    Prague Chess Festival 2019

    March 7, 2019

    The Masters is a 10-player round-robin tournament organized by Nový Bor Chess Club, taking place from 6-15 Marchin hotel Don Giovanni in Prague, Czech Republic. Players receive 90 minutes for 40 moves, followed by 30 minutes to the end of the game, with a 30-second increment starting from move one.

    All rounds start at 14:00 UTC

    From the official site:

    ROUND 1 REPORT

    The inaugural Prague International Chess Festival started today in Prague, with Masters and Challengers tournaments. Both events feature some of the strongest chess players in the World, as well as the best Czech players.
    The ticket to Masters event for the winner of Challengers group seems to be a big motivation for the players, as already at start of the tournament we had 4 decisive results in the B tournament.

    The first one to score was Polish GM Mateusz Bartel, who defeated Indian rising star R.Praggnanandhaa, and he went in history as the first winner of the Prague Chess Festival.

    Russian Grandmaster David Paravyan scored a nice attacking victory with White pieces, after his opponent Jiri Stocek mixed his prep and made mistake in the opening. In all Spanish derby between top two seeds of the event, the 23-year-old David Anton Guijarro celebrated a victory. After the game, he was very kind to share his impressions and thoughts about the game with the audience in the commentary room.

    Peter Michalik celebrated an important victory with Black pieces against his fellow countryman Jan Krejci, after making few good strategic decisions in the middle game. The only draw in Challengers group was agreed between young Czech star Thai Dai Van Nguyen and Women's World Champion Ju Wenjun in an equal Bishop endgame.

    In the Masters event the things were quite opposite. Four games ended with the peaceful result, although most of them were fighting draws. The only decisive result happened in the game Richard Rapport vs Jan-Krzysztof Duda. The young Polish Grandmaster, who is known for great speed chess performances, showed that he can do as well in the classical games too! The Hungarian had the edge after the opening, but he misplayed the position in the time trouble ended up with a piece down. Duda played precisely and kept his cool, to eventually win in 94 moves.

    David Navara didn't manage to convert his game against Boris Gelfand, even though he had a very promising position. The game was opened with Petroff, and after several moves it was clear that Czech #1 was confident with his home preparation, as he was playing fast, leaving Gelfand much behind on clock. Navara sacrificed the exchange, and forced the Israeli player to give up his Queen, however it was not enough for a full point, and the draw was made in 100 moves.

            “13-year old Praggnanandhaa is one of a generation of Asian kids who may dominate chess in a decade, andafter beating Ju Wenjun and Alexei Shirov in consecutive rounds, he joined the leading group in the Prague Challengers” (Colin McGourty in chess24.com)

            My concern is about the welfare of the young man, who is going from tournament to tournament. Is too much competition good for his development as a teenager?

                    In yesterday's puzzle by Jochanan Afek the only correct solution is 1. Ka8! and the next White's move leads to inevitable mate

                    ____________

                    From the official site:

                    The 7th round for Masters and penultimate round for Challengers tournament started today in Don Giovanni Hotel in Prague. Co-owner of Czech Inn Hotels, Mr. Jaroslav Svoboda, was the special guest in the playing hall. Mr. Svoboda made the symbolic first move in the all-Czech derby of the Masters group Navara vs Láznička and officially started the round.

                    "Game of the Day" prize went to Grandmaster Alexei Shirov, for his beautiful victory against Ju Wenjun in the 7th round of Challengers event.

                    All eyes were on the game Nikita Vitiugov vs Jan-Krzysztof Duda, as the top encounter of the 7th round in the Masters event. Najdorf was played, and Vitiugov found a nice idea with Ra4-Rb4 to prevent Black from pushing b5. Eventually, Black did push it, but at cost of ending up with pawn down. Duda took the b2 pawn, which turned out to be a blunder. Vitiugov punished it right away with nice tactical combination where he won a piece. The Russian even won in style by checkmating his opponent, to take the sole lead in the event.

                    Another interesting game was all-Czech derby between David Navara and Viktor Laznička, which started with Scotch and became very sharp. Láznička made few inaccuracies and his position was slowly getting worse. Navara eventually won the game, to score his first victory in the event

                      Actually 1.Ra2 is refuted by the kamikaze Qg3+!! but 1.Rf2 should do the trick.

                          DAVID ANTON WINS PICF CHALLENGERS

                          David Anton Guijarro wins Challengers tournament of the 1st Prague International Chess Festival 2019! He drew in the final round with R.Praggnanandhaa and triumphed with 6 points out of 9.

                          The round started with the symbolic first move in the deciding game between Anton and Praggnanandhaa, made by Mr. Macauley Peterson, Editor in Chief of ChessBase, who has been the guest of the Festival for the last few days.

                          The match of the day, between David Anton and R.Praggnanandhaa attracted lot of attention of the spectators and chess fans in the playing hall. It started with English opening, interestingly with the variation named by one of the participants of the event: the Kramnik-Shirov variation! After 12...c6 White got very comfortable position, and soon he started pressing more and more, and with slight help of Pragg, he got clear advantage. The game went into an endgame with pawn up for Anton, and after the first time control, it seemed the Champion will be decided any minute. However, with few imprecise moves, it didn't seem winning path is so clear anymore.

                          In the meantime, Jan Krejči failed to convert much better position against Women's World Champion Ju Wenjun, and the draw was agreed in the opposite color Bishop endgame. This meant that Anton only needed a draw to win the title. He played some more move, trying to convert, but eventually draw was agreed.

                              VITIUGOV WINS PICF MASTERS

                              Nikita Vitiugov wins the 1st edition of the Prague International Chess Festival Masters! The Russian Grandmaster scored 5,5 points out of 9 rounds and convincingly triumphed.

                              The first game to finish was Polish derby between Jan-Krzysztof Duda and Radoslaw Wojtaszek, by move repetition. Nikita Vitiugov needed a draw to avoid tie-breaks and secure the title. At that point, his position was equal, and shortly after draw was agreed.

                              "Every player is happy after winning a tournament. Maybe it was not a great performance, but I am still happy to have won", said the 1st Masters Champion. "I was moved when I was invited here, and it was an honor to participate in such an event", said Vitiugov.

                              Boris Gelfand surprised with quick victory against Harikrishna Pentala in the final round, eventually scoring 5/9. "My opponent had a poor day, it happens to everyone. His position collapsed and I had an easy game", said Gelfand. "Maybe things could have been different for me. Yesterday I had good winning chances, and I should have focused more in the crucial moments. Of course, it is a good result for me, especially because recently I did not play so well. I am happy to be here and I am satisfied with my tournament", said the famous Grandmaster after the game.

                              Vidit Gujrathi defeated David Navara to join Wojtaszek, Duda and Gelfand on shared 2nd place. Eventually he finished 2nd, thanks to better Sonneborn-Berger.
