1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. c1e3  6... e7e5  7. d4f3 The Najdorf is a great opening for Black, and White surely has no advantage anywhere. But, the burden of memorization is extremely high, and there are a ton of lines you need to know. As such, most people jump around a lot with the white pieces and look to poke and prod in different spots. I would know firsthand—I actually beat the Najdorf twice myself in the recently concluded Prague Masters, but I chose a different line the second time around. It surprises me a little that Hikaru repeated the same variation that he played with Firouzja a few days ago, but you can't argue with success $1 7... f8e7 The main move. 8. h2h3 This has been something of a trend as of late, though it doesn't strike me as that challenging for Black. 8... h7h6  9. f1c4  9... c8e6  10. c4b3 This position is extremely common without h3 and /h6 included, and I don't think their inclusion should change much. 10... b8c6 Probably fine, but might not be totally necessary. 11. f3h4  11... c6a5  12. b3e6  12... f7e6  13. h4g6 Once the knight gets to g6, White should be able to put some pressure. Still, it's nothing too amazing since Black's king will be fine on f7. 13... h8g8  14. e1g1  14... a5c4  15. e3c1  15... a8c8  16. h3h4 I think this was a misunderstanding of the position. White's knight on g6 is not really worth maintaining—it did its job by preventing castling. Its highest and best use will be to take e7 once it is attacked. 16... c8c6  17. d1f3  17... e8f7  18. h4h5  18... d8c7  19. c3d1  19... c4b6  20. d1e3  20... b6d7  21. c2c4 The last several moves have been fine enough, but again, I think Hikaru made the wrong choice when the g6-knight was attacked. 21... d7f8  22. g6h4  22... f8h7 Now all of a sudden White is more or less losing a pawn by force. /Ng5 is coming and White cannot move the knight on e3 without losing c4. Still, he retains compensation since Black's position is a bit loose, his structure is not great, and White has more space. 23. b2b3  23... h7g5  24. f3e2  24... g5e4  25. c1b2 It's not that hard to imagine an f2-f4 advance coming and causing trouble in the coming moves, but Black should be a bit better if he plays it right. Duda played it well to a point. 25... g8e8  26. h4g6  26... f7g8 Castling by hand is a good start. 27. a1d1  27... a6a5  28. e3g4
