Tsagaan tries something different from her earlier game against Zatonskih 11... c6 12. Qc2 h5 13. Rad1 Qe7 14. Rfe1 h4 15. g4 Ne5 16. Qe2 c5 17. Nc2 Be6 18. Na3 Nfxg4 19. hxg4 h3 20. Bxh3 Qh4 21.

12. a4

Baginskaite has also seen this position in a prior game, albeit nearly 20 years ago 12. Qc2 c5 13. Nde2 b5 14. Rad1 b4 15. Nd5 Nxd5 16. Rxd5 Qe7 17. Rfd1 Rb6 18. R5d2 Bb7 19. Nf4 Nf6 20. f3 g5 21.

12... Nc5 13. Qc2 a5 14. Rad1 Nfd7 15. Ndb5 Na6

A normal idea in this position to transfer the knight into the b4 square that is now available since white played an earlier a4.

16. Rfe1 Ne5

16... Nb4 17. Qe2 b6 18. Nd5 Nxd5 19. exd5 Ba6 20. Nd4 Bb7 is ok for black.

17. Nd5

17. c5!? Nc4 18. Bf4 Nxc5 19. Nd5 Nxb2 20. Ndxc7 Nxd1 21. Rxd1 Bd7 22. Bxd6! (22. Nxe8? Bxb5) 22... b6 23. Nxe8 Qxe8 24. Bxb8

17... Be6

17... c6 is of course the biggest test of Baginskaite's 17th move 18. Bb6 Qd7 19. f4 an idea suggested by Ben Finegold during the commentary although his evaluation of the position was "messy"(19. Ba7 cxd5 20. Bxb8 Nxb8 21. exd5 is maybe slightly better for white.) 19... cxb5 20. fxe5 bxc4 21. exd6 Qxd6 22. Qf2

Baginskaite is the one to vary today after her encounter with Zenyuk yesterday.

26... Nh5 27. Kh2 Bxb2 28. Nb5 Na6

28... Rc8 29. g4 Ng7 30. Re2 Bf6 31. g5 Be7 32. Bf3

29. g4 c6?

29... Ng7 was the only reasonable defense but even here white has compensation for the sacrificed pawn.
