The World Championship: What's Next?
As I understand it, there are four bits of information to pass along:

1. The Topalov-Radjabov world championship match scheduled for 2007 is off: as far as I'm aware, this match is now off for both parties.

2. Rematch? Have a look here. According to Danailov, "FIDE regulations allow every world champion that has lost the title to challenge the title holder." Danailov proposes a start date of March 3, 2007 in Sofia, Bulgaria. It will be very interesting to see what comes of this.

3. Candidates Matches: These are on for Elista in April of 2007. Pairings for the first round of matches (assuming they don't switch to a tournament format) are Levon Aronian-Magnus Carlsen, Peter Leko-Mikhail Gurevich, Ruslan Ponomariov-Sergey Rublevsky, Boris Gelfand-Rustam Kasimdzhanov, Etienne Bacrot-Gata Kamsky, Alexander Grischuk-Vladimir Malakhov, Judit Polgar-Evgeny Bareev, and Alexei Shirov-Michael Adams. The final four from this event make it on to...

4. The World Championships in Mexico City. The four surviving candidates meet the top 4 from San Luis: Kramnik (replacing Topalov), Viswanathan Anand, Peter Svidler and Alexander Morozevich. At this point, Topalov (or Kramnik, should the match occur when Danailov wants it to and Topalov wins) is out. This is scheduled to occur to begin September 12, 2007.

The End of the Match, On Video
Here's a video of a Russian news report. (Why can't we get such coverage in the U.S.?) Lots of neat footage: the end of the match, Carsten Hensel letting out a yell, a partial tour of the rest area and the bathroom, and some audio clips from Kramnik (in Russian).

The World Championship: A Recap
A strange chapter has closed in chess: at last we've returned to a single champion, but it wasn't easy! Reunification talk had been in the air off and on for nearly a decade, but only after the unfortunate retirement of Garry Kasparov did it actually take place.

But not without plenty of acrimony and controversy - and
The match can be divided up into four segments: games 1-4, games 5-9, games 10-12 and the tiebreaks.

Kramnik, Now Undisputed World Champion, Wins!
Yes!!!

Kramnik rose to the challenge and overcame his defeat in the previous game, winning game 16 and the match. He played a beautiful technical game, but there were still technical difficulties to overcome when Topalov blundered, thinking he had achieved an instant draw.

A fantastic conclusion to a dramatic tiebreaker. What a match!

The final game, with my comments, is here.

A wrap-up post or two will follow later; for now, I close with the final score: Kramnik wins 8.5-7.5 (8.5-6.5 counting only games that were played), 2.5-1.5 on tiebreaks.

Kramnik-Topalov: Topalov Strikes Back!
If Topalov's anything, he is resilient! Needing to win with the White pieces, he pulled it off. Kramnik was in decent shape after the opening, but the position that arose featured a precariously unequal equality. Objectively, the position was probably equal; practically, it was in Topalov's favor, for two reasons. First, his position was easier to play; second, the cost of a mistake by him was fairly minimal, while a Kramnik error would be catastrophic. And so it was: Kramnik's 34...Ke7 may have been well-motivated, but it turned his king into roadkill.

All tied up, with one rapid game to go! If it's still tied after that, they move on to the blitz games.

Game and notes here.

Kramnik-Topalov, Kramnik Wins the Second Playoff Game
Kramnik won a very nice game, outplaying Topalov in a Semi-Slav. Remember, it's not over yet: there are still (up to) two games to play.

Game, with comments, here.

Kramnik-Topalov, First Playoff Game Drawn
Kramnik came out of the box with an edge with the Black pieces, but some strange-looking rook moves on the c-file left White with the advantage. Fortunately, just when he looked like he was getting into some trouble, he found the very nice tactical resource 36...Nc4!! 37.Bxc4 b6, with the idea that the otherwise very strong 38.Bb3 is met by 38...axb3! 39.Rxa7 Rxa7 with a big plus.

Game and notes here.

Kramnik-Topalov: The Tiebreak Schedule
From the official rules (copied from the ChessBase site):

3.7 Tie-breaks

3.7.1 If the scores are level after the regular twelve (12) games, after a new drawing of colours, four (4) tie-break games shall be played. The games shall be played using the electronic clock starting with 25 minutes on the clock for each player with an addition of 10 seconds after each move.

3.7.2 If the scores are level after the games in paragraph 3. 7.1, then, after a new drawing of colours, two (2) five-minute games shall be played with the addition of 10 seconds after each move.

3.7.3 If the score is still level, the players shall play a single decisive sudden death game. The player, who wins the drawing of lots, may choose the colour. White shall receive 6 minutes, black shall receive 5 minutes, without any addition. In case of a draw the player with the black pieces is declared as winner.
Kramnik 6, Topalov 6: Tiebreaks Tomorrow
Game 12 of the match was perhaps its best-played game, and left the match tied at Kramnik 6, Topalov 5. Tiebreaks tomorrow, unless hell freezes over, pigs fly and the Bulgarians allow game five to be played.

Meanwhile, the tense, exciting and accurately played game 12 can be replayed here, with my annotations.

When Will Game 12 Take Place?
When I posted my write-up for game 11, I initially claimed that game 12 would occur tomorrow. A while later, I took a gander at the ChessBase site, saw "Thursday" and changed my post. On the other hand, the official site says they play tomorrow, and on the other other hand, the original schedule left a free day between games 11 and 12.

Anyone got a clue?

Chess, Like Love, Like Music, Has the Power to Drag Men Into Court
In an open letter to the FIDE President and the head of the "2006 Executive Committee", Kramnik's manager Carsten Hensel threatens/promises a lawsuit on his client's behalf. That my sympathies are with Kramnik should be obvious to anyone reading this blog the past couple of weeks, but I think this letter is a mistake for several reasons.

First, it's not going to change anything. Iljumzhinov isn't going to order them to replay game 5, and barring a religious conversion neither Danailov nor Topalov is going to turn it over.

Second, Hensel's letter strikes me as pre-emptive sour grapes in case of a Kramnik loss.

Third, the parties involved already knew/expected Kramnik to file suit afterwards, so why mention it again now? It's not going to distract Topalov; if team Topalov is as bad as the suit implicitly suggests, then this won't bother them at all. (And if it is designed to disturb them, then it's a step in an unsportsmanlike direction.)

Fourth, it's absurd to claim that "toiletgate" has harmed Kramnik's reputation; if anything, it has enhanced it! He has shown himself willing to stand on principle, to behave with dignity and competitive courage. It is Topalov's reputation that has been badly harmed, not Kramnik's. (At least within the chess community; I'm not aware of how the "civilian" world has seen the controversy, if at all.)

Fifth, it's the vain pursuit of an empty hope. As long as Kramnik keeps hope alive that he may yet get the lost point back, it may keep him from being fully focused on the match situation as it really is.

So my advice to Kramnik is to drop all the extracurricular activity until the match is over. Yes, the situation is unfair, but nothing has changed since you decided to keep playing with game 6. Just play. If you win, the lawsuits are unnecessary; if you lose, even winning the lawsuit will be empty.

Kramnik 5.5, Topalov 5.5
As usual, Topalov produced the game's first new move, but Kramnik achieved a more or less equal position without too much trouble. Topalov did enjoy a very small edge in complex ending, but his impatient 29.f5 compromised his pawn structure, deadened his light-squared bishop and turned the advantage over to Kramnik.

Kramnik played very well after that until move 40, when after a reasonably long think he decided on what appeared to be the second-best move. This led to an opposite-colored bishop ending with only nominal winning chances, and the game was soon agreed drawn.

That leaves us with game 12 on Thursday. If either player wins, that ends the match; if it's drawn, they move on to tiebreak games (unless by some quasi-miracle game five actually occurs).

The game, with my comments, can be replayed here.

Light Entertainment on the Day Off
Mondays are especially busy for me, but I'll offer a brief post to help tide readers over until tomorrow's game 11: a couple of ChessBase articles that present the world championship contenders in their own very different lights.

Here's a translation of a Topalov interview, in which, among other things, he praises his manager, who "won all legal battles", criticizes Kramnik, who "has never adhered to any principles", criticizes the ChessBase site and offers his own 9/11 conspiracy theory. (Ok, I made the last one up.)

Meanwhile, a far less pugnacious item covers the players' post-game 10 press conference. Kramnik strikes the right tone, psychologically speaking: he comes across as upbeat, confident, and amused by the opponent's shenanigans. Even if it's only an act, it's the right act!

Hans-Walter Schmitt on Topalov

Schmitt is the German tournament organizer responsible for the annual chess festival in Mainz (the event with the rapid and Chess960 world championships), and in an interview on the German-language ChessBase site, he makes three suggestions regarding Topalov. He

1) suggests that "the organizers of Wijk aan Zee, Morelia/Linares, Monaco, Dortmund, Mainz and Corsica" threaten to ban Topalov from their tournaments if he doesn't stop his unfair behavior off the board

2) suggests that "some of Topalov's top ten colleagues" reject invitations to the Sofia tournament

3) suggests that "a team of experts could investigate how it is possible that an experienced player no younger than 30 suddenly doesn't perform at his 2730-2740 Elo level any more but constantly plays 2800+ with remarkable streaks of victories". He goes on to point to Topalov's mediocre performances in the speed chess section of Monaco and his failure to play Anand in this discipline.

[Hat tip: ChessToday, which received the story from a comment here (search for "coreolarus").

I've wondered about Schmitt's third point myself. Topalov went wild in 1996, winning everything in sight, and made it to 2750 - and then never saw that rating again until 2004, I think, when he started an incredible run culminating with his current, imposing 2813 figure. (I'm also mystified by his seeming inability to put together a full tournament: how does he continually score around 50% for half a tournament, and then win practically every game in the other half, as if flipping a switch?)

This doesn't prove he's cheating, but it is surprising and remarkable. It's even encouraging: if one is willing to put in the work, even those "stuck" at a 2700 plateau (I hear an orchestra of tiny violins) can make further progress!

Barring real evidence that Topalov is cheating, I think Schmitt's third point is an overreaction, but barring a sincere and impressive apology from Topalov & Danailov after the Kramnik match (and preferably during it, but I wouldn't hold my breath), it would be nice to see some action on Schmitt's first two proposals.

Kramnik 5, Topalov 5
After "castling" the last two games (0-0), Kramnik bounced back with a match-tying victory in game 10 - though it might be more accurate to describe the game as a Topalov defeat. Kramnik came out of the opening, a Catalan, with a slight but usable edge. That advantage was being chipped away when suddenly Topalov made an outright blunder, leaving him down two pawns with an otherwise slightly inferior position to boot. Kramnik's technique was a bit cautious but certainly good enough, and now Topalov's momentum, psychological advantage and above all, match lead, have evaporated.

After two dreadfully played games this weekend, we remain tied. There are two games to go (not including tiebreak games); game 11 will occur (one hopes!) on Tuesday.

The game, with my comments, can be replayed here.

Topalov 5, Kramnik 4
It's not the result I hoped for, but Topalov deserves full credit for today's game, which was a complete massacre. Kramnik responded very poorly to Topalov's novelty, and quickly found himself in a prospectless position without space or counterplay, while Topalov enjoyed a powerful center, the two bishops, and a wide array of targets. A complete disaster for Kramnik, who had better pull himself together with just three games to play.

Kramnik 4, Topalov 4 (Updated!)
The "prevent defense" failed, as it almost always does (see the last sentence of the "prevent" link), and so both players are back to square one.

Kramnik, with White at last, was outprepared by Topalov in the Meran Defense, and quickly bailed out to an endgame with two rooks and a pawn against Topalov's rook and two knights (both sides had additional pawns). The position was probably approximately equal at the start of that ending, but not a safe equality for Kramnik. Unless he could find a way to maintain the initiative, Topalov's 3-2 advantage in pieces would tip the balance in his favor - and so it did.

UPDATE: The game, with my comments, can be replayed here.

Hensel: Prophylaxis or Paranoia?
Kramnik's manager Carsten Hensel has submitted a letter to the head of the World Championship Committee which states:

(1) He has been warned that the Topalov team might try to plant an electronic device in Kramnik's room in order to subsequently "prove" that he was cheating, and thus

(2) Hensel wants Topalov team members involved in the inspection process of Kramnik's rest area and bathroom to themselves be very carefully examined and supervised.

Sad to say, this seems like a plausible concern and a reasonable solution. Hopefully this wise pre-emptive move will reduce the possibility of a new, more or less artificially generated scandal's arising, but at this point it's hard to count on it.

Real Score Kramnik 4-2, FIDE Score 4-3 (Updated!)
Despite enjoying the pleasure of his third consecutive game with the black pieces and a new accusation from his opponent's manager, Kramnik not only drew with ease but had his opponent on the defensive for much of the game.

As Predicted, Danailov Strikes Again

Here's a delightful press release from Silvio Danailov mentioning - from purely mathematical interest, I'm sure - a set of "coincidence statistics":

Coincidence Statistics of the moves of GM Kramnik with recommendations of the chess program Fritz 9

Elista, October 4, 2006

After very detailed analyze [sic] of all games of the match we would like to present to your attention coincidence statistics of the moves of GM Kramnik with recommendations of chess program Fritz 9.

First game: From 75 moves: After the 12th move of Topalov Ba6, a novelty, from 65 remaining moves – 41 moves match with the first line of Fritz 9. (63% of matches)

Second game: From 63 moves: After 17th move, where the theory ends, from remaining 46 moves – 40 moves match with the first line of Fritz 9. (87% of matches)

Third game From 38 moves: after 10th move, when the theory ends, from 46 remaining moves – 40 match with the first line of Fritz 9. (86% of matches)

Forth [sic] game: From 54 moves: After 14th move, when the theory ends, from 40 remaining moves – 30 match with the first line of Fritz 9. (75% of matches)

Sixth game: From 31 moves: After 13th move, when the theory ends, from 18 remaining moves – 14 match with the first line of Fritz9. (78% of matches)

Thus, out of 5 games – 78% of GM Kramnik’s moves match with the first line of Fritz9.

Sincerely Silvio Danailov

Wow, conclusive proof, right? Not really. First, we'd need to confirm Danailov's claims. Second, we'd have to show that they're really statistically significant. For instance, I've played bullet games (without cheating, in case there are any smart alecks out there) with a higher degree of coincidence with my engine's suggestions than the Kramnik 78% figure. Sometimes the position is such that some move or series of moves is just obviously best (captures, recaptures and forcing variations are the most noticeable examples). Third, were these non-obvious, "non-humanish" moves that mattered? Fourth, did they further coincide with bathroom breaks? Fifth, what's the usual degree of coincidence between Fritz 9 and Kramnik's chess, especially when playing Topalov? Sixth, what about other super-GMs? Do they generate roughly similar coincidence numbers?

Is it impossible that there's something to Danailov's implicit accusation? No, and it's not impossible that Topalov is cheating during his bathroom breaks, either. But chances are this is just phase two of the Topalov team's psychological warfare, doubling as a defensive propaganda move against all the ill will that has accumulated against them over the past week.

I'm inclined to think the right thing for Kramnik to do is ignore this ploy, but if he does, Danailov will probably just increase the volume. Are there any good solutions for Kramnik, short of ending the match in three games by winning out?

Real Score Kramnik 3.5-1.5; FIDE* Score Kramnik 3.5-2.5 (Updated)
* I believe this abbreviates "For the Interests of Danailov Exclusively" or "For Impeding Danailov's Enemies," but I haven't been able to confirm this.

After Topalov's brilliant win in game 5, his turn with the White pieces proved an anti-climax. Kramnik equalized with complete ease, and will be well-rested for his turn with...the Black pieces again on Wednesday (thanks to ScottM for the correction). Presumably Kramnik will get reacquainted with the White pieces on Thursday - unless Danailov devises another ingenious protest.

Update: The game, with my comments, can be replayed here.

Kramnik-Topalov: Game Six is Underway
While continuing his protest of the forfeiture in game five, Kramnik has decided in the meantime to keep playing. This feels strange to me on more than one level (Trying to have his cake (the high moral ground) and eat it (winning on points) too? Giving himself an excuse to quit the match if things go sour? Letting Topalov get away with his team's illegal protest and the absurd Appeals Committee decision?), but hopefully we can just enjoy the remaining games without worrying about any further chicanery.

Kramnik-Topalov: Match Resumes Tomorrow?

If you look at this document, you might be inclined to think so, and that they will continue with the score 3-2 in Kramnik's favor. But I believe such a conclusion is based on a misunderstanding. It's not that the players - Kramnik in particular - have agreed to play; rather, FIDE President Iljumzhinov has simply decreed it.

Here's the key text from the announcement; decide for yourselves:

The FIDE President has made several proposals for further continuation of the match, which unfortunately were not accepted. After the detailed study of the current situation and the consultation with the FIDE Legal Advisor, the FIDE President decided:

Tomorrow, 2 October 2006, at 15.00, the 6th Game of the World Chess Championship Match Topalov-Kramnik with the score 3:2 in favour of Kramnik, will take place.

So unless Kramnik has done a complete about-face, and I have yet to see any confirmation that he has, I think the real headline is this: Kramnik-Topalov: Match Concludes Tomorrow.

Match news followers might want to check out ChessBase's "full crisis blog" and Bessel Kok's comments on the match. Predictably, both because he seems to be a decent man with common sense but also because he was Iljumzhinov's opponent in the recent FIDE elections, his view is that the protest was groundless and the match should resume with game 5. Sadly, it seems clear that that's not going to happen.

Kramnik-Topalov: The Holding Pattern Continues
There's not going to be a game today, either, as the negotiations continue. See here and here for the latest.

The bathroom issue has been resolved in Kramnik's favor, but now the big sticking point is Saturday's "game": Topalov wants to keep his free point, and Kramnik wants to continue from 3-1. What will happen? We shall see...
