Kibitzer's Corner
May-08-08  Grumpi: Fine light-squared strategy. Black bishop was strangled and lost.
May-08-08  guybrush: I'm probably missing it...but why doesn't 20...d5 solve black's problems?
May-08-08  guybrush: Sorry...I meant 27...d5
May-08-08  Karpova: 27...d5 28.Rb5 dxe4 29.Rxe5
May-08-08  NguyenVo: I think 27...d5 loses a pawn due to 28. Rb5. If black takes 28...de4 then 29.Re5 takes a pawn and forces black to protect the bishop and thus loses another pawn.
May-08-08  AdrianP: A lot of this will have been prep. Cheparinov works hard on both sides of the Najdorf and Bu specialises in this 10. ...a5 sideline in the English attack. But Chep played the late middlegame very well.
May-08-08  Shockwave: nice analysis there warheart. Bu really bollocked it up in this one
May-08-08  crwynn: What I really didn't get was Bu's 31...h5 and 32...Rc7, the move ...Rg8 practically plays itself, and I don't see where White is supposed to have an edge against it.

Basically the h-pawn gets traded for the b-pawn. It seems to me that Bu, with b-vs.-kt in a fairly bad position, should have been happy to turn it from a slow squeeze with himself as squeezee, into some kind of crazy race between passed pawns. I don't know if he saw a line he didn't like, or if he just thought it was too unclear, anyway my computer can't find any problem with this idea.

31...Rg8 32.Ra5 Ra5 33.Na5 is probably better for White than 32.Na5 Rg1 33.Kc2 Rg2, after 33.Na5 Fritz suggests 33...Ke6 34.Rb7 h5, it is hard for White to keep the h- and e-pawns.

May-09-08  Davolni: nice play by CHepa!!!
May-09-08  Pianoplayer: 46. ♖h8!.
May-09-08  Aleksandar Li: This was nice win for Cheparinov. With style against Bu. Congratulations!
May-09-08  kevin86: An odd finish;the bishop is trapped and about to be threatened a second time. The king defends well,but the rooks are nowhere to be seen.

A piece only attacked once,and defended-it DOOMED

May-09-08  Samagonka: Black jumped from the frying pan straight into the fire!
May-09-08  positionalgenius: ulra-class win here from chepinarov. Looks like he feels at home in sofia...
