Background

Championships

<Age> In 2003, So became the Philippines U10 Champion. He has competed in World Youth Championships in 2003 (19th in the U10 division), 2004 (14th in the U12 division) and 2005 (=1st in the U12 division). In the 2005 event held in Belfort, he finished equal first in his age group alongside Srinath Narayanan, Sanan Sjugirov and Samvel Ter-Sahakyan with Narayanan taking the title on tiebreak. On 9 May 2007, So won the National Junior Championship at the age of 13years and 7 months, the youngest to do so until FM Paulo Bersamina won the 2010 edition of that event while still 12. So earned his 2nd GM norm in September 2007, shortly before he turned 14, at the World Junior Championship (2007) (his 1st GM norm being in Germany soon after he turned 13 – see below in the classical tournaments section) held in Yerevan, Armenia.

<National> So holds the record for the youngest National Champion of the Philippines, first winning the title in 2009 at the age of 15 years and 6 months. He also won the Philippines Championship in 2010 and 2011 after coming second in 2008 and first in the "Battle of the Grandmasters' event in 2008. Starting from 2009, the "Battle of the Grandmasters", previously a separate event, also became the national championship.

<Continental> In September 2007 while still 13, Wesley played in the Asian Individual Championship (2007) that was held in Cebu and scored a par for rating 6/11, drawing against four GMs and losing to one. He scored a modest 6.5/11 at the 8th Asian Continental Chess Championship (2009) held in Subic Bay but came 2nd by a half point behind Ni Hua in the 9th Asian Continental Championship held in April 2010 to qualify for participation in the 2011 World Cup.

After qualifying in early 2009 by coming 2nd behind Darwin Laylo in the 3.3 Zonal held in Ho Chi Minh City, Wesley made a splash at the World Cup (2009) by defeating Gadir Guseinov, Vassily Ivanchuk and Gata Kamsky in the first three rounds before falling to Vladimir Malakhov in the rapid game tiebreaker during the round of 16. He defeated Chinese GM Ding Liren in the first round of the World Cup (2011) but lost the second round in a hard fought rapid-game tiebreaker to Russian number 1 and world number 5 GM Sergey Karjakin.

A few days later, Wesley So competed in the 3rd Singapore Masters International Open placing =10th with a scored of 6/9 including wins against GMs Susanto Megaranto and Li Shilong.

The start of 2011 saw him place =4th in the Tata Steel (Group B) (2011) with a creditable 7.5/13, a point shy of the lead, while his subsequent participation in the Aeroflot Open (2011) was cut short after 6 rounds due to his withdrawal from the event because of exhaustion.

In June 2011, he came =1st alongside Giri and Hans Tikkanen at the 19th Sigeman & Co Chess Tournament (2011) in Sweden.

His 5/10 at the SPICE Cup (2012) was basically par for rating. Several months later, an excellent =1st (2nd behind Pavel Eljanov), with 8/10 at the powerful Reykjavik Open (2013) enabled So's rating to surpass 2700 for the first time.
