1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 0-0 5.Nge2 d5 6.a3 Be7 7.cxd5 exd5 8.b4 c6 9.Ng3 Re8 10.Bd3 Nbd7 11.0-0 Nb6 12.Rb1
Both Kosinsteva sisters have played this line with Black, with Tatiana's latest foray dating from last year, when she followed Kramnik's choice of 12...a6 from Navara-Kramnik (2008). Kramnik's plan is not for everyone though, and if you suffer from claustrophobia, another approach is recommended.

12...Bd6 13.Qc2 Be6 14.a4 a6 15.a5 Nc8 16.Na4 Na7 17.Nc5 Qc7 18.f3 Nb5
Kramnik played this knight maneuver too, though via d6 instead of a7. In this game, though the knight looks well-placed, it is shown to be biting on dust.

19.Qf2 h5 20.Re1 Rad8 21.Bb2 Bc8 22.Rbd1
Socko is rerouting her pieces to prepare for the thematic e4 push. Kosinsteva really cannot do anything to prevent it, and is reduced to getting ready to fight against it and hope for the best.

22...Re7 23.Nf1 Ree8 24.h3 Nd7 25.e4 dxe4 26.fxe4 Nf8 27.Qf3 Ng6 28.e5 Bxc5 29.dxc5 h4 30.Bxg6 fxg6 31.Qe4 g5 32.Qg6 Qe7 33.e6!
the bishop on b2 is upgraded from e5 supporter to intercontinental ballistic missile.

33...Nc7 34.Rxd8 Rxd8 35.Ne3 Bxe6 36.Ng4 Rf8
Houston, we have a problem.

37.Nh6+ Kh8 38.Nf5 Rxf5 39.Qxf5 Kg8 40.Qe5 Kh7 41.Qd6 Qf7 42.Rf1 Bf5 43.Qe5 Kg6 44.Rxf5 Qxf5 45.Qxg7+ Kh5 46.Qxc7
The bishop on b2 may look like it is hanging...

no, it isn't a blunder. [the bishop is untouchable, since 46...Qb1+ 47.Kh2 Qxb2 runs into 48.Qh7# ]

47.Qe5 1-0
