Bonin, J. (2310) - Vayserberg, T. (2023) [A80]
1. d4 f5 2. Nc3
2...Nf6 This 2.Nc3 line and others you can see in my work "Dutch A80-A85" (ChessBase). 3. Bg5 d5 4. Bxf6 exf6 5. e3 Be6 6. Bd3 Nc6 7. Qf3 Qd7 8. a3 O-O-O 9. Nge2 g6 10. Nf4 Bf7 11. Bb5
11...Qd6 Black made a draw after 11...Kb8 12. Nd3 Qd6 13. O-O Ne7 14. Nc5 Nc8 15. b4 c6 16. Bd3 Qc7 17. Rab1 Ka8 18. Ne2 Nd6 19. Nf4 1/2, Mirzoev, A - Herraiz Hidalgo, H, Elgoibar 2004. Better is 16. Be2! Qc7 17. Rfb1 with initiative on the queenside. 12. O-O Ne7 13. b4 h5 14. Nd3 g5 15. Nc5 g4 16. Qe2 f4 17. exf4 Nf5
18. Rfd1 A reasonable alternative is 18. Bd3!? Nxd4?! (18...Ng7 19. Qd2 or 18...Nh4 19. Qe3) 19. Qe3 Nc6 20. Nb5 Qe7 21. Bf5+ Kb8 22. Qxe7 Nxe7, and White wins the exchange with 23. Nd7+ Rxd7 24. Bxd7. 18...Nh4 19. N3a4 19. Re1 is not bad. 19...Bh6 20. Rab1 Bxf4
21. Ba6!! An excellent blow! 21...bxa6 22. b5!!
22...Rde8 Here if 22...Rhe8 then 23. b6 Rxe2 24. bxa7 with quick mate. White develops a powerful attack after 22...Rd7 23. b6! cxb6 24. Nxb6+ axb6 25. Qxa6+ Kc7 26. Nxd7. The most earnest response is 22...Nf3+!? 23. Kh1 Rde8. Now the typical 24. b6? leads to a crushing defeat 24...Rxe2 25. bxa7 Kd8 26. a8=Q+ Ke7 27. Qxh8 Be3! and Black checkmates. So the first player must continue 24. Qd3! Be3 (24...Nxd4 25. b6 Nb5 26. Rxb5 axb5 27. bxa7 Qc6 28. Qxb5 Qxb5 29. a8=Q+ Qb8 30. Qa6+ Kd8 31. Qxf6+ or 24...Bg5 25. gxf3 Qf4 26. b6) 25. gxf3 Qf4 26. fxe3 Rxe3 27. b6! axb6 28. Qxa6+ Kd8 29. Nxb6 Ke7 30. Rf1 gxf3 31. Nd3, winning.
23. b6!! An amazing queen sacrifice. 23...Rxe2 24. bxa7 Bxh2+ 25. Kh1
25...Kd8 White threats Rb8. 26. a8=Q+ Ke7 27. Qxh8 Nf5 28. Rb8 Black resigned. 1-0 Top
