Mamedyarov Wins World Rapid Championship

Shakhriyard Mamedyarov trailed Ian Nepomniachtchi by 2.5 points entering the last day; that is, with five rounds to go, and besides that he lost in their individual game, which meant that if the two of them tied for first Nepomniachtchi would win the title of World Rapid Champion on tiebreak. With Nepomniachtchi "on fire" with 9/10 after the first two days, the idea that Mamedyarov could win seemed almost absurd...but win he did.

Whatever Nepomniachtchi had going those first days disappeared on Saturday. He drew his first two games with difficulty, while Mamedyarov won his first two to close to within a point and a half. Mamedyarov won his third game too, and in the meantime Nepomniachtchi lost with the white pieces to Alexander Grischuk. That put Mamedyarov just half a point back and Grischuk a point behind. In the penultimate round Nepomniachtchi drew - again with difficulty - while Mamedyarov won with Black against his countryman Gadir Guseinov and Grischuk beat Francisco Vallejo Pons. Mamedyarov's win was odd, as Guseinov self-destructed in a draw rook ending, succumbing perhaps to the deadly combination of too much ambition and too little time on the clock.

Going into the last round then, Nepomniachtchi and Mamedyarov were tied for first, with Nepo having in effect draw (or tie) odds, with Grischuk half a point back. If they finished in a three-way tie it would have been Grischuk who would triumph on tiebreaks, so amazingly there was still everything to play for. Nepomniachtchi had White against Alexander Riazantsev, but didn't gain an advantage and Black obtained a fairly easy draw. Grischuk couldn't win with Black against Nikita Vitiugov either, but Mamedyarov broke through once again, finishing the day 5/5 by defeating Ernesto Inarkiev.

That was a great result by Mamedyarov, and a startling collapse by Nepomniachtchi, though again in keeping with the recent trend of tournament leaders falling to pieces on the last day: Carlsen, Kramnik, Moiseenko, Kamsky, etc.

London Grand Prix: Gelfand, Mamedyarov and Topalov Tie For First

The first leg of the current FIDE Grand Prix has come to an end, with three players sharing first (no tiebreaks) in the inaugural leg in London. Shakhriyar Mamedyarov came into the round in clear first, but whether due to a lack of ambition or simply good prep from Peter Leko he got nothing with the white pieces and finished quickly (in terms of time) with a 41-move draw.

That gave Boris Gelfand, Veselin Topalov and Alexander Grischuk the chance to catch him in a tie for first, if they could win in the last round, and two of them did. Grischuk had White against Hikaru Nakamura, but despite that and the latter's generally poor form in the tournament he held a draw without much trouble. Nakamura repeated a relatively minor line of the Dragon he used as a surprise weapon against Anish Giri in Wijk aan Zee earlier this year. Grischuk was probably prepared and varied first, but may have been surprised anew by Nakamura's 18...Rab8 (18...b4 is usual). Grischuk didn't get much, and after 24.Bxg7 (the engine claims that 24.axb4 may offer White a very small edge...maybe) it was equal and the players were satisfied with an unforced (but reasonable) draw by repetition.

Veselin Topalov won a Carlsen-like game. Anish Giri had a very small pull with White in a Queen's Gambit Declined sideline, but it looked for all the world like it was heading for a quick draw. It was an even ending, but Giri started to drift. His 30th and 31st moves weren't so bad, but they sowed the seeds of his later troubles. The bishop remained shut out on a5 for a long time, while 31.h4 allowed Topalov to break up the kingside and eventually create a pair of central passers. For whatever reason, Giri was badly outplayed in the endgame, and Topalov won (or at least tied for first) in a major event for the first time in some years.

Another player who had gone quite some time without winning a round-robin event was Boris Gelfand, but with an impressive win over Rustam Kasimdzhanov, he did it. Generally speaking, it was a convincing victory, but as he admitted after the game he "blundered" 14...Bc6. (Linguistic note: there's a strange trend I've only noticed over the past year or so, but it seems to be everywhere now, and that's using the word "blundered" as a synonym for "overlooked". That isn't what the word means!) Fortunately for him, Kasimdzhanov "blundered" it too, and Gelfand went on to win in style. Kasimdzhanov blundered (correct usage!) into a forced mate at the end, but even without the helpmate White's win was routine.

Final Standings:

1-3. Topalov, Gelfand, Mamedyarov 7
4. Grischuk 6.5
5. Leko 6
6. Wang Hao 5.5
7-8. Ivanchuk, Adams 5
9-10. Kasimdzhanov, Dominguez 4.5
11-12. Giri, Nakamura 4

London Grand Prix, Rounds 6 & 7: Gelfand Still Leads, Mamedyarov Surges, Nakamura Falters

In round 6 of the London Grand Prix the action heated up after two rest days, one official and one not. Three games were decisive, and the other three were interesting as well.

The leader, Boris Gelfand, drew with Vassily Ivanchuk in just 25 moves, but it was extremely interesting and saw the players break new ground. After 4.g3 Ba6 5.b3 b5 in a Queen's Indian, Gelfand played the relatively rare 6.Nbd2, to which Ivanchuk replied with the extremely rare 6...c5. Gelfand's response was a novelty, sacrificing a pawn with 7.d5. Such ideas are common, especially in the Queen's Indian, but with a knight on d2 and the pawn on b5 it was a genuinely different setting. Both sides had plenty of options along the way, so it would be interesting to see other players take up this variation. After a complex middlegame, the players repeated moves, and this was not a matter of laziness or fear: the repetition really was best for both players.

Alexander Grischuk's game with Michael Adams was instructive for those who play closed systems against the Ruy. Adams' 16...c4 inaugurated a typical idea for Black in the Ruy, though in an unusual setting. (The normal setup sees Black play ...d5 to create a center where both players' center pawns are attacking each other.) This more or less sacrificed a pawn to get the bishop pair and control of d5 with a light-squared bishop against an extra but isolated d-pawn. Adams drew without any special difficulty.

The draw between Peter Leko and Anish Giri was interesting as well. Leko gave up a pawn for a nasty initiative as White in a Byrne Attack Najdorf (sometimes mislabeled the English Attack, but that's only when Black meets 6.Be3 with ...e6; when it's ...e5 then American GM and former Candidate Robert Byrne gets the credit). It looked like Giri might be in some trouble, too, but 18...a5! was just the thing to spark his counterplay, and came just in the nick of time. Leko decided to keep things safe after that, and the result was a heavy piece ending where neither side could make any progress without serious risk to his king's safety.

On to the decisive games. Hikaru Nakamura lost his third straight game to Wang Hao. He played a Reti and the position soon locked up. In the trench warfare that ensued, the most important pawn break would be ...f5, so Nakamura might have considered (and probably did consider) 34.g4 (not just restraining Black, but with the idea of pushing on to g5) as well as meeting 34.Nb1 Bxd5 with 35.cxd5, even though it's a pawn sac. On move 37, Nakamura's 37.Bc1 either missed or underestimated Wang Hao's "sweeper sealer" 37...e4! 38.dxe4 f4, followed by the second sac 39.g5 f3! Black was clearly better by this point, but not yet winning in case of 40.Bh3. Short of time, Nakamura grabbed the pawn with 40.Bxf3, and after 40...Be5 was lost. Black finished off with a series of power shots and gained the full point after his 47th move.

Rustam Kasimdzhanov played a rare line against Shakhriyar Mamedyarov's Meran and seemed to obtain an advantage, but he couldn't figure out what to do with it. One thing it seems he definitely should not have done was allow Mamedyarov's pawn to f3. There were plenty of inaccuracies and outright errors after that (notably, 29...fxg2 won pretty much on the spot - 30.Bxg2 Ng4 being the most obvious and straightforward point), but White's weak kingside eventually cost him the point.

Finally, Veselin Topalov won a nice game with White against Leinier Dominguez. A slow strangulation-style game finished in a more characteristically Topalovian way, as he gave up a piece for what was eventually three pawns. As those three pawns were far advanced, connected passers and Dominguez's bishop had little to do, White won in comfort.

That was round 6; on to round 7. Dominguez-Leko, Wang Hao-Topalov, Giri-Grischuk and Ivanchuk-Kazimdzhanov were all drawn; the last one, incredibly, in just 11 moves. If there's any mystery to this game it's around Kasimdzhanov's decision not to go for more with 7...Nb3. Then Black's queen has the c5 square, thus ruling out the "perpetual" in the game. The engines don't think White's compensation is sufficient, but judging by the speed with which the players finished I'm sure they know perfectly well what the engines have to say, and know that in the end White is doing alright.

As for the decisive games, there were two. In one of them, Mamedyarov-Nakamura, both players continued their trend from yesterday: Mamedyarov won again to reach clear second, while Nakamura lost again and fell into a tie for last. Mamedyarov just outplayed Nakamura from the jump in a Fianchetto King's Indian, and although Mamedyarov often failed to prosecute his advantage as cleanly as he might have, he never let Nakamura catch back up, either. After 33...Qxc5(?), White's advantage was decisive, and there were no further hiccups. 37.Rxf4 was a nice shot, and Mamedyarov handled the final tactics perfectly.

This would have put him into a tie for first, were it not for Gelfand's managing to win once again. Adams decided to put Gelfand's 2...Nc6 Sicilian to the test with the Rossolimo, but instead of an immediate swap on c6 (a la several of the Anand-Gelfand world championship games) he allowed Black to play ...Nge7 first and to recapture with the knight. Adams' position was certainly more pleasant to the eye and seemingly easier to play, but Gelfand's position relied on the power of the bishop pair. If he could unravel on the kingside, then the bishops (plus potential pressure down the c-file) could give him an advantage. Adams thus hastened to open the board before Black could finish his development, and with 24.c5 gave up a pawn. He never quite had enough, but he maintained some compensation until 34.Ng5?, a tactical error that allowed Gelfand to liquidate to a won rook ending.

Winning the game, Gelfand moved to plus three and maintained his lead over the field. He has 5/7, Mamedyarov has 4.5, while Grischuk, Topalov and Leko all have 4. Here are the round 8 pairings, with player scores in parentheses:

• Leko (4) - Grischuk (4)
• Gelfand (5) - Giri (3)
• Kasimdzhanov (2.5) - Adams (3)
• Nakamura (2.5) - Ivanchuk (3)
• Topalov (4) - Mamedyarov (4.5)
• Dominguez (3) - Wang Hao (3.5)
