International Master (1991); Grandmaster (1995).
Preamble
Oleg Anatolyevich Korneev has been one of the most active grandmasters in the world, with scarcely a rating period in the last twenty five years in which he hasn't participated in tournaments. (1) This has produced great fluctuations in his rating over the years. (2) Little is known at this stage of Korneev's career before 1991. He received his initial FIDE rating in 1988 when he reached 2280, and did not play another FIDE rated game until well into 1990 during which time his world ranking dropped by over 1000 places despite no movement in his rating, (3) which was most likely an artifice of the increasing number of players being rated by FIDE at that time, the number of active FIDE registered players doubling between 1988 and 1991. (4) The details of his career (below) therefore start in 1991, the year he gained his IM title.
Tournaments
<1991-1994> A solid 7/10 at least at the Krumbach Open 1991. (5) A score of 7/9 at the Hamburg Open in 1992 probably earned him equal second place, albeit certainly behind the likely winner, veteran Czech GM Vlastimil Jansa. Likewise, a score of 7/9 was probably sufficient for equal second behind Josef Klinger at the Werfen Open in 1992. (6) He was probably equal first at the Wichern Open in Hamburg in 1993, alongside the likes of Igor V Glek, Lubomir Ftacnik and Thomas Luther (7) and at the Werfen Open in August 1993 alongside Vladimir Burmakin, Igor Sergeyevich Lempert, Vladimir Lazarev and Josef Klinger. He was runner up to Peter Svidler at the first Linares Anibal Open in 1994 (8) and winner of the Foment Open in Spain in 1994. (9)
<1995> The massive Moscow Open of 1995 saw Korneev placing equal second behind Vladimir P Malaniuk and alongside ten other players. Korneev was very prolific in 1995 playing in numerous opens. Unfortunately, the exact results of many of these tournaments are very difficult to verify. What is known, however, is that in this period Korneev was a freshly minted grandmaster forcing his way into the top 100 and was in top form. On many occasions in 1995 he was within the leader board or troubling it in events such as the Badalona Open, the Terrassa Open, the Barbera Open, as well as the opens staged in Groningen, Zaragoza, Novgorod, Manresa, Berga and and Metz. (10) He was outright second at the category 10 Moscow Petrosian invitational round robin event, scoring 7.5/11, half a point behind the winner Mihail Saltaev (11) and equal first at the category 10 Minsk invitational.
<2004> Equal first at the 20th Cappelle la Grande (2004).
<2013> Equal first at the Chigorin Memorial (2013) and second at the 17th Voronezh Chess Festival 2013.
<2015> Winner of the 12th Avicenna Open 2015 in Iran.
Championships
<National> Korneev first played in the Russian Championship in 1995, albeit without troubling the leader board with 4/11.
<World> Korneev's sole participation in the World Championship cycle beyond the Zonals was at the World Cup (2005) where he defeated Evgenij Miroshnichenko in the first set of tiebreakers in the first round, but lost to Sergei Tiviakov in the Armageddon decider in the second round.
Team Events
<Olympiad> He represented Spain at the Chess Olympiad (2012)
<National Representation> He also represented Spain at the European Team Championship (2013).
<City Team> Played for the City of Moscow team that placed second at the first World Cities Chess Championship that was held in Jakarta 1997.
<Continental League> He played for the TPS Saransk club which placed 5th at the European Club Cup (2006).
<National Leagues> Korneev played with the Oberliga Nord in 1992 and 1993.
He first played with the Russian Premier League 1992. His participation in the Russian League has been intermittent since then, as well as frequently changing teams. In 1994 he played for Krylia Sovetov helping them to fourth place and winning individual gold for board one. In 1998, he played board four for the silver medal winning team Universitet Maykop. He played with TPS Saransk for the seasons 2006 and 2007, winning team silver in the former. His most recent participation in the Russian Premier League was in 2013 as first reserve for the Universitet Belorechensk which placed 9th.
Rating and Ranking
Korneev's first FIDE rating was 2280 in January 1988 (when 2200 was the rating floor for the official list). He first made it into the world's top 100 in July 1995, about the time he gained his grandmaster title, weighing in at =50th in the world, his rating being 2605 at that point. He has been in and out of the top 100 since that time, peaking in April 2006 when he was ranked #34 in the world and rated 2671, the highest rating he achieved. (x)
