Mar-09-08  Jim Bartle: For some it's "memorising a 30-move sequence"; for others it's "having good opening preparation."

  ketchuplover: I like 29.Rc7+
Sep-14-08  Underworld: <ketchuplover> 29.Rc7+ doesn't work due to: 29.Rc7+ Bxc7 30.Qxc7+ Ke8 and the trip is over b/c the knight on a5 is proctecting the c6 square needed to do another check. Overall it would be a failed attempt.
Jul-02-11  Kinghunt: Is this the latest novelty there's ever been in a game? Probably not, but I can't think of any games where it was later. I'd much appreciate it if someone could point me to the latest novelty there's ever been.
Premium Chessgames Member
  FSR: Pretty pathetic for a GM to prepare an "improvement" on move 29 and have a resignable position on move 32. Of course, this wouldn't happen these days with Houdini and such.

Have a go at this one: I Novikov vs V Tukmakov, 1984.

  FSR: In the 60s and 70s they called IM Bernard Zuckerman "Zuck the Book." Now every top player has to be _____ the Book.
Jul-03-11  NARC: I have plans to start playing the Meran, but if I have to keep tack of all this in the Botvinnik system first I am having second thoughts.
Premium Chessgames Member
  FSR: <NARC> You can always play the Moscow Variation (5...h6), but that has a lot of theory too.
Premium Chessgames Member
  perfidious: <NARC> An alternative to <FSR>'s suggestion is 5....Nbd7, after which you can transpose to a classical QGD or play the Cambridge Springs with 6.e3 Qa5.

If you play the Moscow line, Alexey Dreev 's games are well worth studying, as this has long been a speciality of his for Black.

Oct-03-11  DrMAL: Back-to-back duet for theoretical deul of Botvinnik variation (round after Kasparov vs G Timoshchenko, 1981) where, from new tabiya after 30.Bxa7 black played 30...Be5 that was topic of hot debate led by Sveshnikov who was hammering on how it should win. See other game for more on this move, second best to 30...e5 originally played, and hence losing faster. Computer line repeated here.

Houdini_20_x64: 27/72 59:41 32,070,400,180

-1.20 30. ... e5 31.Qa2 Rd1+ 32.Rxd1 Qxd1+ 33.Kg2 Nb3

-2.03 30. ... Be5 31.Rc5 Rxc5 32.Bxc5 Rb8 33.Qd3+ Kc6

Comparing to computer line shows further inaccuracy with 32...Nc6 and 33...Kc8 pair as inaccuracy. But, little to his knowledge then, black was lost to begin with, Sveshnikov and his supporters were wrong and teenager Garry was right in playing what he did.

While thinking about this game in-between rounds in the middle of the night between the two, Kasparov realized that 32.Bxc5 (not Qxc5) was the answer. As one might expect he was right he found the refutation to 30...Be5 through this move.

Houdini_20_x64: 24/63 03:16 1,774,757,203

+1.56 32.Bxc5 Nc6 33.Qd3+ Nd4

0.00 32.Qxc5 Nc6 33.Rb7+ Bc7 repetition

Game starts after discussion about half way through video or get DVD #2 (or all five DVDs) of My Story (e.g., I highly recommend watching entire series.

Oct-03-11  anandrulez: Is Garry's sacrifice correct especially Nxc3 ?
Oct-03-11  DrMAL: <anandrulez> Most definitely, please see earlier game with Timoshchenco (and one with Tal) for more on that, cheers.

  SpaceRunner: 13..-, Nxf6!
Apr-21-17  Howard: Both this game and its "predecessor" are analyzed thoroughly in Kasparov's book of his best games during this period.
Aug-02-18  Ironmanth: Surgical and beautiful! Thanks for this one, chessgames.

  HeMateMe: Isn't Frunze the location of a high level Russian military academy? I think it's their officer's school or a FSB training school.
Aug-02-18  Strelets: That one is in Moscow but, like the city of Bishkek during the Soviet period, also takes its name from the same guy.
Aug-02-18  lzromeu: Usually, castling goes to a double rook. This one by black goes to nothing.

Aug-02-18  The Kings Domain: Impressively deep victory by the young Kasparov.

  Breunor: It looks like stockfish views 26 … Bxd6
as the move giving white a big advantage.

1) +1.45 (30 ply) 27.Rc1 Qb7 28.b4 Qxb4 29.Rb1 Qg4 30.Bxa7 e5 31.Qa2 Rd1+ 32.Rxd1 Qxd1+ 33.Kg2 Nb3 34.Qxb3 Qxb3 35.Rxb3 Ke6 36.Be3 Kxf6 37.Rb6 Ke7 38.Bg5+ Ke6 39.h4 f5 40.Kh3 Kd5 41.Ra6 e4 42.Bf6 Re8 43.Ra5+ Ke6 44.Bg7 Rg8 45.Bd4 f4 46.g4 Ke7 47.h5

although Cormier's analysis with Houdini giving a different view may be more accurate.

Black stays even with Nc6 instead (according to SF)

=0.00 (31 ply) 26...Nc6 27.Rc1 Nd8 28.h4 Ke8 29.Rd1 Rxd1+ 30.Qxd1 Nc6 31.Qc2 Kd7 32.Qd1+ Ke8

Stockfish does not like the improvement 30 ... Be5:

1) +2.47 (29 ply) 31.Rc5 Rxc5 32.Bxc5 Rb8 33.Qd3+ Kc6 34.Qa6+ Kd7 35.Rxb8 Qd1+ 36.Kg2 Qd5+ 37.Kh3 Bxb8 38.Qxa5 Be5 39.Qa4+ Qc6 40.Qxc6+ Kxc6 41.Be7 Bd4 42.f3 Bg1 43.g4 Be3 44.Kg2 Kd5 45.h4 Ke5 46.g5 Kf5 47.Kg3 Bf4+ 48.Kh3 Bc7 49.Bc5

Instead, it prefers e5

1) +1.57 (29 ply) 30...e5 31.Qa2 Rd1+ 32.Rxd1 Qxd1+ 33.Kg2 Nb3 34.Qa4+ Ke6 35.Qc4+ Qd5+ 36.Qxd5+ Kxd5 37.Rxb3 Ke6 38.Be3 Kxf6 39.Rb6 Ke7 40.Bg5+ Ke6 41.h4 f5 42.Kh3 Kd5 43.g4 Rf8 44.gxf5 Rxf5 45.Be3 Bc7 46.Ra6 Rf7 47.h5 Ke4 48.h6 Kf5 49.f3 Re7 50.Kh4 Bd8

Jan-07-19  John Abraham: the Semi Slav is such a deep and complicated opening
Jun-28-19  Howard: This is not exactly important, but Soltis mistakenly stated in a January, 1983 column that these two "twin games" took place in...1982. But it was actually 1981! Not only that, Shamkovich made the same mistake 1-2 months earlier in a CL article.
Nov-08-20  fisayo123: 30...Be5 was apparently suggested by Sveshnikov in the post mortem of Kasparov's brilliant victory in the last round. Kasparov vs G Timoshchenko, 1981

Actually 30...e5! played in that game was much stronger than 30...Be5. An incredible occurence in chess history when you get pretty much the same game up till move 30 in back to back rounds. Of course Garry wins both games in fine style!
