Two players could have caught him with a win, but two of them, Ian Nepomniachtchi and Jan Gustafsson, drew quickly against each other to tie for second. They were joined by two others, Shakhriyar Mamedyarov and Vassily Ivanchuk, who defeated Loek van Wely and Vladimir Kramnik, respectively. Van Wely-Mamedyarov was complex, a race of passed pawns and attacks on opposite sides, and was objectively equal until just before the end. The tournament has been a disaster for the Dutchman, however, and his run of poor form continued. Ivanchuk-Kramnik revisited the Petroff line from round 3's Naiditsch-Kramnik game, and once again Kramnik lost. This time it wasn't due to the opening, however. Ivanchuk had a very slight edge, but Kramnik kept everything under control until after the time control, when an inaccuracy and then a blunder did him in.
The final standings are amusing, and it's a shame that Naiditsch didn't somehow beat Leko - then there would have been a six way tie for first! Here are the Garrison Keillor-approved standings:

Shakhriyar Mamedyarov-Vassily Ivanchuk was also drawn, and quickly, but for those who take the time to closely examine the game, you'll discover genuine value therein. The pawn roller plan used by Mamedyarov can be devastating - witness the famous Botvinnik-Capablanca game from AVRO 1938 - so it's valuable to reflect on the way Ivanchuk coped with that plan.
Finally, the tournament victim (Loek van Wely) was sacrificed on the altar once more, this time to Arkadij Naiditsch, who plastered him in 26 moves. With one round to go, van Wely's TPR isn't even enough for an IM norm, making this almost surely the worst tournament of his adult life.

(HT: ChessBase)]]>Dortmund, Round 5: Gustafsson wins, leads
http://chessmind.powerblogs.com/posts/1215198586.shtml
Dortmund is a very funny tournament. Either Kramnik wins (this has happened eight times), or else it's a complete outsider who takes the title. This year, it looks like another instance...Dennis Monokroussos2008-07-04T19:07+00:00at least one commentator), is in clear first with two rounds to go. This was the result of a very quick, strange win against tournament tail-ender Loek van Wely, whose move 14 novelty gave him an immediately lost position that he resigned four moves later. My best guess is that he was simply unprepared for Gustafsson's move order, threatening the Noteboom Variation, and hadn't reviewed his prep for the Marshall (Slav) Gambit in some time. A disaster for van Wely, but happy days for his opponent.
That game finished pretty quickly, as you might imagine. Next up was a short draw between Leko and Nepomniachtchi. Leko had a small advantage on the white side of a 3.Bb5+ Sicilian, but he was unable to achieve anything with it. When Black played 25...e5 and 26...f5 the game turned double-edged, and a few moves later, just as the game was getting lively, Leko offered a draw, which was accepted.
The next draw was Mamedyarov-Kramnik, a game which caught my eye thanks to Kramnik's surprising - and good - 27...f5. The move looks like positional suicide, but it highlights the need and value of activity in even the quietest positions.
Finally, Ivanchuk won a nice ending against Naiditsch, outplaying him from an almost dead equal position in the opening. A remarkable technical display by the Ukranian, bringing him back to 50% overall.

Round 4 of the Sparkassen Chess-Meeting in Dortmund saw three more draws, but it had its moments....Dennis Monokroussos2008-07-02T17:07+00:00Sparkassen Chess-Meeting in Dortmund saw three more draws, but it had its moments.
The first game to finish was Kramnik-Leko (shock, horror), a 22 move draw by repetition. Despite the quick and uninspiring conclusion, there were places where the game could have livened up, and the game may have a little theoretical significance as well.
Another short draw, finishing just a few seconds later, was Gustafsson-Ivanchuk, but this game was almost everything Kramnik-Leko was not. The opening was very sharp and neither player backed down from the complications. Ivanchuk's opening choice was quite clever: he entered the Vienna Variation of the Queen's Gambit, but then went down a sideline resulting in what looks like a favorable version of the Botvinnik Variation of the Semi-Slav. I think he had a very nice edge, but on move 16, perhaps overly concerned with the possibility of 17.d5, he preferred solidity over aggression, and that allowed Gustafsson to level the game.
After another hour or so, the remaining games finished in a near dead-heat. First came the only non-draw of the round, Nepomniachtchi-van Wely. White sacrificed a pawn for control of d5 and kingside prospects. Black's position was okay, but he wasn't able to find a solution to those problems - even after sacrificing the exchange, the same difficulties remained. White won a further pawn, and despite a hiccup on move 27, Nepomniachtchi's technique was good enough to win with the extra exchange.
Finally, Naiditsch-Mamedyarov ended too, a Taimanov Sicilian where first White and then Black enjoyed a very small edge, but accurate play from both players kept the game balanced.
Pairings for Round 5: (On Friday; Thursday is a rest day)

Ivanchuk - Naiditsch
van Wely - Gustafsson
Leko - Nepomniachtchi]]>Dortmund, Round 3: Three draws and a Kramnik disaster
http://chessmind.powerblogs.com/posts/1214928802.shtml
The games were decided early on today, though not all the games were drawn....Dennis Monokroussos2008-07-01T16:07+00:00
With White, Ivanchuk chose Fischer's 6.Bc4 against Nepomniachtchi's Najdorf, but got nothing. If anything, it was his opponent who had some chances, but apparently neither player felt very comfortable and a draw was agreed on move 19.
Mamedyarov-Gustafsson didn't last much longer, and like the Ivanchuk-Nepomniachtchi game, it ended too soon. With 26.Be2 (instead of repeating with 26.Qe2) Mamedyarov seemed to have a promising position, but he disagreed and called it a day.
The third game to finish was in a sense the first one to end. Naiditsch produced a very clever novelty against Kramnik's Petroff, 19.Qd2. The move offers a full rook, but its real value was psychological. It's often possible to decline a sacrifice and achieve reasonable play, but this was not one of those occasions. After 19...Ng6? 20.Ree1 f6 21.Rad1 Kf7 22.Qe3, White was clearly winning. Kramnik gave up his queen for a rook and knight, hoping to achieve a fortress. It seemed unlikely to succeed, but with a blunder on move 41 he didn't get the chance to find out.
Last but least, the supremely dull van Wely-Leko game yawned to a finish.
Kramnik - Leko
Nepomniachtchi - van Wely
Gustafsson - Ivanchuk
Naiditsch - Mamedyarov]]>Dortmund, Round 2: Lots of wins
http://chessmind.powerblogs.com/posts/1214765279.shtml
Today's games weren't much longer than round one's, but while all four games were drawn yesterday, three of today's games saw the player with White win....Dennis Monokroussos2008-06-29T18:06+00:00
The first game to finish, Gustafsson-Naiditsch, may have featured the event's lowest-rated players, but it was surely the game of the day. Gustafsson introduced a new move in the Vienna Variation of the QGD (16.f4), and while I think Black can neutralize it with 17...Rac8!, it's quite easy to prefer Naiditsch's 16...Rab8 OTB. It's natural and logical, but it loses, and Gustafsson crushed him quickly.
The second completed game was the only draw of the day. Nepomniachtchi had some advantage on the White side of a Closed Ruy, but after missing some opportunities Mamedyarov managed to equalize and draw.
Shortly thereafter, Kramnik finished his crushing win over van Wely in a Colle (Zukertort version)/Slav hybrid. Kramnik made it look easy: Ne5, Qf3-h3, f4, etc...but it's the "etc." that took the skill. One remarkable feature of the game was that despite Kramnik's kingside buildup, he simultaneously managed to lure all of his opponent's pieces to the queenside, with predictable results.
Finally, Leko defeated Ivanchuk in his best style. Step 1: press strategic advantages. Step 2: when the opponent lashes out to relieve the pressure, exploit this tactically. Step 3: calmly cash in the winnings collected in step 2. The game went 57 moves, but it had been decided from move 25.

Four draws today, but they weren't too terrible. The first game to finish (barely) was Mamedyarov-Leko, a 4.f3 Nimzo-Indian. Mamedyarov devised a new idea with 12.Ne2, surrendering the extra, forward, doubled...Dennis Monokroussos2008-06-28T16:06+00:00Mamedyarov-Leko, a 4.f3 Nimzo-Indian. Mamedyarov devised a new idea with 12.Ne2, surrendering the extra, forward, doubled c-pawn in order to give Black a weak c-pawn which he can then win. That's just what happened, but then Leko had the last anti-c-pawn laugh. Given a choice between forcing perpetual, returning the extra pawn by losing his remaining c-pawn or keeping the pawn but giving Leko's rooks free reign he chose door #1, and the game ended on move 24.
Next up, we had a big opening surprise in Gustafsson-Kramnik. After 1.d4 Nf6 2.c4 Kramnik played 2...g6, a move which isn't exactly a normal part of the ex- (and future?) champion's repertoire or seemingly in keeping with his classical tastes. After 3.Nc3 the surprise was partially abated by his third move, 3...d5 (much more "Kramnikian" than a King's Indian), but I still suspect this is some sort of disinformation for Anand (to make him waste time preparing for something he won't play) or is being used to hide novelties in his "real" openings. (Possible objection: Anand never plays 1.d4. Reply: Neither did Leko prior to the 2004 match in Brissago, and it turned out that Kramnik was taken by surprise there.)
Whatever Kramnik's real motives, Gustafsson was clearly taken by surprise, as he wound up spending a fair amount of time repeating a Kramnik(!)-Svidler game that wound up a short, easy draw for Black. That game was drawn after Black's 27th move, and this game differed only in its going two more moves. An easy day for Kramnik, but perhaps a pity to waste such a surprise on the weakest player in the tournament.
Those games ended almost simultaneously, and it took a good while before the third game, Naiditsch-Nepomniachtchi, came to its peaceful end. This was the sharpest game of the day, a 6.Bc4 Najdorf that quickly left theory behind. After the opening a position was reached where Black's king was stuck in the center, but despite White's active pieces Black's bishop pair, strong knight on e5 and counterplay on the g-file was enough to keep the balance. White might have had a chance near the end with the risky-looking 22.g3, but preferred 22.Nd5, forcing a draw by "perpetual" on Black's queen.
Finally, Ivanchuk-van Wely was a Najdorf-turned-Scheveningen with 6.Be2 that saw the Ukranian pressing. Black's isolated d-pawn and White's extra space gave Ivanchuk some chances, but after a series of exchanges White's extra space was a liability. Ivanchuk could prevent perpetual or try to make progress, but not both, and a draw ensued.
After round 1, then, we have an eight-way tie for first, and so predictions for the tournament are still welcomed! Here are the pairings for round 2:
