Topalov scored his third win in his last four games, going through Carlsen like a hot knife through butter. With White in the suddenly popular Ragozin QGD, Topalov produced another of his trademark exchange sacrifices. According to the winner (
videos here), Carlsen had one chance to keep things interesting (with 16...Bd7), missed it, and quickly found himself in a hopeless ending.
Radjabov was just half a point back entering the round, but having the White pieces against Svidler only resulted in a very short draw. (Strangely, Radjabov is +3 -0 =2 with Black, but a comparatively dismal +1 -1 =3 with White.) Short, but very interesting. Let's start with this position:
Black is up a piece for the moment, and he can keep it, too, with
16...g5 - but he didn't. Why not? - why did he prefer 16...dxc3? It's clear that White has some compensation, but is it enough for the piece? First,
17.exf6 gxh4 18.Rae1+ Be6 19.Rf4 (threatening 20.Rxe6+ fxe6 21.Qg6+, winning)
19...Kf8 20.cxd4 Qc7 21.Rxh4 Qxc4 looks very good for Black.
The other capture looks much better:
17.Rxf6 gxh4 18.cxd4 h3 19.Raf1 Be6 20.d5 Qb6+ 21.R1f2 O-O-O 22.g3 and now both 22...Rd7 and 22...h5 lead to an unclear position. Rybka "thinks" Black is slightly better in each case, while the pride of Hamburg (Fritz 10) "thinks" it's equal. It's a mess worth analyzing for those who like this variation with either side.
The second interesting moment comes at the end of the game, which concluded with 19.Bg3:
As it turns out, this position was reached once before, and that was in a game between Kramnik and the very same Svidler from the 2005 edition of this tournament. Also a quick draw? No: Kramnik won in just nine more moves:
19...Be6 20.Rac1 Bxc4 21.Rfe1 Kd7 22.Re7+ Kc7 23.Rc7+ Kd5 24.Rd1+ Ke6 25.Rxc4 Rac8 26.Bc7 Kxf7 27.Rxc3 Rhe8 28.Rf3+ 1-0
So why the draw? Kramnik himself supplies the answer in his Informant notes (Informant 92, game 140): Black can improve with 19...Re8 with the idea that 20.Rac1 is successfully met by 20...Re3 21.Rfd1+ Ke8, or 20.Rfd1+ Bd7 21.Rac1 Re3. In both cases the Black king manages to avoid the dangers that befell him in the actual game. The result is that the opposite colored bishops become the most important factor, and here they should lead to a comfortable draw.
This leads to a new question, of course: why did Radjabov play this way? Why burn a White when contending for first place in one of the most prestigious tournaments in chess? I haven't a clue, but if Radjabov has addressed this question somewhere and any of you come across his answer, please let me know.
In other games: Motylev-Kramnik was a perfunctory draw, as expected, but van Wely-Aronian was a real comedy of errors. The position was roughly even through White's 30th move, but then 30...Rxf3? instead of 30...Rd3 landed him in a lost position. Happily for him and for lovers of swindles (but not for his opponent, naturally), van Wely fell into a "cheap, cheap trap" (as one of the GMs watching online put it) in this position:
It's White to move and just about everything wins (or more accurately, maintains the winning position). But a won position isn't a win; one must
do something. Well, how about this?
38.Rh5(??)
If Black trades rooks, White wins the h-pawn and then the game, and if the rook moves away, White again wins the h-pawn and the game. It all seems very nice and tidy, but there's just one problem...
38...Rxd1+!! (the second exclamation mark is for the move's emotional impact)
39.Kxd1 Kf7 (the point!)
Black threatens 40...Bxg4+ followed by 41...Bxh5, and while White can save the rook, he can't save enough material to have winning chances, and the game was agreed drawn after
40.Rxh6 Bxg4+.
Karjakin-Anand was a typical exercise in modern chess preparation: Anand had prepared everything through Black's 29th move, and on move 30 Karjakin went astray. Anand criticized his subsequent technique, but still managed to bring in the full point.
In the day's other games, Tiviakov-Navara was a non-game, drawn in 18 moves, while Shirov pushed hard against Ponomariov but couldn't quite achieve his second straight victory.
Standings after Round 10:
1 Topalov 7½
2 Radjabov 6½
3-6 Anand, Aronian, Kramnik, Svidler 6
7-8 Karjakin, Ponomariov 5
9 Navara 4½
10-11 Motylev, Tiviakov 4
12 van Wely 3½
13-14 Carlsen, Shirov 3
Pairings for Round 11: (Friday morning; Thursday was a rest day.)
Navara - Motylev
Ponomariov - Tiviakov
Anand - Shirov (No longer a virtual freebie: Shirov has played well the last four rounds.)
Aronian - Karjakin (A must-win for Aronian, and the timing is good: Karjakin has lost his last two games.)
Carlsen - van Wely
Svidler - Topalov (A huge game if Svidler can win.)
Kramnik - Radjabov (Will the KID finally meet its come-uppance?)
