  Peligroso Patzer: FWIW with regard to my comments above re: “quartgrip”, if one considers the position after 47. … h4+!! 48. Kxh4 Kf3!:

… and if one now imagines that White could bring about the “quartgrip” formation in one move (instead on the three actually required), the following position (with Black to move):

would indeed be winning for White regardless of whether Black tries the zugzwang idea that worked in the actual game: 1...Kf2 2.b5 Ke3 3.c5 Kd4 4.c6 b6 5.axb6 or tries to run his King immediately through the center to the Q-side: 1...Ke4 2.Kg3 Kd4 3.h4 Kxc4 4.h5 Kxd5 5.h6 c5 6.bxc5 dxc5 7.h7 c4 8.h8Q .

What is wrong with 44.Bxe6 Kxe6 45.Bxg5?

44.♗e6 ♔e6 45.♗g5 looks pretty good to me, eg {45..hg4 46.Kg4) and White seems to have the advantage with the 2-1 pawn advantage on the Kingside.

Dec-27-09  WhiteRook48: 52...Kg2 53 c4 bxc4 54 b5 c3 55 bxa6 c2 56 a7 c1=Q 57 a8=Q Qe1#
Dec-27-09  randomsac: Nasty way to trap the white king.
Dec-27-09  SuperPatzer77: Instead of White's actual move of 49. b4, White's best try is 49. a5!? below:

Black's strong reply to 49. a5 is:

49...c6! 50. dxc6 bxc6, 51. c3 d5!, 52. b4 Kg2!, 53. h3 Kf3 (now White is in complete zugzwang) 53. b5 (desperate move) cxb5, 54. c4! b4!! (54...d4??), 55. cxd5 b3, 56. d6 b2, 57. d7 b1=Q, 58. d8=Q Qe1# 0-1

It is awfully tricky!!! It is not easy to solve that. It's almost mind-boggling!!

See that Black still has a tempo and puts White into zugzwang so, Vassily Ivanchuk (White) resigns.


Dec-27-09  ajile: Seriously what is the compensation for White in this opening with the doubled pawns? I'm not seeing it.
Dec-27-09  Starf1re: ajile: the compensation for the doubled pawns is white's half-open Q file, and Rybka suggests it as the main line after 4)nxe4....
Dec-27-09  ajile: lol

Just because Rybka has this opening loaded doesn't mean it's good.

Dec-27-09  The Rocket: "Seriously what is the compensation for White in this opening with the doubled pawns? I'm not seeing it."

open lines of course, and its really no weakness in the endgame....

Its hard to explain though to lower rated players who simply look superficually at the positions and see doubled pawns and suddenly think black is better.. its also about piece activity!! in fact the position is perfectly equal after both castle.

Dec-27-09  ROO.BOOKAROO: Everybody's ignoring <Atking'>s suggestion: Chuk's Wang! By far the best pun for this game, much better than the one chosen by CG. Bravo Atking! Let's keep all the subtleties of the language alive, instead of getting brain-numbed by unlimited transcriptions of computer analyses that do nothing to enhance our understanding of the effective psychology of the actual moves.
Dec-27-09  ajile: If it's perfectly equal then White has lost his normal opening advantage.

: /

Dec-28-09  SuperPatzer77: Instead of 49. b4, White's try is 49. a5!? c6!, 50. dxc6 bxc6, 51. b4 d5!, 52. Kh3 d4, 53. Kh4 Kg2!, 54. h3 Kf3, 56. c4 dxc3 e.p., 57. b5 c2, 58. bxa6 c1=Q, 59. a7 Qe1#

Wow, it is clever and tricky maneuver by Wang Yue!!


Dec-28-09  The Rocket: "If it's perfectly equal then White has lost his normal opening advantage."

no because sometimes the advantage is microscopic... which is why the petrov is hated by all e4 players.. because in practise the position is a dead draw right out of the opening unless one of the players decides to take risks.

Dec-28-09  ajile: Tg Zulkifli vs Lai Wendy, 1992

Just play this gambit by transposition.


1.e4 e5
2.Nf3 Nf6
3.Bc4! Nxe4

Of course the other option for White is to simply change the nature of the game into more strategic lines with moves like 2.d3 or 2.c3. White keeps lines closed and could also play a Philidor in reverse with the extra move. Pretty good chance this isn't the type of game a Petrov player is looking for or expecting.

Dec-28-09  ajile: An interesting note to the above game is that after 4.Bxf7+ Kxf7 5.Nxe5 Kg8 6.0-0 d6 7.Qe2 the huge mistake obviously is 7..dxe5 which loses instantly.

Instead either 7..Nf6 or 7..Qe7 win for Black.

Dec-29-09  limulus: "Wang Zugs"

I still remember when this pun came up for voting - probably the cleverest I've ever seen on CG.

Dec-31-09  gilbav: The pun that I have submitted for voting was slightly different - "Wang Zugz".

  kevin86: A problem-like zugzwang of white's king.
Dec-27-10  kevins55555: Someone's name...
Is Wang Zugs
Oct-03-11  LIFE Master AJ: A (former) Internet student sent me an e-mail and asked that I looked at this game ...

Amazing! Anyone care to clue me in on where Ivanchuk dropped the ball?

(4 wunce-a) Kool pun, BTW.

Oct-03-11  DanielBryant: This may be an elementary question, but why does Black offer the queen trade with 22...Qg5? White seems to get some play against Black's pawns, and the move does seem counter intuitive.

  Peligroso Patzer: <LIFE Master AJ: *** Amazing! Anyone care to clue me in on where Ivanchuk dropped the ball? ***>

The losing move appears to have been <44. Bxg5?>.

FWIW, here’s some analysis I worked out from the position after <43. … Ke5>:

click for larger view

<44.Bxg5?> [Better would have been: 44.gxh5 gxh5 45.Bxc6 bxc6 46.b4± Although White has some advantage here, his winning chances appear slight. Ivanchuk probably went astray because he was ambitiosly stll hoping for a win. For this purpose, it is pointless to grab a pawn with 44.Bxe6 Kxe6 45.Bxg5 because there are no winning prospects in the opposite-color-bishop ending, but this would have been a safe path to split the point, and therefore better than the text.]

<44...Bxd5 45.f4+> [45.cxd5 Nxg5 46.f4+ Ke4 47.fxg5 h4+ 48.Kxh4 Kf3–+ would transpose to the game.]

<45...Ke4 46.cxd5> [No better would be: 46.gxh5 Nxg5 47.fxg5 Bg8–+]

<46...Nxg5 47.fxg5 h4+! 48.Kxh4> [Also losing would be: 48.Kf2 b5 49.axb5 axb5 50.c4 bxc4 51.bxc4 Kf4! 52.Ke2 (52.h3 Ke4) 52...Kxg4 53.Kd3 Kxg5 54.Ke3 Kf5 55.Kf3 g5 56.h3 g4+ 57.hxg4+ Kg5–+]

<48...Kf3–+ 49.b4 b5 50.a5 Kg2 51.h3 Kh2> 0–1

Aug-04-14  Ke2: This is what can happen when you play out a "drawn" endgame. Great pun too.
Feb-24-15  engineerX: Wang Yue, the master of endgame tricks. He is comparable to Carlsen and the other greats in that part of the game, in my opinion.
Jul-26-15  Ke2: This is such a great trick.
