Vietnam's best chess player Le Quang Liem dramatically beat the world No.4 Russian Alexander Grischuk in the third round of the Chess World Cup 2013 in Tromso, Norway on Monday .
On Friday, Liem, standing 42nd in the World Chess Federation (FIDE) rankings with an elo rating of 2702, beat Grischuk, elo 2785, in the first leg of the standard chess game after 44 moves.
The next day, Grischuk leveled the score by beating Liem after 154 moves in 6.5 hours, one of the longest games in the chess history. At one time in the game, Liem looked equal and was about to earn a draw and take an aggregate win but he made some mistakes and lost the second leg of the third round game. And the two players had to play a rapid chess tie-break game to decide the winner.
Before the rapid chess tie-break game, the 22-year-old Liem was considered to be inferior to the 29-year-old Russian not only because of FIDE rankings but also because Grischuk has been a two-time blitz chess champion.
However, Liem started the first leg of the rapid chess on Sunday in a confident mood. He launched attacks from the beginning even though he was playing black pieces. It was a bit surprising for Grischuk, who lost the advantage of playing white and lost the first leg after 68 moves.
Grischuk tried even harder in the second leg in an attempt to level the score again, but Liem had the advantage of playing the white pieces. Both players attacked and fought to a tie after 102 moves. The second leg draw and the first leg win for Liem earned him an aggregate 2.5-1.5 win over Grischuk in the third round.
Liem advanced to the third round of the 2011 World Cup and now he has entered the fourth round. He is also the only Asian player to be among the last 16 players at the event this year. Other Asian strong players from Asian powers like China and India have bowed out.
In the fourth round, Liem will clash with the 15th-ranked Russian Peter Svidler, elo 2746. The 36-year-old Svidler is the reigning champ and a six-time champion in Russia.
