Mar-11-05  Seraph88: how does bronstein win?
Mar-11-05  admiralnemo: 46...d2
Mar-11-05  beatgiant: <admiralnemo: 46...d2> 46...d2 allows 47. Qc3+ picking up the d-pawn. There has been discussion above that the final position looks winning for White.
Mar-11-05  admiralnemo: good golly, beats the hell out of me then
Mar-11-05  Seraph88: so no one knows?
Apr-10-05  Badmojo: Crafty's lines are right.

The King goes to d2 - game over.

Jul-01-05  supertimchan: Did windows crashed or it should be 1-0?
Jul-01-05  vampiero: but after black plays d2 white plays Qc3+ and wins the d2 pawn and then the e2pawn
Oct-20-05  THE pawn: The problem here is still not solved this game is a win for white.
Dec-31-05  CowardlyKnight: 72 year old Bronstein pounding on the machine like there's no tomorow.
Apr-11-06  chessmoron: i can't believe the Deep Blue forfeit which the computer has a huge advantage of winning. (how stupid)
Aug-02-06  gambitfan: You have Black and your opponent opens with : 1 b4 !? This the so called Sokolski or Polish opening...

This is very uncommon opening ( Uncommon Opening (A00) ) and you might be at first dazzled by such a weird move...

Let us call great players to your rescue in order to give you some hints...

First let us see how Bronstein (Black) was able to beat Deep Blue playing this weird opening move ; Bronstein plaaaays the "Czech" defense : Deep Blue vs Bronstein, 1996

Last but not least let us see how Ponomariov plays (and wins !) the most "classic" defence against 1 b4 !? : V Akobian vs Ponomariov, 1995

Aug-02-06  suenteus po 147: <gambitfan> Rule #2 of the posting guideline specifically states no duplicating posts.
Aug-02-06  gambitfan: Bronstein (Black) wins with 46... d2 !

How can White (Deep Blue) prevent either d2 or c2 to queen ?

No way !

Nov-07-06  whatthefat: <chessmoron>
Obviously either the score's wrong, or white ran out of time.
Nov-07-06  Fisheremon: A bit strange with Deep Blue. A guess: at the end of game he wanted to force draw by perp. , when Bronstein denied this a bug might be happened with DB.

After sac 14...Rxa2 there are two moments worthing discussions:

1) On move 19 could Bronstein play 19...c6 ? Then 20. Qa4 Qc3 21. Qc3 Qa1 forces Queens exchange (it's not a variation of Bronstein style).

2) Where was Black's initiative slipped away ? I should think it was 25...g5. With Bronstein style of thinking one might suppose he thought of a plan how to put his Bishop to h6, but lacking a temp to do that. I would propose the following variation of attack:

25...f5 26. g3 Qh6 27. exf5 Bxf5 28. h4 Qg6 29. Kf2 Re8 30. h5 Qg5 31. f4 Qe7 32. Rhe1 Qe3+ 33. Kg2 Qd2.

Nov-26-06  rizhanin: Certainly,the result of the game is incorrect.d2 looses elementarly either to Qc3 or Qb2,check.I have also read a book by Bronstein,where this game was commented.Unfortunately,DB-man was defeated by DB-program this time.
Dec-08-06  aazqua: what is wrong with r*r on move 27??
Jun-13-07  im a person: it woulda been funny if there was a DB vs. DB
Jan-02-10  DoneMac: A brilliant lost, I have no idea how Super GM David Bronstein even played this way never mind the fantastic game continuation of 27...Qd2 I would've just played 27... Rxb8 with a slight edge to Black ...I don't have the original game score but 41... Ba3 should hold (with care) as well as 41...Bb4, Bc4 a tricky counterattack - even Bh6 seems to hold... the problem (for Black) is 43... Kg8?? when Kh6 is equal -- White can only prepet 44.Qh8+ (etc) because at least one pawn Queens (with check) ... in the final position Black cannot play 46...d2 since 47. Qb2+ wins the unprotected c-pawn -- so in the end, it was age that caused an oversight that lost - as the previous play was just spectacular!
Jan-02-10  AnalyzeThis: Only a terrific defender holds this with white. Deep Blue certainly was that.
Nov-12-10  Xeroxx: Well calculated by the computer.
Aug-05-11  Everett: <Fisheremon:

I like 25..Ra8 or 25..Ba3

<aazqua: what is wrong with r*r on move 27??> I'm sure my line has some holes in it, namely white's first two moves, but <27..Ra8 28.g3 Qe3 29.Qc1 c2 30.Qxc2 <Qxe3 cxb1=Q+> Ra2 31.Rb2 Bh3+ 32.Ke1 Bb4+ 33.Kd1 Ra1+ 34.Rb1 Rxb1+ 35.Qxb1 Qd2#> looks like fun.

Feb-28-17  jordian: 46.d2 loses anyway...

47. QC3 (or even B2)...check, king moves away, queen takes C pawn

Apr-24-17  rwbean: Black gradually threw that away - 46 ... ♔h6 still draws.

23 ... ♖a8 or 27 ... ♖xb1+ would have been decisive.
