Nc6 Nxd5 18. Nxe7 Nxe7 19. Qxd6 ½ : ½ Mareco – Baramidze, 45th World Junior Chess Championship, Yerevan 2006) 9. ... Nbd7. Of course there’s always a past: 9. ... 0-0 10. f4 Ng4 11. g3 Nxe3 12.

13. g4! A very promising Pawn sacrifice. 13. ... Nxg4. Mareco accepts the challenge and plays the game. If 14. ... h6 there may follow 14. Qg2 Qc7 15. h4 Bxf1 16. Rdxf1 b4 17. Nd5 Nxd5 18. exd5 Rb5 19. g5 Qc4 20. Nd2 Qxd5 21. Ne4 Kd8 22. Rd1 Qc6 23. f6 gxf6 24. gxh6 Bf8 25. h5 Kc7 26. Qg4 d5 27. Ng3 d4 28. Bc1 Nb6 29. Ne4 Nd5 30. h7 Nc3+ 31. Nxc3 bxc3 32. b3 d3 33.

Rdxf1 Bf6 17. Rd1 Nb6 18. Qd3 Ke7. This move — apparently a bit too conservative — is consistent with Black’s plan of “artificial castling”. Better seems 18. ... 0-0 returning the Pawn with good prospects for equality.


19. a3! Re8 20. Nc1. Intending Nc1-a2-b4-d5 — a Karpovian route. 20. ... Qd7 21. N1a2 a5 22. Qxb5 Qxb5 23. Nxb5


23. ... Rec8? Black’s last hope for counterplay was 23. ... d5! (24. exd5 e4!). 24. Nac3 Na4 25. Rd3 Nxc3+ 26. Nxc3 Kd7 27. b3 Rc6 28. Kb2. The position is such that the Knight is far superior to the Bishop. 28. ... Rbc8 29. Rg2 h6 30. Nd5 Bg5 31. a4 Ke8 32. c3 Kf8 33. b4! White obtains two connected passed Pawns. Game over. 33. ... axb4 34. cxb4 Rc4 35. Re2 Rd4 36. Rxd4 exd4 37. Rc2 Ra8 38. a5 d3 39. Rc3 d2 40. Kc2 g6 41. f6 h5 42. a6 1 : 0.
