7. Be3 Ne4 8. Bd4 Nexc5 9. Bxg7 Kxg7 10. Qd4+. For 10. Nc3 Ne6 11. e4 d6

10. ... Kg8 11. Nc3 d6
12. Rfd1 Bd7 13. e4 Bc6 14. a3 Rc8 15. Qe3 Qb6 16. Nd5 Bxd5
17. exd5 Qxb2 18. Qxe7. Antoaneta has been too hasty in regaining her Pawn. She ought to play 18. Nd4 (Δ Rd1-b1) first, and only after 18. ... Qb6 will the White Queen take the e7-Pawn.
18. ... Rfe8 19. Qxd6 Ne4. The position is now reversed, and Black will obtain a lasting initiative for the Pawn.
20. Qd7 Nac5 21. Qg4. “Something has gone wrong with the former Women’s World Champion’s opening and Stefanova now finds herself on the defensive. Probably she was now anticipating Black capturing the c-Pawn and after 22. Rd1-f1 try to get some counterplay based on her passed Pawn”,
Grandmaster Kevin Spraggett said.
21. ... Nxf2! An intuitive sacrifice which forces the enemy King out into the open.
22. Kxf2 Ne4+ 23. Kg1 Rxc2 24. Qh3. 24. Bh1 is refuted by 24. ... Nf2! 25. Rdb1 (what else?) 25. ... Re1+!, e.g. 26. Rxe1 Nh3+! 27. Qxh3 Qb6+ and mate in three moves, while after 24. Bf1 is quite convincing 24. ... Qc3 (Δ ... Qc3-e3+) 25. Qf4 g5! (Spraggett’s analysis).
24. ... Qb6+ 25. Nd4. Obviously, 25. Rd4? Ng5! loses on the spot.
25. ... Rd2
26. Rxd2 Nxd2 27. Qg4 Re4!! Possibly the most difficult move in the game! “Black cleverly uses multiple tactical themes to created threats and make progress. If now 28. Bxe4 there would follow the forcing 28. ... Qxd4+ 29.Kg2 Qxa1 (threatening mate on f1) 30. Bd3!? Qe5 31. Qc8+ Kg7 32. Qxb7 Qd4! 33. Be2 Ne4! and the Queen and Knight duo are unstoppable”,
Spraggett said.
28. Qc8+ Kg7 29. Qc3 Rxd4. “And now the simplest winning plan is to simplify with 29. ... Qxd4+ 30. Qxd4 Rxd4 31. Rd1 Kf6! when the ending offers no hope. (In the game Kashlinksaya played the less accurate 29. ... Rxd4, but won anyway in 64 moves”,
Spraggett said.
30. Rd1
Kf8 31. Qc8+ Kg7 32. Qc3 f6 33. Kh1 Ne4 34. Qxd4 Nf2+ 35. Qxf2? The only chance was to defend the endgame a Pawn behind: 35. Kg1 Nxd1 36. Qxb6 axb6.
35. ... Qxf2 36. d6 Qe2 37. Ra1 Qd2 38. Bf3 Qxd6 39. Bxb7 Qb6 40. Bg2
Qb2 41. Rd1 Qxa3. Black’s preponderance of Pawns is decisive. The rest is a matter of technique, as they say.
