I am new to this site and wondering can someone tell me how the ratings are arrived at? I'm primarily interested in how for the extinction chess. I see players with better won/loss ratios that have lower ratings than
someone with a worse won/loss ratio.
Is there anywhere on this site that explains how the ratings are arrived at etc?
Thanks

You have to push down the lid to open them.

OK not really! Go to 'settings' and tick 'show smileys'.

Why can't I get all the smileys on my computer? is there a child lock

Welcome rtv. :-)

The wins/losses ratio is useful in conjunction with the rating but is not directly comparable. It depends on the ratings of your opponents, so, for example, a high win count against weak players will not achieve a high rating.

Here's the brief BrainKing explanation.

And here are two in depth articles on the formula. It's a chess formula but is used for all games. [so far, hint hint, Filip, lol]
USCF Rating System and Chess ratings.

They're a bit mathematical but have a read of them and see how much sense they make.

ClayNashvilleTn: k

Fencer: Yes, I'd like that too. That's make four options, right? Active Provisional, Active Established, Inactive Provisional, and Inactive Established?

I must exert my roving Mod skills again and tactfully ask you guys to CHAT idle stuff on General. PLEASEEEEEEE

playBunny: It cost me a bundle so don't pick. ;)

ArtfulDodger: "Raving Mad" and that hair!!

BIG BAD WOLF: A bug. Will be fixed.

Not sure if it's a bug or if it is suppose to be this way.

In the games which I have not completed a game for awhile (lets take Maharajah Chess for example), even though I do have a rating, it shows me as "unrated" while playing a game.

I would still think it should show my rating during a game, but just keep me off the "high ratings" list.

Example game: http://brainking.com/en/ShowGame?g=999430

So is it suppose to be like that, or is it a bug?

ClayNashvilleTn: You spelled it wrong

it's Raving Mad

ArtfulDodger: I have been ANOITED Roving MOD. I will consider your request.

harley: just make me a temp mod. I'll keep things in order in here for ya!

harley: "WOMEN" SHOPPING WITH MENS MONEY" Must I say more?

Yes.. Grim, A good way to weed out the players who no longer are here and playing..

I, for one, am happy to see that "Nellaf" is finally gone from the Gothic Chess rating list So thanks for that.

There seems to have been a lot of "dead wood" on the lists, in some cases 40% - 50% of the players were pawns clinging to the posts. Has anyone else noticed that?

harley: Grabs sweater and purse.. let's go.. HMmm.. LQQks around.. and snatches CC's from all the males on the boards.. Come on Harley.. whoo hoo.. lotsa moola here.. :)

Can I ban everyone so I can get my shopping done without wondering what I'll come back to?!

ClayNashvilleTn: Please make me a temp mod of this board so i can ban clay!!! He's making fun of my hair.

harley: Let me BAN Fencer Harley if it becomes necessary!

Scarlet do keep up dear Its reza - I've been posting about it for a while!

who is the next victim..?? I mean hehe.. player selected to be interviewed??

ROFL will do!!

harley: Feel free to ban me if I follow up.

End of discussion.

Thanks Clay, I just sent personal messages saying just that :o)

Grim Reaper: You re-read the contract, Edward. It uses the words "description of the rules of the game". And I am the one to decide which pages fulfil these conditions.

It was going on via PM, and Fencer was not answering me.

Thanks for butting in Clay, as usual.

This sounds like a personal matter best handled in private, gentlemen.

Please delete your post and continue your conversation through PM.

Re-read the contract Filip. It uses the words "game description".

Bull. The only place I am supposed to show this information is the game rules page [where it actually appears]. Please stop spreading the nonsenses.

Gothic Chess is my intellectual property. I have your signature on a document stating that my name will appear with ALL descriptions of that intellectual property being represented on BrainKing.

AbigailII: Thank you Fencer and AbigailII for your kind explanations. I had the false impression that the BKR were erased since I've just started a new Janus Chess game (ID: 999199) and no BKR appears around the board as usual ("not ranked" message, only).

Again, if BKR remain unchanged there is no problem at all!

Thank you... and let's play!

tycho: Your BKR for Janus Chess is not unknown - it's 1238. You are, however, no longer listed in the charts. I didn't get the impression that inactivity (or activity) is taken in account when calculating the ratings. Only the fact whether or you you're in the list matters. So, for paying members, one quick draws against someone with a similar rating twice a year is enough to keep you in the charts.

This is unlike say, the rating system on FICS, where they, beside keeping the rating, also keep a stat that measures activity - it's an indication how good established your rating is. The more you play, the less your rating will fluctuate (but the more it can fluctuate the rating of your opponent). If you play less, your rating fluctuates more after a win or loss. So, on FICS, having played 400 games way back means a new win or loss can change your rating a loss (just like you have only played a few games here), much more so than if you have only played 20, but all of the recently. And the same statistic is used to determine whether your rating is established or not. So if you have played 400 games the past month, you can be inactive for a lot longer before your drop of the charts than when you have played 20 games in the past month.

While I prefer to have a system like FICS, I think this new system (dropping of the charts if you haven't finished a game in the past 6 months) is better than the old one.

tycho: Have a look at your Profile, Finished Games tab. The only difference is in the Position column, where some values are replaced by "-". Nothing else changes.

tycho: Who's talking about erasing some scores? Nothing is being erased, BKRs stay as they are, only some of them don't appear on the chart pages.

Are the red things on our profiles the games we have to play in to get back on the ratings chart?

Dear Fencer,

They are some reactions on the French speaking forum concerning the removal of "inactive players". It appears quite brutal (it should have been annouced in order to allow us to reactivate some games). The period of 6 months appears short (they are so many games and we appreciate very much brainking for that).

Would it be possible NOT to clear the BKR of so-called inactive players (I was disappointed to notice that my BKR for Janus chess is now unknow). I understand that the display of ranking could not take into account inactive players (it is not a bad idea, I agree) but erasing previous scores is a bit brutal, I think!

Finally, rankings are not so important and will not affect my pleasure on brainking.com!

The majoirty of my ratings either stayed teh same or went down :'(

Chessmaster1000: 1) I don't want to start a fight here. 2) Because some games had been restored in the past and the BKR was calculated twice for them, so the results were not accurate. Now they are.

For example my Dark Chess rating WAS ~ 1550.
Now it IS ~1950.
I can't understand why????????????

1)OK don't challenge your superiority of decisions, i'm just curious to see the reason behind your decision.......Can you give it to me please.......?

2)But a recalculation of the BKRs should have the same results for any number of times this recalculation will be done. I mean if now you re-recalculate the BKRs then we should have the SAME EXACT results for every player, excluding the players had a 2700. So for me for example, that didn't hit any 2700 BKR, my BKR should stay the same. But this happens if and only if the recalculation has been made only with the change for the 2700 limit. But since my BKRs changed, then something other must changed on the process of the calculation of the BKRs. Did you changed anything else......?

Fencer: That's good. Thanks.

reza: Well, I can add a switch to include inactive players on the chart pages.

Chessmaster1000: 1) Because I wanted to. 2) Because I recalculated all BKRs from the beginning, just to reflect this change.

Chessmaster1000: And where did the inactive players go to?

Isn't there a way to see them too?

2 Questions:

1)Since Ed Trice is the inventor of Gothic Chess and since you include the other inventors of the games, why you removed his name........?

2)My rating on some games increased and on some decreased and as PlayBunny said this happened to him too. And you said that this is because the 2700 limit has been removed. But i can't see how this affects in any way the ratings! Except the cases when a player had a 2700 and stayed there after winning some games-but that doesn't happened in any of my games or PlayBunny's. So....

AbigailII: The former is correct. Only the time of the last finished rated game counts, nothing else.
