1. d4 e6 2. c4 b6 3. e4 Bb7 4. Bd3 Bb4+ 5. Bd2. Stronger seems 5. Kf1!, e.g. 5. ... Be7 6. Nc3 d6 7. Nf3 Nf6 8. g3 0-0 9. Kg2 Nbd7 10. Qe2 c5 11. d5 Re8 12. Rd1 Bf8 13. dxe6 fxe6 14. Bc2 a6 15. Bf4 Qc7 16. Rd2 Ne5 17. Rad1 Bc6 18. Bxe5 dxe5 19. Ba4 Bxa4 20. Nxa4 b5 21. cxb5 axb5 22. Qxb5 c4 23. Rc2 Rec8 24. b3 Qb8 25. Qxb8 Raxb8 26. bxc4 Nxe4 27. Nxe5 Rb4 28. Nb2 Nc5 29. f4 Be7 30. Nbd3 Ra4 31. Nxc5 Rxc5 32. Rb1 Rc8 33. c5 g5 34. c6 Bd6 35. Nd7 gxf4 36. Nb6 f3+ 37. Kf2 1 : 0 So – Gelfand, ACP Golden Classic, Bergamo 2014. 5. ... Bxd2+ 6. Nxd2 d6 7. f4. For 7. Ne2 c5 8. d5 e5 see Bunzmann – Oral, Budapest 1998. 7. ... Nd7 8. Qg4. Gelfand is playing with fire... Jobava felt that 8. Ngf3 Ne7 9. 0-0 0-0 10. Qe1 was stronger. “White has some attacking chances. You always must look for d4-d5, e4-e5 or f4-f5”. 8. ... Ngf6 9. Qxg7 Rg8 10. Qh6 Rxg2 11. Ngf3 Qe7 12. Qh3 Rg7 13. 0-0-0 Ng4 14. Qg3. On 14. Rdf1 0-0-0 “and I have time for ... Rd8-g8 with a playable position”, Jobava said. 14. ... Ndf6 15. Ng5. A compromising move. Worth considering was 15. Rdg1!? Nh5 16. Qe1 Nxf4 17. Bc2 with a vague compensation. 15. ... h6 16. Nh3 0-0-0 17. Rde1. Jobava then suggested 17. Qe1 – it is easy to agree! 17. ... Nh5 18. Qf3 Qh4 19. Re2. If 19. Qf1 then 19. ... Nxf4! 20. Nxf4 Nf2 (Jobava’s analysis). 19. ... Kb8 20. Bc2. A little better – but not so much – was 20. Qf1 f5 21. Nf3 Qxh3!? (Jobava) 22. Qxh3 Nxf4 23. Qh4 Rdg8 etc. 20. ... f5. “Now it’s not so easy to play because the center is collapsing”, Jobava said. 21. Qf1 Nhf6. Equally strong was 21. ... d5(!). 22. Nf3 Qh5 23. exf5 exf5 24. d5 Re8! “I’m trading one of the most active pieces”, Jobava said. 25. Rxe8+ Qxe8 26. Qd3 Re7 27. Rf1 Ne3 28. Rf2 Ba6 29. Bb3 Nexd5 30. Qxf5


30. ... Bxc4! 0 : 1. For if 31. Bxc4 then 31. ... Re1+ 32. Nxe1 Qxe1+ 33. Kc2 Ne3+ winning the Queen. If, instead, 31. Rd2 then 31. ... Bxb3 32. axb3 Re1+ 33. Nxe1 Qxe1+ 34. Rd1 Qxd1+ 35. Kxd1 Ne3+ and Black ends up with two Knights against one.
