(1) Carlsen,Magnus (2855) - Karjakin,Sergey (2773)
Bilbao Masters , 2016
[GM Lubomir Kavalek/The Huffington Post]

The protection of the black king is weakened by the missing g-pawn and Carlsen launches a kingside attack.

31.g4!? a5 32.Rg2 Nh7
[The strength of White's attack is demonstrated by this variation: 32...a4 33.g5! hxg5 34.Rxg5!! Ne8 35.Rfg1! f6 (35...axb3 36.Qg3+- ) 36.Rg6! axb3 37.Qh5 e6 38.Rh6 and White mates.]

33.h4 Rb6
Karjakin rushes his rook back to help the king. [33...a4 34.Bd1+/- ]

34.g5!
The offensive begins and Karjakin has to decide how to set-up his defense.

34...Kh8
[After 34...Rg6 35.Rfg1 the pressure is mounting, but it was the best choice.; Exchanging the g-pawns gives White the h-file for the onslaught. One possible line is 34...hxg5 35.hxg5 Rg6 36.Qh5 Qd6 37.Rfg1 Rd8 38.Rh2 Nf8 39.Rf1 threatening 40.Qf3.]

35.Rfg1 f5?
Karjakin was probably fed up with a passive defense, but his last move makes Carlsen's task easier. [35...Rg6 36.Ba4 (36.gxh6 Bxh6= ) 36...Qc8 37.Rh2 ]

36.Qh3!+-
An unpleasant pin that allows White the final attack along the g-file.

36...Rb4?
Nothing helps, for example: [36...Rd6 37.gxh6 Bxh6 38.Qg3 Nf6 39.Qxe5+- ; 36...hxg5 37.hxg5 Rg6 38.Rh2+- ]

37.gxh6! Bxh6 38.Qg3!
A nasty double-attack, threatening 39.Qg8+! and 39.Qxe5. [White also wins after 38.Rg6 Bf4 39.Qg2 Nf6 40.d6 Ng4 (40...Rxb3 41.axb3 Qxd6 42.Nd5+- ) 41.exf5+- ]

38...Nf6 39.Qg6! Ng4 40.Rxg4
[40.Rxg4 fxg4 41.Qxh6+ Kg8 42.Qg6+ Kh8 43.Qh5+ Kg7 44.Rxg4++- ] 1-0
