Nov-27-07  s4life: agreed. This was a nice game by W. Hao... his 25th was a 18-ply depth combination and it worked! Pono never saw that coming until it was too late.
Nov-27-07  chessmoron: As Chinese would say: HAO! (Good Job!)

  refutor: great win by Wang Hao!
Nov-27-07  pawnofdoom: Something is definitely wrong with Pono. But truthfully, I hope that unlike with Hossain, he doesn't win the next game and ttiebreaks. I hope that the Chinese players, especially the really young ones like Wang Hao here, make it far. Wang Hao has been improving well and I hope he soon follows Wang Yue and possibly Bu into the 2700s.

Yes, he must have calculated out to 35 ... b5-b4 when he played 25 ... ♕b3x♖d1!!, else his knight gets <TRAPPED> on the enemy side of the board on d1.

Very little branching factor but still a deep combination. Ponomariov with his 2700-rating completely overlooked it.

Nov-28-07  Bobsterman3000: 24. Qf1 seems pretty weak and useless, especially after having already separate the rooks with 23. Re3. There's got to be a better move available at that critical juncture, but I don't have Fritz right now :-)
Dec-01-07  notyetagm: I just love the combination that Wang Hao played in this game, beginning with the thunderbolt 25 ... ♕b3x♖d1!!.
Dec-24-07  notyetagm: One of the best games of 2007.
May-22-08  dumbgai: Typical Ponomariov, playing out a hopeless endgame just to spite his opponent.

The point: a winning endgame.

Just beyond brilliant.

  coachjay: Can anyone name some other games with the same tactical theme of a sacrifice followed by a back-rank pin that cannot be avoided due to mate? I'd like to collect a few. Thanks.
Jan-12-11  Julian713: How do players see stuff like that...the queen sac/combination reminds me of something Tal would do.
Jan-12-11  Llawdogg: Wow! Great win for Wang. Beautiful queen sacrifice.

is Ponomariov vs Wang Hao 2007 G4, White 7? Black having just played a6-a5.

It is remarkable that Black can find the time to play a6 and then a5 within his first 6 moves - and that White cannot take advantage.

In the 2007 World Cup Ponomariov and Wang Hao met four times, Ponomariov winning 2-1 with one draw. Their first game Ponomariov vs Wang Hao, 2007 also began 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 a6 - and that time Ponomariov was the one to win with a Queen sacrifice. In the present game, Ponomariov varies - and loses.

Jan-12-11  matif: Not a monday morning puzzle (nor a sunday). Estupando!!!
Jan-12-11  gtgloner: What is the point of White playing beyond move 32? His opponent is Elo 2643!! Does white not think that 2 connected passed pawns can be brought home by opposition of that magnitude?
Jan-12-11  kellmano: <Coachjay> A similar motif is found here:

Seirawan vs Timman, 1990

  kevin86: Who would ever have thought that the f-pawn would be the one to queen.

The final position finds the bishop with no move to stop the f-pawn

77 ♗f2 h2+ 78 ♔xh2 ♔xf2 the the pawn will queen.

Jan-12-11  haydn20: I suspect Hao's antennae began quivering after W refuses the Q trade with 18. Qb1. Now B has all the open lines and W is passive, to say the least.

  Chessmensch: It took a couple of minutes, but Deep Fritz 12 found 25...Qxd1. However, at Depth = 26, it rates Qxa4 better, but just by a trifle of a trifle -1.26 vs. -1.23.
Jan-12-11  WhiteRook48: 25...Qxd1 is a great combination.
Premium Chessgames Member
  ajile: 23.Re3 seems to be where White lost it although 22.c5 was also not good.

Either 23.Rd1 or 23.Re2 was at least only a slight edge for Black. After the move played 23.Re3? Black is building serious threats with 23..Qd5! White's back rank is very vulnerable.

  coachjay: Kellmano - Thanks!
May-21-13  Blunderdome: OK, this was good.
