**Alexei Shirov** (born 4 July 1972 in Riga, Latvia) is a chess grandmaster. He has consistently ranked among the world's top players since the early 1990s, and reached a ranking as high as number four in 1998. Shirov is also a well-regarded chess author.

Career
------

Shirov became the World Champion (under 16) in 1988, and achieved the title of grandmaster in 1990. He is the winner of numerous international tournaments.

In 1998 Shirov's ranking rose to number four in the world. On the basis of his rating, he was invited to play a ten-game match against Vladimir Kramnik to select a challenger for World Champion Garry Kasparov. Shirov won the match with two wins, no losses and seven draws. However the plans for the Kasparov match fell through when funds could not be raised. When Kasparov played Kramnik for the world title in 2000, Shirov maintained that the match was invalid and he was the rightful challenger.

In 2000, Shirov reached the final of the FIDE World Chess Championship, losing to Viswanathan Anand.

In May/June 2007 he played in the Candidates Tournament of the FIDE World Chess Championship. He won his first round match against Michael Adams (+1-1=4, won in rapid playoff), but was eliminated when he lost his second round match to Levon Aronian (+0-1=5). In November/December 2007 Shirov played in the Chess World Cup. He lost in the final 2.5-1.5 to Gata Kamsky.

In May 2009, Alexei Shirov achieved the greatest triumph of his career by placing 1st in the high Category 21 M-Tel Masters 2009 tournament, a double round tournament held in Sofia, Bulgaria. He was undefeated, and scored 6.5/10—seven draws and three victories, two against Vassily Ivanchuk and the other against Magnus Carlsen in the final round. By this success he was given entry to the Grand Slam Chess Final 2009 in Bilbao where he met Levon Aronian, Sergey Karjakin (winner of Corus 2009), and Alexander Grischuk (winner of Linares 2009).

Personal life
-------------

In 1994 Shirov married, and later divorced, Verónica Alvarez, moved to Tarragona, and became a citizen of Spain. He married, then later divorced, Lithuanian IM/WGM Viktorija Čmilytė from 2001 to 2008. Although he still plays for Spain, he now lives in Latvia.

Playing style
-------------

Shirov is noted for his attacking style and for seeking complications, a tendency which has led to comparisons with fellow Latvian and former world champion, Mikhail Tal, under whom he studied in his youth.
