2005

In Smartfish Chess Masters at the Drammen chess festival 2004-05 (Norway) Carlsen defeated Alexei Shirov, ranked number 13 in the world. In June 2005 in the Ciudad de Leon rapid chess tournament Carlsen played a four-game semi-final against Viswanathan Anand, who was ranked 2nd in the world at the time. Magnus lost 3-1. Carlsen was invited to the tournament as the most promising young chess player in 2005. In the 2005 Norwegian Chess Championship, Carlsen again finished in a shared first place, this time with his mentor Simen Agdestein. A playoff between them was arranged between 7 November and 10 November. This time Carlsen had the better tiebreaks, but the rule giving the player with better tiebreaks scores the title in the event of a 1-1 draw had been revoked previously. The match was closely fought, Agdestein won the first game, Carlsen won the second, so the match went into a phase of two and two rapid games until there was a winner. Carlsen won the first rapid game, Agdestein the second. Then followed a series of three draws until Agdestein won the championship title with a victory in the sixth rapid game. At the end of 2005 he participated at the World Chess Cup in Khanty-Mansiysk, Russia. In the knock-out tournament, Carlsen upset the 44th-ranked Georgian Zurab Azmaiparashvili in round one, winning 2–0 at rapid chess after a 1–1 tie in the normal length games, and proceeded to beat Tajik Farrukh Amonatov and Bulgarian Ivan Cheparinov (also after rapid chess) to reach the round of 16. There he lost 1½-2½ to Evgeny Bareev, which prevented him from finishing in the top eight. He then won against Joel Lautier 1½-½ and Vladimir Malakhov 3½-2½ securing him at least a tenth place and therefore a spot in the Candidate Matches. Carlsen became the youngest player to be an official World Championship Candidate. In October 2005 he took first place at the Arnold Eikrem Memorial in Gausdal with 8 out of 9 points and a performance rating of 2792 at the age of 14.
