Not for the first time, either - he won the title back in 2006 as well. So Alexander Grischuk is a two-time world blitz champion, winning this year's event by a hair over Magnus Carlsen. Grischuk played well both days, and thanks to a winning streak in rounds 22-25 was able to coast a bit near the end. In round 26 against Carlsen he was a bit careless - he could have held a draw pretty easily but pushed for more. After all, with a three point lead with just five rounds to go, what could go wrong?
Well, in addition to losing that game (now just a two point lead), Grischuk lost to Peter Svidler in round 28, and it was only a one point lead with two rounds to go. Grischuk beat Viktor Bologan with Black in round 29 and clinched first by repeating a known theoretical draw on the white side of a Petroff against Nikolay Chadaev. A good thing, too, as Carlsen was just half a point behind at the finish.
In fact, Carlsen, whose score after 22 rounds was a miserable (by his standards) 11.5-10.5, won the last eight games. It was a pretty remarkable run, and once it got started you could feel Carlsen's self-confidence grow to epic proportions. The hubristic high point came against Teimour Rajdabov in round 26, when Carlsen opened with 1.a4. (I'm guessing these two don't like each other - especially not now!) Had this monster awakened earlier in the event, he might have won with a colossal margin; as it was, it was still a good performance.
Sergey Karjakin took third, but was in the hunt for first or certainly second before he repeated his late-round collapse from day one, first losing to Shakhriyard Mamedyarov and then to Carlsen. (Badly in both cases.) Still, it was a good week for him: winning the rapid championship and coming in third here.
Dmitry Andreikin was in the hunt for a long time too, but some tough losses in the late going pushed him out of contention and into a tie for fifth with Radjabov, half a point behind Alexander Morozevich. Vassily Ivanchuk had also been in contention after the first day, but he really plummeted, only managing to finish with an even score overall.
Turning to games of interest, other than those mentioned above:
Mamedyarov-Jumabayev was nice - through move 28 the game gives the impression of being one very long opening trap.
Karjakin-Bologan was a blown opportunity for Karjakin, failing to win an ending with an extra exchange and a pawn. It's only blitz, but until his next tournament success he may rue some of the half and whole points he gave away here.
Chadaev-Karjakin: Kramnik's Scotch Four Knights with 10.h3 strikes again! I haven't a clue why people play as they do against it (to take one obvious approach, 11...Re8 12.Bf4 Bd6 gives White a big pile of nothing), but until they do it will keep making the occasional cameo. Chadaev played boldly and caught another big scalp, and in general one has to be impressed by his fearlessness in this event.
Bologan-Gelfand: An amazing endgame "fail" by Gelfand.
Ivanchuk-Jumabayev: 59...g5! is a nice king and pawn ending trick worth noting and remembering.
Carlsen-Mamedyarov: A nice win by Mamedyarov, who won with Black in the Philidor against both Carlsen and Karjakin.
Jumabayev-Svidler featured a very nice (for us) and nasty (for Svidler) defensive trick. It looked like Svidler had at last worked out the mating combination, but there was this one teensy detail he missed.
Topalov-Carlsen was one of the few bright spots for Carlsen early in the day, but one worth savoring. It's usually White who gets to enjoy the boa constrictor-style strangulation games in the Ruy (there's a reason it's called the "Spanish torture"), but this time it was White who was suffocated.
Morozevich-Gelfand featured 10.e5 in the Anti-Moscow Gambit in the Semi-Slav, a move with a reputation for relative harmlessness. I don't know if Morozevich prepared something new and big or if Gelfand was just playing poorly, but the finale was 1-0, 25 moves.
Mamedyarov-Kotsur was an absolutely spectacular game, in which Mamedyarov sacrificed a pawn (declined), then another pawn (accepted), a piece (accepted), another piece (accepted), an exchange (declined) and then a rook (accepted) - and all while leaving the first rook from the declined exchanged sacrifice hanging through the end of the game. It all seems to be sound, and the only minor criticism is that Mamedyarov missed a mate in three starting with 24.Qxb6+.
Andreikin-Gelfand was the nadir of Andreikin's collapse. He had lost to Grischuk and Karjakin in recent rounds, but was still very much in the running for a medal going into round 27. Gelfand fell into an embarrassing, absolutely elementary trap with the blunder 6...Bg4?? - and won anyway. (Incidentally, 7.Ne5 may have been even better than 7.Bxf7+ - one must always consider both ideas in such positions.)

One final note: I haven't been able to find any video archives on the website - it just shows the last bit of whatever they filmed that day - in this case, the closing ceremony. ChessVibes filmed some of the games, though, and you can find them in their YouTube channel or on their site.
