Kibitzer's Corner
< Earlier Kibitzing  · PAGE 2 OF 2 ·  Later Kibitzing>
Apr-18-05  tacticalmonster: I agree with dac1900. I think every move loses with black to move. If the king move, Rc7+ lose the bishop. a4 is responded with a3. Bishop has no good square to move. That only leaves the R on g8. However, the R moves also loses. The rook can only move around 8th rank. But once the rook leave the g- file, the king will invade the king side and attack the bishop and help support the pawn. Black bishop is quite vulnerable as it does not have too many good square to travel around While white knight will stay where it is to blockade everything. After the white king infiltrate, black position collapses. A strategic masterpiece by white.
Apr-18-05  The beginner: Nice win by Yassar.

The position after the exchange of Queens.

19 Qd4 ..Qxd4
20 hxd4 .. e4

Dosent look to good for white from my point of view. Black's double threat Bxa1, or exd3, with the posibel new threat e2 threatening the other rook, or taking the bishop, undoubling the pawns, if white try to move his rook into safety.

I think i woulda played something different, in a situation like this. So i tryed to play it out against fritz8, just to see what happens :)

21 f6 Blocking the threat, and threatening blacks bishop the idea is to come out even material, black take my bishop, and i take his.

21 f6 ..exd3
22 fxg7 ..Rfe8

To bad is that after this, black has undoubled his pawns and after he put a rook behind the d pawn white will get a hard time to stop them.

Or how about, 21 Nxb6. I meet the threat by winning a pawn, and forking blacks rook, and bishop.

21 Nxb6 ..exd3
22 Nxa8 ..Rxa8
23 Rab1 ..d2
24 Rfd1 ..Re8

White is lost, he cant stop the pawns now, or he must lose a rook and play the endgame 1 rook vs rook + 2 bishops.

Anyway After Yassar plays Be2 the game is almost draw acording to Fritz. The losing move seems to be Blacks 32 ..f5.

Apr-18-05  necrosis: I think the main problem for black in the final position is that his bishop is lost - white threatens Bb6+ followed by Rc7+, and he still maintains protection over the b pawn after taking the bishop on a7.
Apr-18-05  Marvol: <necrosis: I think the main problem for black in the final position is that his bishop is lost - white threatens Bb6+ followed by Rc7+, and he still maintains protection over the b pawn after taking the bishop on a7. >

You are right, white also has a threat if black forfeits his move. So, this position is not a Zugzwang, because in Zugzwang it is the moving that makes the position lost.

Apr-18-05  Hoozits: Was 19. Qg4 a blunder?
Apr-18-05  Mislav: Wow, very deep game!

  kevin86: It looks like a massive exchange in the offing at c8=The result would leave white's advanced king side pawns to queen-eg.

42...♖(g)xc8 43 bxc8(♕)+ ♖xc8 44 ♗xc8+ ♔xc8 45 f6 ♗g8 46 h6 and queens

I believe Yaz hit .321 with 44 HR and 126 RBI in 1967-just one year after Frank Robinson hit a triple crown for the World Champion Orioles in 1966. It has not been done since.

Ted Williams did it twice,just missing by a fraction of a percentage point of a third;Rogers Hornsby also did it twice,hitting over .400 in each

  kevin86: correction for Yaz:.326 and 121 RBI,the 44HR tied Harmon Killebrew.
Apr-18-05  JohnBoy: <Hoozits> - I don't think that 19.Qg4 was a blunder. Looks like a VERY well considered x-sac. That white can free up the q-side while blockading the black pawns on white squares is deep. Once the white king is at f4, it looks as if all of the winning chances belong to white.

This is an excellent choice for game of the day.

Apr-18-05  Madman99X: On the surface, it seems like black blunders with 32... f5?

Chessmaster 9000 suggests Rc8, but after about 20 moves worth of blood, sweat and tears, white just has too many openings. One possible line might be:

32.... f5
33. Bc2 Rf8
34. c5 dxc5
35. d6 Rd8
36. Rd1 Rd7
37. Nc4 Re6
38. a4 e3
39. Bxh7 e2
40. Re1 Kxh7
41. Kf3 Rg7
42. Rxe2 Rxe2
43. Kxe2

and white has one too many passed pawns. I have to agree with JohnBoy. (and disagree with my computer) Qg4 seems a brilliant move, and not a blunder.

Apr-18-05  Everett: I would like to think that I brought this game to chess games attention by asking about it on the Kozul page. It is from Watson's "Modern Chess Strategy" book.

I think Yaz found improvements for white, one being 24. Kg3. I haven't looked at it yet. Perhaps, at first glance, it keeps the black bishop on the Q-side... Leaving his rook the open h-file after 24...hxg4 25.Kxg4

Apr-18-05  Hidden Skillz: hmm how does Bxa1 lose?? im not convinced this position is lost for black..
Apr-19-05  The beginner: <Hidden Skillz>

I Dont understand how it loses eather, but i think maybe, it takes all hopes for black to win the game away. It seems more like a draw, or if one side has to win, it could only be white.

After 32 Bd1 Black's pieces are all locked up, it seems his only manuvering are to move his rook back and forth on the 8 rank. Maybe in a position like this white has the advantage with a knight since it is the only piece who can capture one of the backward pawns, with posibilitis to break through blacks defence. Obviusly Black must have miscalculated something when he played

32 f5 ?

Maybe he was just tired with this kind of locked position, I know from my own games it can drive me nuts lol :) He think he has the better pieces with his two rooks, but he cant use them because the position is so locked up. So he tryed to force things open, or something like that.

Apr-20-05  Hidden Skillz: <the beginner> yes i thought black has a draw at least..but a loss?? lol never
Apr-21-05  Everett: <The beginner>, <Hidden Skillz> I guess black felt the way you did also. Perhaps you should research to see if Kozul comes up with any ideas how to get his bishop and rooks involved without letting in pawn breakthrough on the Q-side.
Apr-21-05  Everett: Oh, and apparently not "never"

  patzer2: In the final position, play might have continued:

42...Rgxc8 (42... a4 43. f6 a3? 44. Bb5#) 43. bxc8=Q+ Rxc8 44. Bxc8+ Kxc8 45. f6 Kd7 46. Kg5 Ke8 47. Kh6 Kf7 48. Kxh7 Kxf6 49. h6 Kf7 50. Nc4 e3 51. Nxe3 a4 52. Nc4 a3 53. Nxd6+ Kf6 54. Kg8 1-0

  patzer2: Two consecutive mistakes by White, 32...f5? and 33...Rg5?, enable Black to play the brilliant winning positional pawn sacrifice 34. c5!

Instead of 32...f5?, Black should have played 32... Rc8 33. Bc2 Rc7 34. Re1 Kg7=.

Instead of 33...Rg5?, Black needed to try 33... fxg4 34. Nxg4+ Rxg4+ 35. Kxg4 Rg5+ 36. Kf4 Rf5+ 37. Ke3 Rxf1 38. Bxf1 Kxh5, when Black has practical drawing chances in the Bishop ending.

May-02-05  Everett: <patzer2> <Two consecutive mistakes by White> by black, yes?

  patzer2: <Everett> Thanks for the correction. My habit of switching sides to look at positions on my analysis board sometimes gets me confused.
May-13-05  Everett: <patzer2> I was being petty, anyway. Thanks for the effort and analysis.
Aug-05-05  Averageguy: Did Seirawan simply miss blacks double attack 20...e4 or did he deliberately sac the exchange for good play? Many masters drop material in this fashion but win afterwards and say, "of course I saw that I saced it because it gives me a better position " when in reality they missed it and byluck managed to find some good resources. Of course, Yaz might have deliberatly given up the exchange, it's just something I'd like to know.
Sep-07-05  Brown: Seirawan suggests an improvement for white which he believes wins outright.

25.Rf1 Bh7 26.Rf6 Rfd8 27.g4 Kf8 28.Kg3 Ke7 29.Rh6 Rh8 30.g5

Seeing this line, perhaps blacks last chance to salvage this game is around move 23, or not take the rook in the corner at all on 21.

Feb-07-11  Everett: 25.Rf1 followed by 26.Rf6 looks like a positional crush. How is black supposed to get any play with his pieces? Interesting position.
