A good prophylactic move.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4 Praggnanandhaa is a great specialist in the Italian Opening, with excellent wins with both colors. 3... f8c5  4. d2d3  4... g8f6  5. e1g1  5... d7d6  6. c2c3  6... a7a6  7. f1e1  7... c5a7  8. b1d2  8... e8g8  9. d2f1  9... c6a5  10. c4b3  10... a5b3  11. a2b3 This opening is a little shocking. When I was a kid, my trainers told me never to let a knight capture my light-squared bishop in the Italian or in the Spanish. Time passes and new ideas appear, but is the old wisdom wrong $2 The position doesn't seem too scary for Black, although White's side has already been defended by several elite GMs, including the legendary Vishy Anand. 11... h7h6 Always a useful move, preventing the pin with Bg5. 12. f1g3  12... f8e8  13. h2h3 To be quite honest, I don't really know what White has in exchange for the very powerful light-squared bishop. For now, he is heading toward the traditional plans, playing Be3 or maybe Nh2-Qf3-Ng4 and trying an attack on the kingside. 13... b7b5 Black expands the queenside and prepares the development of the bishop on b7, a good diagonal, despite leaving the f5-square weakened. To protect the king, Black relies on the traditional rook move to e6, reinforcing the defense through the sixth rank. 14. b3b4  14... c8b7  15. f3h2  15... d6d5 It's a natural reaction to break in the center and seek life for the bishops. 16. d1f3  16... e8e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] 17. g3f5  17... g8h7  18. f3g3  18... f6e8 A move that requires accurate calculation, something that Gukesh certainly isn't lacking. 19. h2g4  19... d5e4  20. d3e4  20... e8d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] It's scary to leave the g7-square unprotected, but in chess the best thing is not to see ghosts and believe in the calculation. 21. g4e5  21... d6f5 [%c_effect f5;square;f5;type;Mistake;persistent;true] This is a big mistake that puts Black in trouble. Black has good play with three queen moves. 22. e4f5  22... e6f6  23. c1e3  23... a7e3  24. g3e3  24... f6f5  25. a1d1  25... d8f6  26. f2f3 White has a big advantage here. His last move reduced the bishop's potential, and he is now ready to penetrate on the seventh rank. In some cases, the knight can find a very strong square on c5. The rook on f5 is misplaced and in trouble. 26... h6h5
