Bressanone (布雷萨诺内)

Markku Henttinen – Enrico Paoli
IV International Open, Bressanone, October 1978
Queen’s Gambit Declined D47

1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. e3 Nbd7 6. Bd3 dxc4 7. Bxc4 b5 8. Bd3 b4 9. Ne4 Bb7 10. 0-0 Be7 11. Qc2?! For the immediate 11. Nxf6+ Nxf6 12. Qe2 see Tarjan – Paoli, Odessa 1976). 11. ... Rc8 12. Nxf6+. Another try is 12. Rd1 c5 13. Nxf6+ Bxf6 14. dxc5 Qa5 15. c6 Bxc6 16. Be4 b3 17. Qd2 Qxd2 18. Nxd2 Nc5 19. Bxc6+ Rxc6 20. Nxb3 Nxb3 21. axb3 Rc7 ½ : ½ Unzicker – B. Larsen, 12th Chess Olympiad, Moscow 1956. 12. ... Nxf6 13. Ne5 (13. a3!?) 13. ... 0-0 14. Nc4 c5 15. dxc5 Rxc5. Now the Rook can eventually join Queen, Bishops and Knight to attack on the Kingside (... Rc5-h5). 16. e4!? Qc7 17. f3 Rc8?! 17. ... Rd8! (Δ ... Rd8xd3) seems more to the point since 18. b3? would be met by 18. ... Qd7! winning. 18. b3 a5 19. Be3 Rc6 20. Qf2 Nd7 21. Qg3 Bc5 22. Bf2 e5?! Paoli avoids to simplify. 23. Bxc5 Rxc5?! More natural seem 23. ... Nxc5= as after 24. Nxe5?! Re6 would regain his Pawn with interest. 24. Ne3! Suddenly White launches into attack! 24. ... Nf8 25. Bc4 Ng6 26. h4. Suomen Shakki, No. 8, 1978, p. 298, gives – in order to prevent ... Ng6-f4 – 26. Nf5 (Δ h2-h4). Another modus operandi could be 26. Rad1 (or 26. Rfd1), in order to double the Rooks on the d-file. 26. ... Nf4! 27. Nf5 g6 28. Qg5 Rxc4! 29. bxc4 f6! 30. Nh6+ Kg7 31. Nf5+ Kf7. Paoli disdains perpetual check (31. ... Kg8 32. Nh6+). What a fighter! 32. Qh6 Kg8! After 32. ... gxf5 33. Qxh7+ White has nothing more than perpetual check, but Paoli hopes for something more! 33. Ne3 Qb6! 34. Rfe1 Rxc4 35. Kh2 Rd4 36. Red1 Ba6? Correct was 36. ... Qd6 and if 37. Nc4 then 37. ... Qc7 38. Nxa5 Qc2! 39. Qxf4! Rxd1 40. Qxf6! Rxa1 41. Qe6+ Kg7 42. Qe7+ with perpetual check. 37. Rac1 Nd3? The losing move, but after 37. ... Qd6 38. h5! Nxh5 39. Nd5! (threatening both Rc1-c7 and Rc1-c6) Black would be doomed anyway.


38. Rxd3! Or 38. Nd5! Rxd5 39. exd5 Nxc1 40. Qxc1+-. 38. ... Rxd3 39. Nd5! Rxd5 40. exd5+- a4. If 40. ... Bb7 then 41. Rd1! (Suomen Shakki gives 41. h5 g5 42. Rc6, but then 42. ... Qd4! 43. Rxf6 Qh4+ would ensure Black perpetual check) 41. ... Qd6 42. Qe3! with decisive penetration. 41. Rc6 Qa7 42. Rxf6 Qa8 43. Rd6 b3 (43. ... Qc8 44. Qg5+-) 44. Rd7 1 : 0.
