9/25/2012 – Alexander Grischuk won a fine game against Shakhriyar Mamedyarov, one that both our GM commentators, Alejandro Ramirez and Daniel King, have chosen to show us as the game of the day. The other really interesting game was Boris Gelfand vs Wang Hao. Just when the Chinese GM seemed to have saved a tough rook ending he blundered into a mate in one. It was all captured on video!

Nakamura-Topalov: White gets very little fr0m the opening
and despite being marginally better the entire time, Hikaru is never able to
put Topalov against the ropes. Draw.
Kasimdzhanov-Dominguez: Kasimdzhanov essays the same line
he used against Leko in round 1. He obtains a superior pawn structure but very
little else besides that, and the bishop endgame is easily held by Dominguez.
Draw.
Giri-Ivanchuk: In a rather strange game (Giri made over a
third of his moves with his queen…) the players agreed to a draw in a
opposite colored bishop middlegame that could only favor Black, even if it was
rather marginal. Draw.
Leko-Adams: This game isn’t making any top 100 most
exciting games ever played lists. The draw was seen coming from a mile away.
Draw.
Gelfand-Wang: After a questionable pawn push on the queenside,
Wang Hao starts suffering. Through some resourcefulness, the Chinese player
escapes into a pawn down endgame. The battle is between Gelfand’s knight,
rook and three pawns against Wang Hao’s bishop, rook and two pawns. Normally
an easy draw, Black’s king is also against the ropes, being cut off on
the seventh rank. After the minor pieces are swapped, it still seems like the
game will end in a draw – but Wang Hao commits a serious mistake in 49…
f5+? Gelfand doesn’t capitalize, instead opting for a somewhat awkward
rook maneuver. Tragically, Wang Hao blunders yet again, this time into a simple
mating net. Gelfand wins. 1-0.
Video stream of the whole game – jump to 04:40:50 in the video to
see Wang Hao, after a long think, play 54...Re4, to which Gelfand responds,
after a few seconds, with 55.Rd1.
But after around a minute of thought Wang plays 55...Kh7??
You see it, don't you? Gelfand does, and replies with 56.Kf7...
Wang can only laugh at himself, as he sees that nothing can now stop Rh1 with
mate. 1-0.
Interview with Gelfand and Wang Hao. You decide whether the Chinese GM is
laughing or crying
when he describes the blunder and how he forgot that the f-pawn covers the g5
square.

this specific position has not been seen particularly often. 11.Bc2exd412.cxd4Bg413.h3Bh514.g4The game Vallejo-Cabrera from 2005 featured
the very logical Nf1.14.Nf1d515.e5Ne416.Ng3Nxg317.fxg3Nb4∞14...Bg615.a3h516.g5Nh717.Nf1Qd718.Kg2d519.e5Bxc220.Qxc2g6Black trades the light squared bishops, and is using his pawns and pieces to
create a blockade in the weakened squares. If he is successful, White's space
advantage will be irrelevant and an eventual break on c5 will come with a lot
of power.21.Be3Nd822.Rac1Rc822...Ne6?!23.Qc6! Allows White
his own strong blockade.23.Ng3c6?Maybe the losing mistake, even though
it does not seem so.23...Be7!Was key - the point being24.Nh4runs
intoNxg525.Nxg625.Bxg5Bxg526.Nxg6Bxc1is greedy, but maybe it works.26...Re6!25...Qxh3+24.Nh4!A very strong move. Grischuk eyes
the g6 pawn as a perfect place to sacrifice his knight. He is taking advantage
of the fact that at the moment Black's pieces are uncoordinated, and if the
pawns start rolling there is little Mamedyarov can do about it.Ne625.Nxg6fxg626.Qxg6+Ng727.Qh6! Grischuk is amazingly precise. Taking on h5
was natural and possible, but nowhere near as strong. This strange looking move
is threatening g6, after which the knight on h7 is lost (!). There are also
no strong discoveries with the knight on g7!Nf527...Be728.Nxh5Nxh529.Qxh5and the bishop is misplaced on e7.28.Qxh5Nxg329.Kxg3It's possible
to say that taking with the f-pawn and the king were both possible, and the
difference was mainly stylistic. I do believe taking with the king is stronger,
though. Now White's plan is easy, trade queens and push pawns.Bg730.Qg4Nf831.f4c532.Qxd732.Rxc5!Rxc533.Qxd7Nxd734.dxc5+-32...Nxd733.dxc5Nxe5Black is forced to sacrifice before he gets steamrolled. The
variation with Rxc5 did not allow this.34.fxe5Bxe5+35.Bf4Bxb236.Rxe8+Rxe837.Rc2Although Black has material equality (after recuperating his pawn
on a3), the advanced nature of the c-pawn renders his position hopeless.Bxa338.c6b439.c7Rc840.Rc6!b341.Rxa6?!This move seemed very strange
to me, even though it doesn't spoil anything just yet.41.Rb6b242.g6d443.h4d344.Kf3d245.Ke2leaves Black in a state of Zugzwang.41...Bc542.Ra5Bb643.Rxd5Bxc744.Bxc7Rxc745.Rb5Kg746.Kg4This endgame is
very basic for any grandmaster. The b-pawn has to fall to prevent the rook checking
from the side, and when that happens it's super easy. Mamedyarov committed one
serious mistake and a powerful piece sacrifice by Grischuk devastated his position!1–0
