After 15.a3 the main line is Rab8 16.Bd3. Now black has a choice whether to play 16...b5, 16...Bc4 or even 16...a6.
a) 16...b5
This is one of the lines which at least made it into WWTD2, if even only as a small comment. After 17.Qg5! many often cited lines are known to be bad for black. The less known idea 17...Qd8, as given in WWTD2 seems to fail after 18.e5! according my analysis with similar lines as 17...Qc7 18.e5. If black wants to switch back to the 16...a6 line with 17...a6 and the idea of 18.Rh2?! Rc5! with a lot of counterplay, he has to reckon with 18.f4!
After
16.-b5 17.Qg5, I tried to revive the black side with the exchange sac
17.-Rc5!? 18.Bc5: dc 19.Qc5: Nd7 20.Qb4 Qb6 21.Nd5 Bd5: 22.ed Nc5 which had turned out well for Black in a game played in 2004:
23. Rh3 a5 24. Qf4 b4 25. a4 Nxa4 26. Rdh1 Nc3+ 27. Ka1 Nxd5 28.Qh2 f5 29. Rh8+ Bxh8 30. Qxh8+ Kf7 31. Qe5 Nf6 32. Bc4+ e6 33. Bxe6+ Kg7 34. g4 fxg4 35. fxg4 Re8 36. Re1 Qb8 37. Qd4 Qd8 38. Qe5 Qb8 39. Qd4 Qd8 40. Qc4 Qd6 41. Kb1 Nd7 42. g5 Ne5 43. Qh4 Qxe6 44. Qh6+ Kg8 45. Rh1 Nf7 46. Qh7+ Kf8 47.Rf1 Rd8 48. Qh4 Kg7 49. b3 Qe2 50. Qh1 Re8 51. Rd1 Rc8 52. Rc1 Qd2 53. Qh3 Qc3 54. Qe6 Rc6 55. Qe4 a4 56. Rf1 axb3 57. Rxf7+ Kxf7 58. Qd5+ Ke7 59. Qe4+ Kf8 60. Qf4+ Kg7 {0-1 Atakisi,U (2325)-Citak,S (2153)/Antalya 2004})
In my corr game I was surprised by
23.Bg6:!! (I could not believe that this can work, but it seems to win by force)
23... fxg6 24.d6! exd6 25. Qg4 b4 26. Qc4+ Kf8 27. Qf4+ Ke7 28. Rh7 Rg8 29. Re1+ Ne6 30. Qg4 d5 31. Qxg6 bxa3 32. Rxg7+ Rxg7 33. Qxg7+ Kd6
34. Rxe6+ Kxe6 35. Qg6+ Ke5 36. Qxb6 axb6 37. bxa3 1-0 Does anyone else have experiences with the exchange sac 17.-Rc5 ?
Is this line analysed in any dragon book?
