Then infiltrates with his rook.
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. f2f3  4... d7d5  5. a2a3  5... b4e7  6. e2e4  6... d5e4  7. f3e4  7... c7c5  8. e4e5  8... f6d7  9. d4c5  9... d7e5  10. d1d8  10... e7d8  11. f1e2 All of this has been  played recently as well. After some thought Anand uncorked a novelty. 11... c8d7  12. g1f3 Firouzja is taking his time as well and reacts in a logical way. 12... e5f3  13. e2f3  13... d7c6 The white bishop cannot be tolerated. 14. c3e4 Heading to the d6 square. 14... d8c7 Anand comfortably regroups his forces. But since the  bishop can no longer hurt White on the long diagonal now... 15. b2b4  ...becomes possible. 15... b8d7  16. c1b2  16... d7e5  17. e1c1 Only this is inaccurate. 17... e5f3  18. g2f3  18... c7f4 An important difference in comparison to the  line from above. The bishop will be active. 19. c1b1  19... f7f6  20. h1g1 White's  initiative fizzled out. From here on it will be only Black to improve his  position, hence White's next decision to trade the enemy bishop pair. 20... e8f7  21. e4d6  21... f4d6  22. d1d6  22... g7g5 With the threat of Bxf3. 23. g1f1  23... a7a6  24. b1c2 Firouzja does not feel the danger! This  opposite-colored bishop endgame with rooks is far more insidious than it  seems. 24... h8d8  25. c2d2  25... e6e5 Now the f3 pawn is fixed and although it will  take Black 20 moves to take it, it never stood a chance. 26. d2e3  26... d8d6  27. c5d6  27... f7e6  28. c4c5  28... b7b6 Black's pieces are doing great; now he needs the  rook out. 29. h2h4  29... h7h6  30. h4g5  30... h6g5  31. c5b6  31... a8b8  32. f1d1  32... b8b6  33. e3f2 With the idea to maneuver the bishop all the way up to c5. 33... c6a4 Which is easily spoiled by the Indian  GM. 34. d1d2  34... b6b8  35. f2g3  35... b8c8  36. g3f2  36... c8c4 The rook is out, but Anand is not in  a hurry. He first makes it to the time control. 37. f2g3  37... c4c8  38. g3f2  38... c8h8  39. f2g3
