Be2 Na4 14. cxd5 exd5 15. c4 Rc8 16. Qb3. Grandmaster Arkadij Naiditsch calls it “A serious mistake in a complicated position. And it was such a chance for Anna to come back into the match! The right move was 16. Rac1! with the idea of playing 16. ... Nac3 17. cxd5 and of course things are very complicated here, but my feeling says White should somehow be better”. 16. ... dxc4!? A novelty as well as an improvement on 16. ... Nac3 (Gundavaa – Alekseev, 2nd Universiade, Kazan 2013). 17. Bxc4? “A blunder. Perhaps, already 16. Qb3 wasn’t the strongest choice. White should have taken on b7: 17. Qxb7 Nac5 18. Qb2 with approximately equal play”, Evgeny Anatolyevich Surov wrote. 17. ... Nac3 18. a4? “The only possible way to keep up fight was 18. Bxf7+!

18. ... Bxa4! 19. Rxa4 Nxa4 20. Nf5. Or 20. Qxa4 Nc3! 21. Qb4 (21. Qxa7 Rxc4) 21. ... Qxd4 22. Bxf7+ Rxf7 23. Qxd4 Ne2+ and wins. 20. ... Nac3 21. e6 Rxc4 22. Qxc4. If 22. e7 then 22. ... Qd3! 23. exf8+ Kxf8 24. Qa3+ Rc5! 25. Bd6+ Kg8! 26. Bxc5 Ne2+ 27. Kh1 Nxf2+!! and finis. 22. ... b5 23. Qb3 Qd3 24. exf7+ Rxf7 0 : 1.
