Moving the pawn only one square forward is a fresh idea that quickly takes the game out of well-known paths. 11... e4c5 Narayanan took more than 10 minutes to play this, indicating he was surprised by Gukesh's previous move. 12. b3c2  12... e6g4  13. h2h3 Gukesh was probably out of book as well, since he thought for nearly 20 minutes before playing this. 13... g4h5  14. b1d2 This position has never occurred before in a grandmaster game. 14... f8e8  15. d2b3  15... e7f8 A new move. 16. g2g4 Necessary since the e5-pawn is attacked. 16... h5g6  17. b3c5  17... f8c5  18. b2b4 This move is typical of the Ruy Lopez, preparing Bb3 or a4 next, but it's not the best here. 18... c5b6 A good move, although there are options. 19. c1f4  19... d8d7 [%c_effect d7;square;d7;type;Inaccuracy;persistent;true] The beginning of Black's problems. 20. c2b3  20... c6e7  21. a2a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true] Now White finally has the typical Spanish pressure. 21... c7c5  22. b4c5  22... b6c5  23. f3d4 A natural move, but the machine indicates two alternatives that are more promising. 23... b5b4 [%c_effect b4;square;b4;type;Inaccuracy;persistent;true] 24. c3b4  24... c5b4  25. a1c1 The knight is very strong on d4; White has a better pawn structure, more active pieces, and all sorts of tactical possibilities. 25... b4a5 [%c_effect a5;square;a5;type;Inaccuracy;persistent;true] 26. d4c6 [%c_effect c6;square;c6;type;Inaccuracy;persistent;true] This looks like a deadly blow, and I was really impressed by it. The computer, unfortunately, sometimes takes away our illusions. 26... e7c6  27. b3d5 In order to survive, Black has to find a series of incredible moves from now on. 27... c6b4 [%c_effect b4;square;b4;type;Mistake;persistent;true] 28. d5a8 White is an exchange up for no compensation. 28... d7a4
