<chessgames> ha, that post is only two weeks old, but it seems like ages ago!

As for terminology, I steal a lot from math and physics. If there's a degeneracy between the two - go with the physic's one.

Degeneracy - as in two or more separate entities which appear identical at some level.

(http://en.wikipedia.org/wiki/Norweg...)

So in physics, like degenerate energy-levels.

For the case at hand, it's in reference to two players sharing the same name.

So, we have a <CG> player (w/o FIDE #) and try to find the corresponding <FIDE> player. The first step is to match the names.

Often that yields several <FIDE> players with the same name, i.e. a degeneracy.

The analogy/terminology isn't as far-fetched as might appear at first. In quantum physics a degeneracy allows mixing of states, here we run the risk of mixing the players.

In physics people talk about degeneracy-breaking. There's an apt parallel here as well.

Etc., etc.

But yes, I was surprised to see so much biographical data on a player, stopping just short of filling in the <FIDE> id.

I think the biographers do a fantastic job in this department, and often utilize NIC data (that's my suspicion).

It's a forum of public interest. Please consider clicking the "expiry date" to 2099 and linking the forum to the front page?

You did have plans to do this, but no time like the present, since the forum is now gone.

Luckily, all of the history of "chess booking" can be turned on again with a flick of your switch!

<cg>, please correct me if I remember this wrong - but I seem to recall that the ability to enter FIDE id was given to the editors later than the ability to write bios? If that's the case, the players with bios entered, but missing FIDE ids, may well be the biographies filled in before the editors were able to enter ids for them.

Me, whenever somebody refers to me as a degenerate, I've always considered it a bit of a compliment.

Similarly for reprobate.

Annie is right:

<I seem to recall that the ability to enter FIDE id was given to the editors later than the ability to write bios? If that's the case, the players with bios entered, but missing FIDE ids, may well be the biographies filled in before the editors were able to enter ids for them.>

The FIDE field came *much* later than the biography feature itself. I suspect that many of these cases are exactly from that time period.

<BTW, on 'degeneracy', <zanzibar>, I would kinda prefer using some alternative term too. :) Because it may be worth bearing in mind that we're talking about people, not abstract data.>

I would prefer to use another term as well, although not because so much because of the layman's interpretation of "degenerate" — just that it has a meaning in computer science which doesn't mesh with how zanibar is using it. Comp sci and physics share a lot of terminology in common (entropy etc.) but in this case it's not being used properly IMO.

In my mind, a degenerate player record would be one without a name, or something crazy like that. A problem that happily we are without.

(Annie has a point too, though. Imagine googling your name, and reading that you are a case a degeneracy in the world of chess. That could be easily misconstrued.)

Unless there's a compelling reason, let's just call these "duplicate player records", or "dupes" for short.

So it looks like we solved the "impedance" mismatch, and just need to add the easy ones in to catch up.

I forgot about the nationality. Thanks for reminding me.

No, I didn't use it, but I certainly eyeballed those columns.

I have all the FIDE and CG fields available for comparison. The trouble with the CG 2-letter codes is that they're undocumented afaik.

I could guess, or reverse-engineer them if needed. But I'm sure we could generate a CC2-to-CC3 converter. The topic was briefly mentioned long ago iirc.

We put it to the side then, but as Charlie Parker says... "Now's the Time".

The reason is simple, those most likely to share a name come from a country where the name is most common - usually the same country.

Thank you very much!

Now I'm immortal.

? ? ? ;)

<...or "dupes" for short.>

Because who wouldn't love being called a dupe! :p

The nationality can only help. I didn't use it because the dob match was so strong it wasn't needed (it was in the back of my mind of course - but I like baby steps when exploring).

For the more challenging degenxxxx-dups, it should be in the toolbox.

(Ever see the Prisoner? I always loved the xxxxxxxxx-ing part in the intro)

<zanzibar> good point, though there's a lot of Slavic names that still could come from any number of Slavic countries.>

1680s, from French dupe "deceived person," from Middle French duppe (early 15c.), thieves' jargon, perhaps from phrase de huppe "of the hoopoe," an extravagantly crested and reputedly stupid bird.>

From one of my favorite resources:

But only clicking on the 'game title' link triggers the move addition to the URL. Clicking on the 'move' link on a single game line hasn't been updated, or should I just try being a little more patient? ;)

So if I put (the full url).../chessgame?gid=1633851&m=37.5 in a post, it would show up as

click for larger view

Ponomariov vs L Bruzon, 2011

(with the game title in smaller script and centered under the diagram).

Then either clicking either part would act as a link to the game, or clicking the diagram would get the usual pop-up, and clicking the game title would take us to the shown position in the game.

I submitted games for that tournament on at least two occasions. The first, apparently back in 2011, was around 200-225 games. That was before tournament pages, and my preference was to use "US Open" for event.

After the tournament was promoted, with the Event name "56th US Open", I came acroos another hundred or so games. This would have been the 2014 load which you mention. Since the tournament page had established the Event as "56th US Open", I tried to use that in the second load. Apparently, for the 17 games I reverted to my preference and used just "US Open".
