Dec-15-06  mig55: 34...e1Q
35. Kg2/Qg4
36. Qg8/ Qh3

usw....

Dec-15-06  VargPOD: I found 30...e2, and followed it to 34.g3 e1Q+ and thought that was it. The underpromotion looks like a whole different part. Not a very good puzzle, I think.
Dec-15-06  Phony Benoni: Bronstein annotated this game in "The sorceror's apprentice". It seems that both players were in severe time trouble during the last ten moves or so. Some of his points:

1) 30.Rd5 was a bad mistake. 30.Rd1 probably leads to a draw, but neither player was interested in drawing.

2) 34.Rd1 exd1Q+ 35.Bxd1 Qd2 36.g3 Qxd1+ 37.Kg2 Qd8 38.h4 would have given WWhite slight chances to draw.

3) 34...e1Q+ would have won easily, but in time trouble Bronstein went for a series of forcing checks. He gives the line 34...e1Q+ 35.Kg2 Qg4 36.Rd8 Qh3+ 37.Kf3 Qh1+ 38.Ke3 Qe6+ (in a slight typo, which queen is not specified).

4) White could have won with 39.Qf4+ g5 40.Rd6+ Bxd6 41.Qxd6+ Kg7 42.Qe5+ Kg6 43.Qe6+ Kg7 44.Qf5 Nxa2 45.Qxg5+ Kf7 46.Qxh5+, when his passed pawns should triumph once the queens come off. White missed 39...Kxh5!, thinking that 39..gxf5 40.Qe6+ winning was forced.

Dec-15-06  TrueBlue: well, e2 was obvious, the rest is just technique.
Dec-15-06  MenisfromVenis: Thought 30...exf2+ was the winner (Q + R under attack, so start with a check). Should have known it was too simple.
Dec-15-06  dakgootje: Awwwww missed Bc2, so got the general idea and first moves, but far from solving it
Dec-15-06  CoryLetain: After e2 I couldn't tell if black could escape the coming queeen check. I did finnaly decide on e2 and got pretty far but I didn't see the underpromotion. Wow.
Dec-15-06  zb2cr: I hesitated to play 30. ... e2, since it gave White the capture of the Rook with check. I couldn't follow it all the way. So I tried 30. ... exf2+.
Dec-15-06  manbot: amazingly i actually found this. although i wasnt sure it was going to be right be cuase i didnt see quite far enough. but i still couldnt find anyhting better.
Dec-15-06  YouRang: <TrueBlue: well, e2 was obvious, the rest is just technique.> Yeah, same here.

Some techniques just take longer. Months maybe.

Dec-15-06  who: <Good Evening: I don't think anyone can say they got it right if they didn't see the underpromotion seven moves into the combination. That's why I rejected 30...e2 in favor of 30...exf2+. Weird thing is, it might work (of course, I'm working without the benefit of a chessboard or software, as usual). 31.Kxf2,Qf4+; 32.Ke1 (Kg1,Bc5+),Bh4+; 33.Kd1,Re1+ might be a winner.

The tough line is 30...exf2+; 31.Kf1,Qc1+; 32.Kxf2,Bc5+; 33.Qxc5 (Rxc5!?),Qe1+; 34.Kf3,Qe2+. Would someone mind terribly running this past one of their silicon monsters and showing how wrong I am? Thanks.> Here are the computers suggestions.

34.g3? -3.03(34.Rd1 exd1=Q 35.Bxd1 Qd2 36.g3 Qxd1+ 37.Qe2 -1.63) (editors note - they both look losing though Phony Benoni says that Bronstein thought that white may have a chance to draw here).

34...Qc1+? (if you played this move as part of your combination you didn't get it) +1.18 (34...e1=Q! 35.Kg2 Qg4! (only move) 36.Qg8 Qh3! 37.Qf3 Qh1+! (only move) 38.Ke3 Qe6+!! (only move - phony there is only one queen that can do this) 39.Qxe6 Qe1+ -3.63) 39.Rxh5? (this sac is very unsound. There are four drawing moves and one winning one) -2.47 (39.Qf4+ g5 40.Rd6+! Bxd6 41.Qxd6 Kh7 42.Qc7+ Kg6 43.Qb6+ Kf5 44.cxb4 +1.03) 39.cxb4, 39.Rd7, 39.Rd8, and 39.Rd4 all draw.

Dec-15-06  who: Incidentally, judging by Phony Benoni's quote it looks like Bronstein figured this all out when analyzing later without a computer.
Dec-15-06  Ashram64: i saw e2 with ease and also saw a few following up moves. however, after i saw the real game play w/ all the underpromotion and checks I realized how complicated was the game. Every move counts not materials. I just got lucky for friday
Dec-15-06  kevin86: What a great game! Black is faced with a queen and rook under fire-and he moves a pawn!! A few moves later,he underpromotes said pawn to a knight! Such a game calls for a brand new collection of games-of the highest standard!
Dec-15-06  NBZ: Phony Benoni's post certainly explains a lot.

Lol I was feeling very clever about myself (I saw something Bronsein didn't!) but not any more.

Ah well, there is always Kramnik's Qe3 to console me...

Dec-15-06  karnak64: Absolute wizardry.
Dec-15-06  Maatalkko: Actually this is a very simple puzzle. All you have to do is see that there are no further checks after 33.Kh6 and then you're done. These players' later moves are superfluous and a result of zeitnot, as expalined by <Phony Benoni>.

Moves 11-27 are some real wizardry. I don't know if those moves were best but I couldn't have found them. It seems that White turned down several opportunities for perpetual check, but he did have an advantage back then, I think.

Dec-15-06  Maatalkko: Actually, if you saw the underpromotion then you goofed up, because simply making a Queen is much cleaner!

  playground player: Oh, yeah--push the pawn!
Dec-15-06  Mendrys: The under promotion was a blunder on Bronstein's part. White should have won after the underpromotion but 39. Rxh5?? loses outright. Cherepkov had counted on 40. Kg5 Qxe7+ picking up the knight and overlooked 40. Kg4.

Both players were under extreme time pressure so the mistakes are certainly understandable.

Dec-15-06  DeepThought: I got the line up to 32. ...g6 and later e1Q+

When I saw the game, first I was shocked about the queen check on 34. ...Qc1+ and the underpromotion to knight, but e1Q+ (as I had guessed) would have won outright after 34...e1Q+ 35.Kg2 Qg4 36.Qg8 Qh3 37.Kf3 Qh1 38.Ke3 Qe6+ 39.Qxe6 Qe1+

Dec-15-06  ValmonUni: found the move and most of the continuation.. didn't see the underpromotion coming though... very nice puzzle
Dec-15-06  Larsker: <The underpromotion was a blunder on Bronstein's part.> Sneaky - you need a new game collection: "Silly underpromotions" :-)
Jan-31-11  Whitehat1963: Oh my! Absurdly complex!
