Key to Chess Leagues scoreboard

Sort:

Most entries in the scoreboard at http://chessleagues.com/2015/wl/ are clear to me, but there are some that I don't understand. For example, what do the small numbers to the left and to the right of the match score mean? Take the match Germany - Holland in the first round of the WL 2015. Germany has "-3.0" and Holland "3.0" (apparently these numbers add up to zero). What's the meaning of this?

I got the answer to my question in another forum (Chess Team Holland). If a player wins a game, but later his account is closed because of cheating, the team result is corrected. The team of this player loses one point ("-1.0") and the other team's score is increased by one ("1.0"). -- If, by contrast, the account is closed during the game, the player loses the game by timeout and no correction is necessary.

Another question: How is the tiebreak in the WL calculated? I would have expected some Sonneborn-Berger (or Neustadtl) score (see Wikipedia), but -- as far as I can see -- the scores in the "Tiebreak" column of the WL page cannot be reproduced using the SB method.

@Oyvind: Thanks for the hint. This makes sense. I checked it for my own team, Holland, and it nicely adds up. Still a strange way to calculate SB. In proper SB the combination of "score = 0" and "tiebreak > 0" (which I stumbled upon) would be impossible.

As I understood the match result correction for closed accounts in the WL, it must always be symmetrical. That is, if Team A gets a correction of "+x", the opposing team B must get the correction "-x".

At the moment, this is nog always the case. For example, in the match Germany - Holland in Round 1 of the WL, Division A, the corrections are "-3,5" for Germany and "-0,5" for Holland. Is this a programming error? Or has something changed in the rules for corrections?

If the TB is not working correctly, (previously not now) that's because for all those matches that are not started, the score was considered as draw....

Yeah there's an issue with score adjustments at the moment that needs to be fixed.

I observed some of these problems myself. It's quite confusing atm. I hope will be solved soon enough.

In some matches, for example a match between Israel and Bangladesh

http://chessleagues.com/2015/wl/d/team-israel/

There appear to be matches with no players, in which one team is declared the winner. How do such things come about?

According to what I can see, it is appeared to have Bangladesh declared as the winner and Israel is forfeited. 

If you see, the table shows 1-0 in favor of Bangladesh. This usually happens when a team is lost by forfeiture

What does "a loss by forfeiture mean?"

Loss by forfeiture means that your team lost a match by default. For example (I don't know the reason of your case), but mainly because a match is NOT started on time.

That means let's say the match supposed to be started in Sept 15th and min number of players at your division (if I am not mistaken is 25, rigt ?) so in that case, if your team do NOT bring 25 players before the start time, BUT your opponent does, then according to the rules, your opponent will be annunced as the winner. 

So, I guess in your match against Bangladesh and Albania the same issue might have happened. Becaue I can see that your match against Albania is also being declared as 1-0 in favor of Albania. I suspect your team didn't meet the min number of players before the start date in those matches

Thanks. I'm new as an admin, and so I don't know the background to the current situation. As for the European League, how many teams in each division are kicked down at the end of each year?

robert8867

You're welcome. I have no idea about EL since I am not involved in administrative part of that League. I can only advise on World League and Asian League.

Good Luck

Danst7

Thanks. How does it work in the Asian league?

  • The top two teams from each lower division will move to the next highest division, and the bottom two teams from Premier and Division One will move to the next lowest division for the following year. So as to have a better spread of teams across the three divisions, one or more additional teams may also be promoted or demoted, as decided by the AL Management.
