yes, as most ohters here i tend to go up or down 8 with a win or a loss, or +1 with a player rankesd a lot lower than me, and tend to either get -11 or -14 for a loss agianst a player rated quite a bit lower than me

So if I am understand all the explanations then game count affects it as much as the win/loss!

I'll try thr formula too Pedro, thanks!

I won 13 straight from 21 Feb to 3 Mar and my rating improved dramatically.

Ok I created a spreadsheet using that formula and get:

Grenv: old BKR = 2332, new BKR = 2336 (+4)
BackgammonLover: old BKR = 2126, new BKR = 2118 (-8)

and that's correct...use this formula to calculate you ratings and compare them with those the system sends you after you fininsh particular games

http://math.bu.edu/people/mg/ratings/approx/approx.html

my point is I always seem to go up 8. I realize my opp went donw more because of fewer games played.

grenv:

grenv - Backgammon 468 1 381
BackgammonLover - Backgammon 18 0 6

for example:

You are the winner.

grenv: old BKR = 2332, new BKR = 2340 (+8)
BackgammonLover: old BKR = 2126, new BKR = 2109 (-17)

Game type: Backgammon

grenv: Just keep winning and it's not a problem lol

Yes, +-8 seems to be normal for me too. I'm not completely satisfied with the rating system, but i can't put my finger on exactly what it is.

ClayNashvilleTn: The match will be a draw then. And BKR will be calculated accordingly (BKR is only updated at the end of the match and it will be updates considering a draw). So, since a lower ranked player managed to draw against you, you'll probably loose some points while he'll gain some...

Having a fairly high ranking at the moment, I find that most wins are worth either +8 or +1 to me,, with the dividing line somewhere around 400 points differential. Nothing in between. If the differential is even higher, I may get 0.
Losses are a minimum of -8, and may go as high as -25 or more. So - against the majority of opponents, I have to win 8 out of 9 just to breakeven!

it seems like this doesn't apply to players with very established rankings. I frequently split games with players rated 100s lower with no effect.

Chances are, yes. You (higher ranked player) will lose more points on the lost game (to a lower ranked player) then you will gain winning a game (against a lower ranked player)

If I play an opponent and his score is 1600 and mine is 2000 and he wins one and I win one of a two game match will my score be affected?

I just sent all three of vaiza's blots to the bar in one turn in Hyper Backgammon and I did it coming off the bar myself. Has anyone else ever had this happen? I also happen to have a point guarded in my home base, so it is possible that those blots could stay there for a turn or two.

ah! so after black moves it continues to the next round and then decides if its over .. after white moves the turn goes to black .. and the server decides if it was the last move :)

Well, I've noticed that the "number of moves" shown for each game listed on a player's profile is one ply longer than the actual game. For example, here we see that the two reversi games between Hrqls and Nomad were 20 and 18 moves, while they really were 19 and 18. Whenever black is the last to move, a profile shows the game at an incorrect length. I think it's been this way since BrainKing 2.0.

the one that pgt posted has 35 moves but shows as 36 as well ? what is this extra move ? (the first roll of the dice ?)

Are we counting the number of moves until the game is 100% decided, or are we counting the extra moves after that as well? Not that I have any candidates either way.

37 moves: http://brainking.com/game/ArchivedGame?g=675119
Look at yours again grenv: only 36.

pgt: But the one I found is 37 moves. Where you playing for second place again?

I remember searching through many profiles some months age trying to find the longest game of Gothic Chess. It would be nice for information like that (maybe average game length as well? :-)) to be stated in the Statistics section or under each game's rules section.

http://brainking.com/game/ArchivedGame?g=702081
36 moves

Bry: http://brainking.com/game/ArchivedGame?g=640929
5 moves

Of course my finding is not absolute, I was hoping others would post games that are both longer and shorter.
In theory a game could be 3 moves. That would be frustrating for the loser, but it should happen here soon given the number of games being played.

I just looked at a couple of players who have played hundreds of games and clicked on Hypergammon in their profile. The game list includes the number of moves.

I know it's tempting to think that a technical solution is the only way, but sometimes good old brainpower and elbow grease does the trick.

"A quick search"????? Is there any search option for such a thing...........?

A quick search turned up:
http://brainking.com/game/ArchivedGame?g=611535 (37 moves)

My quickest: Here's me winning and losing on the 6th move:

What's the longest recorded game of Hyper BG there has been so far?

Blackadder Mr K: Thanks!!!!!!!!!

Zorro:
The first line under the players namn says Game ID.
Mail that number to Fencer and explain the case.

I just let a game time out on me! My opponent Pbarb is willing to have it reinstaed! What do I do next? I do not see a game number! Shen mentioned referring the game # to Fencer?

wayney:
It does happend that people stop playing at a site and it happends to that people can keep they high rankings a long time ( I wonder why I can`t )and there isn`t anything wrong with that,but I do think that somebody should take a look at this problem before it gets to hard to stop.
Has anyone told Fencer about this ?

Vikings: I didn't say I cared. I just thought it was interesting.

wayney: who cares, she hasn't played here in 18 months and only has a provisional rating, its meaningless

In looking at some of the top ranked players , I noticed claifornia girl had only played 4 games.
Having such a high rating isn't so abnormal, yet it makes one stop and think something fishy is going on when they receive a resignation such as this.

thanks

wayney: hi and welcome to Brainking. It's the best site around. Best of luck with all your games :)

I just joined this site to play some backgammon. I was referred here from another games site and I will be putting some games in the waiting room so if you care for a game, please join up thanks.

It may not even be other people helping him/her, it could be their own multi-nics...
I agree, this person should definitely be removed!

well I see that he has at least two legit games

lol .. shhh chuck ... dont yell too loud .. fencer might hear you ;)

nice digging bbw :)

TAINTED?
A LITTLE FALSE????

You guys are generous..... That person should be removed from this site and anyone who helped them cheat their ratings as well!!!!!

if they time out within 2 moves, it's not counted for BKR, but otherwise a win or a timeout have the same effect on the ratings.

I always wondered something about the ratings on here. Say someone timed out and lost the game instead of playing the game out. Is there any way the points would be different by time out over playing the game out and losing that way? How about in the winning player situation can they get more points for getting the win by time out over by actually beating the opponent?

yes i agree with both, and would say the ratings is a little false.

Beraun: I agree with Hrqls - and when you see someone resign instead of win, and when you see moves that will not hurt the other player - I would suspect that the 160 out of 167 wins is a little tainted.

Beraun: hmm weird indeed ... and he played against a lot of the same people directly after another .. and the people he played against all played against the same people as well most of the time ..

Can a player winning 160 of 167 of Hyper Backgammon? Hammer1 can ?¿¿
