Deathmatch: Penguin vs. Paco

Nojoke Chess

Two Titans Battle it Out

This Saturday, May 12th 18:30 UTC, a match will take place between two of the best bullet players on Lichess. GM Paco Vallejo and GM Andrew Tang will put their chess skill and mouse speed to the test. They will play 12 games of 1+0 and 12 games of 2+0. The public will be able to watch both players in real time on their live streams and listen to their thought process (to the extent that fast chess allows).

GM Andrew Tang Wins Lichess Titled Arena 5

World Champion Magnus Carlsen's dominating winning streak comes to an end

On Star Wars Day, in the 5th event of its kind, we got to see 237 titled players, including 44 GMs, participate in two hours of bullet craziness. Would World Champion Magnus Carlsen continue his total domination of the Lichess Titled Arenas, or was it time for someone else to take home the jackpot first place prize of $3,000?

Magnus, the quadruple Titled Arena Champion, started the tournament livestreaming his participation on Twitch, but a suspicious internet connection quickly forced him to play the rest of the tournament without livestreaming. GM Andrew Tang (@penguingim1), who streams frequently, was also noticeably missing from Twitch, choosing not to stream in order to increase his chances of winning the event.

GM Andrew Tang Defends Humanity Against Leela Chess Zero

The new AI puts on an extremely strong performance against the human Grandmaster

As previously announced, on Sunday we got to see a historic match between GM Andrew Tang (@penguingim1) and the self-taught chess engine, Leela Chess Zero.

Historic because Leela is not a traditional chess engine. She learns and improves over time exclusively by playing chess against herself. This means she's free from human tendencies and limitations. Maybe it's possible for Leela to come up with new concepts, or combine existing chess principles in a new way? That's one of several reasons many people are excited about Leela.

Announcing Lichess Titled Arena 5

T. Alexander Lystad (@arex) Announcements

The Lichess Titled Arena returns with a $3,600 prize pool!

In April we hosted the Lichess Titled Arena 4 tournament. 218 titled participants, including 34 GMs, played for a total prize pool of $3,200. World Champion Magnus Carlsen overtook GM Andrew Tang towards the end of the tournament to win it in dramatic fashion. For the fourth time, Magnus decided to donate his first place prize back to Lichess for the next event.

Now we are announcing Lichess Titled Arena 5, which will take place on Friday, May 4th. Thanks to Magnus's generosity, and a $350 donation from an anonymous donor, the total prize pool for this event is $3,600, including the huge $3,000 first prize. There are prizes for the top five places.

GM Magnus Carlsen wins fourth consecutive Lichess Titled Arena

T. Alexander Lystad (@arex) Chess

The craziest finish yet

Lichess Titled Arena 4 set all kinds of new records. This time around we had 218 titled participants, including 34 GMs, playing bullet games against each other for 2 hours straight. Would World Champion Magnus Carlsen be able to defend his three-event long winning streak against this strong field?

An unknown GM account, @CleverTacticButFail, who was later revealed to be GM Andrew Tang, took the lead early on and held it for most of the tournament. At some point, GM Magnus Carlsen (@DrDrunkenstein) was more than 30 points behind the tournament leader. However, the last 30 minutes of the tournament turned into an insane comeback story that will be remembered for a very long time. Tang's nerves may have gotten in his way, or maybe he just got unlucky. In either case, he took a few losses and draws and was unable to maintain the valuable fire (winning streak). Magnus Carlsen, on his part, pulled off an incredible, and unheard of, 19-game winning streak to close the gap and finish the tournament 8 points ahead of Andrew Tang.
