World junior champion Pendyala Harikrishna moved into the semi-finals in the Lausanne Young Masters International Chess tournament with a hard-fought draw with Magnus Carlsen of Norway in the second game of the two-game mini match.

Having won the first game displaying great endgame acumen, Harikrishna knew that a draw was enough for him to proceed further in the tournament and the Indian achieved precisely that after 66 moves to notch a 1.5-0.5 victory over Carlsen.

In the semi-finals, Harikrishna will have to tackle top seed and former Ukrainian champion Andrei Volokitin in this unique event that has top young players of the world participating.

The tournament is being played on the knock-out format with the exception that the losers will fight it out for the remaining place.

Interestingly, fourth seed Harikrishna was the only favourite to concede a half point to Carlsen as the remaining three knocked out their opponents by 2-0 margins.

According to chess pundits, this happened because the Indian played in round one against the toughest opponent, who is often touted as the future World champion.

In the remaining three matches of this eight-player event, Volokitin, United States champion Hikaru Nakamura and former World junior champion Shakhriyar Mamedyarov of Azerbaijan ended winners for the second day running against Elisabeth Paehtz of Germany [Images], Nana Dzagnidze of Georgia and Maxi me Vachier Lagrave of France [Images] respectively.

The other semi-final will be played between Nakamura and Mamedyarov.

For Harikrishna, things did not come easy as he might have wished against Carlsen, who went for the blood right from the word go.

It was a Ruy Lopez opening in which the Indian played black and looked in all sorts of trouble after Carlsen unleashed an optically brilliant piece sacrifice to rip a part black's Kingside.

Harikrishna, however, put up some brilliant resistance and when the dust subsided he was an exchange down with enough hopes for a draw. Carlsen exchanged the queens on the 45^th move not judging the endgame well enough and Harikrishna, with his perfect defense thereafter forced his opponent to split the point.

It turned out to be a better day yet again for Volokitin as he stormed past the challenge of Paehtz amidst tactical complexities. The opening was a Sicilian Paulsen in which the Ukrainian played black and spotted a hole in the calculations of Paehtz to win a pawn by force in the middle game.

So on after it was a rook and opposite colour endgame on board and the technique of Volokitin did not desert him. The game lasted 55 moves.

Nakamura was quicker in scoring over Dzagnidze, who blundered away a seemingly equal endgame in the Grunfeld defense. Playing black, Nakamura won an exchange by force in the queenless middle game and the rest was child's play.

Mamedyarov also had it easy against Vachier-Lagrave in another Ruy Lopez of the day. Playing white, the French went haywire in the endgame where he first lost a pawn and later found his king under firing line. It took 44 moves for Mamedyarov to romp home.
