    Tbilisi 2015

    Round Five
    February 20, 2015

    Commentators are WGM Keti Tsatsalashvili and GM Tornike Sanikidze. Their table appears to be near a door and throughout the commentary the sound of the door being open and closed is quite distracting.

    Also, there is a very small viewing rectangle in the bottom left of the screen for seeing the commentators; the major part is occupied by the board and analyses. At least you can’t see the door.

    First game to finish is Jakovenko-Grischuk:

    kamalakanta: Favorite short draw story....Bronstein is playing Smyslov in the 50's...in a USSR Championship....they draw in 13 moves...the arbiter protests, saying "there is much play in the position! You must play on! The State pays you!"

    Bronstein replies..."You want me to attack Smyslov...for 3 rubles a day?"

    Comments from the Official Site:

    Jobava - Mamedyarov 1-0

    After the poor start 0,5/4 the Georgian star returned into competition with a victory against Shakhriyar Mamedyarov.

    Jobava used the same unorthodox opening he already tried against world champion Magnus Carlsen this winter.

    At one point white sacrificed a pawn but then missed the best continuation and black took the tempo to solidify the structure.

    The only way to retain some chances was to also sacrifice a bishop, which is exactly what Jobava did.

    After several forced moves black made a terrible mistake, completely blundering white's 19.Rxd5. Mamedyarov said he immediately wanted to resign but then he noticed that 19...Qb4 allows him to stay in the game a little longer. 18...Qc7 19.Qb2 where Jobava claims to have good compensation.

    White committed another inaccuracy on move 22, but black quickly returned the favour and ended up checkmated.

    Zurab Azmaiparashvili pointed that 22.Rd8+ Rxd8 23.Rxd8+ Kf7 24.c3 would win on the spot.

    Vachier Lagrave-Radjabov ½
    Andreikin-Dominquez 0-1
    Kasimdzhanov - Svidler 1-0

    Svidler defended with his favourite Gruenfeld Indian and Kasimdzhanov repeated the line that he used against Giri in Round Three

    Black deviated from Giri's play by preventing e4 advance, and was then "treated to his own medicine", as Svidler put it, because he introduced white's line in the Candidates' game against Gelfand.

    By now the main line is 8...c5 9.dxc5 N6d7, but Svidler borrowed Gelfand's forgotten idea of Bg4-Bxf3, only with a small twist - 10...N8d7 which saves valuable tempo and is much superior to the known 10...c6.

    White was taken by surprise, but nevertheless he continued with normal development and castled long. He refrained from pushing the h-pawn, and Svidler has shown why he was right - 15.h4 Rad8 16.e5 f6 17.h5 fxe5 18.hxg6 h6 and black rook is great on f8.

    The players have suggested several alternative variations:

    15...Rac8!? (Svidler)
    16...e5!? 17. f5 gxf5 18.Qxf5 Ne6 "with a monster knight on d4" (Kasimdzhanov)
    16...Rxd2 17.Rxd2 Bxc3 18.bxc3 Rc8 19. Ka1 Nca4 etc (Kasimdzhanov)

    Svidler underestimated 18.Nb5! and both players agreed that the position after 20.Qa3 is extremely complicated.

    The losing move was 23...Rf7, both agreed, and tried to find a possible improvement:

    23...Rxb4 doesn't work 24.Qxb4 Nf6 25.Nxd5 Nxd5 26.Qc4
    23...Qf7 24.Bxc5 Rf1 25.Rd1; 23...Qh4 24.Nxd5 and g3 is a huge threat; 23...Qd6 24.Bxd7 Qxd7 25.Bxc5
    23...Rc4 (engine) 24.Nxd5 Qf7 25.Ne3 Rxb4 26.Qxb4 Nd3 27.Qd6 Nxe1 28.Be6 etc

    Tomashevsky - Giri 1/2

    The tournament leader attempted to repeat the line in the King's Indian Defence that he used against Grischuk, but met with a well-prepared Giri.

    White was prepared for 11...h6 12.Bd2 Na6 13.Bg2!?, but black changed the moves order and white started losing ground.

    The hasty 13...f4 14.gxf4 exf4 15.Bd4 would have turned bad for black, but he played the strong 13...Nh7 to which white couldn't remember how to continue.

    Giri suggested the calm 14.a3, but instead white committed himself with 14.h4. Tomashevsky admitted that his "position started falling apart" and that "black has won the theoretical duel".

    After 24...b5 white realised that he was outplayed and should look how to save the game. He did put up a stubborn defence and eventually earned a draw.

      Re: Tbilisi FIDE Grand Prix

      The chances of Tomashevsky being 1 of the 8 Candidates continue to increase. His draw against Dominguez maintains his full point lead and the top seed, Grischuk, is no longer one of his pursuers after going down in flames to Radjabov. And the #2 seed, Giri, could only manage a draw against Jobava, who perhaps has righted his sinking ship (:

      Had Giri won that game, he would have been a live #2. Instead he's only #5, which goes to show what a great race it's going to be for those 2 Candidates spots based on rating. It's the average 2015 rating that's all important so those big numbers Caruana had the last 3 months of 2014 are totally irrelevant. Since both Caruana and Grischuk are but a single loss away from losing their 2800 status, it's now entirely possible (albeit still not likely) that Carlsen may soon have exclusive 2800 status.

        Re: Tbilisi FIDE Grand Prix

        The chances of Aronian securing 1 of those 8 Candidates spots become more and more remote. He's not playing in the Grand Prix so has zero chance of qualifying via that avenue. And after giving up a draw to the world's 2nd strongest IM, 16-year-old Alexander Donchenko, in the Bundesliga today, he's again out of the Top 10 in rating. His chances of qualifying via rating aren't a whole lot higher than zero. That only leaves the 2 spots from the World Cup and that's always a crap shoot at best. I'm assuming, of course, the Wild Card entry will go to either Nakamura or So given the 'likely' American venue (and given they both haven't otherwise qualified).

            It's only rumoured at this point so I'm definitely jumping the gun here. If the World Championship is to indeed be held in the U.S. (as indicated at the following Wikipedia link), then it is rather logical (:

              Round Six
              February 21

              Well, well – a poisoned pawn Sicilian! Radjabov seemed to know more of its intricacies than Grischuk so:

              Tbilisi 2015
              Round 6, Feb. 21
              Radjabov, Teimour – Grischuk, Alexander
              B97 Sicilian, Najdorf, Poisoned Pawn Variation

              1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Qb6 8.Qd2 Qxb2 9.Rb1 Qa3 10.e5 h6 11.Bh4 dxe5 12.fxe5 g5 13.Bg3 Nh5 14.Ne4 Nd7 15.Rb3 Qxa2 16.Be2 Nc5 17.Nc3 Nxb3 18.Nxb3 Bb4 19.Bxh5 Qb2 20.O-O Qxc3 21.Bxf7+ Ke7 22.Qf2 Kd7 23.Qb6 Rf8 24.Be1 1-0

              Radjabov played the interesting 13.Bg3, because according to him "the main line 13.exf6 is deeply researched, all the way down to a draw".

              The game pursued its normal course until Grischuk committed a grave mistake with 16...Nc5. He should have played different move order, starting with disrupting check 16...Qa1+ 17.Bd1 Nc5 18.Nxc5 Nxg3 19.hxg3 Bxc5 20.c3.

              Another mistake followed with 18...Bb4, when 18...Nxg3 19.Nxa2 Nxh1 would have given some chances in unbalanced position. Grischuk missed that after 19...Bxc3 20.Qxc3 Qb1+ white has simple 21.Bd1.

              The game was finished in a matter of couple of moves. (From the Official Site)

              Vachier Lagrave-Kasimdzhanov ½

              Dominguez Perez-Tomashevsky ½

              Peter Svidler wins in the Berlin:

              Tbilisi 2015
              Round 6, Feb. 21
              Svidler, Peter – Andreikin, Dmitry
              C65 Ruy Lopez, Berlin Defence

              1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.d3 Bc5 5.O-O d6 6.Nbd2 O-O 7.c3 Bb6 8.Bxc6 bxc6 9.Re1 Re8 10.h3 Nd7 11.d4 exd4 12.cxd4 d5 13.b3 c5 14.exd5 Rxe1+ 15.Qxe1 Bb7 16.Bb2 Bxd5 17.Qe3 cxd4 18.Bxd4 Nf8 19.Ne4 Qe7 20.Re1 Ne6 21.Nc3 Bc6 22.Bxb6 axb6 23.Nd4 Bd7 24.Nd5 Qc5 25.Nxe6 Bxe6 26.Qxc5 bxc5 27.Nc3 Rb8 28.Re5 c4 29.bxc4 Bxc4 30.Rc5 Be6 31.Rxc7 Kf8 32.a4 Rb3 33.Ne4 Bd5 34.Nc5 Rb1+ 35.Kh2 Rb2 36.Kg3 g5 37.Rd7 Bc6 38.Rd6 Be8 39.a5 Rb5 40.Rd5 Ke7 41.Rxg5 Rxa5 42.Re5+ Kd6 43.Rxe8 Rxc5 44.f4 1-0

              In this Anti-Berlin Ruy Lopez white played a relatively rare 8.Bxc6, which Svidler doubts anybody will repeat soon. 8.h3 was leading to normal theory according to him.

              Svidler also pointed that 11.d4 was a mistake and after that white has to be careful in order to equalise. He added that 11.Nf1 was better. On move 19 he was lucky that Ne4 is working.

              Andreikin later missed 21...Bxf3 22.Qxf3 Rd8 to be equal. After the game continuation white suddenly got some play. Andreikin admitted that he missed 24...Qd6 would run into 25.Nf5.

              The resulting endgame was quite pleasant for white, he won a pawn and continued pressing for a win, while black was in huge time trouble.

              Perhaps black could have tried 27...Ra3 28.Rc1 Kf8 "with a long game ahead". As it happened, white advanced his passed pawn and duly converted the advantage. (From the Official Site)

              Mamedyarov’s first draw in the tournament:

              And the last game to finish. Giri said that he would normally fight out the long endgame but he didn’t here because it was drawn and there was no point and everyone applauded and thanked him otherwise they would still be playing. Jobava said this was the first game in which he did not make a sacrifice – he wanted to see what normal play was like.

              In the opening which was a hybrid of Slav and Gruenfeld Indian, black conceded a pair of bishops in order to solidify the center.

              White however responded with the strong 12.Qa4. The queens went off, but white emerged slightly better from the opening, both players agreed.

              White prepared the central push e3-e4, but he underestimated the strength of the black bishop on e3. 27...f6 was a strong move which prevented white from blocking the center.

              Jobava said that his plan was to play 31...f5 in order to prevent Ne4, but then he just changed his mind and allowed the jump.

              This caused some coordination problems for black because white held two bishops and the game was opening up.

              Some of the proposed lines were:

              33...Nxd5 34.exd5 f5 (Jobava)
              34...Nc2 35.Re2 Nxe1 or Ng3+ (Giri)
              44.Ba6 Rb6 (44...Ra7 is losing) 45.Bc4 Nc6 46.Ke3 when black is facing a very difficult defence (Giri)

              Black did hold well and was finally awarded the draw after six hours of play. (From the Official Site)

                The only prohibitive betting favourite tomorrow is Grischuk and that number (31/20) surprises me given the plus 2, minus 1, equal 6 score (in Grischuk's favour) between these two.

                  That's probably the best try against the Sicilian Najdorf with 6. Bg5.

                    Jakovenko's win against Giri moves him to clear 2nd and within a 1/2 point of Tomashevsky (who drew with Svidler), but Tomashevsky is arguably now the most likely Russian to qualify for the Candidates since Grischuk's loss to Mamedyarov leaves him an improbable qualifier via the Grand Prix and now only #5 in the live rankings. With the sole exception of Nakamura, it has not been a good month for the world's Top 15 ):

                        Round Seven
                        February 22, 2015

                        The round started with three draws, viz:

                        Andreikin, Dmitry – Vachier Lagrave, Maxime ½

                        Kasimdzhanov, Rustam – Radjabov, Teimour ½

                        Tomashevsky, Evgeny – Svidler, Peter ½

                        Tbilisi 2015
                        Round 7, Feb. 22
                        Jakovenko, Dmitry – Giri, Anish
                        A88 Dutch, Leningrad, Main Variation (with c6)

                        1.Nf3 f5 2.d4 Nf6 3.c4 g6 4.g3 d6 5.Bg2 Bg7 6.O-O O-O 7.Nc3 c6 8.Rb1 Ne4 9.Qc2 Nxc3 10.bxc3 e5 11.dxe5 dxe5 12.Ba3 Rf7 13.Rfd1 Nd7 14.e4 Bf8 15.Bxf8 Qxf8 16.Qd2 Rf6 17.exf5 gxf5 18.Qg5+ Rg6 19.Qe3 e4 20.Nh4 Rg7 21.f3 exf3 22.Qxf3 Nc5 23.Rd4 Ne6 24.Rd2 Ng5 25.Qf4 Be6 26.Re1 Qf6 27.Qd4 Rf8 28.Rf2 Rgf7 29.Qxf6 Rxf6 30.Rf4 h6 31.a3 Kg7 32.Re5 Kg8 33.Bf1 a6 34.Kg2 Rd8 35.g4 Rd2+ 36.Re2 Rd3 37.gxf5 Bf7 38.Re8+ Bxe8 39.Bxd3 c5 40.Rg4 Rb6 41.Ng6 Rb2+ 42.Kg3 Bxg6 43.fxg6 Rb3 44.Bf5 Rxc3+ 45.Kg2 Rxa3 46.h4 Ra2+ 47.Kg3 Ra3+ 48.Kg2 Ra2+ 49.Kg3 Ra3+ 50.Kf4 Nh3+ 51.Ke5 Kg7 52.Rg2 Rf3 53.Rd2 Nf4 54.Rd7+ Kg8 55.Rxb7 Nh5 56.Be6+ Kf8 57.Ke4 1-0

                        The game was a Dutch Defence, where after the regular opening moves Giri was "feeling good about the position around 16.Qd2".

                        But a couple of moves later he was worried about 23.Rf1 and 24.Bh3 where white wins a pawn. Jakovenko also had his doubts, as he didn't like the looks of 28...Qxd4 29.cxd4 f4 30.d5 cxd5 31.cxd5 Nh3+!.

                        The players had different emotions about the game around move 32 - Giri was feeling uncomfortable, while Jakovenko was not pushing, he was just making normal-looking moves until he would come up with a plan.

                        The ending after the time control was extremely complicated. 40.Rg4 looks clumsy but it is a very good move, which prepares the advance of h-pawn. However, 44.h4 was still premature as 44...Rxc3 45.hxg5 h5 shockingly wins for black.

                        Giri said that 46...Ra2+ was a mistake that allowed white king into the game. He should have played 46...Nf3 47.Re4 Kf8, which might hold. He admitted missing the powerful idea of 52.Rg2-d2, but even 51...Nf2 52.Rd2 Nd3+ 53.Ke4! appears to be winning for white. He reminded of the famous ending Capablanca-Tartakower where the world champion gives away his pawns in order to penetrate with the king.

                        In summary, Giri said that he made enough mistakes that he deserved to lose. (From the Official Site)

                        Round 7, Feb. 22
                        Grischuk, Alexander – Mamedyarov, Shakhriyar
                        D52 QGD

                        White spoils his home preparation with 17. Ra5. IM Tihomir Yanev annotating at chessbomb ends with:

                        “And it's finally over. What was going to be misery for Mamedyarov, who was caught in a home preparation (perhaps), turned to be a dramatic game after a shocking blunder on move #17. Grischuk tried his best to save the game but black's passed pawns were too strong.”
                        An extremely exciting game that started as Queen's Gambit Cambridge Springs where white offered two pawns as sacrifice.

                        Black snatched one, but passed on the second as white would have developed tremendous attack, for example 11...Qxb2 12.Rc2 Qa3 13.0-0 Be7 14.Bg3 f5 15.c5.

                        Black tried to challenge opponent's central supremacy with c5 and e5, but white would have been better after 17.dxe5 Nxe5 18.Qd5 f6 19.Qxe4 0-0 20.Qc2.

                        Instead, Grischuk made a terrible mistake 17.Ra5, missing black's "long" move Qb6-h6. The pin on white queen allowed black to emerge two pawns up, but in much better version compared to the 11th move. Now his defended passed pawn on d3 was very dangerous.

                        The technical phase took some extra time as white had certain activity due to opposite coloured bishops. But after the second time control Mamedyarov finally brought the victory home. This was his third win with black pieces. (From the Official Site)

                        Round 7, Feb. 22
                        Jobava, Baadur – Dominguez Perez, Leinier

                        The local hero Baadur Jobava played the Reversed Philidor Defence, for the 7th time in his career. In this seemingly passive setup Jobava has won five games and conceded only two draws against world-class opposition.

                        Perhaps white did misplay the opening a bit, as the wandering knight allowed black to reposition his own knight to a better place, also clearing the way for the c-pawn.

                        Dominguez pointed that 13...c6 was better before trading on e4 because he has 14.Qc2 Qb6. With the game continuation he missed that after 15.Qc2 Qb6 white has simple 16.Nc4 (pawn no longer on d5).

                        He admitted that the misstep made him very upset and he couldn't bring his head back into the game. Jobava also noted that black started making erratic moves and that white position kept getting better and better.

                        Dominguez was also burning the clock and finally he was required to make six moves in 40 seconds. He was finding the best solutions, as praised by Jobava, until he stumbled and made decisive mistake on move 39. Dominguez said that he didn't even consider 39...Nd6, which turned to be superior. There was simply no time.

                        After the time control white was left with the pleasant duty of converting the advantage. (From the Official Site)

                          Despite the fact that Tomashevsky may well be leading the field heading into the 4th and final Grand Prix in Khanty-Mansiysk in just under 3 months time, 'Chess By The Numbers' still only has him as the 3rd favourite to secure one of the two Candidates spots via this avenue. I think the 30% probability cited therein is grossly understated however since both Caruana and Nakamura are very much in the hunt for the 2 Rating qualifiers which could well take one, or possibly even both, out of the Candidates equation. The 30% number equates with finishing 1st or 2nd when finishing 3rd, or possibly even 4th, may be good enough.

                            There's no betting line on the Radjabov - Mamedyarov game tomorrow. I'm assuming that's because these 2 Azeris nearly always draw (22/24 or 91.67%). And once again, the prohibitive betting favourite, Svidler at 93/100, is a horrible bet against Jobava. Jobava has won his last 2 games, is dead even against Svidler in 4 prior encounters (2 draws and a win each), and clearly shouldn't be a 7/1 dog tomorrow in his home country.

                              Marathon certainly was wise not to allow betting on the Radjabov - Mamedyarov game. The first game to finish ended in a highly predictable draw. And I certainly got it right (at 7 to 1!) in the Svidler - Jobava match. With his win today, Jobava has won 3 games in a row and has now happily returned to the land of the elite, the 2700 plus club (:

                                As the MVL-Tomashevsky game drags on, there is much ChessBomb discussion of the 50-move rule since Tomashevsky continues to avoid capturing MVL's last pawn, presumably to keep the count from commencing in a BBN vs R (+P) endgame. In reviewing Wikipedia's commentary on the 50-move rule, I note that there was a game played in 1966 between Filipowicz and Smederevac that invoked the 50-move rule with all 32 pieces still on the board!
