Jun-30-14  The Last Straw: What is a *Chicago Master*?
Premium Chessgames Member
  perfidious: Our esteemed User: FSR might be able to shed some light on this mystery.....
Premium Chessgames Member
  FSR: I know Kus. We were teammates in high school, and have played three rated games: he crushed me when I was a high school freshman, then we had two short draws after I got stronger. A "Chicago master" is simply a master who lives in Chicago. From the USCF website, it appears that he has moved to California, and hasn't played a rated game since 2003.
Jul-01-14  zanzibar: USCF master I presume.

I couldn't find a FIDE card for him. Did I miss it?

Premium Chessgames Member
  FSR: <zanzibar> AFAIK, he doesn't have a FIDE rating. Nor do I.
Jul-01-14  zanzibar: <FSR> yer right - can't find you either!

Maybe FIDE rated tournaments are more common on the two coasts than in the midwest?

PS- I think titles, if not FIDE, might be better understood if the national affiliation is used... "USCF National Master" vs "National Master".

Just my opinion of course.

Premium Chessgames Member
  FSR: <zanzibar> Maybe; there aren't a lot of them around here. <National Master> seems pretty self-explanatory to me - a master title conferred by the federation of whatever country the person lives in.
Jul-01-14  zanzibar: <FSR> there could be a snowball effect, since you need FIDE players to get FIDE ratings. Maybe more of the chess diaspora ended up on the East/West coasts.

I thought "National Master" was part of the title. For the record then, my pref would be "USCF Master" (or ECF/DSB/etc Master).

Premium Chessgames Member
  FSR: <zanzibar> That is the title. When one gets a rating of 2200 or above, the USCF sends one a certificate recognizing one as a "National Master."
Jul-01-14  zanzibar: <FSR> Sorry Fred, but I messed up the search for your name in my FIDE data - you are there!

No FIDE rating, but two entries from 2013 give you a Rp of ~1900.

Premium Chessgames Member
  FSR: <zanzibar> Thanks. Not sure how you came up with ~1900. In those two tournaments, I had wins against players with FIDE ratings of 1933 and 1886, and draws with a 2028 and a 1952. (2333 + 2286 + 2028 + 1952)/4 is about 2150 if my math is correct.
Jul-02-14  zanzibar: <FSR> Generally, whenever dealing with a rating calculation one should be very careful.

When dealing with someone else's rating one should be doubly careful - which I wasn't. Humblest apologies.

OK, if you look on your FIDE card there are two tournaments listed - each of which has a ratings breakdown of you and your opponents:

<2013 Greater Midwest Classic (USA) Rosemont, Illinois 2 3 1986 August 2013>

<2013 NACA July - August Game 90 Friday Night Series (USA) Skokie, Illinois 1 1 1901 September 2013>

FIDE quotes the Rp for each tournament, 1986 and 1901. I intended to copy the highest and instead copied the lowest. (Again, apologies)

Actually, the best way to get a FIDE provisional is to take the average of the opponent's rating and your score (plus number of games) to the FIDE calculator:

or, more directly for an initial rating:

The FIDE initial rating is different from the USCF provisional (the latter uses the +400/-400 offsets for wins/losses). Instead, FIDE just uses the average of all your opponents:

Rc_ave = (1933+2028+1952+1886)/4 = 1959

W (score) = 3 (+2 -0 =2)

N = 4

Rp = 1989

So I nicked you about 100 points, rather unfairly.

But maybe there's a couple of useful lessons - first, for me to be more careful. And to compare FIDE's more conservative initial rating vs USCF's.

Premium Chessgames Member
  FSR: <zanzibar> I score 3-1 against opponents rated 1959, and FIDE gives me a performance rating of 1989 (a walloping 30 points higher) for that? Bizarre. But thanks for the information - good to know.
Jul-02-14  zanzibar: <FSR> And to finish, suppose you have a FIDE rating of 2000, and K_val = 30.

Here's FIDE's rather stingy rating bump for wins/losses against various opponents:

1800 : +7.2 / -22.8
2000 : +15 / -15
2200 : +22.8 / -7.2
2400 : +27.6 / -2.4

So, even if you won 6 games in a row from a 2000 rated opp, you still wouldn't gain 100 points.

  perfidious: <FSR> needs to whale on an old retired fish like me--that would give him a nice bump, if I can still remember how the pieces move!
Jul-02-14  zanzibar: Yeah, I found a "whale" too:

Looking at my archives, last played 9 games in the rating period prior to 2001-07. Might be ripe for the picking... but then again...

Gotta be careful with these "old" whales though - they can catch you unawares if their danger (2187) is foolishly underestimated.

Jul-02-14  zanzibar: Gotta worry about the young'uns too...

Clearly <nine-year-old FM Nodirbek Abdusattorov> is under-rated.

The rate of increase in his rating is perhaps "too slow".

I know that once-upon-a-time older USCF masters staged a semi-revolt due to rating's instability introduced by the influx of young hot-shots like Abdusattorov.

Perhaps there's no good solution to this problem. But the FIDE 2600 GM's lost ~ -27.6 rating points vs -15 rating points if Abdusattorov really was a 2600 player.

  perfidious: <zanzibar> You may have read or heard an old John A Curdo saying: 'Gotta get 'em while they're young'.
Jul-03-14  zanzibar: Nine years old is almost embryonic. (Wonder who his coach is.)

BTW- the CB article was written by a 10th grader!
