    From Mark Crowther, The Week in Chess – a retweet of !ITUUR (see below)

    Only possible from the fantastic Alatortsev line in the Botvinnik (1.Nf3 Nf6 2.c4 e6 3.Nc3 d5 4.d4 c6 5.Bg5 dxc4 6.e4 b5 7.e5 h6 8.Bh4 g5 9.Nxg5 Nd5). Five queens on the board in Malisauskas-Vicas, Liepaja 2018, 42...Qe4+? gave a draw 42...Qbf4+ instead leads to mate

      Speed Chess with Nepo and Sasha

      On August 7, 2018 Ian Nepomniachtchi and Alexander Grischuk played a speed chess match on chess.com.

      The match format:

      90 minutes of 5/1 blitz
      60 minutes of 3/1 blitz
      30 minutes of 1/1 bullet

      With 3-minute breaks between segments

      Winner gets $1000 and advances to round two of the SCC

      https://www.chess.com/article/view/h...pionship-today

      ___________

      Sasha won the match by 17.5 to 11.5

      Two games from the match:

      The spectacular game eight made Nepo mad: "I lost on time [in] the game where I have had a forced checkmate." Objectively, the endgame was won for him, but there was no forced checkmate, although Nepo spent his last seconds looking for it. An opposite outcome could have driven Grischuk mad, whose advantage in the opening was overwhelming

      Nepo got in a psychological trap spending his last seconds to find a forced checkmate with a bishop and two rooks, but such checkmate does not exist

      ___________

      When the score left Nepo no hope to catch up and Grischuk was in no danger to be overrun, Nepo won two games out of the final three, slightly improving the overall result.

      Game 27, where the black king hid behind triple pawns, was the funniest.

        • Wei Yi showcases his skills in the last 3 games of the match where he wins by dominating in the opening, the middlegames (nice king hunt game 3) and zugzwang in the endgame in game 4.

            • Looks like he knows how to win this one, 3 in a row is a good effort!
            • It was a great ending technique, great calculations by Wei Yi
            • Approaching Lucena position
            • They aren't going for quick draws, or chickening out with repetitions, isn't that great?

              Double Queen Sacrifice

              GM Hovhannes Gabuzyan (ARM) won the Masters section of the 7th Annual Washington International by a full point. The Masters section, with 71 total players, included 22 GMS and 15 IMs. Gabuzyan moved into sole first place after winning his first four games. After that, no one could catch him, and he finished with a final score of 7.5 out of 9, earning the first place prize of $4500. Gabuzyan’s most interesting game was his second round win over GM Gil Popilski. You don’t often see a player sacrifice a queen twice in one game and win!

                The Chess.com Speed Chess Championship is taking place July 24th to October 18th 2018. 16 players in a knockout online blitz tournament. 90 minutes of 5/1 blitz, 60 minutes of 3/1 blitz, and 30 minutes of 1/1 bullet chess. Players: Fabiano Caruana, Shakhriyar Mamedyarov, Hikaru Nakamura, Wesley So, Maxime Vachier-Lagrave, Ian Nepomniachtchi, Levon Aronian, Wei Yi, Anish Giri, Alexander Grischuk, Sergey Karjakin, Hou Yifan, Jan-Krzysztof Duda, Vidit Gujrath were all invited.

                Two of the headlines from chess.com

                Speed Chess Shock: Duda Upsets Karjakin 13.0 - 11.0

                Jan-Krzysztof Duda played Russian roulette against Sergey Karjakin in the "bullet" portion of the Speed Chess Championship and lived to tell the tale. Duda not only survived the bullet segment, but won +4 =1 -2 to complete the upset.

                After going into the final discipline tied, Duda's four late wins propelled him to victory in what was widely regarded as the largest upset in the SCC's three-year history. It was unequivocally the biggest surprise in terms of ranking: a 14-seed taking out a 3-seed.

                Duda Upsets Grischuk In Epic Speed Chess Match 14.0 - 13.0

                Eliminating another Russian top grandmaster, Jan-Krzystof Duda became the first player to advance to the semifinals of the Chess.com Speed Chess Championship. The Polish player defeated Alexander Grischuk in a truly epic match on Tuesday.

                Duda's win against Sergey Karjakin was a huge upset, and to kick out another former world blitz champion of Russia is extremely impressive. The 20-year-old Polish grandmaster is quickly becoming a fan favorite, not just because of his results, but also because of his style. Yet again, hardly any draws were played yesterday. (Although, for that, it takes two to tango!).

                Peter Doggers at:

                https://www.chess.com/news/view/duda...ed-chess-match


                Wikipedia - Jan-Krzysztof Duda (born 26 April 1998) is a Polish chess grandmaster. A chess prodigy, he achieved his grandmaster title in 2013 at the age of 15 years and 21 days.

                  From chess.com

                  Stockfish Leads 8 Engines In Computer Chess Championship Stage 2; Lc0 A Contender

                  The first stage of the first Computer Chess Championship event is in the books, and after 562 official games Stockfish tops the leaderboard with an excellent score of 39/46, the first of eight engines to advance to stage two.

                  The two other big-name engines, Komodo (38/46) and Houdini (37/46), are just below Stockfish at the end of the stage one, with a large gap between those three and the next five engines in the standings.

                  The machine-learning chess project Lc0 ("Leela") finished in a solid fifth place with 32.5/46, good enough to advance to the next round as the neural-network engine wows fans with its intuitive and energetic play.

                  Created just eight months ago, Lc0 has improved rapidly enough to stake a claim as one of the world's top five chess engines —and it's not done gaining strength.

                  https://www.chess.com/news/view/stoc...c0-a-contender

                  What was the best game of stage one? Many Leela fans would choose Lc0's demolition of the Crafty engine from late in the stage. Leela's early Rxg7 sacrifice was both beautiful and pragmatic.

                  A reader also said this: Leela's game against Shredder as white was amazing, sacrificing the rook for a knight to gain a huge advantage (with no clear compensation to begin with, but it was definitely winning).

                  Both games are heregiven:

                  Position after White sacrifices rook for knight with 24.Rxc5!!






                  The iczero blog says this about that move:

                  Amazing Leela! She played that move with a +0.98 score while Shredder as also Stockfish afterwards in analysis are sleeping and say 0.00. Not judging from this game but generally, Leela’s eval is so much superior to all other engines, Stockfish included, that in some position shine so much, like here. She knows this must be winning. But it’s not. The drawing line though, is very hard to find and one has to dig incredibly deep to dismiss countless other moves that seem to hold but in fact are losing for just one tempo most of the times. But there is a line that seems to lead to a draw. But judging for over the board play, in real game time play, the moves deserves 2 exclamation marks for creating a situation impossible not just for Shredder, but for most engines or humans to handle over the board since white is winning in most variations creating startling zugzwang situations. Yet the real result must be drawn.

                  • Games from Recent Events

                    January 8, 2019

                    The Bay Area International took place January 1 to 7 in San Francisco/Burlingame, California and was won by GM Le Quang Liem.

                    Mike Klein – “It's not often that the winners get overshadowed, but that may just be what happened in Northern California this week. Long before the excitement of the final round, there was that loss by the eventual winner to the pre-teen FM Christopher Yoo in round three. This appears to make Yoo the youngest player ever to defeat a 2700 in a classical game (even younger than now-GM Rameshbabu Praggnanandhaa was in beating GM David Howell in 2017).

                    Yoo, playing in his home state, has taken advantage of the friendly confines of California. His second IM norm came just last year in Berkeley, also in the Bay Area. He earned his first in the 2017 North American Youth Championship, so that's the needed trio.

                    As far as crossing 2400, Yoo did that late in 2018 on several FIDE rating lists, so that appears to make him the youngest IM in American history. With a birthday of December 19, 2006, he's only barely 12 years old.”

                      Position after White’s 59.Rd1?

                      

                      - It is not easy to see 59.Rxf6, Nxe1 exchange sacrifice if last seconds on you clock are ticking. Nevertheless, even natural move with hand Re2 would have given white a chance to escape
                      - F A N T A S T I C O
                      - maybe this isn't quite a "masterpiece," but it's an extraordinary game in practical terms.
                      - The great Vladimir Kramnik comes at Caruana with four connected passed pawns... but somehow, Caruana ends up with the upper hand, and wins.

                      Vladimir Kramnik defeated Levon Aronian in brilliant style today at the FIDE Candidates' Tournament in Berlin, and in a Berlin. This time as Black, he played an early ...Rg8 and ...g7-g5 and just blew his opponent away.

                      It doesn't happen very often that Chess.com publishes a "flash report" of a tournament before the round has even finished. Today was one of those days.

                      It wasn't just Vladimir Kramnik's obliterating win over Levon Aronian that prompted us to publish it right away on our site—it was the way Kramnik played this game that was truly enjoyable for just about any chess fan on the planet, except Aronian and his dearest fans.

                      The brilliancy, a strong first candidate for Game of the Year, was widely praised in the Twittersphere, but also by one of the participants. "One of the greatest games I have seen. Amazing from start to finish, absolutely unbelievable," said Alexander Grischuk—and he has seen a game or two in his life.

                      - Bravo, Tiger! 30.Kf4!! and the mating King march to h6 is reminiscent of the 1991 Short-Timman brilliancy. But Tiger adds a Q sac. If 34...fxg6 35.Re7+ Kg8 36.Bd5+ Rf7 37.Re8+ Kg7 38.Rxf7 mate. One for every chess anthology.

                      • What a thrilling game. After time-control Aronian might hope for a miracle...
                      • What a game by Mamedyarov. Bxg2 must have come as a nasty shock to Aronian.
                      • "It was the top board clash between two of the strongest teams at the Batumi Olympiad 2018 - Azerbaijan and Armenia. Both the teams are well matched and their rivalry goes beyond chess board.
                      - In this crunch situation it was Azerbaijan who came out on top thanks to the victories of Mamedyarov against Aronian and Radjabov against Sargissian. In this video we capture the final moments of Aronian's dejection at losing the game and also Radjabov's final handshake to win the match! A great moment for Azerbaijan fans."
