Also 22. ..Nxd3 seems good exchanging off the white bishop.

29..gxf5 seems better then Rxe4.

Interesting story, Peter pointed out that he was not familiar very much with this position.So this is pure improvisation from his side.

18.dxe5N

New move, old one is 18.Bg5.

18..Ng4

Of course not 18..Nxe5 19.Nxe5 wins the piece.

19.Bg5 Qc5 20.e6 ( diagram )

First critical moment and Karjakin passed the test on this one.

20..Nde5

Good move, let's just other options.20..Qxc2?? is horrible blunder 21.Bxc2 and Black two pieces are hanging.20..fxe6!? is interesting.21.Qb3 now 21..Nge5 22.Qxe6+ Rf7, computer gives equal on this one but to human eye it may look a bit risky ( 21..Nde5 22.Qxe6+ Rf7 is also possible ).Move played in game is doing very good.

21.Nxe5 Nxe5 22.Bf6 ( diagram )

Second critical moment.

22..Qxc2?

Karjakin thought for a long time on this one, "long think - wrong think" and came up with huge error.22..Nxd3! 23.Qxd3 fxe6 24.e5 Qc3! and Black is better, point is that after 25.Qd7 Rf7 26.Qe6 Bc8! ( pointed by Svidler ) is much better for Black.It's hard to explain this oversight.After 22..Qxc2 Black gets into worse but still defendeable position.

23.Bxc2 Bd6

23..Bc3? is wrong 24.e7! is giving to White advantage.

24.Bb3 fxe6 25.Bxe6+ Nf7 ( diagram )

White's Bishops are huge force, Black must neutralise them, especially that light square guy.

26.f4!

Right! With idea 27.f5 to open f-line and to expose f7 point to attack.

26..Bc8 27.Bb3 Re8 28.f5 Bxg3

Maybe 28..Ra7!?

29.hxg3 ( diagram )

29..Rxe4??

Really bad day for Karjakin :( Another huge mistake.29..gxf5! 30.exf5 c5 in only try, Black must close those Bishops.If 31.Bd5 Ra6 seems to hold, like 32.Bb2 Rd6, if 31.Rf4 Kf8! with c4 next to holding.Notice that here 31..c4? right away is mistake because of 32.Rg4+! ( check! )

30.Ra1

Now is difficult to advise Black, Rook will penetrate to seventh rank, Bishops are still alive...

30..Rxa1 31.Rxa1 Kf8 32.Ra7 Ne5 33.Rxh7 Nc4?

This is speeding up the end, more stubborn 33..Re1+ is also worthless.

34.fxg6

At this point White can choose how to win.

34..Be6 35.Bc2 Re2 36.Bd3 Re3 37.Bf5 Bd5 38.Kf2 Re8 39.Bd7 Nd6 40.Bg7+ 1-0

A nice game by Svidler. I really like the idea of 28 f5 and 31 Rxa1. A game of mistakes by Karjakin, but take nothing away from Svidler who saw some nice idea’s.

Svidler really deserves a win. He seems to have come to this tournament with great enterprise and adventure. He played a rare Kings Indian in his first game, played a rare line against Carlsen in his second game, and admitted that he didn’t play the best opening moves against Gashimov because (in his own words) he said he decided it was time for adventure! He sportingly helped analyze his loss to Gashimov, and was rewarded an audience with the Azerbaijan prime minister in analyzing the game with Radjabov. Svidler seems to be enjoying this tournament! Svidlers been born again. A great talent. A big threat if he keeps up his energetic mood.

Maybe that's an android replica and not the real Peter Svidler...
