There were just two decisive games, both wins for black from 8 games in the quarter finals of the FIDE World Cup. Peter Svidler managed to beat Alexei Shirov in the tie of the round. Shakhriyar Mamedyarov is making quiet progress through the tournament.
Alexei Shirov's attack against Peter Svidler was repulsed calmly by the Russian who went on to win in 36 moves.

A novelty, this move doesn't open the f-file and so may not be such an improvement.

Really going for it. White's attack looks really scarey but in the end with best play it probably works out better for black.

Alexei Shirov
Position after 25.Qh4
25...Kg7!
[25...Qxf2+ 26.Kh2 h5 27.Qg5 May have been what Shirov expected.]
26.Re3 Rd6 27.Rf3 h6
Black has correctly caculated his way through the complications. Now white is in trouble.
28.Ne4
[28.Rf1 Ne5 29.Re3 Rxf6 30.Rxe5 Qc5 is winning for black.]
28...Rxd5 29.Qf6+ Kg8 30.Rc3
[30.Rf1 would be miserable but perhaps is necessary.]
30...Ne5 31.Rf4 Qxa2 32.Kh2 Qe2
[32...Ra6]
33.Qh4 Ra6 34.g4
It's been over for some time but now black just wins huge chunks of material.
34...g5 35.Nxg5 hxg5 36.Qxg5+ Rg6 0-1
Shakhriyar Mamedyarov has made extremely smooth progress so far. Today was no exception. Viktor Laznicka got a position where it wasn't really apparent what his plan should be. Gradually Mamedyarov put on the pressure and broke through just before first time control.

From here abouts white seems content with a draw and starts to play somewhat aimlessly. Pretty soon his position starts to get difficult.

Shakhriyar Mamedyarov
Position after 36...Ra3
37.Rf1?
Now white probably has to allow a very scarely looking attack because this just seems to lose.
[37.Qb2 Bxh3 38.gxh3 Qxh3 39.Nd1 Qg3+ 40.Kf1 h3 41.Qf2 Bxf4 42.Qxg3 Bxg3 43.Nf2 Rb3 44.Rc1 h2 45.Kg2 Bd6 46.Ng4 Rxb5 47.Rc2 Rb1 48.Nxh2 b5]
37...Rb3 38.Ra1 Ba3 39.Ra2 Bb1 40.Nxb1
This definitely loses other options aren't that appetising either.
[40.Rxa3 Rxa3 41.Nxb1 (41.Nb4 Be4) 41...Ra1 42.Qe1 Qe4]
40...Rxb1+ 41.Kh2 Bc1 42.Qe1 Qe4 43.Ra7 Qxf4+!!
Not too tough to calculate but pretty none the less.
44.Kh1 Qf2
[44...Qe4 is even better]]
45.Rxc7+?
[45.Qxf2 Bxe3+ 46.Qg1 Rxg1+ 47.Kh2 Kh6 48.Ra2 Rd1 49.g3 hxg3+]
45...Kh6 46.Qd1
[46.Qxf2 Bxe3+ 47.Kh2 Bxf2 48.g4 Bg3+ 49.Kg2 Bxc7 is also winning.]
46...Qe2 47.Qg1 Qxe3 48.Qf1 Qf4 49.Qd3 Ra1 0-1
Maxime Vachier-Lagrave and Boris Gelfand drew quite an interesting Petroff Defence. I'm sure the final position is drawish but I would have liked to see a few more moves to see how it should play out.
