[what is this?]

Born in Lima, Deysi Cori is a WGM with at least six IM norms and an entitlement to an automatic grant of an IM title because of her qualification to the 2013 World Cup. She is the older sister of GM Jorge Cori.


Cori came 2nd in the Women's Continental Championships in September 2009 and then won the World U16 (Girls) championship held in Antalya, Turkey in November 2009 ahead of Meri Arabidze. In October 2010, she was runner up on count back to Narmin Kazimova in the World Girls U18 Championship, both women scoring 9/11 and in November 2010, she scored 5.5/9 in the Pan American Continental Championships, her only loss being to her brother, Jorge. In December 2010, she was eliminated from the first round of the Women's World Chess Championship (2010) by IM Mariya Muzychuk but in June 2011 she came =1st with 7/9 in the Pan-American Absolute Championship (U20) alongside Argentinian FM Leandro Krysa, and =1st with 8.5/11 in the Women's Continental Championship IN Ecuador alongside Cuban WGM Oleiny Linares Napoles . In July 2011 she made a clean sweep of the field with 8/8 at the Pan American Youth (U​​-18 Women) Tournament. After a modest performance at the World Junior Championship (Girls) (2010), where she scored 8.5/13 to place =7th, she returned the following year to record her greatest triumph so far, to win the World Junior Championships (Girls) (2011) outright with 11/13 (+9 -0 =4), coming from behind with a win in the last round and winning an IM norm. Upon Cori’s return to Lima, Peruvian President Humala honored her at a nationally televised award ceremony held at the Golden Hall of the Government Palace by awarding her the medal of honor for sporting achievement, and giving her a 25,000-sol (US$9,100) cash prize. (1) In November 2011, she was the only female in the field that contested the open U18 World Championships. She lost the last round to place =8th, scoring 6/9 for a TPR of 2440. Had she drawn the game, she would have been =5th, and a win would have placed her =2nd. She failed to defend her Junior (Girls) crown by losing the last two rounds to place 6th, a point behind the coleaders of the World Junior Championship (Girls) (2012). She qualified for the FIDE Knock-out Women's World Championship (2012), but lost in the first round to the eventual winner, and 2012 Women's World Champion, Ukrainian IM Anna Ushenina.

In May 2013, she placed 6th in the American Continental Championship and consequently qualified for the World Cup (2013), the only woman to do so via a qualifying tournament apart from Judit Polgar her opponent in the first round was US super-GM Hikaru Nakamura, to whom she lost and therefore exited the event. In March 2014, she competed in the 7th Women's Championship of the Continental Americas as the rating favorite, but scored only 6/9 to place =4th. In October 2014, she scored 7.5/11 in the American Continental Championship restoring the 14 Elo points lost from her poor showing at the Hostafrancs International Open in August. Cori competed in the FIDE Women's World Chess Championship (2015) but was eliminated in the first round by Tingjie Lei. In May 2015, she scored a rating-neutral 7/11 at the American Continental Championship.

In 2015, she qualified as a reserve from Zonal 2.4 to play in the World Cup (2015) after her brother Jorge, who had previously qualified, withdrew to contest the World Junior Championship. In the first round of the Cup, she was defeated by Vladimir Kramnik and therefore exited the event.


Cori played board 1 for Peru at the Chess Olympiad (Women) (2012) in Istanbul, scoring 7.5/11, and again at the Chess Olympiad (Women) (2014), this time scoring 9.5/11, although this was insufficient for a medal.


Cori came a strong =11th-33rd (26th place on count back) with a 2562 performance in a field of 640 players in the Cappelle la Grande (2010), earning her another IM norm and just short of a GM norm. In August 2010, Cori played in the 12th International Open at Barcelona, scoring 6.5/10 and defeating tournament winner Tomasz Markowski. In April 2011, she scored 5/9 in the American Continental Tournament in Mexico and in August she won the World Girls Junior Championship (see above). She played top board for Peru at the Chess Olympiad (Women) (2010), scoring 8/11 with a 2424 performance rating. In September 2011, she placed outright first in the 2nd Magistral Diez Reinas held in Buenos Aires, scoring 7.5/9, and in November 2011, she scored 6/9 in the 2nd Latin American Cup. Early 2012 has seen a slight downturn in her fortunes with below par performances in the Moscow Open (4/9) and in the Aeroflot Open B (4/9), slicing 29 points from her rating, but a strong 6/9 at the XX Open Ciutat de Montcada in July 2012 and an equally strong 7/10 at the 22nd International Open in Benasque restored the balance while a further result of 7/10 in the powerful Simon Bolivar Tournament in Venezuela in September and October boosted her rating stocks significantly, and also won her another (her 2nd) IM norm, again narrowly missing a GM norm. Like her brother, she scored 6/9 in the Chigorin Memorial (2012), adding a few points to her rating card. However, she started 2013 with a relatively poor 5/9 (+4 =2 -3) at the Copa IPD 2013 "Categoria Especial" in Peru; one of her three losses was to the tournament winner, her brother, Jorge. She gained a measure of revenge by beating Jorge in the 1st Magistral IPD in Lima in February 2013, where she scored at least her 6th IM norm, and picking up 13 rating points for her 5.5/9. A few days later at the 2nd Magistral IPD, she scored a less auspicious 5/10, losing 6 rating points, but still managed to notch a win against Chilean GM Rodrigo Rafael Vasquez Schroeder. In May-June 2013, she came =1st (along with her brother Jorge and others) at the 1st Arequipa International in Peru, scoring 5.5/7.

In June 2014, Cori played in the XXII International Open in Montcada i Reixac, in Spain, scoring a respectable 5.5/9, a point and a half behind the joint winners Ni Hua and Yaroslav Zherebukh. In the following month (July 2014), she scored 6/9 at the 35th International Open at Benasque in Spain. Immediately afterwards, she participated in the 16th International Sant Marti Open in Barcelona where she scored 5/9. In August she scored a relatively poor 6/10 at the International Open in Hostafrancs in Spain.

In December 2014, Cori placed 2nd in the Bolivarian Cup that was held in Lima. She finished 2014 and started 2015 with =2nd at the 5th Latin American Cup held in Ecuador over the New Year period, scoring 7/9, one point behind the winner Lazaro Bruzon Batista this event recorded yet another IM norm and she only missed a GM norm as the first two opponents that she defeated were rated too low for her results to be considered, due to the fact that the average rating of all her opponents was slightly below the floor considered under the FIDE regulations for GM norms. Since then her tournament scores have been mediocre, including 5.5/9 at the Sitges International Open in July and 6/9 at Badalona International Open in August. She won the 2016 Women's Continental championship(3) at Mexico in November of 2016 after securing clear 1st in the 8th round with a round to spare.


Cori's highest rating to date is 2444, reached in February 2015. Her highest ranking among women was #42 in August 2013 when she was rated 2434, and again in February 2015 (2444).

She has at least 7 IM norms and an automatic qualification as an IM through her qualification to the 2013 World Cup, and the requisite rating for an IM, but it is unclear why she has not yet been awarded the title as she appears to have more than fulfilled all the prerequisites since 2010. (2)

  HeMateMe: Peru, next world chess power! Me gusta!
Aug-20-11  wordfunph: "Every time I played I thought about Peru; because when I play, my country plays. I feel really proud to be a Peruvian. Now, my objective is to train for next year because my main goal is to become the world supreme champion."

- Deysi Cori

Aug-21-11  Jim Bartle: Tremendous reception, hundreds of people, in the Lima airport when she returned. Then she was whisked off to the Presidential palace.
Premium Chessgames Member
  WannaBe: Helloooooooo future ex-ex-ex-ex-ex wife, by the way, I enjoy walking on the beach, (in Alaska, early November, or late March, where I can hunt, I like to play chess, Oh, you too, what a coincidence. BBQ'ed caribou, or moose, if you prefer. Or what ever else you like, I like it too!! =)

Who are the ther 11 that is ranked ahead of you, I will 'take care' of them!! (I'll send <technical draw>, and he'll beg them for 20$ to death!)

If the list includes <Jim Bartle> I'll do it for freeeeeeee!! =)

Nov-27-11  twinlark: Congratulations to WGM Deysi Cori for both competing in the "Boys" U18 World Championship, placing as well as she did, and scoring above her rating.
Nov-27-11  asianwarrior: A very beautiful lady.
May-28-13  Caissanist: Regarding Deysi's IM title--the Peruvian chess federation is known for having problems getting title applications approved; Emilio Cordova had to wait a year, and Christian Cruz several years, to receive their GM titles after earning them. She'll no doubt get her IM title eventually, after whatever got messed up is fixed.
Jul-30-13  waustad: The only IM norm mentioned on the FIDE page is one from the Chigorin Memorial. I am aware that there are many norms out there that are not shown on their pages though:
Aug-10-13  torrefan: Nakamura's beautiful first round opponent at the 2013 world cup. I hope he loses concentration.
Aug-11-13  SirRuthless: Apparently he was not ensnared by her beauty.
Sep-20-13  John Abraham: Deysi is in 2nd place in the World Junior Championship with 5.5/7 (4 wins and 3 draws). She is doing very well and I hope she continues to play great chess
Oct-19-13  Caissanist: The world junior was not kind to Deysi this year, since she lost to a 14 year old (who won the tournament) and a 13 year old (who came second) in the 11th and 12th rounds, both times with the white pieces. This was her last world junior, must have been a bitter pill for her.
Nov-01-13  Firststep2: Fantastic game by Deysi!
Deysi Cori vs Alberto Angulo
Sep-11-15  sonia91: Does anyone know why she isn't already an IM? She qualified for the World Cup already in 2013, now it's the second time she get into this competition. FIDE handbook says those who qualifies through play are awarded the title of IM.
Sep-11-15  ChessVip: <<sonia91>: Does anyone know why she isn't already an IM?> She had 6 IM norms or more, but she never claimed the IM title.
Sep-11-15  sonia91: I've read it in the bio above, but if she qualified for the World Cup shouldn't she be awarded <authomatically> the IM title by FIDE? The African players playing in the World Cup, including the one who draw with Giri, gained the IM title by qualifying for the World Cup
Sep-11-15  Catfriend: Bold play against Kramnik today, perhaps too bold.
Premium Chessgames Member
  perfidious: <torrefan: Nakamura's beautiful first round opponent at the 2013 world cup. I hope he loses concentration.>

I never would, especially in the post-mortem.

Sep-11-15  SickedChess: <<sonia91:>... if she qualified for the World Cup shouldn't she be awarded <authomatically> the IM title by FIDE?> Deysi was third in the Zonal 2.(only the first two qualify) but replaced her brother Jorge who prefers to play the World Juniors 2015 (Khanty-Mansiysk)
Sep-11-15  sonia91: <SickedChess> Deysi finished equal third in the American continental championship 2013 and qualified to World Cup 2013...
Sep-11-15  SickedChess: <sonia91> those are differents tournaments, Zonal only gives 2 places while the Continental gives 5 places for the World cup. And the automatic IM title is for the winner (IM Norm for the second and third place)
Premium Chessgames Member
  eternaloptimist: Happy birthday to this beautiful young lady! I see that Jorge Cori isn’t the only intelligent member of his family; his older sister Deysi is as well!
Premium Chessgames Member
  technical draw: Yesterday was her birthday. She turned 29. Next birthday she will be GM Cori.
Premium Chessgames Member
  technical draw: Sorry. I didn't know that WGM is a lower title than IM. So Cori has to get the IM title first but it appears she already has the qualifications.
