Since we have a short draw in the Aronian – Kramnik game ended in a quick draw, I will do commentary on the Grischuk – Svidler game now.
GM Grischuk (2726) – GM Svidler (2735) [D43]
19.09.2007
1.Nf3 d5 2.d4 Nf6 3.c4 c6 4.Nc3 e6 5.Bg5 h6 6.Bh4 dxc4 7.e4 g5 8.Bg3 b5 9.Be2 Bb7 10.h4 g4 11.Ne5 h5 12.0–0 Nbd7 13.Qc2 Nxe5 14.Bxe5 Bg7 15.Bg3 Qxd4 16.Rfd1 Qc5 17.Bd6 Qb6 18.a4 a6 19.e5 Nd7 20.a5 Qa7 21.Ne4 (I evaluate this as a little better for Black. White does have some compensation but a pawn is still a pawn.)
21…c5 22.Ng5 Nxe5 23.Bxe5 Bxe5 24.Bxc4 (White is sacrificing a lot of material but he has compensation because the Black King is quite vulnerable.)
24…bxc4 25.Qa4+ Kf8 26.Rd7 Bd5 27.Rd1 (If White plays 27.Rxa7, Black will respond with Rxa7 and Black is better. This is now quite interesting. Black cannot move the Queen away because Rxf7+. So Black is stuck. This is an amazing position. Black may have to play 27…Bd4 because not much else works. Black is almost in zugzwang. This has to be the most exciting game so far in this world championship. If 27…Bxb2 28.R1xd5 exd5 29.Qc6 and White is much better because of the potential attack on the f7 pawn.)
27…Bd4 (Basically the only move. OK. Now what will White do now. Black is fine if White captures the Black Queen. So what else? If 28.b3 cxb3 29.Rxa7 Rxa7 30.Rxd4 cxd4 31.Qxd4 +-. Another line is 28…Qb8 29.Rxf7+ Kg8 30.bxc4 g3 31.cxd5 gxf2+ 32.Rxf2 Bxf2+ 33.Kxf2 Qb4 34.Qc6 Qxh4+ 35.Kg1 Rf8 36.Qxe6+ Kg7 37.Qe5+ Kg6 38.Ne6] 29.Rxa7 Rxa7 30.Rxd4 cxd4 31.Qxd4 =)
28.Rxa7 Rxa7 29.b3 Kg7 30.bxc4 Ba8 31.Qc2 = (31…g3 is possible and probably is the best move.)
31…g3 32.Rxd4 cxd4 33.Qe2 gxf2+ 34.Qxf2 Rd8 35.Qg3 (White should be able to hold this with ease. Still an amazing game!)
35…Kf8 36.Qe5 Ke8 37.Nxe6 fxe6 38.Qh8+ Ke7 39.Qg7+ Ke8 40.Qh8+ Ke7 (41.Qh7+ Ke8 42.Qxa7 d3 43.Qxa6 Ke7 44.Qa7+ Rd7 45.Qc5+ Rd6 46.Qg5+ Kd7 47.Qd2 and White is better. But this is extremely difficult to calculate.)
41.Qg7+ 1/2
My Fritzy says -+1.79. (After 21.Ne4)Thats more than a little better. Seems that Svidler has real winning chances…
and two pawns are still two pawns 🙂
24.Lxc4 bc? 25. Da4+ and Dd7
yes, but proggies are the most accurate defenders, unlike humans they do not feel pressure, they just calculate.
Susan would you mind to do some more analysis on this game, the position is so imbalanced and extremely interesting. PLEEEAAAAAAAAASSE 🙂
I may add here one E and one A to my preblogdecessor 😉
Susan, would you mind to change the title to Grishuk – Svidler?
What are the development plans for Moro? How should he ativate his bishop b7 , via a6 or c8? Te8-e5 What else?
What does Fritzi say now on Grishuks position?
24. Bxc4 is great! some human chess finally…
Depends on which silicon monster you asked.
ranging from -3.xx to +0.15
And btw. the title is just wrong, the game is
Girschuk vs. Svidler (NOT Morozevich)
Moro 23.- Bxd5 24.Bxd5 Te5 then 26.Nxd6 + ?!
27. Rd1 — why didnt white take the black Queen??
Uh, 23..Bxd5 24.Bxd5 Re5 25.e4 1-0 is probably not the best plan for black.
Grischuk’s 27th was interesting.
Grischuk can always take the queen later. Svidler isn’t going to give up f7, and there’s no way for him to force Grischuk to part with more than he’s already sacrificed.
If the black Quee retires from the 7th rank , then white will send the king to sleep on this line with txf7 and Dd7 i guess. So look at this boy , he is catching up with Vishi.
nice attacking ideas out of nothing, impressive!
To continue, maybe Grischuk is preparing Nxf7 without allowing Bxb2 as a response?
Td1 is as well a psychological move saying : hey guy , i don’t need your queen , i catch your king!
“27. Rd1 — why didnt white take the black Queen??”
The queen doesn’t run away. And if she does though (Qb8) Rxf7+ and Qd7 crushes black.
Grischuk and Morozevich (I still don’t understand his exchange sacrifize) are fighters and they are good for this tournament…. they are my new favourites. 🙂
T1xd5 is hanging in the air. The Bishop on d5 is the only white square protector. After he has gone the white queen elapse on c6 or via c2 to f5 etcetc
if 27…Qb8, then 28.Rxf7+ 28…Kg8 29.Rxd5! exd5 30. Qc6!.
told you… Bxc4 was great human move!
Well, playing R1xd5 is all well and good, but if you’re going to follow up with Qc2-f5 then you’ll need to take on a7 first, which rather defeats the point… and after Qc6, doesn’t black have time for ..Kg7, ..Qxd7, and ..Raf8?
Susan, may I ask what’s wrong with 27..Bxb2 here? I’m sure there’s a refutation, but I can’t see it 🙂
Jochen
The Queen is going nowhere and Rxa7 Rxa7 might even favour Black.
Dunno who asked it, but Bxb2 looks very dangerous R1xd5 and Qc6 coming.
Svidler must really feel like dancing in a mine field
now taking the queen and b2-b3 since the pawn cannot be taken due tthe double attack on both rooks via d4 sac
I dunno if that works, Rxa7 Rxa7 b3 c3 and it might be difficult to catch that nasty pawn.
Not sure if it works, but the idea looks interesting if it works and Grischuk finds it, he’ll be the Tal of the day 🙂
“Jochen
The Queen is going nowhere and Rxa7 Rxa7 might even favour Black.”
I did never say anything else, did I?
(I just told ano 5:03 why white did not have to take the queen immediately after Bd5.)
Greetings
on b3 , c3 we would have sac’fied our rook on d4
ah my bad, thought it was question and not the beginning of an answer to an question, should really read full posts before answering, even if it is just internet, anyway my bad – sorry.
Maybe we get a 2nd worldchamp-Boris as he continues his good play?!
Buenas noches desde España, desde Cáceres (www.ateneodecaceres.es/ajedrez)
¿Qué tal 31…g3?
No problem, ano 5:44. 🙂
“41.Qh7+ Ke8 42.Qxa7 d3 43.Qxa6 Ke7 44.Qa7+ Rd7 45.Qc5+ Rd6 46.Qg5+ Kd7 47.Qd2 and White is better. But this is extremely difficult to calculate.)”
Why should black play 43. -, Ke7?
Doesn’t 43. -, d2!? force white to give perpetual?
With that strong passed pawn black can sac another pawn (e6)…
Am I wrong?
what was wrong with 36 Nh7 after
35 Kf8? It seems alright to me!
In the line 41.Qh7+ Ke8 42.Qxa7 d3 43.Qxa6 now 43… d2 should be draw.
i agree with jochen…
In jochen’s line, I think white can get the queen to d1, but then black should be able to play Bc6-Ba4
43…I don’t know if it holds or not but I would try. But I can’t fault anyone who played such a gutsy game 🙂
My brain hurts from analyzing 4 games 🙂
Best wishes,

I think Grischuk had a win.
36.Nh7+ (instead of 36.Qe5) Ke7 (or 36…Ke8. 37.Qg8+ Ke7 and the same as the main variant)
37.Qg5+ Ke8 (37…Kd7.38.Qc5 with 39.Nf6# or 39.Qa7)
38.Qc5 Re7. 39.Nf6+ Kf8 and even 40.Ng8 could be enough
40.Qh5 should win too
