context: 1. d2d4  1... d7d5  2. c2c4  2... c7c6  3. g1f3  3... g8f6  4. b1c3  4... e7e6  5. c1g5  5... b8d7 The safest option for Black, taking the game to the Orthodox Defense. 6. e2e3  6... d8a5 The Cambridge Springs Variation has a vast legacy and was employed in the magnificent 1927 match between Capablanca and Alekhine. 7. c4d5  7... f6d5  8. d1d2  8... f8b4  9. a1c1  9... h7h6  10. g5h4  10... e8g8 10...b6 and 10...c5 are important alternatives. 11. a2a3  11... b4c3  12. b2c3  12... d5f6 A rare move. The players with Black usually accept the pawn sacrifice. 13. f1d3  13... b7b6 This move has never been played before, according to my database. Black wants to continue the thematic development of the bishop on a6. 14. e3e4  14... c8a6  15. c3c4 It's important to avoid the exchange since the pair of bishops is precisely one of the reasons for White's advantage. 15... a5d2  16. e1d2 With the bishop pair and a powerful pawn center, there's no doubt about White's advantage, but perhaps it's not as big as it seems. In any case, Fedoseev is an almost unparalleled master at turning questionable positions into victories. 16... f8e8 Preparing the break on e5. 17. e4e5 A natural reply, advancing the center and preventing it from being broken with e6-e5. The computer is not a big fan of this move. 17... f6h5 They say that a knight on the rim is dim, but what happens when we have to choose between two squares in the corner of the board $2 A saying definitely needs to be written about this too in order to help our decision-making. 18. d3e4  18... a8c8  19. g2g4  19... h5f4  20. h4g3  20... f4g6  21. h1e1 With accurate play, Firouzja manages to keep his center intact. 21... c6c5 Too hasty. Black has no adequate response against the d-pawn advance. 22. d4d5 Forced and excellent. 22... e6d5  23. c4d5  23... c8d8  24. d2c3 A good move, taking the king out of the x-ray with the black rook. 24... a6b7  25. a3a4 I'm a big fan of calm, prophylactic moves in advantageous positions. Firouzja prevents the b6-b5 move, which can give Black counterplay. 25... d7f8  26. c1d1 The center is pretty safe. 26... g6e7  27. d5d6  27... b7e4  28. e1e4  28... e7c6  29. f3h4 The knight prepares to go to f5 and also gives space for the pawn to advance to f4. 29... f7f6  30. f2f4  30... f6e5  31. f4e5  31... e8e6  32. c3c4 The king approaches fearlessly and helps to break the blockade. 32... d8e8  33. h4f5  33... f8d7  34. d1e1  34... a7a6  35. c4d5  35... c6b4  36. e4b4  36... c5b4  37. f5d4 With the exchange sac, White forces the rook to retreat, and the pawns advance under the supervision of a formidable army. The two little warriors will eventually meet their fate, but they will take with them pieces of greater value on their heroic journeys. 37... e6g6  38. e5e6  38... d7f6  39. d5c6  39... g6g4  40. d6d7 I suspect that something like a \"perfect game\" is impossible at such a fast time control, but this one was close. Unfortunately, something of its beauty is lost with this serious mistake. 40... e8d8 A mistake in reply. For those with a fatalistic mindset, perhaps this mistake will do justice and not ruin the deserved result of the game. 41. g3e5 The game gets back on track. Black has no chance. 41... f6d7  42. e6d7  42... b4b3
