Qd8+ Rg8 ½ : ½ Inarkiev – Fedoseev, 35th European Chess Club Cup, Ulcinj 2019) 13. ... Bxf5 14. Be3 0-0. The alternative is 14. ... Rc8 15. Qa4+ Qd7 16. Qxd7+ Bxd7 17. Ne4 Bf8 18. f4 f5 19. Nf6+ Ke7 20. fxe5 dxe5 21. Nxd7 Kxd7 22. Rac1 Bg7? (⌓ 22. ... Bc5! 23. Bxc5 Rxc5 24. b4 Rc7 25. c5 b6!) 23. b4 f4 24. Bb6 Rhf8 25. c5 e4 26. c6+ bxc6 27. dxc6+ Ke6 28.

Rxe5+ Kxe5 37. b5 Kd5 1 : 0 Maghsoodloo – Fawzy, 4th Sharjah Masters International Chess Championship, Sharjah 2021. 15. Qb3!? A sharp novelty by Shirov. Non-relational database theory says 15. Rc1 Rc8 16. Qe2 Qh4 17. b3 Bd7 18. g3 Qh3 19. Ne4 f5 20. Ng5 Qg4?? (⌓ 20. ... Qh6 Δ 21. Ne6 f4∞) 21. Qxg4 fxg4 22. Ne4+− H. Franco – R. S. Freitas, 13th Campeonato Brasileiro Aberto, Jundiai 1998.


15. ... Bd3 16. Rfc1 e4 17. c5 f5 18. cxd6 f4!? 18. ... b5 was a sound continuation, but Fedoseev aims at a more rewarding goal. 19. Bb6


19. ... Qg5? Consistently Black plays heavily on his possibility of a mating attack, which however turns out to be a chimera. A plausible continuation might be 19. ... Qxd6! 20. Bc7! Qxc7 21. Nxe4 Qxc1+ 22. Rxc1 Bxe4 23. Rc7 b5 with an unbalanced equilibrium, but an easier play for Black. 20. d7! f3 21. d6+! Clearing the d5-square for the Knight. 21. ... Kh8 22. g3 Qf5 23. Nd5 Qh3 24. Ne3. So Back’s attack came to a dead end. 24. ... Qxd7. Restoring material equality, but only temporarily, because now it is White who can afford to give up a Pawn for the sake of a direct attack on the King.


25. Rc7! Qxd6 26. Rac1. Threatening 27. Rxg7! Kxg7 28. Rc7+ Kh8 (28. ... Kh6 29. Ng4!+−) 29. Qc3!+− with mate in a few moves. 26. ... Rg8


27. Ba5! Heading for the a1-h8 diagonal. 27. ... Bb5 28. Rxb7 Rac8? That is to prevent Rc1-c7, but it costs Black as much if not more. On the other hand 28. ... Qd3 is only apparently more resilient, for after 29. Bc3! Bxc3 30. bxc3 Black would be also helpless. 29. Rxc8 Rxc8 30. Bc3! 1 : 0.

Summing up one could say that Shirov was in his best attacking style. Photo: Mark Livshitz/Fédération Internationale des Échecs (FIDE).
