This month, I find the notorious Mr. Rausis listed between Matlakov and Jakovenko, not rated in any format, federation given as FIDE, and his profile shows he still has the titles of IM, FIDE trainer, and astoundingly, FIDE arbiter. It takes a thief to catch a thief?

  beatgiant: My curiosity was piqued when I found that Firouzja is not the only player whose federation is listed as FIDE. I decided to make a top 10 list of players without a country. I list here the full name, rating and title of these players.

Criterion: Players whose federation is listed as FID on the FIDE profile.

1. Firouzja, Alireza 2728 GM

10. Lebedinsky, Eduard 2168

I'd be very interested to learn their stories, if anyone knows.

Premium Chessgames Member
  beatgiant: All the info I found so far:

Alireza Firouzja Originally from Iran, stopped playing for Iran in 2019 after his federation ordered its players to withdraw from the World Rapid and Blitz Championship as part of that country's quasi-official ban on playing chess with Israeli players.

Arian Gonzalez Perez Originally from Cuba.

Katashuk, Uladzislau: Name suggests Belarus origin.

Eduard Lebedinsky Originally from Moldova.

Rifai, Abdulkader: Name suggests origin in the Islamic world.

The rest have names that suggest origin in the Spanish-speaking world. My first guess would be Cuba, as a country that is Spanish-speaking, has a lot of good chess players, and has a lot of exiles.

  beatgiant: Inspired by the "Rest of World" team in FIDE Chess.com Online Nations Cup (2020), I decided to make a "Rest of World" list.

To qualify, the player must be from a national federation which is not in the EU or Semi-EU, not Nordic/Baltic, not former USSR, not post-Communist, not former British empire, not Asia, not Latin America, and not Middle East.

So what's left? A few small Western European countries that are outside the European Single Market, a few places in the Caribbean and South America that are not former British, Spanish or Portuguese colonies, African countries that are not former British possessions, and Oceania.

For the purposes of the list, I defined Indonesia as a part of Oceania, and as always, I defined Egypt as Middle East while African countries to the west of it are not.

I wasn't able to check my work carefully this time, so any corrections are welcome.

  beatgiant: Again no events this month, but I've started another special project and I'll post a few results as time permits.
Jun-04-20
Premium Chessgames Member
  beatgiant: And now I'll post a little from my latest project: generational timelines around top players of the past.

This time, I will provide some data on the question, "Were there noticeably fewer top GMs born in the USSR during WWII than before and after?" It's often said that the demographic impact of WWII included a birth dearth in the USSR which was felt in chess in the 1970's when that missing generation would have reached the peak chess playing age.

It sounds very plausible, but like the man said, "Without data, you're just another person with an opinion."

For my methodology, I looked for top Soviet GMs born in every year from 1929 to 1950. I used chessmetrics rankings and defined a top GM as anyone who had ever been in the top 30 on chessmetrics.

Here is what I found: (year of birth, name, top chessmetrics ranking ever achieved)

1929, Petrosian, #1
1930, Krogius, #17
1931, Korchnoi #1, *Nei #21
1932, none found
1933, Vasiukov, #11
1934, Polugaevsky, #2
1935, A. Zaitsev, #21
1936, *Tal, #1, Gufeld, #30
1937, Spassky #1, *Gipslis #20
1938, none found
1939, none found
1940, Savon, #7
1941, none found
1942, none found
1943, Sosonko, #21
1944, Tseshkovsky, #7, Dzindzichashvili, #15
1945, Alburt, #28
1946, Kuzmin, #12
1947, Gulko, #8, Dvoretsky, #29
1948, none found
1949, Balashov, #11
1950, Lerner #17, Sveshnikov #20

*Nei, Tal and Gipslis were brought under the Soviet system since the 1940 annexation of the Baltics.

And now, my conclusions.

The USSR was reliably turning out about 1 top GM per year over the period.

We see a cluster of years (1938, 1939, 1941, 1942) when I found none born, but it only partially overlaps WWII. So if it's true that there was a "chess birth dearth," I don't think the explanation can be as simple as "They weren't born because the guys who could have been their fathers were on the front lines fighting Germans." It could also be something like "The NKVD purged the medical profession in 1937, and kids born in the following few years received poor prenatal and post-natal care, impacting their cognitive abilities and thus limiting their ability to become top chess players."

Or it could simply be random chance. I don't think we have enough data here to make a strong statistical statement.

Of course, it's also possible I simply overlooked some people. If so, as always, I welcome any corrections.

I also found none born in 1932 and 1948. 1932 was a year of famine, but I don't have any explanation for 1948 beyond random chance.

  beatgiant: (One minor correction to the above already, Dvoretsky's top chessmetrics ranking was #20, not #29.)

  alexmagnus: <but I don't have any explanation for 1948 beyond random chance.>

Another famine? There was a famine in the USSR in 194<7> (the post-war famine, which was also the last famine in the Soviet Union at all - and which, unlike the 1932-33 famine, was not kept secret from the popuation pre-perestroika).

Jun-05-20
Premium Chessgames Member
  alexmagnus: As for 1938-39, while the birth years do not overlap with WW2, the chess learning years needed to become a top player do. Spassky, born in 1937, learned chess on an evacuation train...
Jun-05-20
Premium Chessgames Member
  beatgiant: <alexmagnus>
Good points. Then, it seems all the gaps have a neat explanation. Interestingly, it seems Savon, the sole example I found of a top Soviet GM born in the 1938-1942 years, learned to play only at age 13.

The next case I'm working on is WWI. I've seen it claimed that the top players in the 1930's were older than usual because of some kind of effect of WWI.

Does it mean we expect to see fewer top players from European belligerent countries who were born in years that would make them eligible for conscription from 1914 to 1918? It sounds like lots of work to investigate that, so it may be a while before I post anything.

Jun-05-20
Premium Chessgames Member
  beatgiant: I start with an obvious theory: there was a big drop in the birth rate in Europe during WWI, and it's relatively easy to investigate its effect on top chess.

This time, I looked for top players born in WWI belligerent countries from 1910 to 1922, listing anyone who had ever been in the top 30 on chessmetrics. Here's what I found. Again I give year, name and highest chessmetrics ranking achieved.

1910: Najdorf #2, Tolush #10, Konstantinopolsky #11, Mikenas #12, Trifunovic #12, Book #24

1911: Botvinnik #1, Reshevsky #1, Lilienthal #6, Barcza #16, Novotelnov #20, O'Kelly #27

1912: Nezhmetdinov, #21, Veresov #21

1913: Kotov #3, Eliskases #7, Bondarevsky #13, Bely#25

1914: Pilnik #12

1915: none found

1916: Keres #2

1917: Szabo #6

1918: Katetov #16

1919: Boleslavsky #3, Simagin #21

1920: Furman #11, Aronin #18

1921: Smyslov #1, Ilivitsky #29

1922: Averbakh #8

Conclusion:
Until 1913, Europe was producing about 5 top players per year, most of them in the Russian empire. It fell to about 1 a year in 1914-1918, and then partially recovered to about 2 a year in 1919-1922. So yeah, it does look like WWI had a big impact on top chess players. But considering typical peak playing ages, I think this would affect chess in the 1940's more than the 1930's.

Premium Chessgames Member
  alexmagnus: < think this would affect chess in the 1940's more than the 1930's.>

1940s were too overshadowed by WW2. I mean, how many tournaments during the war have left any mark in chess history?

It goes as far as when the first 27 grandmasters were awarded their titles in 1950, almost none of them got it to their achievements during the war. The batch of honorary grandmasters in 1977 and another one in 1993 was created to compensate for this omission - many of those honorary GMs peaked during the war.

  beatgiant: <alexmagnus>
Yes, as far as I can determine, not a single player born in the USSR between 1938 and 1950 ever made it to the Candidates, stark evidence of a lost generation in a country that was generally producing one world champion per decade over a long period of time.
Jul-01-20
Premium Chessgames Member
  beatgiant: Again no events this month, but I will post some more findings about the WWI lost generation effects, if time permits.
Jul-01-20
Premium Chessgames Member
  beatgiant: My next step was to try to quantify what we mean by <peak playing age>.

First, I assumed that the typical "growth, peak, decline" pattern in chess skill must be biological in nature, so it should remain constant across historical eras, even though we have the cultural phenomenon of children starting to master chess younger and younger.

Based on that assumption, I then looked at the peak ages of the top 30 players in the chessmetrics 1-year peak list. I found that the minimum is 20 (Kamsky), the first quartile is 28 (Anand, Fischer, Pillsbury), the median is 32 (Spassky, Tarrasch), the third quartile is 36 (Janowsky, Najdorf), and the maximum is 49 (Steinitz).

The data does show some trend toward the peak age getting younger and younger through history, which challenges my assumption above. But that's a project for another month.

Nevertheless, it seems reasonable to me to take ages 28-36, spanning the second and third quartiles, as a model of <peak playing age>.

Jul-02-20
Premium Chessgames Member
  alexmagnus: I always assumed there being two peaks actually, around 27 and around 37.
Jul-02-20
Premium Chessgames Member
  beatgiant: <alexmagnus>
<two peaks>
That's another interesting question which I could tackle in another month.

But I don't think it will change my current analysis much. My next step was to look at the number of 28 through 36 year olds among the top players during the 1920's and 1930's to find post-WWI evidence of a lost generation. If 27 and 37 are the real peaks, it might shift the period of the effect by a year or two at most.
