How Teaching Kids Chess Will Benefit the U.S. – National Review

So argues John Mac Ghlionn in todays Martin Center article.

In chess, he writes, Every action has a reaction. Decisions have consequences. The game of chess teaches people basic life skills, like the importance of patience, perspective, and proper planning. It is, in many ways, a highly effective, highly instructive educational tool. Right now, the US is very much lacking such tools.

Thats right. Playing chess builds, to use Hercule Poirots favorite phrase, the little gray cells.

Ghlionn explains that, Researchers have found that the schema used by chess players is eerily similartothe scientific method, with great emphasis placed on calculations and assessments. Other researchers havedocumented the ways in which chess improvesattention, memory, concentration, and reasoning among players.

If American schools (including colleges) would encourage chess, that would have great benefits for the individuals and, in the long-run, for the country.

Make Your Move, March 2022 – Tactics III and IV – uschess.org

Make Your Movechess tactics appear monthly inChess Lifemagazine, an exclusive US Chess member benefit. Not a member? Join today!

This month's 9 puzzles are all taken from the 2021 World Rapid and Blitz Championships in Warsaw, Poland. The puzzles start from easy (1) and gradually move toward being difficult (9). Please note that "easy" is a relative term. Newer players will find the "easy" puzzles to also be a challenge.

First, try to solve the puzzle without checking the hint. If you cannot, open the hint to get a clue. Try your best to solve the puzzle completely on your own before checking the solution.

If you were unsuccessful, return to the puzzle in a few weeks to see if you can solve it. That way, you gradually expand your tactical vision and you'll be more likely to spot tactics when they occur in your own games.

Whatever you do, do not use an engine to solve the puzzles. You will only be cheating yourself out of improving your game.

I Played The Game Elon Musk Is Obsessed With So You Don’t Have To – Kotaku

Photo: Theo Wargo (Getty Images)

Last December, Grimes released a new song from her upcoming album Book 1. The track, called Player of Games, was speculated to be inspired by her relationship with Elon Musk. One of the lyrics, Im in love with the greatest gamer, got me thinking: what kind of video games does Musk play when hes not reinventing public transit or allegedly abusing his employees?

A recent Vanity Fair interview with Grimes revealed that Musks latest obsession is The Battle of Polytopia, which he describes as a much more complex version of chess. Apparently, hes even beaten the creator at his own game at least once, which hes very proud of. While hes obviously boasting about his big brain for his fawning fans, I wouldnt be a video game journalist if I didnt check out the game for myself. So, I downloaded Polytopia and played a single game.

The Battle of Polytopia is a civilization simulator in which you control one of twelve different tribes. You try to expand the territory of your empire by collecting resources, exploring uncharted territory, and destroying rival civilizations. In short, its the exact sort of game that might appeal to a white billionaire who benefitted from apartheid in South Africa. He loves it so much that at one point, Polytopia was added as a playable game to Tesla carsyou know, before the government started asking questions about a feature that might take your attention away from driving.

I played one game, which lasted twenty-five rounds. Every round, I could move my military units one space across the map, and I would be rewarded with stars each turn. These resources could be invested into extractive technologies for things like forestry or fishing, or they could be put into new kinds of soldiers. The goal was to wipe out as many enemy factions as possible before the turn limit.

Polytopia is not as complex as Musk described. If anything, winning against the computer-controlled enemies was easier than any chess game Ive ever played. There were more opponents than in a chess game, but its difficulty was inherently constrained by the number of possible actions per turn. Polytopia is an approachable game for newcomers to the civilization builder genre, but its definitely not what I expected from the so-called Player of Games.

Can a chess grandmaster save the world? – ChessBase

Iart Luca Shytaj

He was born in Albania (Tirana) in 1986. His parents moved to Italy when he was six years old and he became an Italian citizen in 2007.

Luca (as he is known to friends) is a very strong player whowon the Albanian Chess Championship in 2003 and represented Albania twice in Olympiads (Calvia 2004 and Turin 2006) and Italy once in an Olympiad (Dresden 2008 the picture above, by Cathy Rogers, was taken there) and once in a European Team Championship (Novi Sad 2009).

He won the Albanian Championship (2003), the Italian Rapid Championship (2009), and the Italian Team Championship in 2016 playing for the Fischer Chieti team.

Luca was awarded the title in October 2018, the 14th Italian player to achieve the title of GM.

In the scientific field Luca holds a master degree in Genetics and Molecular Biology (from the La Sapienza University in Rome). He obtained a PhD in Medical Microbiology, Immunology and Infectious Diseases, working on an HIV cure project under the supervision of Andrea Savarino. Later he performed his research at the Italian Institute of Health in Rome and at Heidelberg University in Germany. He is currently a visiting Professor at the Federal University of Sao Paulo in Brazil.

When I showed Luca the click-baittitle of my article, he asked me if I knew Betteridge's law, which states that "any headline that ends in a question mark can be answered by the word no". I definitely hope that this is not the case here. I have urged Luca to abandon his attempts to rearrange little pieces of wood on a checkered board slightly better than other people, and concentrate on the more urgent global tasks that need to be solved.

Luca and his team have been working on Cobicistat, a drug used in HIV/AIDS therapy, showing that it could have an effect against COVID-19. That is the result of a study, until now conducted only in vitro and in an animal model, published in the journal of the American Society of Microbiology, mBio.

The international team of authors proved thatCobicistat inhibits the replication of SARS-CoV-2 with a different mechanism from those of the drugs currently used, i.e. by blocking the fusion of the virus to its target cells. Furthermore, the drug can attenuate the progression of the disease in a hamster animal model (Mesocricetus auratus), by enhancing the effect of another drug previously tested against COVID, i.e. Remdesivir.

If you are interested in the details of the research, the article on COVID is now published and free to read:

Combinations of direct-acting antivirals are needed to minimize drug resistance mutations and stably suppress replication of RNA viruses.

Currently, there are limited therapeutic options against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and testing of a number of drug regimens has led to conflicting results.

Here, we show that cobicistat, which is an FDA-approved drug booster that blocks the activity of the drug-metabolizing proteins cytochrome P450-3As (CYP3As) and P-glycoprotein (P-gp), inhibits SARS-CoV-2 replication. Two independent cell-to-cell membrane fusion assays showed that the antiviral effect of cobicistat is exerted through inhibition of spike protein-mediated membrane fusion. In line with this, incubation with low-micromolar concentrations of cobicistat decreased viral replication in three different cell lines including cells of lung and gut origin.

When cobicistat was used in combination with remdesivir, a synergistic effect on the inhibition of viral replication was observed in cell lines and in a primary human colon organoid. This was consistent with the effects of cobicistat on two of its known targets, CYP3A4 and P-gp, the silencing of which boosted the in vitro antiviral activity of remdesivir in a cobicistat-like manner.

When administered in vivo to Syrian hamsters at a high dose, cobicistat decreased viral load and mitigated clinical progression. These data highlight cobicistat as a therapeutic candidate for treating SARS-CoV-2 infection and as a potential building block of combination therapies for COVID-19.

The joys of chess: The Romanian Blitz, Rapid and Solving Championships – ChessBase

This years edition saw all the strongest players in Romania, with a record number of titled players, but also young kids participating! Was it thanks to the increased prize fund, the Romanian Federations efforts to offer the best possible conditions for the players, or the increased media attention chess has started to get in Romania? From my perspective, all these factors played an important role and I feel proud of the Romanian Federations latest work to get chess the attention it deserves!

Before jumping to chess, Id like to take a moment to thank the president of our federation - Vlad Ardeleanu (CEO at Medima Health) for his passion for chess and for all his efforts (together with his young and enthusiastic team) for us, the players, to be proud to represent Romania at both the national and the international events! In his speech at the closing ceremony, Mr. Ardeleanu said that his approach was to be among the players, hear them out, and get a real feel about the challenges we face and thats exactly why he decided to participate in the Blitz Championship himself - an initiative I can only applaud!

Vlad Ardeleanu, President of the Romanian Chess Federation

Jumping to the chess part, the first dare was the Solving Championships - a discipline which I love and participate at every time I get the chance! It consists of 9 puzzles and one can get a maximum of 5 points for each - 2 mates in two moves, 2 mates in 3 moves, one mate in 4 moves, two studies, one self-mate and one help-mate, all to be solved in 120 minutes. Mate in 2, how come - should be easy, one would be compelled to think. But no! These are not straightforward mates, but rather crazy and irrational ones. Those of you knowing a bit about chess composition are probably familiar with the concept, but for those who hear about it for the first time, here are some positions which gave me quite a headache, thanks to one of the arbiters of the competition and the one in charge for our headaches at the National Solving Championships for many years now: IA Dinu-Ioan Nicula.

Mate in 3- position #4 at the Womens National Solving Championship

Solution: 1.Ne3 - 1.5p (threatening 2.Qf2+ - 0.5p)

1Ke4 2.Qd5+ -1.5p

1Kxg3 2.Qg2+ -1.5p

This one was a nightmare - I couldnt solve it and lost quite a lot of time and nerves on it, as I usually dont struggle so much in finding the mates in 2 and 3 and it was so frustrating not being able to find the solution

Another very tricky one was the help-mate, a task in which black starts and helps white to mate him in 2 moves. I could find only one of the two solutions - the first one. (the notation for help-mates is a bit different, as we use "1." for blacks first move rather than "1")

Helpmate

Solutions: 1.Bb3-Rd5 2.Bc2-Nd3# - 2.5p

1.f5-Rb3 2.Bf3- Rb6# -2.5p

Isnt it fascinating? I love how one can use ones imagination to think in a completely different way that is unusual for a professional chess player when solving this type of puzzles! I believe this was a very good training before the Rapid & Blitz and even if not all the titled players share my enthusiasm and prefer to keep their energy for the other disciplines - the competition at the solving tournament was fierce! Interestingly enough, a high rating is not a guarantee that someone is be good at solving. For example, I had 25.65 points out of 45, and with an Elo rating of 2390 I was the highest rated player in the event whereas Dariana-Gabriela Didiliuc, who finished second with 25.5 points, has only a rating of 1841 in classical chess! Third place went to WIM Silvia-Raluca Sgircea (2238 ELO).

Irina Bulmaga, Dariana-Gabriela Didiliuc, WIM Silvia-Raluca Sgircea

In the open section, the first two players both scored 34.5/45, but IM Mihnea Costachi finished first, as he used 119 minutes while GM Vlad Jianu used all his time (but only one minute more - 120 minutes). FM Marius-Nicolae Ceteras (long-time coach of IM Mihnea Costachi) came third with 32.5 points.

The Womens Rapid Championship was a tough competition, with all the members of the National Team present along with dangerous and quickly-progressing young players.

A future Romanian Champion?

At the end, it all came down to the last round. I was leading throughout the event and had 7.0/8 before the last game, and was one point of WGM Elena-Luminita Cosma, WCM Iselin-Amanda Lolici and IM Corina Peptan who all had 6.0/8.

I needed only a draw to secure first place, but I had to play with black against IM Corina Peptan, who probably has won more tournaments than any other female player in Romania. The first tie-break was the result between the tied players, so a loss would mean that I might lose the title. However, in case of a three-player tie the best Buchholz would count, and I probably would still be first as I had the best Buchholz before the round. Cosma quickly won against Lolici securing me a three-way tie should I lose against Peptan.

I got a good position against Peptan and a drawish endgame arose, but then I suddenly started to blunder all my pawns Did I relax too soon or was I already too tired? Who knows At a certain point, I just wanted to resign, but then decided to keep fighting until the end, even with 3 pawns down. When we had only seconds on our clocks, I managed to hold a draw in a position which reminded me of the Solving Championship

WGM Elena-Luminita Cosma came second with 7.0/9, while WGM Mihaela Sandu scored 6.5/9 and finished third on tie-break.

The Open Section saw an all-star field, with all the players of the National Team present along with other strong GMs and IMs, but here too, a lot of promising youngsters started.

A future Romanian Champion?

Before the last round, GM Constantin Lupulescu and his student IM David Gavrilescu were sharing first place with 7.0/8 each. Five players with 6.5/8 each followed half a point behind. Lupulescu drew his last round game with Black against Romanias number one GM Bogdan-Daniel Deac, but Gavrilescu, who also played with Black, managed to win against GM Marius Manolache and won the tournament with a fantastic score of 8.0/9!

IM David Gavrilescu

Lupulescu (who had the best tie-break), 16-year old CM Teodor-Cosmin Nedelcu, and IM Alexandru-Vasile David shared places two to four with 7.5/9 each.

The Blitz Championships followed on Sunday, starting at 9 am in the morning - the only thing I could criticize the organization for, as I believe many of us love our Sunday sleep, but, on the other hand, once the first game started and the adrenaline started to pump, we quickly forgot about the early hour!

In the Womens Section, IM Corina Peptan was leading throughout the event and finished first with an impressive score of 8.0/9. I believe the critical moment was our game in round 6. I had White and avoided a repetition but soon found myself in a completely lost position which Corina had no problems to win!

In round 8 Corina suffered her only loss in the tournament against Cosma, who in the end finished third with 7.0/9. I was a bit disappointed by my bad loss against Corina, but managed to pull myself together and won all my remaining games to finish second with 7.5/9.

The winners of the Women's Blitz Championship: (from left to right): IM Corina Peptan, IM Irina Bulmaga, WGM Elena-Luminata Cosma, WFM Alessia Ciolacu

In an interview after the tournament, Corina mentioned that this might be her last National Championship, as she felt like focusing on other things after a long and successful career. I hope she will change her mind and we will continue seeing her competing in the future as there are so many things one can learn from her - and Im not only talking about the chess qualities she has, but also about the fact that she is a very humble and kind person - qualities which our (chess) world desperately needs.

IM Corina Peptan

In the Open Blitz Championship, four players shared first, all scoring 7.5/9. Lupulescu had the best tie-break, followed by Deac, Jianu and GM Costica-Ciprian Nanu.

The winners of the Open Blitz Championship (from left to right): GM Bogdan-Daniel Deac, GM Constantin Lupulescu, GM Vlad Jianu, GM Ciprian Nanu, IM David Gavrilescu, GM Vladislav Nevednichy

Last, but not least, it was the first time the Romanian Blitz, Rapid and Solving Championships were covered live by a great media team, with commentary by WGM Sabina-Francesca Foisor and IM Vladimir Doncea. I was told they did a great job and many of our supporters had a great time following the action from their homes!

WGM Sabina-Francesca Foisor and IM Vladimir Doncea

After a weekend full of adrenaline and emotions, I would once again like to thank the organizing team for this celebration of chess and for the very fine job they did, for us, the players, who had the chance to enjoy the game and to give our best! Caissa smiled to some of us, but I hope she also inspired the many lovers of the game and young children to work on their chess, to demonstrate fair-play, be fierce, but also not to forget about being kind and humble!

Proud to be Romanian!
