December Wrap-Up; By ACC President

ACC events continue to be a great value with lots of quality competition at every rating level. All of our events are $1-$9 per game. The club held its Holiday Party on Dec 23 and over 60 members participated - a good time was had by all! As part of the party, the ACC held the ACC Action tournament (3 rounds, G/30, d5) in which a field of 19 players competed. Oliver Kayende won clear first followed closely by a 3-way tie for 2nd (2.5/3). Even though this was a long month (5 club meetings) and over 50 players participated, the ACC Ladder (30/90, SD/60, d5), ended in a four-way between J. Custodio, O. Underwood, I. Turner and T. Moore (3/5). In the ACC Blitz tournament (5 double-swiss rounds, G/3 +2), 22 players fought over the board with Larry Gilden taking clear first (8/10) followed closely by Justin Paul (7.5/10). Due to church construction issues, the ACC Action Plus tournament was not held this month.

New format for Grand Chess Tour 2018; By Pein, Khodarkovsky, and Rich; ChessBase

The organizers of the Grand Chess Tour announced changes to the format for 2018, including a new format for next year's London Chess Classic. The traditional classical tournament will be replaced by a semi-final and final held in mid-December that will combine classical, rapid and blitz chess over six days. The change is being made to make the tour final more dynamic, accentuate the purpose of the GCT's "Universal Rating" system (combining all three disciplines) and avoid conflict with the World Championship which will be also held in London from November 9th to 28th.

The Tsar, Matilda and the Russian Chess Championship; By Macauley Peterson; ChessBase

If you are bored with the turn of events in London classic (with only two decisive games in five rounds), look into Russian "superfinal", where the clash between hungry young talents, seeking to make a name for themselves, and experienced players such as seven-time Russian Champion Peter Svidler. So far the tournament has created a lot of decisive and creative games, and dramatics moments to delight spectators and chess fans alike.

Google's AlphaZero Destroys Stockfish In 100-Game Match; By Mike Klein; Chess.com

Chess changed forever today. And maybe the rest of the world did, too. A little more than a year after AlphaGo sensationally won against the top Go player, the artificial-intelligence program AlphaZero has obliterated the highest-rated chess engine. Stockfish, which for most top players is their go-to preparation tool, and which won the 2016 TCEC Championship and the 2017 Chess.com Computer Chess Championship, didn't stand a chance. AlphaZero won the closed-door, 100-game match with 28 wins, 72 draws, and zero losses. Oh, and it took AlphaZero only four hours to "learn" chess. Sorry humans, you had a good run.

The future is here – AlphaZero learns chess; By Albert Silver; ChessBase

Imagine this: you tell a computer system how the pieces move — nothing more. Then you tell it to learn to play the game. And a day later — yes, just 24 hours — it has figured it out to the level that beats the strongest programs in the world convincingly! DeepMind, the company that recently created the strongest Go program in the world, turned its attention to chess, and came up with this spectacular result.

DeepMind’s AlphaZero crushes chess; By Colin McGourty; Chess24

20 years after DeepBlue defeated Garry Kasparov in a match, chess players have awoken to a new revolution. The AlphaZero algorithm developed by Google and DeepMind took just four hours of playing against itself to synthesise the chess knowledge of one and a half millennium and reach a level where it not only surpassed humans but crushed the reigning World Computer Champion Stockfish 28 wins to 0 in a 100-game match. All the brilliant stratagems and refinements that human programmers used to build chess engines have been outdone, and like Go players we can only marvel at a wholly new approach to the game.

November Wrap-Up; By ACC President

ACC events continue to be a great value with lots of quality competition at every rating level. All of our events are $1-$9 per game.

Most notably this month, the club held a Blindfold Simulultaneous Matchon November 11, 2017, with the widely recognized Blindfold King, GM Timur Gareyev. GM Gareyev was very generous to ACC with his time as he also gave a Small Group lesson to 11 players on October 4th and dropped by the Friday club meeting on October 6th for another impromptu lecture.

The GM is originally from Uzbekistan and has held the rank of the 3rd highest rated chess player in the US with a peak USCF rating of 2780. He is best known for his exceptional Blindfold Chess playing ability. Blindfold chess is where the player has no sight of the chess board or position of the pieces on the board. He broke the world record in number of opponents (48) for a blindfold simul in Las Vegas in December of last year.

He is also a very active and successful GM having won the recent Atlantic Open with final round wins over local players LM Andrew Samuelson, WIM Jennifer Yu and GM Sergey Erenberg. See more on this performance at this webpage on the US Chess Federation website. For the ACC event, GM Timur Gareyev discussed blindfold simuls and took general Q&A for about an hour before taking on all challengers in the Blindfold Simul match. Unlike most simuls where players move when the GM comes to their board, GM Gareyev remained blindfolded and exercising on a stationary bike while a "Mover" took care of making the physical moves for the GM on each board. In an unusual move, the GM played Black on all boards and, unlike normal simuls, all players were put on a clock instead of getting 3 "passes."

The GM's record in the 16 games played at ACC was 15 wins and 1 draw, which he gave to young Ronen Wilson. Ronen said, "It was an honor to play the Blindfold King. I felt really good that I was able to get a draw." Ronen's dad noted, "It was a rare and thrilling experience playing Timur - he is a great guy and a wonderful ambassador for Chess." The GM offered one other draw, to yours truly, but the offer was declined to see how the game unfolded (I lost on time). For my part, I was amazed how quickly the GM moved from move-to-move and board-to-board, as he averaged about 1-2 minutes on each move throughout the match. Game scores from the Simul can be found in the latest edition of the VA Chess Federation newsletter.

Separately, in a short month, due to the Turkey Day holiday, the ACC Ladder (30/90, SD/60, d5), only had about 45 players compete for the Ladder Prize with young newcomer Donovan Chong grabbing first place (3/3). In a field of 14 players in the ACC Action tournament (3 rounds, G/30, d5), Andrew Samuelson and Zachary Martin split first place (2.5/3) followed closely by 5 players a half point behind them (2/3). In the ACC Action-Plus tournament (5 rounds, G/45, d5) Andrew Samuelson tied with Larry Gilden (4/5) amongst low turnout with Yobo Chen and Sam Schenk tying for 3rd (3.5/5). In the U1700 section, Brian Tay tied for first with Barzin Badiee (4/5) followed by a 3-way tie for third place. Finally, with the truncated number of playing dates, the ACC Blitz tournament was not held in November.

Mamedyarov & Grischuk take final Candidates spots; By Colin McGourty; Chess24

Shakhriyar Mamedyarov and Alexander Grischuk have qualified for the 2018 Candidates Tournament after their rivals failed in their missions at the Palma de Mallorca Grand Prix. Both Maxime Vachier-Lagrave and Teimour Radjabov could ultimately have qualified with last-round wins, but Maxime went down in flames to Dmitry Jakovenko while Teimour inexplicably offered a draw in a playable position against Richard Rapport. Mamedyarov and Grischuk therefore join Aronian, Caruana, So, Kramnik, Ding Liren and Karjakin as contenders to be Magnus Carlsen’s next challenger.

Tari & Abdumalik 2017 World Junior Champions; By Colin McGourty; Chess24

October Wrap-Up; By ACC President

ACC events continue to be a great value with lots of quality competition at every rating level. All of our events are $1-$9 per game.

In big news, on Saturday November 11th, Timur will play a BlindFold Simul at the Arlington Chess Club - Claim Your Spot and Register Early! Come check this event out!

Timur is a Super-GM topping out at 2780 and currently in the high 2600s. He has made a name for himself by holding BlindFold Simuls and last December (2016), he set the world record for playing 48 opponents on the way to winning 35 of the games and drawing over half of the rest.

In the ACC Ladder (30/90, SD/60, d5), nearly 50 players competed for the Ladder Prize with young Tony Lin grabbing first place (3.5/5) a full point ahead of X. Jian and M. Hiban (2.5/5). Of the 12 players in the ACC Blitz tournament (5 double-rounds [10 games] at a G/3 +2 time control), Larry Gilden held off the opposition to win first place (7.5/10) a half point ahead of young Geoffrey Davis (7/10) and a full point ahead of 3-way tie for 3rd place. In the ACC Action tournament (3 rounds, G/30, d5), Ken Chieu has returned to ACC events after a long hiatus to start collecting wins including running the boards against 11 other players to secure 1st place (3/3) ahead of a 3-way tie for 2nd place (2/3) by A. Indusekar, V. Guzman and Richard A. Allen (also returning after a long hiatus). And finally, in the ACC Action-Plus tournament (5 rounds, G/45, d5) we had a super low turnout as only 28 players slogged it out with Andrew Samuelson sweeping the opposition (5/5) in the Premier section to finish a full point and a half ahead of Zack Martin and Jason Liang who tied for 2nd place. In the U1700 section, Andy Chang won clear first (4/5) a half point ahead of Steven Scala and Isaac Stevens who tied for 2nd place(3.5/5). All in all, a busy month in which fun was had by all!
