 | | luzhin: 53..Rd8 54.Bc8 and Black is both buried alive and in Zugzwang. Truly horrible. |

 | | geraldo8187: they need to have a player like andriasian in all these tournaments. certainly makes things more entertaining. |

click for larger viewThis certainly gives Black more play than the game continuation, as the passive Bf8 gets out and covers the Queening square. So after 50. d6 h5 White should simplify with 51. Kg3 Bh6 52. Nxh6 Kxh6 53. gxh5 Kxh5 54. Kf4:

Thank you , that is logical , I overlooked white's option of picking up f pawns first after 52.Nxh6 Kxh6 |

 | | tamar: <tpstar> Black can still draw in your first variation by reaching this tablebase position, I believe.
click for larger viewStarting with <hovik2003> suggestion of 50...h5 51 Kg3 Bh6 52 Nxh6 Kxh6 53 gxh5
Kxh5 54 Kf4 Kxh4 55 Kf5 Rg8 56 Bd5
(Against the natural 56 Kxf6 Rg6+!

Shredder still shows +2.43 for White, but there is no way to
make progress. |

| Oct-20-07 | | hovik2003: So after all Andriasian should have tried 50...h5, instead of that obvious selfbonding move 50...Kg6. I think Andriasian is natural positional player but he should try to improve his middlegame tactics, in all games he lost, his opening phase were good and positions he reached in middlegames were more than OK, but always he blundered before ending duo to oversights and miscalculations.
I think if he practice more pro chess he will be a much stronger player in next 3 or 4 years, and he will be among top 50 GMs in the world. |

| | tpstar: <tamar> Thanks for analyzing this ending. Your 56 ... Rg6+! is a clever resource which easily holds the draw. For the first line, after 55. Kf5 Rg8 56. Bd5 maybe Black should just repeat the position with 56 ... Rd8 57. Bc6 as 56 ... Kg3 57. Bxf7 Ra8 allows 58. Be8
click for larger viewPerhaps I was too cavalier with White's Kingside Pawns, so instead White could try to maintain the bind (and the material) with 50 ... h5 51. gxh5 Bh6 52. Kf3: 
click for larger viewBlack is presently reduced to Bishop moves, but once it reaches a5 that will free the Rook. White could play to win the Pf6 (and hopefully avoid losing) with 52 ... Bd2 52. Ne7 Ba5 53. Nd5 but after 53 ... Kg7 54. Kg4 Rh8 White is stuck (55. Nc7 Rd8). Looks like Black had serious practical chances to hold this endgame. |
