Russia defeated compatriot Alexander Grischuk from what seemed like a heading-for-draw rook and pawns endgame. Running short of time, Grischuk made the ill-fated 40th move that swung the tide decisively in favour of Potkin.
Navara was the star of the day given the simplicity with which he won. Zherebukh, till the start of this game, could do no-wrong as he had to his credit victories against two top ranked players Shakhriyar Mamedyarov of Azerbaijan and compatriot Pavel Eljanov knocking them both out of the World Cup.
