It has never been played by a titled player. The bishop starts looking at the kingside and White needs to take some defensive care. Black is preparing Qe7-Rad8 and in some lines Qe5, threatening mate. 14. c1e3  14... f8e8  15. f1e1  15... e8e3 A thematic exchange sac to attack using the dark squares. Of course Firouzja spices the game up at the first opportunity. 16. f2e3  16... d8e7  17. d1d4 A good move, centralizing the queen and preventing Qe5. It looks scary since Black can play 17...Bc5 and capture on e3, but this is not such a big danger. 17... a8d8  18. e2f4  18... d6c5  19. d4c3  19... c5b4  20. c3c2  20... b4e1  21. a1e1 Black managed to get the exchange back and the position is equal. 21... e7e5 A small inaccuracy that makes Black's position harder to play. 22. c2b3 A strong move, putting pressure on the pawn on f7. 22... h5g6 Sacrifing the pawn, but I'm not sure this was necessary. 23. f4g6  23... h7g6  24. c4f7  24... g8h7 Black has good compensation because his pieces are active and queen and knight always combine well. 25. b3c3 The best move to fight for an advantage, 25... e5g3  26. e1f1  26... f6d5  27. f7d5 There's nothing more human than capturing this knight, but it's not the best move. 27... d8d5  28. g1h1  28... c7c5  29. b2b3  29... g3d6 Control of the d-file and activity ensure equality for Black even a pawn down. 30. e3e4  30... d5d2  31. a2a4
