10/7/2011 – It was a round full of tough chess, and fascinating games for all tastes. The first game to finish was Anand against Nakamura in a Ruy Lopez Berlin that went the distance. Aronian found himself suffering throughout the game against Carlsen though he survived. Vallejo beat Ivanchuk, when the latter faltered in time trouble. Illustrated report with video and annotations by GM Romain Edouard.

The first leg of the Grand Slam was staged in São Paulo, Ibirapuera
Park, from September 25th to October 1st, the second leg takes place in Bilbao,
Alhóndiga, from 5th to 11th October. Tournament system: double round
robin with six players over ten rounds. Time control: 90 minutes/40 moves +
60 minutes + 10 seconds/move starting with the first move. Games begin at 16:00h
local Spanish time (10 a.m. New York, 18:00h Moscow).
If anything, the tournament has been anything but predictable, and the seventh round merely compounded that. With the world's top three playing, who would have expected Ivanchuk to just run away with it, yet that is pretty much what he has been doing.
Leontxo García leads the post-game interview with Anand
Anand met Nakamura for the second time, and faced Hikaru's Berlin, a very tough nut to crack. The World Champion was hard pressed to do so, and despite gaining an extra pawn in the latter stage, it was impossible to work it to his advantage.

keep all pawns:Bf524.Nd1!The c2-pawn is untouchable. But White's
knight is still far from the f4/h4 squares, and I believe Black should hold
just playing passively. For ex:Be624...Bxc2?25.Ne3Bf5The only move.
26.Ng2!±25.Bc1b6and Black will face26.Ne3by playingBf7
or26...Rg5!?27.Ng2Ne828.Nf4Rg5and I don't see how White can get
more than some strategical draw. Black's rook still has many squares,
especially f5.23...Bf524.Nd1Bxc225.Ne3Bd326.Ng2Ne6Black had to
give up the h-pawn, which is a good achievement by White (by far worth the
c2-pawn). Even so, Black is up a pawn, though I think the position is a dead
draw. White cannot risk too much on the kingside since he's a pawn down, and
Black cannot insist either, since White's majority is simply stronger than
Black's. Furthermore, White is simply much more active. My feeling is that the
position is equal.27.Rxh5Rg728.Bc3Ke729.Rh6Rf730.g4Bb131.a3f5
A drawish move, and though he is not worse by any means, Black can never hope
for more.32.g5!Giving a second pawn, but White clearly has enough
activity to draw.Nxg533.Nf4Ke834.Rg6Nh735.Rg8+Rf836.Rg7Rf7
Naka's famous comment after the game, "Thanks to Kramnik I was able to just
play something silly like the Berlin and draw against the World Champion
relatively effortlessly." actually says much : )½–½
Aronian played a creative game against Carlsen, but when facing such a player, one had best be very well-covered to not find one's inventiveness the cause for one's demise. That seemed dangerously close to happening, as a hidden move missed by Levon left him with a very unpleasant position to defend. Despite having to suffer for the second time straight, he also avoided disaster once again.

reference!c5!?Grunfeld-like! Only Black's g7-pawn breaks the illusion. Of
course, it is normal to react in the center when you are attacked on the
kingside. Otherwise White is going to play g4 next, which is very unclear,
though I will not try to guess Aronian's preparation!9...Nd710.g4g611.cxd5exd512.h5g513.Bd3Bg714.Bf5Re815.Kf1Nb616.Nd2Bxf517.gxf5Nc818.Ne2Bf819.Kg2Bd620.Nf1Qf621.Qd3Bc722.f3Nd623.Neg3Rad824.b3g425.f4Kh826.Rc2Re727.Kg1Rde828.Rhh2Bb629.Kh1Bc730.Rhg2Rg831.Kg1Bb632.Kh1Ne433.Kg1Nd634.Kh1a635.Rh2Ba736.Rhg2Ne437.a4Bb638.Nxe4dxe439.Qc3Qxf540.d5+Kh741.Qb4Bd842.dxc6Qxh5+43.Rh2Qa544.Qxa5Bxa545.Ng3Re646.cxb7Rb847.b4Bb648.a5Bxe349.Rc7Rf650.Rhc2Rxf451.b5Rf652.Kg2axb553.Nxe4Re654.Nc5Bxc555.R2xc5b456.Rb5Kg657.Rc81-0 (57) Botvinnik,M-Ragozin,V Moscow 194410.dxc5Na611.cxd5Nxc512.Bc412.Qd2should be the only move to try something,
but it really looks like a "good Grunfeld" to me: not even the kingside is
weakened with a move such as ...g6. For example:Bxc312...a6!?13.Qxc3Ne414.Qb4Qxd515.Rd115.Bc4Qd615...a5!is drawish.12...exd513.Nxd513.Bxd5Bf514.0-0Bd315.Re1Bxc316.Rxc3Qxd517.b4Ne418.Rxd3Qxa2=13...Bxb214.Rc2b515.Be2Na416.Rc7?!Aronian continues
creatively, but Black has a brillant refutation.16.0-0a6and Black is
more than fine.16...Be617.Ne7+Kh818.Qc2Bc3+19.Rxc3Qa5!

Life tends to balance things out, and this game did just that at Ivanchuk's expense. In the sixth round, Vallejo had had a large advantage against Aronian, and was very close to beating him though the path to victory eluded him. This time, he merely had a minor advantage against the tournament leader, yet Caissa saw fit to reward him as Vasily tripped fatally in time trouble.
Vallejo once again scores and has almost rejoined the others

1.Nf3Nf62.c4g63.Nc3d54.cxd5Nxd55.h4Nxc36.bxc3h67.e4Bg78.d4c5We reach a normal Grunfeld setup... with h4 and ...h6 included.9.Bb5+9.Rb1would be like the main line, but my feeling is that the "h4-h6"
difference cannot help White.9...Nc610.d5Qa511.Rb1a612.Bxc6+bxc613.0-0Bg4Till there, things went more or less normally.14.d6!?14.dxc6Rc8is about equal.14...Rd815.Bf4exd615...0-016.dxe7Rxd117.exf8Q+Kxf818.Rfxd1Kg8is proposed by the engine, but since I doubt Black
has any winning chance here, it's better to go for the text move.16.Bxd6Bf816...Bxf317.gxf3Be5?!18.Rb8!Rxb819.Bxe5Rd820.Qc1is
unpleasant for Black.17.e5Bxd618.exd60-019.Qd2Bxf320.gxf3Rd721.Rfd1Rfd822.Qxh6Qxc3?!A bit over optimistic. Now Black will have to be
careful.22...Rxd623.Rxd6Rxd6seems like a dead draw to me, though I
might be missing something.23.Qf4c424.h5Qg7?!The beginning of
Black's problems.24...Qa5(or maybe even 24...Qh8!)25.hxg6Qh5should
be a draw, since Black's pieces are going to get free. Still, this is already
a purely computer defense, even if it is admittedly not entirely anti-thematic.
25.Rb6Rc825...Kh7!?might be a good defensive move. I cannot see a
good path for White:26.Rxc6gxh5+27.Kf1Qg628.Rd528.Qxc4Rxd629.Rcxd6Rxd630.Rxd6Qxd631.Qxf7+Kh6should be drawn.28...Qb1+29.Kg2Rg8+30.Rg5Rxg5+31.Qxg5Qg632.Qxg6+Kxg633.Rxa6Kf634.Rc6Ke635.Rxc4Rxd6with a probable draw.26.h6Qc3?26...Qf8was necessary.27.Rxa6c328.Qc1c229.Qxc2Qxh6and White is better, though Black has
good chances to hold.27.Rd4?!27.Kg2!Kh728.Rd4+-27.Rb4!?The idea of course isQxb4??28.Qf6and mate.27...Qe1+28.Kg2Qe6Black's only move.29.Rxa6c330.Ra3Rcd831.Rxc3Rxd632.Rxd632.Rcd3seems better to me:Rxd433.Rxd4Ra834.a4and Black still has problems to solve, though the
position is far from clear.32...Qxd6?32...Rxd6!should hold:33.Rc533.a4Rd534.Re3Qf5=33...Qf634.Qxf6Rxf635.Kg3Rd6and
Black will stop the a-pawn, or at least keep the c-one. I guess it's an easy
draw.33.Qxd6?!33.h7+!Kg733...Kh834.Qxf7Rf835.Rxc6Rxf736.Rxd6+-34.h8Q+Kxh835.Qxf7Rd736.Qe8+Kg737.a4and I don't think
Black can draw this!33...Rxd634.a4Kh7?34...Rd535.Rxc635.Ra3Ra536.Kf1Kh737.Ke2Kxh638.Kd3Kg539.Kc4Kf440.Kb4Ra641.Kc5Ke5!and White cannot make progress. This setup is very
important.35...Ra535...Rd4!?should also be a draw.36.Rc4Kh737.Kf1Kxh638.Ke2Kg539.Kd3Kf540.Kc3Ra841.Kb4Rb8+42.Ka3Ra8and I
believe the endgame is drawn. I took a bit of time to look a bit deeper, and I
believe White has no way to advance his pawn. Actually, there might be clever
plans like43.Rc7f644.Rc6g545.Rb6in order to prevent Black's king
from going to f4 and take the pawns, but even after a waiting move likeRa7
I cannot see a plan for White, since46.Kb4is met byRf7!after what ..
.Kf4 is a threat and White's rook is no longer able to defend; White can, for
example, play47.Kc5in order to try to advance, but afterKf448.Rb3Rc7+Black will take the f2-pawn, sac the rook against the a-pawn, push and make a
draw. To be more precise:49.Kd6Rc250.Ra3Rxf251.a5f5!51...Rh2??52.a6Rh853.Ke6!+-52.a652.Ke6Re2+53.Kf6g4=52...Rd2+53.Ke7Rh2=35.a5Kxh6?!35...c5was probably the only way but after36.f436.Ra3?!c437.f4Ra638.Kf1Re639.a6c3=36...Ra636...Kxh637.Ra3c438.a6c339.a7c240.a8Qc1Q41.Qh8#37.Rxc5Black got a much worse
version than 34...Rd5, which I guess should be lost. Still:36.a6Now the
game seems to be over.c536...Rd537.Ra3Rd838.a7Ra839.f4and White
will just bring his king to the queenside and win:Kg740.Kf3Kf641.Ke4Ke642.Ra6Kd643.Kd4and zugzwang later on...37.Ra3Rd838.f4Kg739.Kf3Kf640.a7Ra841.Ke4Ke642.Ra6+Kd743.Kd5Kc744.Kxc5Kb745.Kb5!Rxa745...Kc746.Rf6+-46.Rxa7+Kxa747.Kc61–0
