Kb1 Qd5 with a volatile, dynamic, and complex balance, Shimanov – Dubov, April 5 Titled Tuesday Early, chess.com, April 5, 2022 (time control: 3 minutes plus 1 second per move). 10. Be2 Bd7 11. a4 Qb6 12. 0-0 c4?! Strategically speaking, a committal decision. 13. b3 cxb3 14. cxb3 Rfc8 15. a5 Qd8 16. b4 Qe8 17. Nc3 e6 18. b5 Nc7 19. Rab1 Qe7


20. b6. Perhaps a bit too hasty. White could quietly play 20. Rfc1 and if 20. ... Ne8 then 21. e4! with the much better game. 20. ... axb6 21. Rxb6. And not 21. axb6? by reason of 21. ... Ne8 heading for d6. 21. ... Bc6 (21. ... Rxa5 22. Rxb7 Bc6 23. Rb6 Ne8 24. Rfb1⩲) 22. Na2


22. ... Ra7? The right move was 22. ... Qa3! so as to reply to 23. Bxc7 with 23. ... Qxa5! somehow holding on (24. Qxa5 Rxa5 25. Rxc6 Rxa2=). 25. 23. Rc1. 23. Nb4! at once seems to be much stronger. 23. ... Rca8? Black was still in time for 23. ... Qa3, though now, after 24. Bxc7 Rxc7 25. a6 White retains the better chances. 24. Nb4! Finally! 24. ... Ne8 (24. ... Rxa5 25. Rbxc6!+−)


25. a6! Qd8 26. Rbxc6! bxc6 27. Nxc6 Qd7 28. Nxa7 Rxa7 29. Bb8 Ra8 30. a7 Bf8 31. Qa5 Bd6 32. Bb5 Qe7 33. Rc8! 1 : 0.
