WESLEY SO
(born Oct-09-1993, 23 years old) Philippines (federation/nationality United States of America)

[what is this?]

Born in Las Pinas, Philippines, Wesley So is a Filipino/American chess prodigy who attained the GM title at the age of 14 years, 1 month and 28 days. That made him the youngest GM in the world at that time. He was the Philippines' youngest ever International Master, youngest ever Grandmaster and the youngest ever National Champion.

Background

Wesley was only six when he learned the movement of chess pieces across a board. After memorizing them, chess set in hand, he explored the streets of his neighborhood daring people to play with him. At nine years old he began to compete in local, junior chess tournaments.

His first major tournament win was taking 1st place at the 2003 Philippine National Chess Championships for the under 10 age group.

So, was awarded his first GM norm at the Offene Internationale Bayerische Schach Meisterschaft, in Bad Wiessee, Germany. He acquired his second GM norm in the World Junior Championship (2007) in Yerevan, Armenia, and capped his year by earning his third GM norm at the 3rd Prospero Pichay Cup International Open in the Philippines. At the age of fourteen years, one month and twenty eight days, FIDE awarded him the title of Grandmaster, making him the ninth youngest chess grandmaster. He was then ranked strongest player in the world under sixteen years old.

In 2006 at the age of twelve years and ten months Wesley So became the youngest ever Filipino International Master and the youngest member of the national men's team to participate at the 37th Chess Olympiad in Turin, Italy.

In 2007, Wesley So went on to become the youngest National Junior Open Chess Champion and won the gold medal on board one, at the World Under16 Team Championships.

So won the title in the Dubai Open (2008), "The Sheikh Rashed Bin Hamdan Al Maktoum Cup", in the United Arab Emirates, and set a record as the youngest winner in the 10-year history of the Cup. Later that year, Wesley So was rated 2610 and was the youngest player in the history of the game to break the 2600 Elo barrier, surpassing the record previously held by Magnus Carlsen.

In 2012 he emigrated to the United States, and in 2014 he officially shifted his chess affiliation to the USA. In March 2016, So received the $42,000 Samford Fellowship. (1) In early 2017, So partnered with veteran player and coach Vladimir Borisovich Tukmakov. (2)

As of April 2017, Wesley So is the USA's top player, as well as the #2 player in the world.

Rating and Ranking

Wesley So was the youngest player ever to cross the 2600 rating mark, 9 days before his 15th birthday, until 2013 when Chinese prodigy Wei Yi achieved the mark at the age of 14 years 5 months 23 days. In March 2013, So's rating crossed over to 2701 (the 92nd player to achieve 2700). In January 2017, So's rating was officially 2808. His April 2017 rating of 2822 makes him the 2nd strongest player in the world, behind only Magnus Carlsen.

  AylerKupp: <<MannyGarry> If you look at section 1.49 table 8.1.a in your link, you can see there the -800 and +800 as extreme values for rating difference dp.>

Yes, the FIDE tables cover the range 800. The original table calculated by Dr. Elo had a range of 736, with dp = 0.00 if RD < 735 and dp = 1.00 if RD > 735 appears in Dr. Elo's book "The Rating of Chessplayers, Past and Present" which was first published in 1978 although it must have been used in the first official FIDE ratings in 1970 and probably in Dr. Elo's unofficial FIDE ratings in 1966. FIDE just extended them to 800 and I use 1000 to handle even more extreme cases without having to check if the RD exceeds the limits. Since FIDE's current rating floor is 1000 and no player's rating has (yet) exceeded 2900, I could have gotten away with a range of 900 but I suspected that as soon as I did that Murphy's Law would become effective and someone's rating would exceed 2900 and I would have to extend my tables. So at least this way I think I'm safe for the time being.

But the rule of 400 (which was established in 2009) and its predecessor, the rule of 350 (which was established in April 2006) are completely artificial and arbitrary. The Rule of 350 was proposed by Anand because he (and presumably other grandmasters) did not want to lose a lot of rating points if they lost to a much lower rated player. It was seen as an incentive for top-rated GMs to play in Open tournaments when a large rating differential was possible.

John Nunn has indicated (http://en.chessbase.com/post/elo-od...) that the rule was introduced to prevent a player from losing rating points by winning a game. But I don't see how, using the FIDE rating Rules and Regulations, this would be possible since if RD is sufficiently large (>735), the higher-rated player's expected score would be 1.0, just like his actual score. So the worst that would happen is that if the RD is sufficiently large, the winning player would not gain any rating points even if the won. But, of course, he would lose a significant number of rating points if he drew or lost.

My opinion is: If a player with a rating much higher than his opponent doesn't want to lose any rating points, he should win the game. After all, he is expected to win. And, if he did draw or lose and therefore lost a lot of rating points, he would be grossly underrated and would stand to regain those lost rating points soon enough.

  AylerKupp: <<MannyGarry> Here's my point in an example.>

I get the exact same rating changes using the FIDE formulas after rounding:

So / Carlsen rating differential = 2810 – 2822 = -12

Scoring probability = SD(-12) = 0.48286

So's rating change in case of loss = 10*(0.5 - 0.48286) = -4.8286 = -5

So's rating change in case of draw = 10*(0.5 - 0.48286) = 0.1714 = 0

So's rating change in case of draw = 10*(1.0 - 0.48286) = 5.1714 = +5

And I get the same rating changes using FIDE's Table 8.1b with only 2 digits of precision so that SD(-12) = 0.48.

The two formulas yield very similar results if the calculations are done to 4 or more significant digits. This is clear when you plot them, and I calculated a standard deviation of only 0.00812 when the results are calculated to 5 significant digits in the range of 1000 and 0.00872 in the range of 800. And, because of the rounding of the rating change to the nearest integer per section 8.67 of the FIDE Rules and Regulations, the rating change is the same.

So, yes, "It seems like ..." is an accurate observation.

One minor quibble. I think that if you're calculating So's rating change when playing Carlsen (i.e. from the viewpoint of the player) then So's rating differential should be negative; i.e. So's rating – Carlsen's rating = -12. It will, of course (at least at this moment) be positive against anyone else. Then, in order to get the right values, you need to use the formula Expected Score = 1 / (1 +10^(-RD/400)). But that's just my opinion, it makes no difference either way.

  AylerKupp: <joeyj> That's the list of the 128 players that qualified for the World Cup. I have not been able to find a list of who's actually playing but I doubt that either Carlsen or Karjakin are playing since as world champion Carlsen obviously doesn't need to qualify for the 2018 Candidates Tournament and Karjakin has already qualified by virtue of losing his match against Carlsen. So their only reason for playing would be for the money. Then again, that might be a sufficient incentive.

I assume that the actual list is much longer so that, as players who qualified decline to enter, the 128-player field can be filled up with those next in line. We probably won't find out who's actually playing for another month or so.

https://www.chess.com/news/view/mag... This does not seem good. He might be there to eliminate his most dangerous opponents without the risk of himself being eliminated in the World Championship. Strategic foresight by the world champion. Clever. If this is true, Wesley is somewhat safe however having a lifeline in December to capitalize on.

What complicates further the World Championship cycle, as reported in chess.com, is if Carlsen participates in the Candidates tournament....hehehe...

  jimmy77: The idea of Carlsen participating in the Candidates can complicate as well Wesley's qualification to the Candidates. If Carlsen will compete in the Candidates on the basis of the average rating criterion, to ensure Wesley's qualification to the Candidates, he has to make sure that he ends the year with a higher average rating than Caruana and Kramnik.

They are just the same.

But I like the following because I don't have to add -RD in the formula.

SoRD = OppRating - SoRating

is automatically usable to the formula:

SoExpectedScore = 1/(1 + 10^(RD/400))

Jul-25-17  knightF5: Hi Jimmy, allow me to speculate.
Name/ Aug17 Rating/ Average 8 mo/ Total 8 mo
Wesley So 2810 2815.1250 22521
Fab Caruana 2807 2814.0000 22512
Vlad Kramnik 2803 2809.7500 22478

For Kramnik to overtake Carauana’s total average on Dec 2017 FIDE rating. Granting Caruana maintains his 2807 until December.

Name/ Sep/ Oct/ Nov/ Dec/Average 12 mo
Fab Caruana 2807/2807/ 2807/2807/ 2811.6667
Vlad Kramnik 2816/ 2816/ 2816/ 2816/ 2811.8333

Kramnik has to up his rating to 2816 for the next 4 months to overtake Caruana. He can still afford to be 2815 in one of those 4 mos and still overcome Caruana.

For Kramnik to overtake both Wesley and Caruana.

Name/ Sep/ Oct/ Nov/ Dec/Average 12 mo
Wesley So 2810/ 2810/ 2810/ 2810/ 2813.4167
Fab Caruana 2807/ 2807/ 2807/ 2807/ 2811.6667
Vlad Kramnik 2821/ 2821/ 2821/ 2821/ 2813.5000

Vlad has to up his rating to 2821 Sept – Dec 17 to gain top spot rating qualifier.

Jul-25-17  knightF5: On second thought, Carlsen's participation at the World Cup may actually benefit Wesley. If Carlsen could eliminate 1 or 2 dangerous candidates would be in the likes of Mamed, Aronian or MVL. Mamed and MVL are not yet sure of topping GP. Their fates are no longer on their hands.

Wesley's chance is still on his hands - 50% of it.

Wesley may even defeat Carlsen at the World Cup.

Let Carlsen joins the World Cup!

Jul-25-17  starry2013: I don't really see Carlsen competing in the Candidates tournament at all, he would prefer surely to keep his preparation for any challenger to one side.

The World Cup is another matter entirely, it's one of the biggest chess tournaments and events whether there's qualifying places to the Candidates or not. I'm not surprised Carlsen wants to win it.

  AylerKupp: I don't see Carlsen participating in the 2018 Candidates Tournament either. For one thing, he is not eligible to participate.

  AylerKupp: At any rate, if Carlsen were to qualify for, enter, and win the 2018 Candidates Tournament, it would be a very one-sided World Championship match. :-)
Jul-25-17  Karpov2985: <AylerKupp> I don't think Wes gain any ELO points considering he has the 2nd highest ELO rating. Maybe you mean he gain 5 points by winning.

  jimmy77: Unless the rules and guidelines governing player qualification to the Candidates as well as the Candidates tournament itself explicitly mention the exclusion of the current World Champion (sometimes, it is the obvious that is missed; taking for granted what is perceived to have already been understood by everyone), then by virtue of the qualification via average rating, Carlsen is the leading contender for qualification to the Candidates tournament.
