The FIDE Candidates in London round 7 saw all four games drawn but not without chances in three of them. Magnus Carlsen wound up the tension against Teimour Rajdabov creating a very sharp position where he was eventually going to allow a strong kingside attack. Things went wrong for him but probably not quite to the extent that the computers said. Carlsen was well prepared to sacrifice the exchange as he did and he did get more than enough compensation. Carlsen thought he ought to be much worse but only by slow play with something like 25...Be7. Rajdabov's 25...f2 looked like the winning idea but Carlsen found a lot of counterplay. A fascinating yet flawed game that shows just how confident Carlsen is in his own abilities and perhaps provides a better insight into the way Carlsen tries to drag his opponent into trouble than games where this works out. Levon Aronian played very solidly against Alexander Grischuk and eventually found a way to get a nasty initiative. Aronian was further encouraged by Grischuk's time pressure but it was precisely then his advantage entirely disappeared. Boris Gelfand and Vladimir Kramnik discussed a classical isolated pawn position. Kramnik started to become dissatisfied with his position and his 18...Ne8 was a mistake but one that Gelfand couldn't calculate to the end. 19.Nfg5 is winning according to the computers and Gelfand could have played it and tried to make it work move by move but he retreated and the game fizzled to a draw. Vassily Ivanchuk and Peter Svidler discussed a theoretical line in the Scotch and after a short period of potentially interesting play the game was agreed drawn in a position where neither side could make progress. Round 7 Standings: Carlsen, Aronian 5pts/7. Kramnik, Svidler 3.5pts, Grischuk, Radjabov 3pts, Ivanchuk, Gelfand 2.5pts. Round 8 Sun 24th March 2013: Carlsen-Aronian ("I think it's going to be a big game tomorrow. If either of us wins they're going to be big favourite." - Carlsen), Radjabov-Gelfand, Grischuk-Ivanchuk, Kramnik-Svidler.

7...Ng6 8.exd6 Bxd6 9.Nc3 e5 10.Re1 0-0 11.d3 f5 12.Ba3 Be6 13.Na4 Qe7 14.c4
[14.Bb2!? Might be a way to cut across Rajdabov's plan. 14...Bd5 15.c4 Bxf3 16.Qxf3]
"Somehow everything came unexpectadly for me." - Radjabov who spent a lot of time here trying to get Nf4 to work.
[15...Nf4 16.Qe3 Rf6 (16...e4 17.dxe4 fxe4 18.Qxe4 Qf6 19.Bxc5 Bf5 20.Qxc6 Bh3 (20...Nh3+ 21.Kh1 Bxc5 22.Qxc5) 21.g3 Nd3) ]
16.Qe3 f4!? 17.Qe4 Kh8 18.Rad1?!
Did you expect an exciting game today? "I didn't want it to be this exciting. I think from the opening it's fairly unbalanced so it's probably going to be some fireworks eventually." - Carlsen. "Also in general I agree, the position is really unclear black has their trumps, white has these trumps with c5 weakness but black has counterplay on the king's flank and it's very tricky. Of course at some point it's clear at some point white will take some pawn and black will just sacrifice everything on the kings flank. Nh4xg2, f3 and later on you can see if there is a win for any side but certainly it's not an equal line or drawish or something it's really unclear." - Rajdabov.
[18.h3 is not the kind of move that white wants to play as it weakens the kingside ("an incredibly ugly move" - Svidler) but it just seems necessary here. "If I go h3 then it's a normal game." - Carlsen. 18...Rf5 19.d4!? "It's not clear but it's definitely much better than what I did." - Carlsen. (19.Nc3 Rh5 20.Rad1 Nh4 21.Nxh4 Rxh4 22.d4 f3 23.Qxf3 cxd4 24.Bxd6 Qxd6 25.Ne4 Qg6 26.Nc5 Rxh3 27.Qe4 Qxe4 28.Rxe4 Rh5) ]
18...Bg4 19.Rd2 Bxf3 20.Qxf3 Nh4 21.Qe4 f3 22.g3
"Here I was thinking there was no special danger because I can sacrifice the rook when the knight gets to g2. That was my plan." - Carlsen.
[23.Red1? Qe6 24.Kh1 Qh3 and Rajdabov revealed he was thinking about all sorts of endings when he missed something trivial. 25.Rg1 Rf6 26.Rxg2 fxg2+ (26...Qxg2#! is by far the best.) 27.Qxg2 is indeed equal.]
[23...Qd7 24.Re3 Nxe3 is another try. 25.fxe3 Bc7 26.Bxc5 f2+ 27.Rxf2 Rxf2 28.Kxf2 Qxd3 29.Qxd3 Rxd3 30.Ne4 "and it's not a big deal" - Carlsen.]
[24...Qh6 was also considered by Radjabov but he didn't know whether it was better.]
"Here somehow I was certain 25.f2 was the move." - Rajdabov. This move looks so tempting but it seems just not to be the best. White may be worse or even losing but that win doesn't appear to be coming fast. Carlsen has got his pieces and pawns well coordinated and the long term weaknesses in black's position are a factor.
[25...Qd7!? 26.Nd1; 25...Be7!? 26.Nd1 "Just to play slowly somehow because I don't know what I can do." - Carlsen. 26...h5!? (26...Qh3 27.Bb2 Kg8 "Kg8 is too much maybe." - Rajdabov who didn't have a clear idea how to go about this even after the game. (27...Bg5 28.Ba3 "Somehow you should consolidate and... I'm not sure I even want to take on e5" - Carlsen who was worried about opening lines.) ) 27.Bb2 Rf5 28.Nf2 Rdf8 29.Kf1]
26.Rxf2 Rxf2 27.Kxf2 Rf8+
[27...Qh3 is an alternative but it doesn't seem radically different.]
[28.Kg1 was the line Rajdabov concentrated on when most probably it is just winning for him. 28...Qf6 29.Qg2 e4]
[28...Qf6 29.Qg2 e4 30.Nxe4 Qa1 31.Nd2 Qxa2?! (31...Be7 32.Qh3 Qxa2 33.Qd7 Qxa3 34.Qxe7 and again a draw should follow.) 32.Qxc6 "and good luck to win this." - Radjabov.]
"And then suddenly I didn't find anything which maybe means there is nothing." Rajdabov.
29...Be7 30.Ne4 Qg4+ 31.Kd2 Qh3 32.Ke2 h5 33.Bb2 Qg4+ 34.Kd2 Qh3 35.Ke2 Qg4+ 36.Kd2 Qh3 37.Ke2 1/2-1/2

12...cxd4 13.Bxd4 Be7 14.Qd3 d6
Aronian wondered afterwards if this was the most precise.
After a solid opening Aronian said that "with Qc3 I made it more interesting."
"I tried to make things unclear but Levon found a very strong plan with 19.b5 and 20.c5 and after it I had to defend." - Grischuk.
16.Be3 Nd7 17.Rfd1 Rc8 18.Rac1 f5 19.b4 Kh8 20.c5! bxc5 21.bxc5 e4 22.Nd4 Nxc5 23.Nb5 Qb6
This was a good move. - Aronian.

"I think Levon played very well, I think pretty much perfectly until some moment." - Grischuk
[24...Qb7 25.Rb1 Nd3 26.Qe6 and black is lost.]
Aronian agreed he might have gone astray. He thought this might might be tricky for Grischuk in time trouble. "Sasha proved it's his kind of position and he played very well." - Aronian.
"After 26.Na4 a5 it should be a draw." - Grischuk.
[26.Nd5! was best here according to Grischuk. 26...Bg5 27.Bxg5 Qxg5 28.Nf4 Qf6 29.h4 very unpleasant for black. 29...g6 (29...h6 30.h5 Kh7; 29...Rcd8 30.h5 white is almost winning according to Grischuk.) ]
26...Nxa4 27.Qxa4 Rxc1 28.Rxc1 a5 29.Qb5 h6 30.Rd1
"I'm thinking Rd1 is a bit stupid. I was getting too comfortable here and then I realised the advantage is gone." - Aronian.
[30.a4!? looks better than the game according to Aronian.]
30...Bg5 31.Bb6 Qb8 32.a4 f4 33.h4
"Here already I have no problems." - Grischuk.
34.exf3 exf3+ 35.Kh2 Bf6
"I should not lose with such bishop, with such king." - Grischuk.

Of course Kramnik didn't want to do this and understood the risks.

Gelfand spent almost all his remaining time here trying to work the knight out to a win. He couldn't see his way to the end. It seems the computers think he's winning but it really isn't that simple.
[19.Nfg5 seems the better of the two knight moves but both are promising. 19...g6 (19...h6 20.Qh5 hxg5 21.Nxg5 Nf6 22.Qxf7+ Kh8 23.Nxe6 Qg8) 20.Nxf7 Kxf7 21.Ng5+ Kf6 22.Qxe6+; 19.Neg5 h6 20.Bg6]]
