24. ... Rc4! “Black’s threat is 25. ... Rc8 and if 26. Na6 Bxf3+ winning thanks to his tripled heavy pieces on the c-file”, writes Europe Échecs’s editor-in-chief Grandmaster Bachar Kouatly. 25. Na6? Svidler completely loses the thread of his embroidery. Correct was 25. a6 Rc8 26. a7 Rxc7 27. Rxc4 Qxc4 28. a8=Q+ Bxa8 29. Rxa8+ Rc8 with equality. 25. ... Qf2! Threatening ... Bc6xf3+. 26.
