Chess-Series

Chess Series almost finished
by @moistvonlipwig

The first season of the Chess Series is nearing completion.
In the Swiss section the winner is already decided, it‘s Assassin_in_White with a strong 8/8 score!
Following on places 2 and 3, tonychess75 and citronsauvage with 7 points each.
More detailed results in the next ledger, once all games are finished.

In the round robin groups there are still a couple of unplayed games so the winners aren‘t decided yet. In the Masters group the game MoistvonLipwig vs Fabinou, the clash between the first and the second of the current standings, will decide the top group of the Chess Series. Everyone is welcome to tune in and watch.

After the seasons finish on January 28th there will be a week break. On February 5th the registration for Season 2 will open. Until then the rules will be modified quite a bit to avoid some of problems that occured in the first season. If you have specific ideas for changes feel free to suggest them in the #series-general channel. (Though please understand that if suggestions have already been discussed at length before we aren‘t too motivated to discuss the same thing again.)We are looking for new mods for the Chess Series. If you think you would make a good mod, please contact @moistvonlipwig or @mastersalomon. Preferably from the US west coast or east Asia so that their availabilities complement those of us European mods.Furthermore we are looking for motivated web developers. During the break we would like to start to automate some of the things that so far had to be done manually. (chesster, possibly integration in the lichess4545 site etc.)
If you‘re interested in helping us with that, please join series-dev where we will post more details soon.

Team League Survey Results

by @somethingpretentious

It's nice to see we still have good satisfaction in the league. I won't go into any more detail here but we're very pleased too!

Congratulations to "I think, therefore I'm in time trouble", winners of the best team name vote with 17% of the vote. Honourable mentions to "The King Goes Skrra" (16%), "Make Luft Not War" (12%) and "We're OK with any name actually" (9%). Your team's name is possibly the most important part of the whole league, so don't procrastinate and start thinking up a good name right now!

As with previous seasons, the survey trends towards keeping many parts of the league the same. Rating balance preferred to team requests (76%), 6 players per team (77%), maintaining league size (76%), maintaining the season length (75%), and keeping one comprehensive league with no split (80%) are all similar to previous survey results.

81% percent of respondents enjoyed the mid season break over the holiday period, but it's split right down the middle for if we should take a break every season.

47% of people would like a video review of the games this season (34% no preference) - remember to nominate games for the video review by messaging @chesster in a DM "nomination 45" or by visiting https://www.lichess4545.com/team4545/season/10/nominate/ while logged in to the site.

Now for the new rule proposals. The results of games by players found to be cheating will remain as a full point reversal by popular demand (80%). Next season we will be allowing players to play *down* one board in cases where there is no alternate available or player to play up with permission from the opponent team based on 62% in favour. If no player can be found at all to replace a team mate, this result will remain a forfeit loss as it has been in previous seasons (61%).

Thanks to everyone filling out the new demographic portion of the survey:
58% Europe, 30% North America, 4% Asia, 3% Africa, 3% South America and 1% Oceania.

There's been some great feedback on the ledger as always, so thank you for that! Unfortunately it takes a lot of time and work to create, so if you want to see them more often and you have the time to help out, be sure to join #lichessledger. @tnan123 has had to take a back seat, and while @kraaft has taken up the mantle, more help is always appreciated!

The start of the next season was a close vote, but 12 February won out by 5% (40% "one week break" won over 35% "having no break at all" -- you chess addicts!). This means registration will open on the 29 January, with teams released on 5 February and the first round starting 12 February. As always, earlier registrations are given priority so set a reminder in your calendar now!

Chess Puzzle

@erinyu delights us with 10 entertaining tactical study :

And a new puzzle from Team(45+45) #10 round 4 on board 1 : samuelifowler vs moistvonlipwig
Black to move.

Hint (select to reveal) : The White Be5 is unprotected, how can Black exploit that ?

Solution (select to reveal) : Nf2. If white doesn't deal with it he will lose one of the bishops with check. If 19.Qxf2 however, he loses to 19...Qxe5+ 20.g3 Qxa1
