Aug-23-07  THE pawn: Ouch, very brutal exchange sacrifice.
Sep-01-07  coastalferg: interestingly this exchange sacrifice has occured only once before in the database and wang hao was playing the blacks, guess this game made an impression on him M Vachier Lagrave vs Wang Yue, 2006

  IMlday: His mind probably played 24..Nc4 followed by 25..Nf6 but his hand reversed them.
Sep-02-07  Manic: <IMlday> Ian Rogers says after 24...Nc4 25.Qg5 Nf6 26.Nh4 is winning. Perhaps he wanted to try and stop the attack by sacrificing, or he missed 26.Nxf6
Sep-02-07  Kwesi: <coastalferg> aren't Wang Hao and Wang Yue two different people?
Sep-03-07  notyetagm: <Kwesi: <coastalferg> aren't Wang Hao and Wang Yue two different people?>

Yes, Wang <Yue> was the victim of the MVL novelty while Wang <Hao> employed that same novelty here to defeat Timofeev in a very one-sided game.

Sep-03-07  notyetagm: 27 ♕a5-d2! is a lovely move, preparing the <PAWN FORK> d4-d5 if Black takes the White e6-bishop. That is, 27 ... ♖e7x♗e6? runs into 28 ♖e1x♖e6 ♕d6x♖e6 29 d4-d5 and the White d5-pawn <FORKS> the Black c6-rook and e6-queen. Note that the attempt to get out of the <PAWN FORK> by <PINNING> the White d5-pawn to the White d2-queen fail because the White f3-knight <DEFENDS> the White d2-queen so that the White d5-pawn is =not= obligated to <BLOCK> the d-file.

So even though the White e6-bishop is attacked three(!) times (Black e7-rook, d6-queen, and c6-rook) and defended only once(!) (White e1-rook), Black cannot(!) capture it because he will make a <PAWN FORK ALIGNMENT> if he does! It's just like NM Heisman says, chess is not just counting.

I call this concept <DEFENSE BY MISPLACEMENT> and here Wang Hao provides a perfect example of this tactical idea: if Black captures the White e6-bishop, then he has created an <ALIGNMENT> for a <PAWN FORK> which loses material; hence the White e6-bishop is taboo and cannot be captured.

Sep-03-07  notyetagm: This is really a beautifully played game by Wang Hao, especially tactically.

Notice in particular that after 25 ... b7-b6, threatening the White a5-queen, Wang Hao (White) ignores the threat to his queen and plays the strong <ZWISCHENZUG> 26 ♘d5x♘f6!, making a stronger threat than the one that Black just made with his b-pawn push.

The obvious point of 26 ♘d5x♘f6! is that 26 ... b6xa5?? 27 ♘f6x♖e8+ followed by 28 ♘e8x♕d6 will leave White two pieces(!) ahead.

Wonderful tactical alertness by Wang Hao.

Sep-03-07  notyetagm: 27 ♕a5-d2!, protecting the White e6-bishop indirectly by threatening the <PAWN FORK> d4-d5, is the best example I have ever seen of the tactical concept of <DEFENDED BY <MISPLACEMENT>; that is, the opponent cannot capture a piece (it is =taboo=) not because his capturing piece will become <LOOSE> but because his capturing piece will make some kind of <ALIGNMENT> (here a <PAWN FORK ALIGNMENT>) if it goes ahead with the intended capture.

  IMlday: 24..Nf6? loses a piece and is quite hopeless. After 24..Nc4 (box) 25.Qg5 Nf6 26.Nh4 Qxe6 (box)27.Rxe6 Rxe6 favours White, but not necessarily decisively. At least the material is 2♖s vs ♕+p which is a big improvement on being down a piece. In any case, a good game illustrating that fortune does favour the bold.
Sep-07-07  coastalferg: <kwesi> lol yes i suppose they are ok so this exchange sac only happens when wang's are playing
Jan-25-09  WhiteRook48: 26. Nxf6 is great, I think I would have clumsily moved my Q back had I not seen this game
Oct-23-19  Dave12: <coastalferg: interestingly this exchange sacrifice has occured only once before in the database and wang hao was playing the blacks, guess this game made an impression on him M Vachier Lagrave vs Wang Yue, 2006> MVL used this idea again against Ding Liren's Caru Kan M Vachier-Lagrave vs Ding Liren, 2013
