Apr-21-08  whiteshark: position after <18...Bc6>:


click for larger view

All engine opening books suggest only 19.Ne2, whereas imo <19.h6> fits more the 'all-or-none> character of the position.

Apr-21-08  positionalgenius: Grischuk played the french!? Wow that definitely took his opponent by surprise.
Apr-21-08  kingsindian2006: forcing the queen to move in a place where the trade works out well for black is sweet to watch. and move 30. ..rxd3 is good defense.
Apr-21-08  veigaman: <Wow that definitely took his opponent by surprise.> The talent beats the opening cook!
Apr-22-08  urnebes: Cheparinov is trying hard to play like Topalov. Hopefully, one day he actually will succeed.
Apr-22-08  Orlin Burov: Cheparinov should be a bit wiser and find his true self. Hope he does better sooner or later
Topalov shouldn't be the sole model.
Apr-23-08  KarAkter: 13.Qc3 is better for white here.On 19.h6 Rg6 20.h7 Rh8 21.Qd1 Rg7 22.g4 Ne7 23.Lc4(or 23.Ld3 Ng6 24.Lc4) dc4 24.Rc4 Rgh7=.On 19.Ne2 Lb5 20.Nd4 looks better than a4.Interesting looks 27...d2+ 28.Kd1 Ne4 29.Rf3 Nf2 30.Rf2 Ne3+ 31.Ke2 d1=Q 32.Ke3 Qd4+.Anyway,good game for Grischuk
Apr-23-08  Marmot PFL: <whiteshark> 19.h6 has been played, and seems OK for black. D Tebb vs G Quillan, 2006
Apr-23-08  Marmot PFL: Maybe Cheparinov should have played 21.Ba3 like my old friend Rajlich. V Rajlich vs E N Cooke, 2001
Apr-24-08  KarAkter: If 21.La3 Lc6 22.Qc3 Qa7 23.a5 Rg4!(instead Nfe3?)24.h6(Lc1?)Rh8 25.Rc4 dc4 26.Qc4 Qb8 and black is more than OK.

  al wazir: After 27. Bxc5 there is again a flurry of exchanges, and now I think white wins the endgame. For example, 27...dxc2 28. Ne2 Rd1+ 29. Kf2 c1=Q 30. Nxc1 Rxc1 31. Rxg3 Nxg3 32. Kxg3 Rxf1 33. Kg4.
Apr-24-08  KarAkter: On 27.Lc5 dc2 28.Ne2 Rd1+ 29.Kf2 black have Rd2!:And now 30.Rg3 c1=Q.Black is better

Apr-25-08  KarAkter: Bitte schön! :)

  Mateo: 21.Qc3 (?) seems to be a blunder losing the exchange without sufficient compensation. Better, for instance, 21.Bd2.
Apr-28-08  PinnedPiece: 17 removals by move 32, and no way for the white knight to protect white's one hope of a queening square after the dust settles.

I wonder if 30. d4 would have improved things for white?

Apr-29-08  minasina: Rybka anlysis sample http://chessok.com/broadcast/live.p...
Mar-04-09  Samagonka: Cheparinov's tactics in this game remind me of Fischer.
Mar-04-09  kevin86: What a pawn race! I guess black will win that one as white cannot protect his staid pawn forever. Meanwhile,black's one pawn can divert the foe while the other is in reserve,ready to win later.

Note the kings! White's has nothing to do;black's is ready and willing to gobble up the pawn and then to assist his own.

Mar-04-09  swordfish: Samagonka: Cheparinov's tactics in this game remind me of Fischer.

Except that Fischer's were usually successful.

Mar-04-09  WhiteRook48: why resign?
Aug-01-09  kurtrichards: Surprise, surprise, surprise....who would think that Grischuk would do a bit of Uhlmann?
Aug-28-10  rapidcitychess: <Whiterook48:<Why resign?>> Because he was losing.
May-23-11  Eisenheim: why not play 42...ke6, then if 43 Nd6 threatening a fork if KxP, black can suprise with 43 ...rxh7 44 bxh7 kxe5 losing the exhange but leaving a horse and three (two) pawns versus a horse and a bishop. drawish at least for black

  Sastre: If 42...Ke6 43.Nd6, Black has 43...f6 44.Ba2+ Nb3 45.Nxb7 Kxe5 .
