In an important day for the tournament Hikaru Nakamura defeated Alexei Shirov in a Sicilian to move within half a point of the formerly runaway leader. Magnus Carlsen beat Vassily Ivanchuk in a poor game where the Ukrainian blundered very early. Nigel Short came within an ace of defeating Vladimir Kramnik's Petroff Defence but couldn't win the technical ending.

Round 7 report, mostly by Michiel Abeln but additional reporting by Mark Crowther.

The First few hours of round 7 were not very exciting. Van Wely and Shirov made a quick draw, Van Wely being tired of losing, and Karjakin needing his energy to fight a cold. It also quickly became clear that Ivanchuk had one of his off-days, quickly losing a pawn. He then sacrificed his queen, probably realizing that being a pawn down he would not survive, but the sac really didn’t make any sense and Carlsen won easily.

Dominquez and Smeets played a sharp Sicilian Najdorf, where Smeets had analyzed the double rook sacrifice a couple of months ago. There are several ways to a draw in these lines, and some of them have been played before, so the players really focused on finding the right moves to a perpetual. Tiviakov and Leko played exactly as all the bookmakers had predicted, without any excitement to a quick draw.

The game of the round was clearly Nakamura’s win over Shirov. It has to be admitted that Shirov played below his standard level, but this was also certainly caused by the fact that Nakamura managed to face him with an unusual opening line, where both players had to think on their own without relying on some big preparation.

13.Ncd5 Bh6

Not the right plan.

[13...f5!? was a lot more interesting and also more in the style of the real Shirov! 14.c3 f4 15.cxd4 fxe3 16.fxe3 (16.Nxe3 Qa5+ 17.Qd2 Qxd2+ 18.Kxd2 exd4 19.Nd5 Bh6+ 20.f4 0-0 and black has nothing to complain about) 16...Qa5+ 17.Nc3 Bh6 with clear compensation for the pawn]

and now Shirov started to realize that normal continuations would not give him the desired position

[28.a3 with the idea of c4 was probably better, it will be easier for white to breakthrough on the queenside]

28...a5 29.b5 Rd8

Here Nakamura had a long think, he's clearly better because his king is much safer and his pieces are more active, but it's only a matter of 2 moves before black will be ok, so white needs to act quickly

Vladimir Kramnik was most probably lost against Nigel Short in Round 7. Photo © Michiel Abeln.

Nigel Short innovated against Vladimir Kramnik's Petroff Defence. Short won a pawn a nurtured his advantage to a winning position. Short then admitted that he became somewhat indecisive. The win was probably to be had by directly shoving the a-pawn at some stage. After Kramnik reduced the pawns down to one side of the board in a Queen and Pawn ending which is probably more drawn than won. He eventually held by a precise Queen sacrifice for stalemate.
