19-year-old GM Haik Martirosyan of Armenia won this month's Titled Tuesday tournament. With 888 titled players, including top GMs Fabiano Caruana, Ian Nepomniachtchi,Maxime Vachier-Lagrave, andHikaru Nakamura, it was by far the biggest edition ever held.

With many countries under a (partial) coronavirus lockdown, a high turnout for our Titled Tuesday events in April was expected. The participation of almost nine hundred players was a surprise nonetheless.

Admittedly, the whopping 888 participants in the late edition last Tuesday was partly related to a mishap with the early edition. That 585-player event, unfortunately, had to be canceled after four rounds due to server issues that were resolved in time for the second tournament.

If that second tournament proved one thing, it was that the problems were not related to the number of players! With three hundred extra participants and a few sighs of relief, this tournament ran smoothly.

Here's a nice win by GM Anish Giri from the early edition:

Because of the removal of the earlier tournament, the prize fund for the late edition was doubled to $2,200. This attracted a total of 170 GMs, 191 IMs, 273 FMs, 12 WGMs, 23 WIMs, 17 WFMs, 67 CMs, 14 WCMs and 121 NMs.

BesidesCaruana, Nepomniachtchi, Vachier-Lagrave, Giri, and Nakamura, the list of famous names also included e.g. GMs Shakhriyar Mamedyarov, Vladislav Artemiev, Leinier Dominguez, Parham Maghsoodloo, Jorden van Foreest, Le Quang Liem, Nihal Sarin, andAlexandra Kosteniuk. Regular commentators such as GM Robert Hess and IM Daniel Rensch couldn't resist playing either.

Among quite a few participants who were streaming while playing was Nakamura. The American speed demon reached 5/5 thanks to this quick win over his compatriot GM Jeffery Xiong:

Nakamura's stream of the tournament.

A crucial game in the tournament was Nakamura's clash with Martirosyan in the penultimate round. It was a Fianchetto King's Indian where it was White who got a winning attack when his light-squared bishop started dominating the position.

Martirosyan managed to stay half a point ahead of the pack as he held world championship candidate Nepomniachtchi to a draw in the final round. In fact, it was Nepo who held the draw after not getting enough compensation for a sacrificed pawn:

Among the players trailing the winner by half a point was Caruana. The world number-two was in pretty good shape and won eight games, but he stumbled in round four against the Lithuanian IM Tomas Laurusas who confused him in the opening:

Martyrosian won the $1,000 first prize for finishing clear first with 8.5/9. Caruana shared second place withGMs Aryan Tari, Zaven Andriasian, Grigoriy Oparin, Daniil Lintchevski, IM Serg Zavgorodniy, and FM Irakli Akhvlediani. All won $142.86.

Nepomniachtchiwon the Chess.com streamers' prize of $200 which was given as 40 gifted subs to his channel.

A Message from the Executive Director - uschess.org

Making an appearance inLex Fridman's Artificial Intelligence Podcast, DeepMind'sDavid Silver gave lots of insights into the history of AlphaGo and AlphaZero and deep reinforcement learning in general.

Today, the finals of the Chess.com Computer Chess Championship (CCC) start between Stockfish and Lc0 (Leela Chess Zero). It's a clash between a conventional chess engine that implements an advanced alphabeta search (Stockfish) and a neural-network based engine (Lc0).

One could say that Leela Chess Zero is the open-source version of DeepMind's AlphaZero, which controversially crushed Stockfish in a 100-game match (andthen repeated the feat).

Even a few years on, the basic concept behind engines like AlphaZero and Leela Zero is breathtaking: learning to play chess just by reinforcement learning from repeated self-play. This idea, and its meaning for the wider world, was discussed in episode 86 of Lex Fridman's Artificial Intelligence Podcast, where Fridman hadDeepMind'sDavid Silver as a guest.

Silver leads the reinforcement learning research group at DeepMind and was lead researcher on AlphaGo and AlphaZero, and he was the co-lead on AlphaStar and MuZero. He did a lot of important work in reinforcement learning, defined as how agents ought to take actions in an environment in order to maximize the notion of cumulative reward.

Silver explains: "The goal is clear: The agent has to take actions, those actions have some effect on the environment, and the environment gives back an observation to the agent saying: This is what you see or sense.One special thing it gives back is called the reward signal: how well it's doing in the environment. The reinforcement learning problem is to simply take actions over time so as to maximize that reward signal."

The first part of the podcast is mostly about the board game go and DeepMind's successful quest in building a system that can beat the best players in the worldsomething that had been achieved in many other board games much earlier, including chess. The story was also depicted in a motion picture.

While AlphaGo was still using human knowledge to some extent (in the form of patterns from games played by humans), the next step for DeepMind was to create a system that wasn't fed by such knowledge.Moving from go to chess, so from AlphaGo to AlphaZero, was an example of taking out initial knowledge and wanting to know how far you could go with self-play alone. The ultimate goal is to use algorithms in other systems and solve problems in the real world.

The first new version that was developed was a fully self-learning version of AlphaGo, without prior knowledge and with the same algorithm. It beat the originalAlphaGo 100-0.

It was then applied in chess (AlphaZero) and Japanese chess (shogi), and in both cases, it beat the best engines in the world.

"It worked out of the box. There's something beautiful about that principle. You can take an algorithm, and not twiddle anything, it just works," said Silver.

There's something beautiful about that principle. You can take an algorithm, and not twiddle anything, it just works.David Silver

In one of the most interesting parts of the podcast, Silver suggests that the (already incredibly strong) AlphaZero that crushed Stockfish can be even stronger and potentially crush its current version. To be fair, he starts by calling this a falsifiable hypothesis:

"If someone in the future was to take AlphaZero as an algorithm and run it with greater computational resources than we have available today, then I will predict that they would be able to beat the previous system 100-0. If they were then to do the same thing a couple of years later, that system would beat the previous system 100-0. That process would continue indefinitely throughout at least my human lifetime."

David Silver and Julian Schrittwieser in a photo from DeepMind's Twitter page prior to a Reddit AMA.

Earlier in the podcasts, Silver explained this mind-boggling idea of AlphaZero losing to a future generation that can benefit from bigger computer power and learn from itself even more:

"Whenever you have errors in a system, how can you remove all of these errors? The only way to address them in any complex system is to give the system the ability to correct its own errors. It must be able to correct them; it must be able to learn for itself when its doing something wrong and correct for it.And so it seems to me that the way to correct delusions was indeed to have more iterations of reinforcement learning. (...)

"Now if you take that same idea and trace it back all the way to the beginning, it should be able to take you from no knowledge, from a completely random starting point, all the way to the highest levels of knowledge that you can achieve in a domain."

There is already a new step for AlphaZero, which called MuZero. In this version, the algorithm, combined with tree-search, works without even learning the rules of a particular game. Perhaps unsurprisingly, it's performing superhumanly as well.

Why skip the step of feeding the rules? Because eventually DeepMind is working towards systems that can have meaning in the real world. And, as Silver notes, for that, we need toacknowledge that "The world is a really messy place, and no one gives us the rules."

Creator David Silver On AlphaZero's (Infinite?) Strength - Chess.com

While in theory, this attribute doesnt extend to smaller players defeating larger ones, the Crownes Chess Sets nesting ability is more a portability feature. Made from 3D printed metal, the chess pieces nest within one another, like a Russian Matryoshka doll. After nesting the pieces within one another, the two largest pieces (the king and queen) snap together magnetically, forming a compact collection of same-colored chess players. The player-groups come in a rather delightful matte anodized aluminum finish too, giving the chess set a premium look.

The Crownes Chess sets approach to gameplay sort of gets influenced by its nesting ability too. Given that pawns are fairly often the first to lose their lives in games of chess, their small design lets them easily nest within other players. The chess set comes with a checkered board, as customary, but also features a magnetic platform for the king and queen pieces that hold discarded players. Each platform can hold as many as 4 pawns stacked on top of each other, followed by 4 other larger pieces (the elephant, horse, knight, and then the royalty). During gameplay, discarded or defeated players can just be snapped magnetically onto these platforms for convenient side-storage, or for dramatic effect, can be absorbed by the opponent! When the games over, the 32 total pieces on both sides get docked into 4 groups of 8, which you then snap together and roll up into the flexible board!

SINGAPORE - Thirteen years after chess player Kevin Goh began his journey to reach the pinnacle of the game, his efforts finally came to fruition this month, when he became Singapores first male grandmaster in over two decades.

Only three Singaporeans have previously been named grandmaster by the International Chess Federation (Fide). It is the highest title a chess player can attain.

China-born duo Wu Shaobin and Zhang Zhong earned the title in 1998, before they became citizens, while Wong Meng Kong achieved the feat in 1999.

Goh, 36, told The Straits Times on Friday (April 10) he was driven by the will to prove that an amateur like him - he juggles a career as the chief financial officer of oncology company Lucence - could achieve it.

Out of about 1,700 players who attained grandmaster status, Goh estimates that only 20, including him, do not train full-time.

"The obstacles and hurdles you have to overcome before you get to grandmaster are extremely difficult... it's hard to put into words," he said.

"At one point of time, I was stuck at (the second-highest rank of) international master, and the gap was so big I thought I might never get to grandmaster."

To be a grandmaster, an international master must attain a high performance ranking at three events with at least three grandmaster opponents from the chess federations of three different countries, called "norms".

He must also reach 2,500 in the Elo ranking, the chess ranking system, which Goh did when he climbed to 2,501 on March 3 after defeating top Myanmarplayer Wynn Zaw Htun.

He had attained the rank of international master in 2007, and got his first two norms in 2011 and 2012.

But Goh took a year-long break from competitive chess in 2013 to focus on his career, a move he called a "huge mistake" to his grandmaster ambitions.

He lost momentum, and spent "lots of money and time taking leave from work" to travel the world competing in tournaments in search of the third norm and ranking points.

Goh recalled "painful moments" of coming close, only to choke, even breaking down in tears after one loss in Hungary.

Despite the setbacks, the seven-time national champion and three-time SEA Games bronze medallist kept plugging away and won his earned his third norm in June 2018. The ranking points earned from his recent win in Myanmar meant he fulfilled all the requirements, and he was officially recognised as a grandmaster by Fide on April 1.

Even though he has made history, Goh was modest about his achievements, considering himself "very normal... not much smarter than anybody else".

He also expressed his gratitude to his backers and supporters, like Ang Hao Yao, Mark Choong, cyber protection company Acronis, local charity the Trailblazer Foundation, and the NTU Alumni.

He wants to help guide up-and-coming local players climb the international rankings.

"If the Singapore Chess Federation are able to identify young, talented players, I would be very pleased if I could play a part in helping them grow," he said.

"I've made many mistakes over the years, and I feel I would be able to share my experience and give advice to them."

Chris Lim, president of Singapore Chess Federation said:"We have not had a home-grown chess grandmaster this century and Kevin has shown through his perseverance that even in an academically-oriented Singapore, you can still excel in sports.

"His attainment of the highest title in chess will be an inspiration to our younger players."

Goh is also hoping to use the attention from his newly-attained grandmaster status to help those whose livelihoods have been affected by the coronavirus pandemic, and plans to launch a #ChessAgainstCovid charity drive that will involve online events and programmes.

"The goal is to rally enough support from within the chess community and from friends and corporate sponsors to raise $100,000 for needy families to help them weather the storm," said Goh.

"Ultimately if I can do my part to achieve that goal, my grandmaster title will be even more special."

Dubai: Viswanathan Anand, former world champion and Indias chess icon, has encouraged everyone to bring out the positivity in them to combat the coronavirus pandemic.

Speaking to Gulf News from Germany, Anand stressed on the importance of playing a sport like chess to tide over the tough times. These are very trying times. Staying positive while staying home is most important. Chess is a game that helps a family bond and is something that can be played both online or on the board, he said.

Anand is stranded in Germany due to the global travel restrictions these days. He revealed that on April 11, he plans to give chess fans from around the world a chance to play top players and raise funds to combat the Covid-19 virus. On April 11, Indian chess players will try to do their bit in fund-raising while giving chess fans an opportunity to play and engage with us, the multiple world champion in all formats also added.

Anand, along with Indias men and women champions such Koneru Humpy, P. Harikrishna, B. Adhiban, Vidit Gujrathi and Dronavalli Harika are all gearing up to play against global chess fans and players (at UAE time 5 pm) on April 11 through the portal chess.com and generate money for Indias Prime Minister-Cares Fund. The registration of $25 will fetch one a chance to play any two of the six top Indian players while a game against Anand would require a minimum donation of $150.

Anand believes everyone should enjoy chess. Enjoy the game, play a lot and study the game well. The main thing is one has to enjoy the game. Then it turns out to be much easier.

During the many interactions with Anand in Dubai in the past, he has always stressed on the importance of mental strength and training. Practice a lot and there are no shortcuts. Wanting to learn more and keeping my curiosity high have been the two factors that helped me to do well.

He had also mentioned how the internet had promoted the game and why it was important to watch great players in action. Nowadays, a whole lot of matches are shown live on the internet. So anyone can follow it wherever it is held. One can also watch five games simultaneously on the net. When I think back, I find it hard to imagine how people followed the game many years back.

4/10/2020 Alireza Firouzja is 16 years old and with a rating of 2728 currently number 20 on the FIDE World Ranking List. Many people believe that he will soon challenge Magnus Carlsen for the world title. But for now, at the beginning of April, the two first met for an online blitz marathon match in which they played 194 bullet (1+0) games. And the winner was...

What do chess players like best? Playing chess, of course! And in the times of the coronavirus they play online. Thus, Magnus Carlsen and Alireza Firouzja met for an extended online bullet match and played almost 200 games with a time limit of 1 minute for the whole game no increment.

Magnus Carlsen is World Champion in classical chess, in rapid and in blitz. But Alireza Firouzja is also a ferociously strong blitz player and in the past he has successfully challenged Carlsen in a couple of bullet tournaments.

The 16-year-old also hold his own in their direct encounter. After 194 games Firouzja won the match 103-90. Both sides impressed with the speed and resourcefulness. Moreover, despite the short time limit the quality of the games was also quite high.

Under the heading "World Champion tastes the bullet" Daniel King shows two examples:

Firouzja and Carlsen battle it out in bullet marathon - Chessbase News

The chess world has not been spared from the ravages of COVID-19, the disease caused by the new coronavirus.

We havent lost any notable players (so far), but the world title Candidates Tournament in Yekaterinburg, Russia, was halted last month, and major events such as the 2020 Olympiad, the U.S. national championships and the World Open have been postponed or scrubbed.

But as the philosopher Homer Simpson once remarked of alcohol, for the chess player the game is both the cause of and the solution to all of lifes problems. Yes, the game can be a tough mistress, the source of frayed nerves, sleepless nights and bottomless self-mortification.

But chess in this period of quarantines and social distancing is also an endless source of solace and distraction. We can finally tackle the mountain of magazines and unread books on the shelf, starting for me with Jesus de la Villas 100 Endgames You Must Know. Online events and leagues are still thriving.

And for a chess writer, theres a vast storehouse of games, studies and oddities to fill a thousand columns a week.

For instance, I found todays entertaining game while tumbling down a viral rabbit hole at the fabulous Chess Archaeology website (ChessArch.com), reading clips from the columnist from a previous incarnation of The Washington Times (who also covered checkers and whist). The 1904 game, played at the long-gone Washington Chess Club at 12th Street Northwest, featured two D.C. city titleholders, F.N. Stacy and Russian-born, Spanish-American War vet Vladimir Sournin. This may be the first time the game has seen the light of day since that first publication 116 years ago.

The early part of this Petroff is a very modern handling of a very old opening. Whites 9. c3!? f5 9. c4!? is either a tempo-wasting two-step or an admirable ability to change course in the face of changed circumstances.

Whichever, after 15. Bc4 Qd6 16. a4 Rae8, White claims an edge given Blacks clumsy setup, but both sides get in their licks in the enterprising play that follows: 17. d5!? (h3 Bh5 18. Qd3, was worth a look, if only to tempt Black with 18Bxf3 19. Qxd4 Nxd4? 20. cxd4 Qxd4 21. Bb5! Qxa1 22. Bxe8 Rxe8 23. Qe2 Qxa4 24. Qe6, with a deadly e-file pin despite the three-pawn deficit) Bxf3 18. Qxf3 Ne5 19. Qe2 Nxc4? (Ng4! it never hurts to threaten checkmate 20. g3 Qg6 21. Qf3 Qh5, and Black seizes the initiative) 20. Qxc4 Bf6?! (Qc5 was the prudent choice) 21. Bf4 Be5 22. Qe2!, exposing Blacks back-rank vulnerability.

Sournin cedes the exchange, but its still a terrific fight after 22Bxf4 23. Qxe8 Bxh2+ (Rxe8?? 24. Rxe8+ wins on the spot) 24. Kh1 Bf4 25. Re6 (an intriguing position: both queens are attacked but neither technically is hanging) Qc5 26. Re7 Rg8?! (better was 26Kg8 27. Qd7 Qxc3 28. Qe6+ Kh8 29. Re1 Bd6 30. Re8 g6, with a long struggle still ahead) 27. Qf7, when Black still can fight on with 27h6! 28. Kg1 Bg3 29. Rf1 Bd6.

Instead, 27Qxf2? proves to be the losing move, though after 28. Re8 Qh4+ 29. Kg1 Bh2+ 30. Kf1, White no doubt was sweating a few bullets as his king faces a barrage of queen checks on the open board. Its finally over after 34. Kc4 b5+ 35. Kb3, when Black cant put off the crushing mate threat on g8.

One can also turn to the great logician and polymath Raymond Smullyan, who passed away in 2017, for some more enjoyable ways to pass the time at the chessboard these days. Smullyan reimagined Sherlock Holmes as a chess detective using his powers of deduction to solve chess mysteries, including this Schrodingers cat of a puzzler from todays diagram, where White is to play and mate in two moves.

Ingeniously, the way forward depends on the way we got here. If Black cant castle, the answer is the trivial 1. Ke6 and 2. g8=Q mate. But what if Black can castle?

Well, if Black can castle long, that must mean his last move must have been with the pawn, and must have beene7-e5. That, in turn, means White can take en passant and the solution is now 1. d5-e6 e.p. 0-0-0 (on any other Black king or rook move, 2. g8=Q is mate again) 2. b7 mate.Both solutions, Holmes/Smullyan noted, are correct, though neither can be right if the other one is.
