Aug-27-04  Whitehat1963: What a wild game!

  An Englishman: Good Evening: The key move is 15.Bg5, which looks like an oversight at first blush. Then White follows with 16.Bb3, which looks like an even bigger oversight. I wonder when Black realized that White had made those moves on purpose.

  keypusher: Gheorghiu-Ljubojevic is identical to this game through white's 18th move. Ljubojevic won in 25.

Gheorghiu vs Ljubojevic, 1973

So yes, it does look as if Bronstein did some serious work on this game beforehand.

Mar-24-05  Broon Bottle: Dear An Englishman, 'realised' is generally spelt with a c in British English.

  TheAlchemist: <keypusher>

As far as I know it was Ljubojevic who was the better prepared before this game, but missed 18...Qc5! (18.Ke2 is a mistake, better was 18.O-O-O). Bronstein was in serious time trouble, that's why Ljubojevic kept playing on even in a desperate position.

So, obviously, the game with Gheorghiu was played after this one.

  keypusher: <Alchemist>, you are right! I assumed that Bronstein-Ljubojevic came later because Bronstein varied first, with 18 d6. But apparently not.

  TheAlchemist: Oops, I meant 19.Ke2 Qc5 in this game. I got confused with the moves in the game with Gheorghiu :(

However, I still think this game was played before, because 19.Ke2 is a mistake, so obviously 18.Ke2 (Gheorghiu) is a mistake too. And Ljubojevic would have known Qc5 was better than Bc5. I hope I didn't confuse you :)

  keypusher: I couldn't find a date for the Manila tournament on the web (Petropolis was in July-August) but a webpage devoted to Ljubo confirmed that the Bronstein game came first.
Jul-21-05  PivotalAnorak: Yes, Bronstein-Ljubo came before Gheorghiu-Ljubo. But first came Ljubojevic vs K Honfi, 1970, nice attack (14... Qc7? refuted by 18.Rg8+!) by Ljubo who thought he could improve Black's play here with 14...g6. Not so...
Aug-22-05  Ulhumbrus: On 14...Nc6 the d5 pawn is pinned and so cannot take the N
Oct-26-05  azaris: Bronstein gives 19 O-O-O! Bc5 20. e6 fxe6 21. Qe5 Re8 22. d7! as winning, but I fail to see how. Any ideas?
Oct-26-05  nescio: <azaris: Bronstein gives 19 O-O-O! Bc5 20. e6 fxe6 21. Qe5 Re8 22. d7! as winning, but I fail to see how. Any ideas?> No, I don't see it after 22.d7, but 22.Bh6 Qd7 23.Ne4 looks like an improvement. I also wonder about 19.0-0-0 Qc5 20.e6 N8d7.
Oct-31-05  aragorn69: Interesting analysis and context at http://www.chesscafe.com/Reviews/bo... (which is a review of "Chess Brilliancy" by Iakov Damsky)

  Open Defence: <all> Keres gives 190-0-0! ♗c5 20e6! ♘8d7! 21e7! or 19...♕c5 20e6 ♘8d7 21exf7!

or even
19.. ♘8d7 20♖xg1 ♕xc5 21♖e1 ♖ae8 22e6!

Nov-01-05  who: <Broon Bottle> realized with a 'c'?
Nov-01-05  csmath: Critical, missing from analyses is the following (given just briefly by Bronstein):

18. ... Qc5

19. Ne4 ... Qd4

(anything else loses too)

20. Rd1 ... Qxb2

21. Nf6!! ... Kh8

22. Rd2 ... Qc1 (see further for 22. Qa1)

23. Kg2! ... Bc5

24. Ne4!! ... Nbd7

25. Bf6 ... Nxf6

26. Qxf6 ... Nc4

27. Bxc4 ... Qxc4

28. Bb4 ... Qe5!

29. f5 ... exf8Q+

30. Rxf8 ... Nf6

31. Rxf6 ... d7!

and black does not have much to hope for.

Or black has probably a better option in

22. ... Qa1

23. Bd1!! (covering a-rank) ... Be3 (this is sorry choice but there is nothing better)

24. Qxe3 ... Nc4

25. Ng4 ... Nd7

26. Qd4 ... Qxd4

27. Rxd4

Black has defused the attack of white but at the price. The ending is now complicated but white is the one playing for a win here.

Anything I am missing here?

Jan-31-06  Whitehat1963: Wow! Now this is interesting and exciting!
Apr-01-06  DeepBlade: 12. ...Nc6! would be a great line in this game, dont you think?

Premium Chessgames Member
  keypusher: <DeepBlade> looks interesting, but hold the exclamation points...

13 Qe4 Nb4 and then maybe 14 Be3 to cover ...Qh4+ and threaten a3, Bxb6 and Bxc4, and 0-0-0. What should Black play after 14 Be3?

Apr-02-06  DeepBlade: True, the exclam was for the thrill of seeing such move, and ofcourse pawnxN results to QxQ.

I would play 14. ...N6xd5, but

14. ...N6xd5 fixes the Bxb6 threat

14. ...N6xd5 15.Bxc4 would kinda soften White's pressure if you consider 15. ...Nc2+ 16.QxN Qh4 17.Bf2 Qxc4 but in this line Black is toasted 15. ...Nc2+ 16.Ke2 Nxe3 17.Bb5+ Ke7 18.Rad1

Casteling, with a exchange sac for a dominating center control with the minor pieces. 14. ...N6xd5 15.0-0-0 Nd3+ 16.Rxd3 cxd3 17.Nxd5 Rc6+ 18.Kb1 Bc5 and White controls the center with minor pieces.

The 14. ...N6xd5 15.a3 threat is easly parried with 15. ...Nxe3 16.axb4 Qb6 17.Ra4 Be7, and now Black is a lot saver, and can get its 2 rooks into play by casteling. Only in this a3 variation Black can get the upper hand.

About the game: 18. ...Qc5 followed with Q-checks would be more appropiate, a little dangerous but the attack can be defended.

32.Ng4 would really help Bronstein and 34.Nh5+ would do good too.

  keypusher: <DeepBlade> Thanks for further analysis (I play this line myself). I agree that 15 0-0-0 is best (winning?) for White, since he gets two pieces for the rook plus the dominating center. a3 turns out to be not a threat at all.

  IMlday: I like this game a lot!
Apr-12-06  MorphyMatt: is 26... ♕xb3+ forced?
Sep-13-06  talisman: what does white get for the rook?developement,possibilities,no mating attacks,some kind of 16th move!
