Titled Arena 8

The 8th Lichess Titled Arena!
Immagine

Early last September, IM Minh Le (mutdpro) won the 7th Lichess Titled Arena, can he defend his new crown this month? The next Titled Arena will take place on October 26th. The prize fund this month is $1125, since Magnus gave his 3rd prize back.

As is now tradition, the tournament will be preceded by a Warm Up Arena, open to all players on Lichess (with a minimum of 20 rated bullet games).
  
Bravo Caruana !
Bella partita. Mi è piaciuto innanzitutto l'ultimo terzo dello scontro in cui da una situazione apparentemente pari è riuscito a mettere sempre più in difficoltà la posizione del re del suo avversario. Aveva occasione di imboccare la strada di un finale con un pedone in vantaggio e lui invece ha preferito la parità di materiale con il gioco attivo dalla sua parte. Bello averlo visto giocare cosi.
Carlson lo sta aspettando in novembre. Io mi sono già sbilanciato... :-)
  
Sarà un bello scontro, a novembre...

Minh Le wins Titled Arena 7

Previous winner Carlsen finishes 3rd
Immagine

Vietnamese IM Minh Le (mutdpro) defeated a very strong field of 226 players to win the Lichess Titled Arena 7. Le opened up a lead of 10 points by the end of the tourney but the fighting for the final spots was fierce up until the final moments. Finishing second was Armenian GM Zaven Andriasian (Zaven_ChessMood) who had a very strong showing in his first Titled Arena. Finishing third was former Titled Arena Champion and current World Champion GM Magnus Carlsen, (ManWithAVan) who was running late and played the tournament from his phone .

Titled Arena 7

The 7th Lichess Titled Arena!

It's been a month since GM damnsaltythatsport (Magnus Carlsen) reclaimed the most important throne by winning the sixth Titled Arena, and now it's time for the next one! Since Magnus donated his prize back, the winner takes home $1000 this time! At fashionably late notice, the next Titled Arena will take place Friday, September 7th.
  
Ah tu dici che Caruana non ha possibilità? Io mi stavo un po' ricredendo, visti i risultati dei recenti tornei. Comunque vederemo :)

Vedere lo streaming di qualche commentatore, come ad es ChessNetwork, è impressionante, perché vedi come i GM capiscano al volo cose che io ci metto una settimana a intuire! =)

ah dimenticavo, Carlsen ha partecipato, solo che cambia account ogni volta...

Aggiungo che Carlsen (che sembra aver partecipato da un'auto o qualcosa del genere, secondo le leggende che circolano e quindi da un mobile/tablet, con i conseguenti problemi per un torneo bulle) è arrivato terzo!

Carlsen restores order in Lichess Titled Arena 6

Carlsen dominates
Immagine

GM Magnus Carlsen ("damnsaltythatsport") won his 5th Lichess Arena title by a comfortable 20-point margin. He gained revenge for a disappointing showing in the previous edition. Finishing second was GM Daniel Naroditsky ("RebeccaHarris"). Third was GM Oleksandr Bortnyk ("Night-King96"). Fourth was IM Vincent Rothuis, who is the only non-GM to consistently compete for a prize in these events. Fifth place, and the final prize, was won by a single point. GM Ashkat Chandra just barely edged out GM Andrew Tang who took his turn having a bad tournament after spectacularly conquering the field last time.

This Friday, July 13, a Horde match will take place at 18:00 UTC. The match will be contested between svenos, a French FM who has been rated as high as 2826 in Horde, and StubenFisch, a young chess player who is one of Horde’s most active (and perennial top 3!) players and probably the “face” of Horde. The match format will be as follows:

2x 15+10 4x 10+0 6x 5+0 10x 3+0 15x 1+2 5x 1+0

I just discovered this open source app on F-droid that might be easy to adapt to complement the Hubzilla Chess addon.

It's so cool to see this OpenWebAuth in action on something other than the Hubzilla webpages in a browser! I can log in to my channel's primary hub with username/password, then use the /rmagic endpoint of a remote hub to seamlessly authenticate to that remote hub and subsequently access private content (in this case a chess game history where I'm the player whose channel lives on an independent hub).

@Mike Macgirvin the response to a successful remote authentication via /rmagic is HTML text whether the auth succeeds or fails, and a session cookie is obtained in either case too. Is there a way to get a JSON response with a true/false message of some kind? I actually did this already in the chess addon, where I created a chess/login endpoint for the local channel so that I could return a JSON success status. To do this I duplicated and simplified the include/auth.php code. This is obviously not ideal and I'm probably missing an existing endpoint.

// API: /chess/login // Authenticate to hub case 'login': require_once('include/auth.php'); $verify = account_verify_password($_POST['username'], $_POST['password']); if ($verify && $verify['account']) { $channel = $verify['channel']; $account = App::$account = $verify['account']; $_SESSION['account_id'] = App::$account['account_id']; $_SESSION['remember_me'] = 1; App::$session->new_cookie(31449600); // one year $_SESSION['last_login_date'] = datetime_convert(); authenticate_success($account, $channel); json_return_and_die(array('status' => true)); } else { json_return_and_die(array('errormsg' => 'Authentication failed', 'status' => false)); }
  
I don't know exactly what you're trying to do so I don't have a good answer. If I was in that situation I would try to re-use the existing login code, because include/auth.php already processed the login and there's no need to do it twice. Basically if $_POST['auth-params'] === 'login' , somebody tried to login (this is handled by the system long before calling your module); and if local_channel() is false, they failed.
  
You're right. I should be able to just check if local_channel() returns true in the chess/login endpoint function and return that boolean in the JSON format the Android app needs. I don't know what I was thinking.

I will still encounter a similar situation when using /rmagic or /magic for remote auth, because the app will receive a response body in HTML format and a header including a session ID regardless of the success or failure of the authentication attempt. Perhaps I could add a check for a request header specifying return content type JSON to the /magic class?
