Nothing,  except that logic is sometimes hidden between the lines. 16... d8d5 The white queen is almost trapped! How unfortunate it can  be? 17. c2d4 Giving up a whole rook, and that is the lesser evil... 17... c6d4  18. f3d4  18... c3a1  19. f1g2  19... a1c3 Instead of a piece down, Gukesh  is an exchange and a pawn ahead. How did Duda find the strength to carry  on after this blow?! 20. h1b1 Even with reduced material Duda, finds a  way to create mating threats. 20... d5a5  21. a4d1  21... c3d3  22. d1g4 The white pieces suddenly coordinate. 22... f7f5 Gukesh avoids the perpetual check. 23. g4g7  23... d3e4  24. d4f3 The sign is for the courage to fight for the top eight. 24... h8d8  25. b1b4  25... a5c5 At last Gukesh cements his position, and nothing seems to  stop him now. 26. g7c3  26... c5c7  27. b4b5  27... a7a6
