1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. b1c3  3... f8g7  4. e2e4  4... d7d6 \"He is a very solid player, so the King's Indian was a normal choice I think.\" (Firouzja) 5. f1e2  5... e8g8  6. h2h4 \"Very fresh [approach].\" (Firouzja) 6... b8c6  7. d4d5  7... c6e5  8. h4h5  8... c7c6  9. h5h6  9... g7h8  10. g1f3  10... e5g4 A novelty. Black keeps all the pieces and pawns on board, making it as complex as it can be. 11. e1g1  11... d8b6  12. d1b3 A very solid aproach by Deac. 12... f6h5  13. f3h2  13... h5f6  14. h2f3  14... f6d7 A sign of courage $1 Black knows that he is worse, but shows fighting spirit. 15. b3c2  15... d7c5  16. c1f4  16... a7a5  17. a1e1  17... f7f5 \"I am not very sure about this move. It is very risky, but probably I should play it.\" (Firouzja) 18. e4f5  18... f8f5 Bringing more energy into the battlefield. 19. f4g5  19... b6d8  20. c2d2  20... d8f8  21. e2d1 But Deac skilfully maneuvers. Once that this bishop gets a working diagonal, White can claim an advantage. However, the problem for the Romanian GM was that he was fast approaching time-trouble. 21... f5f7  22. b2b3 Loosening the position of the knight and Firouzja needs no second invitation. 22... g4h6 A pawn is a pawn. 23. d5c6  23... b7c6  24. f3d4 \"A blunder.\" (Firouzja) 24... h6f5  25. d4c6  25... c8b7  26. d1f3 This only makes things worse for the knight. 26... a8a6  27. c6e7 The best chance $1 27... f5e7  28. f3b7  28... h8c3  29. d2c3 \"I was winning, a piece up, but it was never easy as the king was always open.\" (Firouzja) 29... c5b7  30. e1e2  30... h7h6  31. g5c1 Occupying the long diagonal. Now Black will always need to appoint someone to protect his king. 31... a6a8  32. c1b2  32... g8h7  33. f1e1  33... b7c5  34. c3d2  34... e7f5  35. d2d5  35... h6h5  36. b2c3  36... c5d7  37. e2e6  37... a8c8  38. c3a5  38... d7f6 This natural move throws the win away. 39. d5d2  39... c8e8  40. a5c3  40... e8e6  41. e1e6  41... f6d7
